I have no idea what a 2 step installation is, but when applying DOW you need to measure out the amount of "bite" on the frame and window and then tape that distance away. You will have tape on the frame and glass. If youve done it right, and used blue tape, it should look like a mexican...
When using caulk (Dow995) on a window for the 2 step installation... what side is best for giving it a gasket look? Top and Bottom? or the sides? We usually tape the sides first then come back the next day and tap the top and bottom... Is this correct or does someone have a better method?
