ShaliSBR Latex

Surface Preparation

• Remove all loose concrete, grease, mould oil or curing compound from concrete and steel surfaces using wire brush, scrubber.
• Saw cut the concrete areas to a square or rectangular profile to a minimum 10 mm depth at the extreme edges.
• Treat surface with 5% – 10% hydrochloric acid, followed by complete neutralization with water, which will improve bonding of the coating. Oils, greases & mould release agents can be cleaned with solvents.
• Remove excess / standing water.

As Bonding Coat / Primer

• Mix 2-parts cement to 1-part ShaliSBR Latex by weight of cement.
• Mix to a lump free creamy consistency for 2-3 minutes by slowly adding ShaliSBR Latex.
• Using a stiff brush, apply the bonding slurry well into the damp surface, when the bond coat is tacky, apply mortar / screed overlay.

As Waterproofing Slurry

• Repair all cracks in the prepared surface thoroughly with PlastiSeal.
• Prior to application of waterproofing slurry, damp the surface to be coated by sprinkling water. Avoid formation of puddles of water.
• Mix 3-parts cement to 1-part ShaliSBR Latex by weight of cement with suitable addition of water.
• Mix to a lump free creamy consistency for 2 – 3 minutes by slowly adding ShaliSBR Latex.
• Using a stiff brush, apply the bonding slurry well into the damp surface.
• After the first coat has dried, apply second coat at right angle to the first followed by mortar/ screed overlay. Average time gap between two coats is 3 to 5 hours.
• Apply second coat and allow it to air cure for at least 72 hrs.
• Protect the coating with a cement screed overlay at least 25 mm thick.

As Repair Mortar

• Mix Design: 50 kg cement : 150 kg of sieved sand (Zone II) : 8 – 10 kg of ShaliSBR Latex: 10 – 12 L of water.
• Mixing Process: Mix sand and cement in Pan type mixer for 1 – 2 minutes. Hand mixing is only permissible when the total weight of the mix is less than 25 kg.
• Mix the required quantity of ShaliSBR Latex and water for 2 minutes in a separate container, to avoid excessive air entrapment.
• Finally add the liquid mix slowly into the mixer containing the mixed sand and cement until the required consistency is achieved.
• Apply repair mortar at a thickness of 10 – 20 mm or, when the bond coat is still tacky. Finish with trowel for smoothness.

Polymer Concrete and Screed

• Mix Design: 50 kg Cement : 75 kg of sieved sand (Zone II) : 150 kg 6 mm down size washed aggregate : 8 – 10 kg of ShaliSBR Latex : 12 – 15 L of water.
• Apply bonding coat by mixing ShaliSBR Latex and cement in 1 : 2 by weight and apply by brush a single coat over the prepared surface.
• The prepared mix placed over the wet bonding coat (tacky) and usually applied by trowel to 10 mm to 40 mm thickness well compacted and finished using wooden or steel trowel.
