Question 23

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

Question 33

Hi, I'm staining my concrete floors in my basement. I have fixed some small cracks w something called quick Crete. Then sanded them down, next I will stain. Is this an appropriate sealer given I am staining and repairing the concrete first? The concrete is fairly smooth, I would like the floor to be waterproof and to protect my floors while giving a nice light sheen. Is this the right product? If not what would you recommend? Thank you View answer

Question 34

Hi - I created a new birdbath out of concrete that has imprints of leaves on the inside. I want to seal the birdbath including the inside that will hold the water. Is there a sealer that I can use that will be non-toxic to birds? I understand that the PH will be high on fresh concrete and that there are products that can reduce the PH of the concrete before sealing it. Will that be necessary before using the sealer? Although the birdbath is large (~ 2 x 2.5 ft.) I believe that I don't need a full gallon of the product. Can I get it in smaller sizes? Thanks, Steve View answer

Question 36

I have an interior cement basement wall in a rec room that is starting to crumble in places because moisture is coming through. I used drylock 15 years ago and it worked great for years, but boy did it stink! It looks like I need to repeat the process now on a small area of the wall. What less awful product can I use to seal it this time? (It was painted over with Ben Moore latex paint so it does have paint on it) Or could I use drylock and then seal that in, but with what? Thanks in advance! View answer
