Has anyone discovered the best tool for cutting thicker (1 in. plus) extruded foam. An electric saw would produce a lot of harmful dust.
I've run into the same dilemna as "gonegolfin" post 107456.1 -DIY spray foam. Rear wall flange of bathtub was 3 inches outside the wall and just simply tiled over, by whoever originally installed it (70 year old house). Tiles, grout, etc. predictably failed. Didn't discover it till I was in the basement while a teenage daughter showered and it was raining in the basement ! Have stripped out everything to the studs - wet insulation, black mold - horrible !
I'm now trying to decide whether to hire a foam contractor, or follow some of the suggestions to gongolfin, re., use great stuff to glue in XPS foam.
I have 2 products gathering dust in the basement; 1 in. dow blue xps and 2 inch Homasote R plus with foil on both faces. Anyone have an educated opinion on which to use (or not) ? Thanks
