Surface Preparation:
• For repairs, clean the surface with wire brush to remove hidden loose particles, sand, dust. Degrease the surface using suitable solvents.
• Remove the concrete portion by saw cutting, the extreme edges of the repair location at least to depth of 10mm to provide a strong bond.
• Clean the concrete surface to remove any contamination where breaking is not possible. Roughen the surface by light scrabbling.
• For priming of the concrete substrate, saturate the surface with potable water. Remove excess water prior to application.
For repair mortar
• Prepare the repair mortar with the following ratio - 50 kg Portland cement : 150 kg washed sand: 6-7.5 kg of Aquatech Waterproof Repair Polymer : 10 lit water
As a waterproofing coat
• Mix Aquatech Waterproof Repair Polymer with the cement in the ratio 1: 1.5 by weight.
• Mix for 2-3 mins to avoid air entrapment, add cement to Aquatech Waterproof Repair Polymer till a good consistency is achieved.
• Brush apply 2 coats on the concrete in a span of 4-6 hours. This can be used in areas like below the tiling areas in bathroom or sunken areas, small balconies, chajjas and parapet walls.
• Overlay with protective screed for the desired slope and thickness.
As a Bond Coat
• Mix Aquatech Waterproof Repair Polymer with Cement in the ratio of 1:1 by weight.
• Add cement into the additive and then stir slowly till homogeneity is achieved.
• Apply 1 coat to the prepared concrete substrate.
• Overlay with repair mortar when the bond coat is still wet/tacky.
As a Concrete repair and Floor screeds
• Use the below mentioned ratio for preparing repair mortars for concrete beams, columns, chajjas,
parapet walls
• Portland cement: 50 kg, Washed sand: 75 kg, 6mm Aggregates: 75 kg, Aquatech Waterproof Repair
Polymer - 6-7.5 kg, Water 10 lit
As a putty additive
• For 1 kg putty add 100 grms of Aquatech Waterproof Repair Polymer. Add water to achieve the desired consistency.
Curing and Maturation
• The standard maturation practices for concrete columns, beams, chajjas and parapet walls needs to be maintained even while using the additive.
• For waterproofing of low areas like below the bathroom tiles, or sunken areas, it is essential to provide 1-2 days of setting time for a proper solution.
General Instruction
• Use a mechanized mixer to ensure homogenous mixing of Aquatech Waterproof Repair Polymer with the remaining components. Hand mixing is permitted only for 25 kg or less.
• Add Aquatech Waterproof Repair Polymer to the batching/gauging water as per the dosage. Complete the addition of remaining water till desired consistency is achieved. Do not add water above the required quantity.
