I have looked at allot of DIY background threads and there have been people that have used drylock but I believe they sealed it with an epoxy. I would really look into the Sikatop 107 it's a two part waterproof sealer, it is 100% nontoxic, safe in potable water sources and can be colored with cement dye. I contacted Nufish a member of a cichlid forum who used it on his DIY background and he has had in his tank for 8 years an it's still holding up with no fish loss. It can be a little expensive but worth it in the long run.
