Features & Benefits

WHERE TO USE

Mapesil LM is a low-modulus, solvent-free sealant, formulated for sealing all materials that are sensitive to acids and plasticizing agents, marble, granite, sandstone and quartz. Due to the chemical nature, which deters surface bleeding or the migration of plasticizing agents which would stain the surface.

The characteristics of the product also make it suitable for particularly delicate substrates, such as cellular concrete, brickwork and varnished or enamelled wood.

It is also ideal for contact with absorbent mineral surfaces such as concrete, renders and fibre-cement.

Performs well in treated water typically found in swimming pools.

Thanks to the elasticity of Mapesil LM, it is suitable for a number of sealing applications, such as:
– pre-fabricated panels;
– window/door fittings and wall surrounds;
– pipe-work and vertical walls;
– similar and/or different types of coating materials.

It is also suitable for sealing joints in floors with limited
pedestrian traffic.

TECHNICAL CHARACTERISTICS

Mapesil LM is a solvent-free, one-component, neutral-cure silicone sealant which does not emit unpleasant odours, available in the form of a thixotropic paste. The product will remain flexible from a temperature range of between -40°C and +150°C. Mapesil LM delays the formation of surface mould. Mapesil LM offers good resistance to chemical agents. However, because of the wide range of products and service conditions, if in doubt carry out preliminary tests beforehand.

Mapesil LM bonds perfectly to most types of substrate used in the building industry without applying a primer beforehand (glass, ceramic, marble, aluminium, zinc-plated sheet metal, concrete, stainless steel and PVC).

If in doubt, please contact the MAPEI Technical Services Department or carry out preliminary tests beforehand. Mapesil LM is suitable for substrates sensitive to acids, whereas conventional neutral or acid sealants normally provoke changes in colour or staining of the substrate.

RECOMMENDATIONS

• Do not apply Mapesil LM on heavily-plasticised plastics, rubber or bitumen. The oil and plasticising agents in the substrate may migrate to the surface and compromise the bond

• Do not use for sealing floors subject to intense traffic (use Mapeflex PU45, Mapeflex PU20 or Mapeflex PU21).

• When using on marble, do not use Primer FD

CURING

When Mapesil LM is exposed to the air, the surrounding humidity sets off the cure reaction and the sealant becomes flexible.

The surrounding temperature only has a small impact on the cure rate of Mapesil LM, while the level of humidity in the surrounding air has the most influence.

STORAGE

You are able to store cartridges for up to 18months in a dry, cool environment.
