BestLatex R114

BestLatex R114 is used in the following applications:

• Bonding slurry coat (for waterproofing or bonding old-to-new concrete).

• Thin patching/repair mortar for surface finishing.

• Waterproof rendering mortar.

• Abrasion-resistant floor screed.

• Concrete repair mortar.

• Abrasion-resistant topping.

• Tile adhesive mortar.

• Waterproof masonry and plastering mortar.

• Excellent bonding and adhesion.

• Greatly reduces volumetric shrinkage during cement curing.

• Increases the flexibility and elasticity of cement-sand mortar.

• Maximizes waterproofing for surfaces frequently in contact with water.

• Increases resistance to chemical corrosion and mechanical abrasion.

• Chemically and physically stable. BestLatex R114 is a non-reversible polymer emulsion system; after application, it develops a film bonding network with silicate-based surfaces it contacts, so it does not revert to its previous emulsion form, even in highly alkaline environments.

• Non-toxic once cured, so it can be used for waterproof mortars in direct contact with domestic water.

• Increases the strength of floor rendering layers.

• Suitable for making patching and repair mortar where a thin finishing layer is needed.

Surface preparation:

• The concrete surface must be clean, hard and solid, and cleaned of oil, grease, dust, moss/mold, excess cement and other impurities, etc.

• If the surface has low roughness, it must be roughened by suitable mechanical means before applying the product.

• Saturate the entire surface with clean water, but do not leave standing puddles on the surface.

Waterproof bonding slurry or old-to-new concrete bonding coat:

• Mixing ratio: 01 liter BestLatex R114 + 01 liter water + 04 kg cement = 3.3 liters of bonding slurry.

• Application: Add the cement into the pre-measured BestLatex R114 and water mixture and stir until homogeneous. Apply the bonding slurry at a thickness of 1 - 2 mm onto the pre-saturated surface, then place new concrete or apply the waterproof mortar while the cement-BestLatex R114 slurry is still wet.

Waterproof rendering mortar:

• Mixing ratio: 01 liter BestLatex R114 + 03 liters water + 6.5 kg cement + 19.5 kg sand = 30 kg of mortar.

• Application: Using a trowel or steel float, firmly apply a mortar layer 1 ÷ 2 cm thick (as required) onto the freshly applied (still wet) waterproof bonding slurry. If the bonding slurry has dried, re-apply it before applying the waterproof rendering mortar.

Notes:

• BestLatex R114 must always be used together with cement; it should not be used alone as a standalone bonding and waterproofing agent. The sand used must be clean, free of impurities or mud and have a suitable particle-size distribution. The cement must not be lumpy or past its shelf life.

Cleaning:

• Clean equipment and tools with clean water after application and before the material cures.

Safety guidance:

• The product may cause irritation to sensitive skin on prolonged contact. Wear a mask, gloves and safety goggles when using the product.

• If splashed into the eyes, nose or mouth, rinse immediately with plenty of clean water several times before going to the nearest medical facility for timely and proper treatment.

• Avoid letting the product contact food or household items. Keep out of reach of children. Dispose of excess product at locations designated by local regulations.
