Technical Datasheet
 
Product Description
 
SunSheetal™ is, polymer-acrylic blended, elastomeric, water based, high thermal emittance, ceramic coating useful as a Roof/Exterior coating that has the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, thereby reducing heat transfer to the building. SunSheetal™ is a high performance non toxic, high emissivity, ready-to-use High Albedo : Heat Reflective paint coating which significantly lowers the surface temperature of your roofs and structural exteriors. SunSheetal™ exceeds LEED, Energy Star and IGBC cool roof specification and has a measured and certified Solar Reflectance Index (SRI) of 108 (certification from CRRC accredited lab, USA) using LEED certified ASTM methods.

APPLICATION GUIDE
 
Surface Preparation
 
1. All surfaces must be thoroughly cleaned and free of all dirt, loose and flaking paint or any other material which may impair adhesion.
 
2. Power jet washing and/or mechanical means such as wire brushing can be used.
 
3. Surface cracks of more than 2 mm and separation gaps should be filled up with modified mortar or as specified.
 
4. Cleaned area to be washed with water.
 
5. The surface should be moist & clean before application.
 
Application
 
1. Stir the paint thoroughly before use.
 
2. Apply first coat with spray/brush/roller on the cleaned & washed surface.
 
3. Apply second coat after a gap of minimum two hours.
 
4. Ensure that the coated area does not come in contact with water for a minimum three hours.
 
5. After completion of full coating, 24 hours is the (self) curing period for this paint.
