Insulating Paint Additive

Frequently Asked Questions

Q: What is the R value of Heatshield-R20?

A:  There is no R value to any radiant barrier paint some companies claim an R value or an equivalent R value We Make No Such Claims. What we do claim is that we will meet or beat any other paint additive on the market and our test show that we are within one or two degrees of aluminum foil radiant barriers. Please go to HOW IT WORKS


Q: How much savings can I expect when I use Heatshield-R20?

A: The more you use, the more you'll raise your thermostat in the summer.  With your attic and some walls you can expect 3 to 5 degrees savings in the summer. In the winter you'll lower your thermostat about 3 to 5 degrees

Q: What kind of paint will Heatshield-R20 work with ?

A: Heatshield-R20 is compatible with all Interior and Exterior paints: Water base, Oil base, Urethane, Epoxy, etc.


Q: How much coverage will I get per gallon.
A: You should get about the same coverage as your paint without Heatshield-r20 but will go on thicker.


Q: How many coats of paint should I apply?

A: One or more coats of paint to achieve about 4 to 5 mills in thickness. Where coatings are expose to harsh elements we suggest a prime or tack coat of untreated paint before coating with Heatshield-R20  ( to increase adhesion)

Q: Can I paint over Heatshield-R20?

A: Yes! But Heatshield-R20  is always more effective  as a top coat. For the best energy efficiency use Heatshield-R20  inside & outside but either application alone will give increased energy efficiency.


Q: How much Heatshield-R20 do I need?

A: 4 oz. for one gallon of paint.

Q: What coverage can I expect?                                                                                    

A: You will get close to the normal coverage of the paint your using but will apply a little thicker.
You can figure approx. 300 square feet per gallon for most house paints at less than 5 cents per sq. ft cost, approx. 200 sq. ft. per gallon for attics and in elastomeric roof coatings generally cover a minimum of 100 sq. ft. per gal.


Q: How will Heatshield-R20 effect my paint?

A: There will be a slight more texture. Sheen will drop 1 gloss level. As in any additive this could effect your paint properties. If in doubt, always run test sample.

Q: What color paint should I use? 
A: White is always the color of choice, the lighter the color the better the performance.Darker color paints may lighten with Heatshield-R20.  

Q: I live in a northern climate, will Heatshield-R20 work for me? 
A: Yes: Heat travels to cold! The heat inside is trying to escape to the cold outside air. Heatshield-R20  on your interior walls and ceilings will help stop this outward heat loss. 

Q: Will Heatshield-R20stop the condensation on my 
metal building ceiling? 
A: Heatshield-R20  will reduce heat travel and moisture in the heat that is trying to escape through the outer cold surface and will reduce condensation on your roof underside. 

Q: Can Heatshield-R20 treated paint be sprayed? 
A: Yes: Remove all filters from your spray equipment (as they filter out Heatshield-R20 and use a slightly larger tip than 
normal .017 .019.  Elastomeric Coatings Require .028 to .032It is always recommended to filter paint before use.

Q: Can I use Heatshield-R20 in my attic? 
A: Heatshield-R20  applied to underside of roof decking will reduce heat gain in your building & will lower the surface temperature of insulation making it more efficient in controlling heat gain. This is probable the best single area to use Heatshield-R20.


Great USE for those left over paints
When completed it should have an even appearance with very minimal shadowing of the roof decking we recommend that all rafters be coated and the upright supports coated about 1 foot down from roof decking, 
as these all conduct and hold heat.Attics are very dry and absorbent and in most cases require two coats.

Q: Is there any special preparation necessary to use Heatshield-R20? 
A:  No, but always apply your paint to a clean dry surface. 

Q: Will more than one measurement per gal. of paint increase Heatshield-R20 effect on heat transfer? 
A: Yes but always run a test for adhesion 

Q: What other benefits will Heatshield-R20 give? 
A: With a Mohs 7 * hardness and spherical shape contribute to increase hardness and burnish/abrasion resistance of the finished surface.


* Talc = 1 Mohs Steel= 5 to 8.5 Mohs Diamond = 10 Mohs
