Description

Solvent-free, odourless, non-staining, neutral cross-linking silicone sealant for natural stone, marble and agglomerate stone. Unsuitable for continuous water immersion. Coverage depends on the size of the tiles and joints.

Application

Thanks to the low modulus of elasticity of Mapesil LM, it is suitable for sealing internal and external fillet and expansion joints, including those subject to high levels of movement when in service, between:

• 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.

Uses

Mapesil LM is a solvent-free sealant with a low modulus of elasticity specifically formulated for sealing all materials sensitive to acids and plasticising agents, marble, granite, sandstone and quartz due to its chemical nature which deters surface bleeding or the migration of plasticising agents which would otherwise stain the substrate. The chemical characteristics of the product also make it perfectly suitable for particularly delicate materials such as bricks, cellular concrete and varnished or enamelled wood. Mapesil LM generally forms an excellent bond on non-absorbent substrates too, such as glass, ceramic, clinker, enamelled surfaces, water and solvent-based varnish, metals in general and on various types of plastic. It is also suitable for contact with absorbent mineral substrates such as concrete, render and fibre-cement. This product generally forms a good bond on the above substrates even if a primer is not applied beforehand (contact the MAPEI Technical Services Department before). Performs well in treated water typically found in swimming pools.
