I would like to use this sealer on my grouted counter-top tiles.

Question 13

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.

Question 39

The wall-to-wall carpet and padding in our lower-level living area developed a musty smell shortly after receiving six inches of rain within two hours. The carpet and pad were removed and discarded. The base floor is untreated concrete slab and we found no visual sign of mold, mildew or water entry on concrete slab or carpet/pad. Cleaning the floor with soap and water and running multiple dehumidifiers for 2 weeks eliminated the odor. We then applied Concrobium mold control (to be safe). We'd like to seal the concrete to prevent moisture vapor from migrating through the concrete in the future. The folks at AFM recommended using MexeSeal for this purpose. As you carry both MexeSeal and Green Building Supply Sealer. Which product do we use? View answer
