Liquid Rubber Waterproofing and Protective Coating - Roll On (1 Gallon EXTRA STRENGTH, Dark Gray)

TL;DR: Great stuff I put on our camper roof to waterproof and seal. Seems to work at a great price.I came on Amazon looking for FlexSeal or the Rust Oleum LeakSeal and stumbled upon this stuff with incredibly high reviews.Pricing and Packaging: I got one gallon of white and the price is pretty good when put up head-to-head with the competition. Product showed up padded inside a box inside another Amazon box.Application: I used it on a 1994 19' Starcraft camper trailer that had never been completely sealed. We bought it last year and the previous owner had a small leak spring in the back years prior that he had sealed up. The roof had been heavily caulked around all the vents and seams, but the rest of the roof had never been touched. I applied two coats of the RubberSeal--the first with a paintbrush so I could get it on thick and the second 24 hours later with a 6" mini roller from Walmart. I applied mine inside the garage, but I would wait for a few days of sun before I put it on. I also didn't bother cleaning the roof, although mine was surprisingly clean already.Results: One coat of RubberSeal didn't do a great job of covering the roof. The second coat covered it well enough that it should be fine. This only used half of my gallon jug, so I will probably roll a third coat on just for giggles. The sealant got down into all the cracks and seams of the roof and along where the metal meets the vents and just sealed right over it all. It seems like it had a good bond--I can't scratch or chip it off with my nails.Cleanup: I just tossed my paintbrush and roller cover, but it says to use mineral spirits or baby oil, which I had neither of on hand. Gasoline and paint thinner were both a no-go. Didn't touch the stuff.If I don't update this review, assume that I am 100% satisfied with the product and recommend it to all RV'ers!

THE MOST IMPORTANT PART OF THE JOB !! but after a few coats , cleaning gets easier 🙄Learned years ago prep is always the most important part of any job. CLEAN and things will always turn out much better ✔️😁

I haven't had it on what I used it on long enough to know how well it lasts. But I used it on a worn out tarp I have over my leaking aluminum shed. The sun had dried it out and it started leaking. I rolled this rubber seal over the tarp and it stopped it from leaking. 2 coats to be sure. I got another bucket of it for later. Cheap easy way to protect my shed. They all start leaking after few years. Mine was accelerated by some kid getting on top of it and well, you can guess the rest.

Fast shipped, accurate shipment delivery tracking status updates, high quality item, I recommend both the seller and this product

Fabulous stuff! Used to repair a big crack in shower floor. Sanded it a bit; put the recommended fiber 'paper' on the cracked area; did three coats to give a good thick coat.....waited between coats a few days (have another shower to use) and then when put the final coat on, let it 'cure' to harden it up, as Dan from the company suggested. It looks great!! Will take a picture and post soon. The project was done by our helpful neighbor who had fixed fiberglass shower floor before. He started out doubtful it would work, but by the end of the project he became a 'convert'. Really great stuff. I am thinking of painting our other shower floor just to make it so clean and white again, even though it is not cracked. I am looking for things to rubberize around our place now.

I have used 2 gal. on cargo trailer roof. I used 3m 5200 along with screws to seal the 1/4 in. Plywood to the trailer frame work . I have used 2 gal. to cover aprox 105 Sq. Ft. I allowed it to flash off between coats. 7 coats using a short nap roller. Application was easy. I will update if any issues arise. It appears that this product will spot repair fairly easily if needed in the future. My only regret is not using marine grade Plywood as the glue is the same but I had issues with voids in the lamination of the "CD" grade Plywood. Note : I also used polyester resin with fibreglass tape to join the Plywood sheeting at the 4ft. seams making the joints at the roof ribbing.Looks good at this time. I only want to do this once! Definitely better than the garbage sheet metal that the manufacturer used.

This stuff is great. We had leaks on our flat build-up roof. The cost to replace the roof was exponential, so we decided to try this sealant out.You can layer it as thick as you want, but be sure to follow the instructions exactly or you might encounter leaks.We also used it to seal over all of the screw heads on our metal roofed patio awning.I recommend it!
