Uses

Recommended For:
Sealing materials sensitive to acids and plasticizing agents, such as marble, granite, sandstone, and quartz.
Sealing delicate materials like bricks, cellular concrete, varnished, or enameled wood.
Sealing non-absorbent substrates such as glass, ceramic, clinker, enamelled surfaces, varnished metals, and various plastics.
Contact with absorbent mineral substrates like concrete, render, and fiber-cement.
Sealing joints subject to high movement levels, including expansion joints between pre-fabricated panels, window/door fittings, pipe-work, and vertical walls.
Sealing joints in floors with limited pedestrian traffic.
Sealing joints in swimming pools with treated water.

Not Recommended For:
Applying on rubber, heavily-plasticized plastics, or bitumen, as migration of oil and plasticizing agents from the substrate may compromise the bond or alter the sealant's color and mechanical properties.
Prolonged exposure to treated water typically found in swimming pools without specific laboratory testing to assess suitability.
Sealing floors subject to intense traffic; consider using Mapeflex PU45, Mapeflex PU20, or Mapeflex PU21 instead.
Using Primer FD when sealing stone or marble due to potential compatibility issues.

Mapesil LM is a one-component, solvent-free, neutral-cure silicone sealant which does not emit unpleasant odours,
available in the form of a thixotropic paste. It is easy to apply on vertical and horizontal surfaces and cures at room
temperature through the humidity present in the air to form a flexible sealant.
Seals made using Mapesil LM are extremely stable over time, even when exposed to inclement weather, industrial
environments, temperature variations or water. The product remains flexible over a temperature range of between -40°C
and +150°C.
Mapesil LM delays the formation of surface mould.
Mapesil LM generally 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).
Primer FD must be applied beforehand in the case of prolonged immersion in water.
If in doubt, please contact the MAPEI Technical Services Department or carry out preliminary tests beforehand.
Mapesil LM is particularly suitable for surfaces sensitive to acids on which conventional neutral or acid sealants normally
provoke changes in colour or staining of the substrate.
Mapesil LM complies with EN 15651-1 norm (“Sealants for internal and external façade elements”) with performance rating
F-EXT-INT-CC, with EN 15651-2 norm (“Sealants for glazing”) type G-CC, with EN 15651-3 norm (“Sealants for joints in
sanitary areas”) type XS1 and EN 15651-4 norm (“Sealants for pedestrian walkaways”) with performance rating PW-EXTINT-
CC.
