Dr Fixit Tankpro W

Product Details

Dr. Fixit TankPro W is a two-component, solvent-free, thixotropic coating, based on high quality elastomeric polyurethane resins. After polymerization, it produces a strong, elastic, hydrophobic membrane suitable for waterproofing and protection of water tanks. Areas of Application Waterproofing and protection of: } Water tanks made of reinforced cement concrete (RCC). } Prefabricated concrete tanks. Features and Benefits } Excellent adhesion on RCC surface. } Being solvent-less, it can easily be applied in closed spaces. } Extremely hydrophobic and hydrolysis resistant. } Certified for potable water tanks, in accordance with the US FDA 175.300 requirements. } Single coating for Waterproofing and Protection for water tanks giving faster turaround time. Method of Application 1 GENERAL SURFACE PREPARATION: } Surface needs to be made clean, dry and sound, free of any contamination by wire brushing, which may affect the adhesion of the membrane to the substrate. Substrate concrete compressive strength should be cured for 28 days and achieve minimum 20 MPa compressive strength. Wash the concrete substrate with water pressure jet to remove all loose particles and dust. } Ensure the substrate has properly cured and the concrete is profile free, no ridges or troughs. All contaminants should be removed by mechanical vacuum assisted preparation equipment such as scrabbling/shot blasting/ diamond grinding to achieve a light abrasive blast to achieve preferred surface profile of CSP 4 or CSP 5. } If concrete surface found to be defective with pinholes/bug roles/honeycombs etc., it must be filled/ repaired using scratch coat prepare by mixing Dr. Fixit Superseal P200 WB and Dr. Fixit Superseal P100 aggregates in 1:1 ratio. Apply the scratch coat by using suitable spatula/squeeze to get level surface for the upcoming primer. 2 REPAIR OF CRACKS AND CONSTRUCTION JOINTS: } Existing surface cracks which are more than 1 mm and construction joints should be cut open in square or V -groove manner up to 10 mm width by using mechanical cutter. } Clean the groove with air blower to remove dust, dirt etc. primmed the groove with Dr. Fixit Pidiprime A and allow it to dry for 2-3 hours. } Slide the Feviseal PU/Hybrid Sealant into the applicator gun; extrude the sealant into the cracks ensuring that no air is trapped inside. } The treated cracks require minimum 6 hours to set and allowed to cure completely for a day. (Self-curing according to the room temperature). 3 CORNER TREATMENT – WALL TO FLOOR AND WALL TO WALL JOINT: } Moisten the surface with water & apply a bonding coat of Dr. Fixit Pidicrete URP and cement (1:1) by volume on cleaned RCC surface. Place angle fillet / coving by using Polymer modified mortar prepare with 1 kg Dr. Fixit Pidicrete URP, 5 kg fresh cement, and 15 kg graded quartz sand. (i.e., in the ratio of 1:5:15) on all along the joint RCC surface (slab and wall junction) and smooth finish. } Alternatively, V" grooves shall be cut along the wall & slab joints or construction joints for 10 x 10 mm using a hand cutter. } After cleaning the groove thoroughly, apply one coat of Dr. Fixit Pidiprime A primer and fill the gap with Feviseal Dr. Fixit TankPro W P
