Material and labour for Water proofing treatment to sunken floors of kitchen, toilets, laboratories, bath and WC's etc shall be as under :- (a) Application of Two component Acrylic modified cementitious coating (i) The surfaces to be applied shall be completely dry and free from containments such as dirt, dust, oil, surface treatments and old coatings. Concrete substrates must be mechanically prepared using abrasive blast cleaning or milling to remove cement laitance, existing coatings and achieve a gripping profile that is clean, dry and free from laitance and any other form of surface contamination. The installation instructions in manufacturer’s published literature should be strictly complied with, including but not limited to the following :- (ii) Chipping out any visible cracks in “V-Groove” pattern as applicable. Special attention on this part. Cleaning of cracks & then filling those cracks with SIKA latex SBR 100 putty/ Dr Fixit 302 SBR latex / Perma latex SBR / FOSROC Nitabond SBR latex / Asian Paints latex as required. Final cleaning of surface with power grinder, wire brush, hair brush & vacuum pressure if required. (iii) Dampen all surfaces immediately ahead of application of Acrylic modified Cementitious coating of Sika Top Seal – 107 / Brush Bond FOSROC/ Dr Fixit/ STP/CICO. (iv) Whilst the surface is still damp from saturation (S.S.D), apply one coat of Acrylic modified Cementitious coating of Sika Top Seal – 107 / Brush Bond FOSROC/ Dr Fixit/ STP/CICO of viscosity as per manufacturer’s instructions. (v) Apply Glass Fabric Sheet of Sika Fab 1 / FOSROC/ Dr Fixit/ STP whilst the first coat is wet. (vi) Once touch dry, apply second coat of Acrylic modified Cementitious coating of Sika Top Seal – 107 / Brush Bond FOSROC/ Dr Fixit/ STP/CICO of viscosity as per manufacturer’s instructions on the entire area. (vii) Second coat shall be applied after 6-8 Hrs of application of previous coat and in the direction right angle to the previous coat.
