Coating a TPO (vinyl) Roof
Our TT is 13 years old. The vinyl TPO roof is still in decent shape, even though it sits out in the Phoenix heat (mostly) year round. Lately I've been wondering what to do when the vinyl starts going ...
Forum Discussion
So here are the products I've heard about so far here and on other threads, and basic comments:
APPLIED BY PROS
Rhino Liner - Pricey, not great adhesion over non-metal & flexible surfaces (as reported by one person on another thread & others)
FlexArmor - Pricey, lasts 10-15 years & lifetime leak guarantee
Latex Elastomeric types DIY
Hengs - one source says OK over TPO, another says no. May need a recoat 3-4 years in desert
Elastomeric (Henry 287, 687, et. al.) - recoat every 4-5 years. Actually not recommended for RV roofs (but some have used it for that)!
Solvent Based DIY
Inland Coatings RC-2000 Found this on the web - ANYONE USED? (one person on another thread recommended this) Says good for TPO and all RV roofs and without primer. 15 year guarantee
Silicone (e.g., Henry's 887 Tropi-Cool) - ANYONE USED THIS ON AN RV? Henry says it's 887 can do RV roofs including TPO. I wonder how this is to walk on or to repair (will anything other than silicone stick to it for repairs, like Eternabond Tape). . .?
Superior RV Liquid Rubber - Good for TPO with no primer.
Someone in another thread recommended this product. Appears to be like Inland Coatings and perhaps also LiquidRoof. 15 year guarantee
LiquidRoof - must use primer over TPO (product also requires catalyst). Looks like about 5 year longevity before a recoat is probably needed. (Moderator Extraordinaire Barney gives a real nice report of applying this product in the 2nd thread linked here!)
