Water Proofing Application
Apply by brush or roller a coat of Dr. Fixit Pidifin 2k a polymer modified cementitious seamless waterproofing membrane at a rate of 12-14 square meter per kg to all required areas, at a thickness of 500 – 600 microns and allow to dry for 4 -6 hours. Apply second coat in the opposite direction at the same rate. After application of second coat of Dr. Fixit Pidifin 2k it gives the total thickness of 1 to 1.2 mm. The treatment is left as it is for 72 hours for air cure before carrying out ponding test. Ponding test shall be carried out at a depth of 50mm to determine water tightness.
The waterproofing shall be carried at least 300 mm-on vertical surfaces, or at least 150mm above the floor finish level. The membrane shall be applied to the internals of the down pipes before laying of the tiles, bedding and floor traps. Upon successful completion of the ponding test, a layer of 10mm Cement/Sand (Ratio 1:4) protective screed, using Dr. Fixit Pidiproof LW Integral Waterproofing Compound @ 200ml/50 kg bag of cement, shall be applied on top of the membrane. Care shall be taken whilst laying the protective screed so as not to damage the waterproofing membrane below.The contractor shall take all measures necessary to prevent any damage to the membrane or protective screed during subsequent work. |
