Latex Plus

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

Application Areas

	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.

	Usability – Easy to use, non-toxic, economical.

	Abrasion Resistance – Improves abrasion resistance by increasing the hardness of the cured concrete.

	Compressive Strength – Exhibits good compressive strength for heavy traffic applications.

	Weather Resistance – Can be used as frost resistant render.

	Bonding – Shows good bonding with concrete, brick & stonework, plaster & cementitious surfaces cured asphalt substrates etc.

	Crack resistance – Prevents cracking by improving flexural strength. Reduces aging & drying shrinkage cracks.

	Corrosion & Erosion – Improves erosion helps to reduce corrosion & hence provides durability.

	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.

	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

	For priming of exposed rebars, mix 1 part Latex Plus with (2.5–3) parts of fresh cement & apply on the substrate.

	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.

Wide range of mix designs are recommended for various application purpose using Latex Plus. The mix designs are as follows:

	Heavy Duty Floor Screed	Patching Repair Mortar	Renders	Bonding Mortars for bricks & Tiles
Consistency	Semi‐dry cohesive consistency	Mortar Consistency
Thickness (mm)	10 to 40	6 to 40	6 to 9	6 to 40
Latex Plus	10 litres	10 litres	10 litres	10 litres
Water	6 litres	10 litres	6 litres	7 litres
OPC	50 kgs	50 kgs	50 kgs	50 kgs
Sand	75 kgs	150 kgs	150 kgs	150 kgs
3-5 Aggregates	75 kgs

	Do not dilute beyond recommendation

	To be applied over damp substrate but in a tack free condition

	Waterproof coats with Latex Plus must be protected with plasters/screeds

	Not recommended for use in very critical concrete repairs

	While applying as a bond coat, if it becomes dry, re-apply to reach a tacky state for overlaying of concrete/mortar

	Recommended dosage to be followed to attain desired results.

	Avoid prolonged skin contact

	Cementitious mortars & slurries mixed with Latex Plus, may release alkali – which can be harmful to skin & eye. Hence, necessary precautions should be taken along with respiratory protective equipment

	Avoid contact with foodstuff & utensils

	In case of eye/mouth contamination, wash thoroughly with plenty of clean water immediately & seek medical advice

	Keep out of childrens’ reach.
