Frequently Asked Questions

Showrooms usually use brighter, more balanced lighting than homes. Your room may combine strong daylight, shaded corners, warm evening LEDs, and reflective flooring, so the same white can look cleaner, warmer, or duller depending on the time of day.

The most likely cause is skipped preparation. Painting directly over unprimed, highly alkaline plaster or failing old paint prevents a proper bond. In the Saudi climate, these skipped steps lead to rapid delamination (the paint lifting away). Always use an alkali-resistant primer on new walls.

No. Paint is a thin coating, not a structural filler. Cracks will "telegraph" through new paint almost immediately as the building naturally moves with temperature changes. Use a dedicated crack filler, and for exterior walls, use an epoxy-based filler that handles thermal expansion.

Yes, if you want a professional result. Sanding removes "nibs" (small bumps) and creates a surface that primer can grip. It is especially vital if you are switching from a glossy old paint to a new matte finish, or vice-versa.

Moisture is the enemy of paint. Ensure the substrate is completely dry before starting. Use a moisture-resistant primer and a high-quality topcoat with anti-fungal properties to prevent mold growth in humid coastal conditions.

Pure white paint is formulated with minimal tinting pigments, yielding a high Light Reflectance Value (LRV) typically above 90, making it highly luminous and ideal for ceilings. Off-white paint contains small amounts of yellow, red, brown, or grey pigments, creating subtle undertones that soften the color, reduce glare, and help the paint layer harmonize with residential lighting and flooring materials.

Residential LED lamps with warm color temperatures, such as 2700K, emit a distinct yellow cast. This yellow light acts as a filter, amplifying the yellow or cream undertones in warm off-whites, making them appear richer and more golden. If applied to cool white walls with blue undertones, the opposing light and pigment colors clash, often creating a dull, muddy grey appearance.

Commercial showrooms utilize balanced lighting systems engineered between 4000K and 5000K to simulate accurate daylight, which stabilizes paint undertones. Residential rooms rely on a mix of natural sunlight and warm 2700K artificial light, causing the paint layer to reflect different wavelengths. This physical shift changes how the human eye perceives the color throughout the day.

A flat matte or eggshell finish is highly recommended for hiding minor imperfections on wall surfaces. High-sheen paints, like semi-gloss, reflect light in uniform, mirror-like angles that emphasize surface wave and trowel marks. Matte and eggshell finishes diffuse light unevenly in multiple directions, successfully concealing minor physical variations in the underlying plaster layer.

Triadic and tetradic schemes use three to four colors by design. The key is hierarchy: one color dominates, others support or accent. When every color competes equally, the room feels chaotic. With proper distribution (60-30-10), four colors can work harmoniously.

Open floor plans require a cohesive thread across zones. The dominant color (60%) typically flows through the entire space on walls and large furniture. Secondary and accent colors can shift by zone, creating distinct areas while maintaining overall harmony.

Neutral palettes follow the same principles. Choose three neutral tones at different values: a dominant warm white or greige, a supporting taupe or soft grey, and an accent in charcoal or black. Texture becomes especially important when color variation is minimal.

Consider the room's natural light. North-facing rooms with cooler light benefit from warm-undertone colors that compensate. South-facing rooms with abundant warm light can handle cool undertones without feeling cold. Test samples in your specific lighting conditions.

Not necessarily. In calm, monochromatic schemes, the accent might simply be a deeper value of the same hue. In complementary schemes, even a muted version of the complementary color provides contrast. Bold accents suit energetic spaces; subtle accents suit restful ones.

In many majlis spaces, a warm off-white or a balanced neutral white gives the most comfortable result. Warm evening lighting, textiles, and wood details often make bright cool whites feel too sharp. Test both options on the wall before deciding.

They can be, but many interiors look better when the ceiling is slightly brighter than the walls. Keep both colors in the same undertone family so the ceiling does not turn blue or the walls look too yellow beside it.

Many white wall colors work well between about 80 and 88 LRV because they still read as white without feeling too stark. Very bright whites above 90 LRV often suit ceilings and smaller spaces better, though the final choice depends on lighting and room size.

Primer paint is a preparatory coating applied before the topcoat. The right type depends on the surface and the problem you are solving.

On new plaster, concrete, or cement surfaces, an alkali-resistant wall primer is required before interior or exterior painting. It seals the alkaline salts in new walls and provides a stable base for the topcoat. On new unpainted surfaces this step cannot be skipped.

Bare wood needs a dedicated wood primer. It seals the grain, prevents tannin bleed from dark timbers, and stops the topcoat from absorbing unevenly — giving the final finish a smoother, more consistent result.

Metal surfaces such as iron, steel, and aluminium need their own primer. The purpose here is corrosion protection and adhesion. Stain-blocking primer is used over stubborn marks — water stains, nicotine, tannin — that would bleed through a standard emulsion.

Paint-and-primer-in-one products are suitable only when repainting over a clean, sound, non-porous surface in a similar colour. They are not a substitute for a proper primer on new, bare, or stained surfaces.

Waterproof paint, also called elastomeric or waterproofing coating, forms a continuous flexible membrane that stops water from penetrating a surface. Unlike standard exterior paint, which slows moisture absorption without stopping it, waterproofing coatings stay flexible and can bridge hairline cracks that open and close with temperature change.

It is used most commonly on flat roofs and open terraces, where standing water, thermal expansion, and direct sun all attack the surface. A waterproofing membrane keeps moisture out of the building structure and must be flexible enough to move with the surface without cracking.

It is also used in bathrooms and wet rooms — on walls and floors around showers, baths, and toilet areas — applied either under tiles or as a direct finish in some designs. The same applies to kitchen floors and service areas where constant spillage and cleaning demand a surface that truly seals.

Below-ground and retaining walls exposed to soil moisture also benefit from waterproofing coatings, using the appropriate system for that type of exposure. Swimming pools and water tanks are a separate category; they require specialist systems, not standard waterproof paint.

A good waterproofing coating should be elastomeric (stretches and recovers without cracking), UV-stable if used externally, and rated for the water exposure level of the surface.

Metal primer is a specialised undercoat applied to bare metal before painting. Its primary purpose is corrosion prevention: steel and iron rust when moisture and oxygen reach bare metal, and metal primer forms a barrier that keeps them out. Standard wall primers do not bond well to bare metal and provide no rust protection, which is why using the wrong primer on metal is one of the most common causes of paint failure on gates, railings, window frames, and structural steelwork.

You need it on any bare, sanded, or newly welded iron or steel surface before applying a topcoat. It is also applied after removing rust and cleaning back to bare metal — because the topcoat alone provides no chemical protection to the exposed metal beneath.

Aluminium and galvanised steel need a different approach: a self-etching or bonding primer designed for non-ferrous metals, since standard iron primers may not adhere correctly to these surfaces and the coating can fail early.

Most metal primers contain corrosion-inhibiting pigments — typically red oxide or zinc phosphate — that protect the metal chemically even if the topcoat is later scratched. Clean and degrease the surface thoroughly before priming; primer cannot bond over contamination and any skipped preparation will show up as rust or peeling.

Paint types fall into two main families: water-based and solvent-based. Within each family there are several product types suited to different surfaces and purposes.

Water-based paints (emulsions, acrylics) are the most commonly used for interior and exterior walls. They dry quickly, have low odour, and clean up with water. They are available in finishes from matte to semi-gloss, and exterior acrylic formulations are designed to resist UV, rain, and temperature change.

Solvent-based alkyd paints are used where a harder, more durable surface is needed — doors, window frames, metal railings, and exterior trim. They dry more slowly and have a stronger odour but produce a tough, abrasion-resistant film. Nitrocellulose (naari) paint is also solvent-based but dries through rapid solvent evaporation; it is used mainly in furniture workshops and on decorative interior metalwork where fast turnaround matters.

Epoxy paints form a chemically resistant, extremely hard surface and are used on floors, workshops, and surfaces facing heavy use or chemical exposure. They are two-component products mixed before application. Waterproofing coatings form a flexible membrane that prevents water penetration and are used on exposed roofs, terraces, and wet rooms.

Primer is not a paint type — it is a preparatory coating that helps topcoats bond, seals surfaces, and prevents problems. Each paint type has its matching primer, and skipping it on new or bare surfaces is the most common cause of early paint failure.

Both oil (alkyd) paint and nitrocellulose (naari) paint are solvent-based — neither uses water as a carrier. But they differ significantly in how they dry, how durable the film is, and where each one belongs.

Alkyd (oil) paint dries through a slow oxidation process that takes several hours. It builds a hard, tough film that holds up well on exterior metal, gates, doors, window frames, and any surface exposed to wear or weather. It resists abrasion and moisture better than nitrocellulose over the long term.

Nitrocellulose (naari) paint dries almost instantly through solvent evaporation alone — no chemical reaction. This makes it the standard choice in furniture workshops and for decorative interior metalwork where fast re-coat time is essential. It produces a smooth, glossy finish, but the film is thinner and less durable than alkyd for exterior or high-wear applications. It is also more flammable and has a stronger odour; adequate ventilation is not optional.

Neither replaces the other. Use alkyd on exterior iron, gates, railings, and doors. Use nitrocellulose on interior furniture and decorative surfaces where speed of application is the priority. For interior walls, neither applies — the right product there is a water-based emulsion.

Profile paint is a textured exterior coating that creates a three-dimensional, patterned surface on facades. Unlike smooth exterior paint, profile coatings contain aggregates or special additives that produce a raised texture ranging from fine sand through to heavier decorative relief patterns. The term "profile" became widely associated with one branded product, but the category is produced by multiple manufacturers under different names.

It is used on the exterior facades of villas, residential buildings, and commercial projects where the design calls for a decorative textured finish rather than a flat painted surface. It is a standard finish across the Gulf region because it adds visual character to a facade while the extra coating thickness contributes an additional layer of weather protection.

Application is typically by roller or spray; heavier grades may require a trowel or patterned roller to achieve the desired effect. Surface preparation is more critical here than with smooth paint — cracks, weak plaster, or an unstable substrate will telegraph through the texture after application. A primer coat compatible with both the substrate and the profile product must be applied before texturing.

Profile coatings vary in aggregate size (fine, medium, coarse), flexibility, UV resistance, and whether they accept custom colour tinting. Choosing the right grade depends on the building type, its environment, and the facade finish specified.

Yes, walls can be painted in winter in Saudi Arabia, and in most regions the climate is mild enough that winter presents few significant challenges. The primary conditions to verify before starting are: the surface temperature must be above 5°C, the surface must be completely dry with no moisture from rain or condensation, and relative humidity should not be excessively high. For new plaster, wait a minimum of 28 days before painting — regardless of season — to allow full carbonation and moisture release. Failing to wait results in poor adhesion, alkali attack on the paint film, and premature peeling. In colder areas such as Tabuk and Abha, where temperatures can drop below 5°C at night, schedule exterior painting for midday when surfaces are warmer. Do not apply exterior paint if rain is forecast within 24 hours of application. Interior painting in winter requires adequate ventilation to allow water vapour from water-based paint to escape.

The material of the old paint must be removed, using sandpaper. Then, apply the decorative paint's primer. Finally, apply the final coat of paint.

The best colour for a living room depends primarily on the room's light conditions and size. For north-facing rooms with limited natural light, warm neutrals — soft whites with yellow or beige undertones, warm greys, and light terracotta tones — counteract the cool, flat light and make the space feel welcoming. South-facing rooms with abundant warm light can handle cooler tones — light blues, greens, and true whites — without looking cold. Neutral palettes built around off-whites, greiges, and warm taupes remain consistently popular for living rooms because they are versatile, easy to accessorise, and age well. If a stronger colour is desired, the most reliable approach is to apply it to one feature wall — typically the wall behind the sofa or the television — while keeping the remaining three walls in a lighter related tone. The 60-30-10 rule provides a practical framework: 60% dominant wall colour, 30% secondary soft furnishing colour, 10% accent.

Wall paints fall into two primary categories based on their binder and solvent system. Water-based paints — also called plastic paints — use acrylic emulsions as the binder and water as the carrier. They dry quickly (typically 1–2 hours to touch-dry), produce low odour, are environmentally cleaner, and are easy to clean up with water. Modern acrylic formulations match or exceed the durability of older oil-based products. Oil-based paints use alkyd resins as the binder and mineral spirits or thinner as the solvent. They produce a harder, smoother film with excellent levelling properties and strong adhesion on bare metal and wood. Drying time is longer — typically 6–8 hours — and the strong odour requires ventilation during application. Beyond these two families, specialised types include anti-bacterial paints, VOC-free formulations, textured decorative effect paints, heat-resistant coatings, and epoxy-based products for industrial surfaces.

Light and cool colours create the optical illusion of more space by reflecting light back into the room rather than absorbing it. Off-whites, pale greys, soft beiges, and pastel blues and greens are the most effective choices for making a small room feel larger. The key is to keep the colour value high — meaning choose the lightest shade of a given hue rather than a saturated mid-tone. Painting the ceiling the same colour as the walls, or one shade lighter, removes the visual boundary between the two surfaces and increases the perceived height of the room. Using a single colour throughout — walls, trim, and ceiling in closely related tones — creates a continuous surface that reads as larger than a room divided by multiple contrasting colours. Avoid warm, dark, or highly saturated tones in small rooms; colours like deep red, forest green, or charcoal draw the walls visually inward.

To calculate how much paint a room needs, measure the total wall area — multiply the width of each wall by the ceiling height and add the results together. Subtract roughly 2 square metres for each standard door and 1.5 square metres for each window to get the paintable surface area. Each Time Paints product lists its coverage rate on the product page, typically expressed in square metres per litre. Divide your total area by this figure to get the litres required for one coat. Most rooms benefit from two coats, particularly when painting over dark colours or bare plaster, so multiply by two. As a general reference, standard interior paints cover 10–14 square metres per litre. A typical bedroom of 30 square metres of wall area will need approximately 4–6 litres for two coats, depending on the product chosen.

Modern paint technology has expanded well beyond standard wall colours. Anti-bacterial paints incorporate silver-ion compounds or other biocides that inhibit mould, mildew, and bacterial growth — useful in bathrooms, hospitals, and kitchens. Thermal insulation paints contain hollow ceramic microspheres that reduce heat transfer through walls, helping maintain cooler interior temperatures in hot climates. Low-VOC and zero-VOC formulations minimise the release of volatile organic compounds during application, improving indoor air quality and making them safer for use in occupied rooms. Texture and decorative effect paints simulate stone, concrete, marble, or metallic surfaces. Fire-retardant intumescent paints swell when exposed to heat, forming a char layer that slows flame spread — required in commercial and public buildings by fire codes. Weather-resistant exterior paints are formulated to withstand UV radiation, temperature fluctuation, and moisture over extended periods.

New color trends vary, but natural and earthy tones like olive green, dark blue, and earthy browns are currently popular. visit our latest color collection (2024 color trends).

Both seasons are suitable for painting, with some practical differences. In Saudi Arabia's summer, high temperatures accelerate paint drying — which is generally positive for project speed, but temperatures above 40°C can cause paint to dry too rapidly, leading to brush marks, lap lines, or poor film formation. The ideal application temperature for most interior and exterior paints is between 10°C and 35°C. In summer, work on exterior surfaces in the early morning or late afternoon to avoid peak heat. In winter, lower temperatures slow drying time, which extends the working window and reduces visible brushstrokes. The main risk in winter is humidity and condensation: applying paint to a surface that is below the dew point or retaining moisture from previous rainfall leads to poor adhesion, blistering, and early peeling. For interior painting, both seasons produce equivalent results when proper ventilation is maintained and the surface is dry.

Matte paint has a flat, non-reflective finish that absorbs light rather than bouncing it back. This makes it effective at hiding surface imperfections — uneven plaster, minor cracks, or textural variations — since no sheen draws the eye to them. Matte is the most common choice for ceilings and bedroom walls where a calm, even look is the priority. Glossy paint reflects light strongly, producing a bright and durable surface that is easy to wipe clean. It is best suited for surfaces that receive frequent contact: doors, window frames, skirting boards, and furniture. The tradeoff is that high gloss amplifies every imperfection underneath, so surface preparation must be thorough before application. Between these two, flat and semi-gloss offer intermediate options — more washable than matte, less revealing of flaws than full gloss — making them practical for kitchens, bathrooms, and children's rooms.

Paint coverage — the area one litre can coat in a single application — varies by product type, formulation, and the porosity of the surface being painted. As a general guide, standard interior emulsion paints cover approximately 10–14 square metres per litre on a normal smooth wall. Textured paints and primers on porous surfaces cover significantly less, sometimes 6–8 square metres per litre, because the rough or absorbent substrate soaks up more material. The specific coverage for each Time Paints product is listed on its product page. To use coverage figures practically: measure your total wall area in square metres, divide by the product's listed coverage rate, and the result is the litres needed for one coat. For two coats — which most interior jobs require for opacity and durability — double the figure. Add 10% as a buffer for wastage, edges, and variations in surface absorption.

Flat paint has a low sheen that reflects light subtly without drawing attention to wall texture or minor imperfections. It is easy to wipe down, making it a practical choice for bedrooms, hallways, and children's rooms that see regular use. Semi-gloss paint has a noticeably higher sheen, reflecting significantly more light and creating a brighter, harder surface. Its moisture resistance makes it the standard choice for kitchens, bathrooms, laundry rooms, and any area exposed to splashes, steam, or condensation. Semi-gloss is also commonly applied to trims, door frames, and skirting boards where surfaces need to withstand repeated contact. The practical rule: choose flat for walls in living spaces, semi-gloss for wet areas and woodwork. If the wall has visible imperfections, flat's lower reflectivity is more forgiving than semi-gloss, which amplifies surface irregularities under direct lighting.

Putty is applied before painting to level the wall surface and fill minor imperfections such as hairline cracks, holes from fixings, surface porosity, and small irregularities left by plastering. It is not always necessary on every surface, but it is standard practice for smooth interior wall finishes. On new plaster that is already flat and even, a thin skim of fine wall putty improves the surface texture and provides a uniform base for paint absorption, resulting in a more consistent colour and finish. On older walls with visible imperfections, putty is essential before applying a topcoat. The correct sequence is: surface cleaning, putty application, sanding when dry, primer, then painting. Skipping putty on an imperfect surface means those defects will show through the paint, particularly under raking light from windows. Using putty adds time to the job but extends the lifespan of the paint film by eliminating stress points where cracking can begin.

Interior paint typically lasts 5–10 years on walls under normal residential use, with higher-quality acrylic paints lasting toward the upper end of that range. Ceilings, which receive less physical contact, can go 10–15 years between repaints. Exterior paint has a shorter lifespan — typically 5–8 years — because it is exposed to UV radiation, temperature fluctuations, humidity, and dust. In Saudi Arabia's climate, exterior surfaces face intense UV exposure and summer temperatures above 45°C, which accelerates paint film degradation; using UV-resistant exterior formulations extends the effective lifespan significantly. Surface preparation is the single biggest factor in paint longevity: paint applied to a properly cleaned, primed, and dry surface lasts considerably longer than paint applied over dust, moisture, or a failing previous coat. High-traffic surfaces such as hallways, kitchen walls, and children's rooms age faster and typically require refreshing every 3–5 years.

Choosing paint colours for a home works best when approached as a sequence rather than individual room decisions. Start with the largest fixed elements in the home — flooring, kitchen cabinets, tile — because these cannot be repainted and must anchor the colour palette. Select wall colours that relate to these fixed tones: pull a warm or cool undertone from the flooring and build the palette around it. For the overall home, choose a consistent base tone — typically a neutral — to use in hallways and transition spaces, so that moving between rooms feels coherent. Individual rooms can then have their own accent colour within that framework. Consider natural light per room: north-facing rooms benefit from warm-undertone neutrals; south-facing rooms can carry cooler tones. Test any shortlisted colour as a large sample patch — at least 30×30 cm — and observe it across morning, afternoon, and artificial light before committing.

Primer is a preparatory coating applied before the topcoat of paint. It serves several functions that directly affect the quality and longevity of the final finish. First, primer seals porous surfaces — new plaster, bare concrete, or raw wood — so that the topcoat is absorbed evenly rather than unevenly, which causes colour variation. Second, it improves adhesion: primer bonds mechanically to the substrate and provides a surface to which the topcoat can grip, reducing the risk of peeling and delamination. Third, stain-blocking primers seal tannin bleed from wood, nicotine, water stains, and other discolourations that would otherwise migrate through emulsion paints. For new unpainted surfaces, primer is always necessary. For repainting over an existing sound coat of paint in good condition, a full primer coat can sometimes be omitted — but any bare patches, repairs, or stains must be spot-primed before proceeding.

Wood surfaces require a different approach to painting than walls, depending on whether the goal is to preserve the natural grain or to cover it with a solid colour. For a natural wood appearance, a penetrating wood stain is the standard choice — it absorbs into the wood fibres, adds colour and depth, and does not form an opaque film on the surface. This is suitable for interior furniture, doors, window frames, and decorative wood panels. For a solid-colour finish that conceals the grain, an alkyd or acrylic enamel paint is applied after priming with a wood primer. The primer seals the porous surface and prevents tannins from bleeding through the topcoat. For exterior wood exposed to sun and rain, choose a product with UV stabilisers and moisture resistance. Proper surface preparation — sanding, cleaning, and drying — determines the adhesion quality more than the paint choice itself.
