65 sf residential new construction master bedroom deck over "Torch On" roofing sheets. Pressure washed roofing membrane clean. Allowed to dry, then prepped with 3 pails of TR 400 to even out roofing membrane overlaps.
Then installation of the 1" thick 12" x 12" Natural Stone Pavers with 3 more Units of TR 400. Originally estimated 2 units of TR for installation, but needed 1 more for additional back buttering to make up for some slab irregularities as we got closer to the structure.
Used 1/4" x 1/4" x 1/4"trowel. Back of paver was reasonably flat. Sealer was very helpful for clean up of TR 400 smudges with Uzin clean box. Then sealed again after grouting. Nice install over Torch on for this high end home.
