I'll try to give the short version! I repaired a 2 ft. long crack in my 12
X 16 patio slab. I applied a sealant to the repaired area which dried much
darker than the original slab, which has a white, almost glossy appearance.
I scrubbed the repaired area with gas, dishwasher soap & hot water and got
about half of it off. Assuming I can get all of the sealer off, should I
use Thomson's Treatment as a sealer? I don't like Thomson's so I use the UV
Flood brand on my wood, but perhaps Thomson's is OK on concrete. If I can't
get the rest of the dark sealer removed, what would be the easiest way to
get a uniform color on this slab, which is only 3 years old and I won't be
replacing it soon! Thanks!
