Latex Plus

SBR based polymer for repair & waterproofing Latex Plus is Styrene-Butadiene Latex based liquid for waterproofing & multi-purpose repair work.

Areas of Application

  • Waterproofing – Balconies & staircase, bathrooms, terraces & lift pits, tanks for liquids, decks, walkways, chajjas etc.
  • Bond coating – New concrete to old concrete, plastering, masonry stone work
  • Concrete repairs – Spalled concrete of floors, columns, slabs, chajjas, beams, parapets etc.
  • Cladding – Horizontal fixing or re-fixing of stones & marble bedding, tiles, slip bricks etc.
  • External rendering
  • Bonding Agent – Bonding mortar for tiles & panels.

Method of Application

Surface Preparation

  • Surface to be treated must be thoroughly cleaned from all kind of laitance, oils, grease etc.
  • Mechanical means such as shot blasting, wire brushing can be used followed by vacuum cleaning of all loos materials. Degrease the surface by using suitable solvents
  • Repair the spalled concrete section by saw, cutting the extrem edges of the repairable portion – at least to a depth of 10 mm to avoid featheredging & to afford better bonding
  • Roughe the surface by light scrabbling or grit blasting
  • Expose corroded rebar in the repairing area totally. Remove all loose scale & depositions followed by immediate cleaning.

Priming

  • For priming of concrete substrate, the surface should be thoroughly washed with clean water
  • Remove excess water. Make sure that the surface is damp but touch dry – before application
  • Prepare the ‘primer coat’ by mixing 1 part Latex Plus with 3 parts of fresh cement. Slowly mix cement with Latex Plus to obtain a smooth consistency. Continue mixing the slurry during application to prevent settlement
  • Cladding – Horizontal fixing or re-fixing of stones & marble bedding, tiles, slip bricks etc.
  • For priming of exposed rebars, mix 1 part Latex Plus with (2.5–3) parts of fresh cement & apply on the substrate.

Preparation of Mortar

  • Hand mixing is permissible only for 20 Kgs of the total mix weight or less quantity
  • A forced action PAN mixer is recommended to prepare a homogeneous mortar mix with Latex Plus. Use a suitable sized drum with heavy duty electrical drill machine fitted with spiral paddle mixer at a speed of 400–500 rpm
  • Charge the mixer with required quantity of clean, dry sand, cement & mix for 2 minutes. Mix recommended dosage of Latex Plus with half of the gauging water & add to the sand-cement mix. Mix for another 3-4 minutes to avoid air entrapment. Keep on slowly adding the rest of water until the required consistency is obtained. Don’t add extra water.

Packs Available 500 g., 1 Kg., 5 Kgs., 20 Kgs.

Coverage Approx. 20 – 22 ft2/kg for 2 coats (Latex Plus + OPC in ratio of 1 : 1.5).
