Rated 4.4 out of 5★by 10reviewers.
Rated 5 out of 5★by Works great on motorhome with rubber roof I used a primer coat over my rubber roof on my motorhome, then used a roller and brush to spread this over the entire roof. I can't tell you how happy I have been with this product. I did this a year ago....it is parked outside year-round and it still looks great.I figure I saved myself over a thousand dollars by doing this myself.I learned about it on an rv forum. Others have had success similar to mine. 05/22/2013
Rated 4 out of 5★by Works Well I have used this product on metal and rubber roofs and it works well. Easy to apply with brush or roller, although I prefer brush for thicker coat. I use 1.5 gallons on a 40x12 roof. Roof should be power washed and scraped of loose material. Although it says it's guaranteed for several years, I apply it every two- three years to minimize the chance of developing a leak.Well worth the price compared to RV supply stores. 04/12/2013
Rated 5 out of 5★by Wanted to seal aluminum roof on Toyota RV I began my prep with a simple washing and sweeping of the RV roof. It had been patched and repaired with at least 3 other products in the past including what looked like good ole fashioned tar. I had minor surface cracks and some peeling of those older products. I removed the loose materials. The Kool Seal was rolled on and detailed with a brush. The first coat was thin, and appeared inadequate to seal the cracks. I let that coat dry about an hour and reapplied a second coat. This stuff goes on like thin caulk and sealed nicely with the second coat. The total product used was just over 1/2 of the gallon can which gave some for reapplication at a later time. I delayed reviewing this product until it had been tested in the rain. Two rain storms, no leaks. I will keep an eye on the roof for developing issues but for $22.00 and about 2 hours time, I am very happy. 06/18/2014
Rated 5 out of 5★by Kool Seal I built a kennel for my puppy then put a tin roof on it. Was very hot inside until I painted the roof with Kool Seal. Now I sit in it with her while she's playing. Good stuff. 06/26/2013
Rated 5 out of 5★by Bonham, Tx Store - Won't keep it stocked Bought the last "Gallon" they had aprox 2 months ago. Need another, and they STILL don't have any in stock. It's listed as "IN STORE" only, so I can't even buy it with "Ship to Store" as an option. Guess, It's off to Lowe's or Home Depot...... Bummer! But if your store happens to be on top of it's inventory, it's a great deal, and works well. If you mix "Micro Balloons" which is a very fine hollow ceramic powder you will gain a lot of insulation and sound barrier benefits. Note, if you do mix in the micro balloons, you will have to add water to thin it back out, and you can only roll the end product on your project from that point. It will however end up making aprox 2 gallons of material. 11/10/2013
Rated 1 out of 5★by Wrong Product Fo RV Although reviews stated that this product was compatible with RV roofs, the directions on the container specifically stated "not to be used on rubber roofs". Description needs to be more specific. 08/02/2014
Rated 5 out of 5★by This was a great find. The price was the best This was a great find. The price was the best I’ve found.It does exactly what I was looking for it to do. 11/05/2013
Rated 4 out of 5★by Easy to apply I used Kool Seal White Elastomeric Roof Coating to cover weather exposed CDX Paneling. Now CDX in itself is an exterior panel material, but NOT if it is directly exposed to the elements, (rain, snow, ice, sun, humidity, etc., etc.). My project is an 8 x 8 "lean to" for my lawn tractor. I applied Kool Seal to one surface and the all the ends. The CDX really sucked up the sealant. I only bought (1) gallon, so I was only able to apply (3) coats. Very easy application with a roller for my project. The consistency was twice as thick as a good regular exterior paint, and cost less. I applied Kool Seal several days ago and it has rained several times since. I would say at this point My CDX panel is NOT going to make it. Moisture is still seeping into the ends of the paneling even with several coats of Kool Seal. I can see the CDX panel beginning to swell. With that being said, I still think that Kool Seal is a good product if used for the correct applications listed on the can. 09/02/2014
