Technical Data


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
Performs well in treated water typically found in
swimming pools.
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.
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
