What is RCC Roof Paint?
RCC Roof Paint, commonly referred to as Concrete Roof Paint, Terrace Cool Coat, or High Albedo Concrete Coating, is a water-based acrylic and nanotechnology coating designed with high solar reflectance and thermal emittance properties for cement surfaces. While conventional terrace paints tend to absorb the infrared rays of the sun and warm up the concrete slab, RCC roof paint reflects most of the sun’s energy into the atmosphere, thus maintaining a cool concrete surface and every space under it.
The COOLROOF® Paint obtains 95% Solar Reflectance and 91% Thermal Emittance on RCC and concrete surfaces. Hence, its SRI value is 122, far surpassing the minimum standard of 78 required for qualifying as a high SRI concrete roof paint for green buildings.
How Does RCC Roof Paint Work?
RCC roof paint operates on the principles of Solar Reflectance Index (SRI). The sun provides visible light, infrared, and ultraviolet rays. The black or uncoated concrete roof absorbs the energy and converts it into heat, which further radiates inside the building for many hours – sometimes even at night – thus making the operation of ACs more difficult. A paint having a high SRI value is created using reflective pigments and nanotechnology
- Reflects up to 95% of the solar radiation back
- Absorbs the energy and re-emits the heat rapidly due to high thermal emittance
- Forms a thermal barrier preventing the penetration of heat in the slab
- Cools down the terrace surface up to 20°C compared to un-coated RCC roofs
Key Benefits of RCC Roof Paint
1. Cooler Top Floor Areas
RCC roof paint acts as an effective barrier to solar heat right at the concrete surface, helping keep ceilings and top floor rooms cooler. This is of particular benefit for houses, apartments, and office buildings with RCC terraces.
2. Lowered Cooling Expenses
With reduced solar heat reaching the building via the slab, the cooling requirements for the building decrease. RCC roof paint can reduce cooling expenses up to 30%.
3. Waterproofing for RCC Terraces
4. Crack Resistance and Increase in the Life of the Roof
The expansion and contraction of the RCC slabs due to continuous heating and cooling cycles will be minimised due to the application of concrete roof paint, thus ensuring that the roof lasts for a longer time.
5. Eco-friendly Construction and Sustainability
Coolroof® is one of the few high albedo RCC roof paints available for GRIHA and IGBC certifications in India, thus making concrete roofs eco-friendly and earning green building credits.
Where Can RCC Roof Paint Be Applied?
One of the biggest advantages of RCC roof paint is its versatility across almost every cement-based roofing surface used in India:
- RCC terraces, concrete slabs and flat cement roofs of homes, villas and apartments
- Commercial and institutional buildings with concrete roofing
- Podium decks, parking terraces and exposed concrete slabs
- Industrial and warehouse buildings with RCC roofing — see our guide on heat reflective paint for metal & GI roofs if your facility has mixed metal roofing too
- Any concrete surface where reducing solar heat gain and improving waterproofing is required — see our general overview of cool roof paint for roofs for other roof types

RCC Roof Paint vs Traditional Concrete Roof Paint
A normal cement paint or waterproofing coating is intended primarily for decorative purposes and to make the slab somewhat water-resistant. However, it is not capable of inhibiting thermal conductivity in any way. RCC roof paint was created particularly with regard to solar reflection and thermal insulation. This is due to the special technology used to manufacture these paints and the application of particular nanoparticles which are not used in normal concrete roof paints.
Industries & Buildings That Benefit from RCC Roof Paint
RCC roof paint is widely used across buildings with concrete roofing. COOLROOF® has been trusted by organisations such as Indian Oil, Indian Army, RBI, Google India, Godrej and Blinkit for large-scale RCC and concrete roof cooling projects.
How to Apply RCC Roof Paint
- Surface cleaning — remove dust, algae, moss and loose debris from the terrace
- Crack filling and levelling of uneven patches on the concrete surface
- Priming (recommended if the concrete is highly porous or previously untreated)
- Application of 2–3 coats of cool roof paint using brush, roller or spray
- Curing period before the roof is exposed to heavy rain or foot traffic
For best, warrantied results, COOLROOF® offers full turnkey application services — including site inspection, material supply and professional installation.

Signs Your Roof Needs RCC Roof Paint
Don’t know if you need RCC roof paint on your terrace? Well some usual indicators can help you recognize too much exposure to sun and stress of the concrete: if your upstairs rooms remain hot even after the sun sets down, if your terrace is too hot for walking barefoot in the middle of the day, if new cracks appear in summer every year, if there are wet spots on your ceiling beneath your terrace, or if your electricity bill goes through the roof every summer.
Maintenance Tips for RCC Roof Paint
The RCC roof paint is known to be very low maintenance. However, some basic practices will ensure longevity and maintain the reflection qualities:
- Periodically clean the terrace to avoid accumulation of dirt and pollution that can affect reflectance
- Check the roof for cracks and blistering after monsoon and rectify immediately
- Make sure the drainage system remains unclogged to avoid accumulation of water on the terrace
- Do not keep anything heavy or sharp on the painted roof
- Have the roof recoated professionally after several years for high pedestrian and sun-exposed terraces
RCC Roof Paint and Energy Efficiency Ratings
With the rise of energy-efficient codes and green buildings in India, RCC roof paint has emerged as an accepted solution to increase energy efficiency ratings of a building. Since it needs no electricity, has no moving parts, and comes with zero operating cost, RCC roof paint such as COOLROOF® is one of the best solutions available that gives the best ROI of all other energy-efficient measures.
Asbestos cement sheets: RCC roof paints
Asbestos cement sheets have an ability to trap heat and become a source of discomfort in the hot season. To make your indoor space cooler and reduce cooling expenses, you can apply high-quality RCC roof paint such as COOLROOF®, which will reflect solar radiation, decrease the temperature of the roof surface and prevent heat flow into the building. It will increase indoor comfort, reduce heating expenses and help asbestos cement roofing last longer.
For Concrete Roofs: RCC roof paints
Concrete roofs can attract and hold much sunlight. It causes excessive heating inside your house and raises air-conditioning costs. High-quality RCC roof paints such as COOLROOF® provide your roof surface with a heat-reflective layer. It will decrease the temperature of the surface, enhance the comfort of your indoor space and improve building energy performance. Also, it will protect your roof from UV radiation and rain.
