## Overview

Barrier Coat is a 1-gallon, water-based radiant barrier paint featuring ground metallic aluminum pigment and insulating microspheres. It reduces attic heat gain by up to 42%, is 0% VOC and solvent-free, permeable to prevent moisture buildup, and suitable for interior and exterior surfaces. This eco-friendly, low-odor coating enhances insulation performance while being easy to apply and clean.

## Description

Barrier Coat is an insulating, radiant barrier paint made of ground metallic aluminum pigment and blended into an acrylic resin along with Hy-Tech’s ThermaCels, blend of insulating microspheres. Barrier Coat is designed for use as a radiant barrier coating for attics. It can also be applied to sidewalls to prevent “in-the-wall" condensation buildup due to water vapor transmission. The elimination of "in-the-wall" condensation improves existing insulation properties by keeping the insulation dry. Wall vapor barriers also eliminate peeling paint caused by vapor transfer from inside to outside wall surfaces. Tests show that radiant barriers can reduce summer ceiling heat gains by up to 42% compared to an attic with the same insulation level and no radiant barrier. Barrier Coat boasts a pure 0% VOC pigment, is water-based, and environmentally friendly.

Review: Works good. - With the heat in middle TN I wanted to insulate the garage doors. I put this on first and have order the insulation panels to go over this. I must say that 2 coats on the doors made a huge difference already.
Review: I hope this is what I ordered... - I need this to work for the inside of the roof on my school bus. The product itself sounds like it will be what I need. when I ordered it, What arrived was a flat black plastic can with a printed piece of paper glued to it.

## Features

- Contains no harmful solvents
- No VOC

## Questions & Answers

**Q: Will this help with metal roof condensation**
A: It can, but there are many factors involved including where it's applied. We've had people consider painting this on top of the roof, for example, which is not what it is intended for.
Best thing that can be done is to apply our Roof Guard to the outside of the roof, primer with our ceramics mixed in on the underside of the roof, then the Barrier Coat. If painting the outside of the roof is not an option then primer with our ceramics mixed in should be applied to the inside. Top coat this with multiple coats of our RC 233 industrial elastomeric coating. It has twice the amount of ceramics as our other coatings, and will remain flexible enough to withstand the expansion and contraction of metal.

**Q: Is this a good product to use in a garage (with a bedroom above it)? I'm looking for ways to reduce the temperature in the bedroom above the garage**
A: This is actually a very common question. The answer is absolutely yes, this is a perfect product for that application. One to two coats of Barrier Coat, top-coated with two coats of our Insulating Ceiling Paint (has twice the loading of ceramics) can make a major difference.

**Q: Inside or outside for 2 of 4 walls in an open porch?**
A: The best results would come from painting both because it would deal with heat / cold from each side. If painting only one side the interior would be beneficial.

**Q: Can it be rolled or brushed on?**
A: Hello. Yes brush, roller, or spray as with any conventional paint.

### ⭐⭐⭐⭐⭐ Excellent barrier coat for your attic

Spec says you have to have a 1 gallon per minute or larger airless to spray but I applied with a Graco 395 with all filters removed and a 319 tip
