Well after a bunch of reasearch, and shopping trying to find 3m5200 i found an alternative that is much cheaper and easier to find, especially for us canadians. I usually buy 3m 5200 from lows when i go down to the US but trying to find the fast cure is nearly impossible here in canada so i looked at the composition of it and found an exact match, PL POLYURETHANE CONRETE CRACH & MASONERY SEALANT. The only difference is the colour (light Gray). It does not bubble of expand like pl premium and it cures fleixble unlike pl premium. here is a link to a bit more info.
