Created a total mess, completely ruined our project - new awning cover is now trash for a landfill and the project cost has now doubled. I thought to myself when picking this up "NEVER buy DAP for anything ... eh, I don't want to go upstairs to get the better stuff, how bad could it be? It'll work fine..." And now I have reminded myself once again: NEVER EVER EVER BUY DAP PRODUCTS! THEY ARE HORRIBLE. I will despise you until my dying day, DAP!

DAP = "Don't Apply Period" It NEVER cured and now it's all over a brand new $25,000 deck. Calling them was no help. All I can do now is scrape and scrub and hope I don't destroy the deck or the house. This stuff is JUNK!
