Tapcon..about ready to jump out of a window
I'm using Tapcon to take up the bounce in my subfloor (over Delta-FL...see other post). The Delta-FL instructions call for 1/4" tapcon. If I do those, the heads are so big that I can't countersink it into the wood subfloor. I wonder if I'm not getting the whole cleaned out enough. Do you blow the hole out (not sure I could suck out thru the plywood and delta-fl)?
I tried 3/16" screw with smaller heads, but these break almost every hole as I'm just about at the end of tightening.
