We are in the process of having our basement finished (woo hoo, I am not doing it, boo hoo, it is $$$$).. We are looking at ceiling tiles. Contractor recommended the Armstrong Sahara (271). Though it is nice, we are looking for something with a smoother finish. The Sahara has quite the abrasive finish. Anyone have ideas for a smooth panel with the "drop-in" feature of the 271?

The corner of my poured basement concrete walls had a hairline crack that I sealed using a polyurethane injection kit. This has worked well so far but I see efflorescence buildup through on one area of the patch - indicating water leakage. Should I remove the epoxy sealant and re-inject foam again ? I have also noticed minor seepage on another hairline crack that I plan to fix using polyurethane Main question : Is there anyway to ensure that this problem does not re-occur and prevent further leaks using a product (or combination of products) like - Penetrating concrete sealers (Lithi tek 9500, radon seal etc) [url=http://www.homedepot.com/p/Ghostshield-1-gal-Invisible-Penetrating-Concrete-Sealer-Waterproofer-Plus-Densifier-9500/205212663]Ghostshield 1 gal.
