Product Details

Mapei Latex Plus 215210

WHERE TO USE

• As an admixture for Keraquick to obtain a high performance, fast setting, highly deformable (class C2F S2 according to EN 12004) adhesive for ceramic tiles and stone material.

• As an admixture for Nivorapid and Planipatch to obtain an ultra-fast cementitious levelling compound with improved deformability and bonding strength.

TECHNICAL CHARACTERISTICS

Latex Plus is a water dispersion of an extremely flexible polymer with low viscosity to be mixed with Keraquick, Nivorapid and Planipatch in order to improve their deformability without otherwise changing their application and performance characteristics.

RECOMMENDATIONS

• Keraquick, Nivorapid and Planipatch mixed with Latex Plus should never be applied at temperatures below +5°C or above +30°C.

• Do not use more than the recommended amount of Latex Plus.

• Do not add Latex Plus or water to a mix that has already begun to set.

• Do not leave Latex Plus, Nivorapid, Planipatch and Keraquick exposed to direct sunlight for long periods of time before using.

APPLICATIONS

A) Latex Plus + Keraquick Fast setting adhesive with high deformability for interior and exterior installations of ceramic tiles and stone material. B) Latex Plus + Nivorapid or Planipatch Fast setting skimming compound with high deformability for interior surfaces.

A) LATEX PLUS + KERAQUICK WHERE TO USE

Interior and exterior installations of all types of ceramic tiles (double-fired, single-fired, gres, clinker, terracotta, vitreous mosaic, porcelain, etc.), including large sizes, and natural stones. Particularly recommended for installing all types of thin porcelain tile (both with or without glass fibre reinforcement mesh). Some application examples Installation of ceramic and stone material on: • underfloor heated installations;

• façades, balconies, terraces;

• precast concrete walls;

• existing floors (ceramic tiles, marble, PVC rubber, etc.);

• cement screeds or hot-poured asphalt substrates (provided they are stable and well oxidized);

• deformable surfaces (wood, metal, etc.).

APPLICATION PROCEDURE

Preparing the substrates Substrates must be flat, mechanically strong, free of loose parts, grease, oil, paint, wax, etc. and sufficiently dry. Damp substrates could slow the setting of Keraquick + Latex Plus. Cementitious substrates must not be subject to shrinkage once the tiles have been installed, therefore in warm weather renders should be cured at least 1 week per centimetre of thickness. Cementitious screeds must have an overall cure of at least 28 days unless they have been made with the special MAPEI binders for screeds such as Mapecem, Mapecem Pronto, Topcem or Topcem Pronto.

Cool surfaces that are too hot due to exposure to direct sunlight by dampening them with water.

Gypsum substrates and anhydrite screeds must be perfectly dry (maximum residual moisture 0.5%), sufficiently hard and free from dust. They must be treated with Primer G or Eco Prim T. Areas subject to high humidity must be primed with Primer S. In general, refer to the relevant MAPEI technical documentation regarding substrate preparation before repairing cracks in substrates, consolidating rapid-drying screeds and levelling installation surfaces.

Mixing ratios

Mix Keraquick with Latex Plus only, without adding water, when maximum deformability is required. The mixing ratios are as follows: – 8 to 8.5 kg of Latex Plus for each 25 kg bag of Keraquick grey; – 7.5 to 8 kg of Latex Plus for each 23 kg bag of Keraquick white.

Preparing the mix

Pour the powder into the liquid, mixing with an agitator at low speed until a homogenous, lump-free paste is obtained. Let the mix sit for a few minutes, then mix again briefly, and apply. Applying the mix Spread a thin layer of the mix down to a feather edge using the flat face of the trowel, then use a notched trowel to apply enough adhesive to guarantee sufficient wetting of the back of the tiles. Always be careful to stay within the open time of the adhesive. In certain ambient conditions (high temperatures, dry, windy weather) the open time may be shorter than usual. N.B. For exterior installations of large size tiles, floors to be polished in situ, or those subject to heavy traffic, back-buttering is recommended to ensure total transfer of the adhesive without voids.

GROUTING AND SEALING

Joints can be grouted after 2-3 hours with the special MAPEI cementitious or epoxy grouts, available in different colours.

SET TO LIGHT FOOT TRAFFIC

Floors are set to light foot traffic after 2-3 hours. READY FOR USE Surfaces are ready for use after 24 hours. Basins and swimming pools can be filled after 3 days.

CONSUMPTION

Latex Plus Keraquick

– Mosaics and small-sized tiles: 0.7-1 kg/m² 2-3 kg/m²

– Medium-sized tiles: 1.3-1.7 kg/m² 4-5 kg/m²

– Large-sized tiles: 2 kg/m² > 6 kg/m²

B) LATEX PLUS + NIVORAPID OR PLANIPATCH

WHERE TO USE

• Levelling of wood plank-on-edge flooring, chipboard, and plywood.

• Levelling of sheet metal, PVC, rubber, linoleum, strong non-woven flooring, and ceramic tile.

• Levelling for walls and floors on all substrates normally used in construction, provided they are not subject to the presence of moisture.

• Levelling of flexible and deformable substrates varying in thickness from 1 to 20 mm (Nivorapid + Latex Plus) or from 0 to 10 mm (Planipatch + Latex Plus), to ready them to receive any type of ceramic, resilient or textile flooring.

RECOMMENDATIONS

• Do not use externally.

• Do not use on substrates subject to rising damp.

• Do not use directly on anhydrite surfaces (treat first with a coat of Primer G or Eco Prim T).

• Do not use Nivorapid or Planipatch mixed with Latex Plus as a skimming compound underneath parquet or glued wood flooring.

• When used for resilients, watch out for imprintability. If possible, use Latex Plus diluted with water.

APPLICATION PROCEDURE

Preparing the substrate Substrates must be solid, free of dust, loose particles, paint, wax, oil, rust and gypsum residue. Nivorapid or Planipatch + Latex Plus form a levelling compound with excellent adhesion on metal surfaces, existing rubber floors, PVC, strong non-woven flooring, chipboard, parquet, linoleum or similar materials. These surfaces must be clean and sanded before levelling with Nivorapid or Planipatch + Latex Plus. Before applying, make sure that existing flooring is well fastened to the support. Nivorapid + Latex Plus and Planipatch + Latex Plus can be applied in thicknesses from 1 to 20 mm (Nivorapid + Latex Plus) and from 0 to 10 mm, even in a single coat, without cracking or crazing. Once they have hardened they are highly flexible with excellent adhesion to all supports, without needing the application of a primer, except in the cases mentionated above. Preparing the mix Nivorapid or Planipatch should be mixed only with Latex Plus, without adding water, when maximum deformability is required and for applications over difficult surfaces. Pour 6-9 kg (the exact quantity depending on the type of levelling compound to be made, that is on floor or wall, and on the viscosity desired) of Latex Plus into a clean receptacle and add a 25 kg bag of Nivorapid, preferably mixing with an agitator (at low speed) until a homogeneous, lump-free paste is obtained. When using Planipatch the amount of Latex Plus to be used varies from 5.75 to 9 kg of Latex Plus for each 25 kg bag of Planipatch. Mix only enough Nivorapid or Planipatch + Latex Plus at a time that can be used within 10-15 minutes at +23°C.

Applying the mix

Apply Nivorapid or Planipatch + Latex Plus with a metal trowel. When needed, several coats may be applied in rapid succession as soon as each coat has hardened (after approx. 50 to 60 minutes, depending on temperature and on the absorbency of the substrate). Flooring can be bonded to Nivorapid or Planipatch + Latex Plus skimming compound 12-24 hours after application, depending on the thickness, ambient temperature and humidity.

CONSUMPTION

Nivorapid + Latex Plus Nivorapid: 1.3-1.5 kg/m² per mm of thickness.

Latex Plus: 0.3-0.5 kg/m² per mm of thickness. Planipatch + Latex Plus Planipatch: 1.3-1.4 kg/m² per mm of thickness.

Latex Plus: 0.32-0.47 kg/m² per mm of thickness.

Cleaning Tools can be cleaned with plenty of water before the adhesive hardens. Afterwards cleaning is very difficult. Solvents, like mineral spirits, may be helpful.

PACKAGING

Latex Plus is available in 10 kg drums.

STORAGE

Stored normally, in original sealed packaging, Latex Plus is stable for 24 months. Protect from frost.
