Customer Questions & Answers

can this be used over the old 204?

can this be used over the old 204?
Asked by: tak
Yes, you can. You will want to remove whatever old and loose product you can and follow the prep instructions on the label. If you want something a little more flexible that will last longer, then I recommend using one of our Rubberized Roof Cements. Our Henry 209XR Extreme Rubberized Wet Patch has the most rubber with UV inhibitors so it won't crack and offers a Lifetime year warranty; Our Henry 208R has the next most rubber and offers a 10 year warranty; and finally our Henry 208 Wet Patch is rubberized and offers a 7 year warranty. For more info, check out www.henry.com or contact our product support at 800-486-1278. Thanks for putting your trust in the Henry Company and Home Depot.

Anyway to thin this to use easier?

I am using on a plant box that is wood, its so thick I can barely get it on. Anyway to thin this out?
Asked by: George80
Heat makes it more workable. Leave it out in the sun for a while or place it near a heat source, but not open flame since its flammable.

0.90-Gal. 204 Plastic Roof Cement is rated 4.8 out of 5 by 4.
Rated 4 out of 5 by from It used to be so much better The old 204 was so much better. This new stuff is runny and it cracks once it dries, the old 204 wouldn't crack even after years of being exposed to the sun. Still it is much better than the other brands. Make sure you buy a pair of gloves with it because it will get all over the place, and its very hard to remove from your hand.
