Primax Roof Coat – Heat & Weather Resistant Protection for Roof Surfaces
Roofs in Pakistan remain exposed to intense sunlight, high temperatures, rain, and changing weather throughout the year. Choosing the right protective coating can help improve roof performance while providing a clean and durable finished surface.
Primax Roof Coat is an extremely durable, heat-resistant, and weather-resistant roof coating developed for long-lasting protection. It is a self-priming, acrylic resin-based, water-borne topcoat designed for suitable roof surfaces where heat control, weather resistance, and dependable adhesion are required.
Its elastomeric properties, low VOC content, and ability to help lower roof and interior temperatures make it a practical solution for residential, commercial, and other suitable roof applications.
Why Roof Protection Matters
A roof receives some of the highest levels of direct environmental exposure in a building. Continuous sunlight can increase roof temperature, while rain and changing weather place additional stress on exposed surfaces.
Primax Roof Coat is designed to provide a protective coating layer that combines heat resistance, water resistance, weather resistance, and adhesion. Its white finish also supports the product's intended roof-coating application while helping create a clean and uniform appearance.
Key Benefits
- Heat Resistant: Designed to provide heat-resistant roof protection.
- Helps Lower Temperature: Helps reduce roof and interior temperature.
- Weather Resistant: Developed to withstand exposure to outdoor weather conditions.
- Water Resistant: Elastomeric formulation provides water-resistant performance.
- Excellent Adhesion: Designed to adhere effectively to suitable prepared roof surfaces.
- Self-Priming: Acrylic resin-based self-priming formulation.
- Low VOC: Contains very low VOC content.
- Multiple Surface Compatibility: Suitable for plaster, concrete, wood, and terrazzo roof tiles.
- Water-Borne Formula: Clean water is specified as the thinner and cleaner.
Suitable Roof Surfaces
Primax Roof Coat is suitable for a variety of correctly prepared roof substrates, including:
- Plaster surfaces
- Concrete roofs
- Wooden surfaces
- Terrazzo roof tiles
The condition of the substrate remains important for coating performance. Surfaces should be properly prepared before application so the coating can form a consistent and stable protective layer.
Heat Protection for Exposed Roofs
Direct sunlight can cause roof surfaces to absorb substantial heat during warmer months. This heat can contribute to higher temperatures inside the building, particularly where the roof receives prolonged daytime exposure.
Primax Roof Coat is formulated to help lower roof and interior temperature while providing a protective coating over the roof surface. This makes it particularly relevant for buildings exposed to Pakistan's hot summer conditions.
Actual temperature reduction can vary depending on roof construction, existing insulation, coating thickness, weather conditions, building design, ventilation, and surrounding environmental factors.
Elastomeric & Weather-Resistant Performance
Primax Roof Coat has elastomeric, water-resistant, and weather-resistant properties. These characteristics help the coating perform on roof surfaces exposed to environmental conditions.
Its formulation is developed to combine surface protection with flexibility and weather resistance, providing a practical finishing system for suitable roof applications.

Available Pack Sizes
Primax Roof Coat is available in:
- 4 L
- 16 L
The suitable pack size can be selected according to the total roof area, substrate condition, required number of coats, and expected material consumption.
Spreading Rate
The stated spreading rate of Primax Roof Coat is:
- 0.5–0.8 kg/m² per coat
- 0.074 kg/sq. ft
Actual material consumption may vary depending on roof texture, porosity, surface profile, coating thickness, application technique, and site conditions.
Rough or highly absorbent surfaces may require more material than smooth and properly prepared substrates.
Surface Preparation
Good surface preparation is essential for achieving reliable adhesion and uniform roof protection.
- Remove loose material, dust, dirt, and surface contamination.
- Ensure the roof surface is sound and suitable for coating.
- Remove weak or poorly adhering previous coatings where necessary.
- Repair damaged areas before applying the roof coating.
- Make sure the surface is properly prepared before application.
The product is described as self-priming; however, the condition and type of the existing roof substrate should still be assessed before application.
Application Guidance
- Inspect the roof and identify any damaged, loose, or contaminated areas.
- Clean the surface thoroughly before coating.
- Ensure the substrate is properly prepared and suitable for application.
- Mix Primax Roof Coat thoroughly before use.
- Apply the coating evenly over the roof surface.
- Maintain sufficient material application according to the stated spreading rate.
- Allow the first coat to dry for the recommended period.
- Apply the further coat according to the stated “coat on a coat” system.
- Allow approximately 24 hours before recoating under the specified conditions.
- Clean application equipment with clean water after use.
Recoating Time
The stated recoating time for Primax Roof Coat is 24 hours.
Actual drying and recoating conditions may be influenced by temperature, humidity, ventilation, film thickness, roof temperature, and weather conditions during application.
Each coat should be sufficiently dry before the next coat is applied.
Water-Borne & Very Low VOC
Primax Roof Coat is a water-borne acrylic emulsion coating with very low VOC content. Clean water is specified as the thinner and cleaner, making equipment cleanup more convenient after application.
Common Application Mistakes to Avoid
- Applying over a dirty roof: Dust, dirt, and loose material can interfere with proper adhesion.
- Ignoring damaged areas: Existing roof defects should be properly repaired before applying the coating system.
- Applying an excessively thin layer: Follow the stated spreading rate rather than stretching the material beyond its intended coverage.
- Recoating too early: Observe the recommended 24-hour recoating period.
- Painting during unsuitable weather: Environmental conditions can influence drying and coating performance.
- Skipping surface inspection: Different roof substrates may require different preparation before coating.
