BEEST Multi-Purpose Primer - Gray, 1 Gallon Covers up to 250 Sq Ft| Liquid Rubber Deck Coating - Elastomeric Roof Coating - Water-Based, High-Adhesion Bonding Primer for Concrete, Metal, Wood, TPO

Very good product! I own a 27' FR Lexington GTS and nothing eas wrong eith the roof but wanted to add some protection and additional insulation against heat in New Mexico! It took 2 days (8hr each day total to complete), with all the prepping, cleaning and sealing down satellite and roof windows using and adhesive roof sealing on the edges first. My RV has an edge about 1/2 so this thick coating doesn't run down and was very easy to apply. I used 4 gallons. Maybe 2 to 3mm thickness. Today 100F outside. Have 2 14,000 BTU A/C system going, one on the roof and one inside wenting through the window and it's a balmy 72F. BEFORE - it was 83F with 2 A/C going. The temperature difference inside is clearly noticeable even without running the A/C. I highly recommend this product. Make sure you clean the roof, prime it and apply thick coat and use roller and thick brush. I bought the 5 gallon bundle package. We'll see how long it holds up. The manufacturer says 15 year warranty. If last 5 years it was worth it.

1 gallon of primer covered approx 240 sq ft of roof without issue. I had a concern/question after receiving the primer and contacted Beest USA. Anne was the customer service rep that reached back out to me. Outstanding customer service provided. Thank you, Anne. 5 gallons of RV roof coating (non-silicone). I applied two coats on approx 240 sq ft of RV roof. This product states 5 gallons will cover up to 250 sq ft when applied on 2 separate coats. I probably have an easy 1.5 gallons left. I think the first coat I placed was a little thinner than it needed to be. The second coat was probably the right thickness. I should have enough to put a thin 3rd coat in the near future. I'm very happy with the product and that it's a soap/water clean-up vs. having to use any kind of solvent. I would highly recommend if you are looking for a non-silicone product.

Excellent product. Just follow the simple directions .

Good product

Great

So I received my order damaged. The 1 gallon of primer broke open during delivery. I contacted the company (BEESTUSA) via text and within minutes got a response. I spoke with Anne in costumer service and they are sending me a new one in 3-5 days. No hassle, just great customer service.

Worked great

We have used this primer multiple times and have had no issues with it. Works as it should. An application is easy with a roller.

Requires a lot of preparation. You need to remove all silastic before applying, not easy. But it does work.
