Notify Architect in writing of anticipated problems using waterproofing over substrate. 4. Proceed with installation only after unsatisfactory conditions have been corrected. 3.2 SURFACE PREPARATION A. Clean, prepare, and treat substrates according to manufacturer's written instructions. Provide clean, dust-free, and dry substrates for waterproofing application. B. Mask off adjoining surfaces not receiving waterproofing to prevent spillage and overspray affecting other construction. C. Remove grease, oil, bitumen, form-release agents, paints, curing compounds, and other penetrating contaminants or film-forming coatings from concrete. D. Remove fins, ridges, mortar, and other projections and fill honeycomb, aggregate pockets, holes, and other voids. E. Prepare, fill, prime, and treat joints and cracks in substrates. Remove dust and dirt from joints and cracks according to ASTM D 4258. F. Prepare, treat, and seal vertical and horizontal surfaces at terminations and penetrations through waterproofing and at drains and protrusions. 3.3 FULLY ADHERED SHEET INSTALLATION A. Install fully adhered sheets over entire area to receive neoprene sheet flashing according to manufacturer's written instructions and recommendations in ASTM D 5843. B. Apply bonding adhesive to substrates at a rate of one gallon per 125 square feet and allow to partially dry to the touch. The bonding adhesive should be tacky, but no adhesive should transfer to the finger when pressed into it. C. Remove poly film from neoprene sheet and cut roll to workable lengths for the application of the bonding adhesive. B. Apply bonding adhesive to neoprene sheet flashing and firmly adhere sheets to substrates. Start application of neoprene sheet flashing by placing it 4” onto horizontal deck, extend sheet across 2” structural expansion joint and extend it up 6” onto vertical substrate. Accurately align sheets and maintain uniform end lap of 6” minimum. Install termination bar & sealant at the top of the neoprene sheet flashing in accordance with manufacturer’s recommendations. C. Repair tears, voids, and lapped seams in waterproofing not complying with requirements. Slit and flatten fish mouths and blisters. Patch with neoprene sheet flashing extending beyond repaired areas in all directions. D. Protection: Protect building from damage resulting from spillage and dropping materials. Do not allow materials to enter and clog drains and associated piping.
