Question 31

I have an underground storage tank (kerosene) that had 2 copper pipes which were terminated and covered with cement and some type of epoxy patch. The patch failed after 13+ years (we bought home not knowing about the tank) - had the cement removed enough to see only one of the two copper pipes was crimped - the other one had a sliw frp - that has been crimped and epoxy applied but basement still smells of kerosene. Does your dynaseal product seal cement so we won't smell kerosene? View answer

In my upcoming home re-roofing job, my roofer is going to be sealing any soffits or vents that are up on my roof while it is re-tiled.I am looking to use a ceramic lightweight S tile which will have an underlayment below the tile. My roof job will entail sealing the installation of these vents onto the roof, and then I would have the underlayment abut or overlap slightly.

I would like to use AFM Safecoat Dynoflex textured natural ? View answer
