Yes, it does. This type of paint works just like bright-colored clothing (preferably white) on sunny days. This paint is made to reflect a lot more sunlight than it absorbs. It also admits little heat compared to standard roofs.
These paints are able to do this because they have highly reflective aqueous coatings based on acrylic resin. Reflective paint increases emissivity on surfaces like cement, asbestos and MS roofing by bouncing off the heat and light energy from the sun. It is also eco-friendly, so it is safe to use.
When applied uniformly, this paint forms an effective heat blanket, meaning little or no heat at all escapes the house when it’s cold.
Heat reflective paint was designed to reflect sunlight while absorbing little heat compared to standard roofs. When you apply this paint to your roof, it reduces your roof’s and room temperatures correspondingly. By lowering the temperature gradient across slabs, homes with A/C consume less power.
Benefits heat of Reflective paints:
Reflective paints resist infrared and ultraviolet rays continuously. This action results in an extreme reduction of heat on the roof. The coated area becomes comfortable even in extreme seasons like summer, especially in the afternoons. Most heat from the sun is reflected in the atmosphere.
These paints eliminate the need for installing a false ceiling.
They are compatible with any kind side walls and roofing materials.
They prevent the island effect.
As mentioned earlier, these paints are eco-friendly. They reduce greenhouse emissions hence prevent global warming.
They also have chemicals which prevent algae and mold build up, especially for those roofs installed in warm, moist locations.
They also have no solvents in them, so they clean up with water easily and they no toxic substances in them.
How can you apply this paint?
Clean ores with water or bleaching powder if necessary. Mix your paint thoroughly before every use.
Apply your first coat using a clean brush on a clean surface. The surface could also be washed prior to the application.
The second coat should be applied after 3 to 4 hours, ensure that for the next two hours or so, your previously coated surface does not come in contact with water.
You should also provide ample time for curing, just after finishing the application. Watch out for any damages at this point.
This paint can be applied via spraying, using a brush or a roller.
The best thing about this paint is that it is easy to apply and it replaces other bulky conventional or standard insulation methods.
What’s the best reflective paint to use?
When purchasing reflective paint, you want to go for those with SRI ( Solar Reflective Index) values between 121-123. SRI incorporates both thermal emissivity and solar reflectance. It is simply the ability to reflect light and heat instead of absorbing them. 122 is a good SRI value for reflective paints.
You should also purchase paints with standard Volatile Organic Compounds. Standard reflective paints will have their VOC values between 1.2 and 1.34 g/ltr.
