Product Overview

United Coatings Roof Mate Base Coat is a water-based acrylic base coat and is part of the Roof Mate Coating System. It is the first coating layer prior to applying the top coat. It utilizes the latest advances in acrylic technology to act as both a primer and base coat. It is a Primer in that it improves adhesion of the top coat on all substrates and provides bleed blocking on asphalt roofs. It is also a Base Coat in that it builds film thickness necessary to protect the roof and therefore it counts as the first coating layer.
  • Water-based acrylic base coat
  • Breathable coating, allowing moisture vapor to pass through the film
  • Durable and mildew resistant
  • Part of the roof mate coating system
  • Apply evenly at a rate of 1.0 – 1.5 gallons/100 ft² (4.1 – 6.1 L/10 m²) per coat with a minimum of two coats

YOU WILL WASTE YOUR MONEY WHEN YOU BUY THIS PRODUCT
clearly written that this product stops bleeding on asphalt roofs. IT DOES NOT DO SUCH AT THING. WHEN YOU BUY IT FOR THIS PURPOSE YOU ARE FLUSHING MONE IN THE TOILET I have filed warranty claim . of course process, it's a pure waste of your time with an explanation not worth reading. implying that top coat its not GAF brand where picture clearly shows bleeding through entire roof surface. what a bunch of bureaucratic idiots I have had experience with only sample has been done with top coat and they twists things their way. WILL NEVER USE GAF PRODUCTS KNOWIG HOW THEY CARE FOR THEIR PRODUCT USERS!!!!!!!!!!!!!

Hi, we apologize for your poor experience with Roof Mate Base Coat. I can tell you that the product is tested to rigorous standards and is used by many professionals within the industry with a long history of success. We do recommend this product to help with bleed block protection on asphalt roofs but once dried a top coat such as GAF Roof Mate needs to be applied to get the full protection benefits. Without knowing more about your specific case, please reach out to our Technical team as they may be able to better guide you about the warranty process. The number is 877-GAF-ROOF (877-423-7663), Option 5. If there is anything else we can do to correct your unpleasant experience, please let us know. gaf

    Covers Well, Dries Quick, Seals Cracks
    Now that all of the repairs on the various roofs have been perform with the applicable Roof Mate products, it is time to apply the Light Gray Roof Mate Base Coat. I used the product right out of the five-gallon pail. It has about the same consistency as house paint...maybe a tad thicker. It covers well and is thin enough to seep into seams, small cracks, and other voids. In three-tab shingles it works it's way into the gaps between tabs, which is exactually what you need it to do. I applied this with an 1-1/2" thick roller. I just dipped it into the bucket and began working onto the roofing surface. It does drip from the bucket to the work area, but you can come back and smooth out the drips. Just keep the bucket near your work. The coating dried to the touch in about 2-hours (70 degrees). Now it is ready for the Roof Mate Top Coat!

    great product
    Love the product, learning to hate the delivery system. 2 days late, handle removed to fit in box. How do you safely handle a 5 gal bucket of roofing material( extremly HEAVY) without a handle?

        Great product there is prep work that has to be done. And this product does have a top coat as well. Used it on my trailer roof and very noticeable difference in the heat difference.

        Most excellent product
        With a 20 year old RV TPO covering, this worked great. I did cover twice, just to be sure, as the previous owner had let it go. Henry's peeled right off, and I had washed the roof. This stuff was bullet proof, almost.
