Mapesil LM
Verified by manufacturer over a year ago
The neutral pure silicone sealant ideal for natural stone. Solvent-free and mould-proof.
Application
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.
Suitable for particularly delicate materials such as bricks, cellular concrete and varnished or enamelled wood.
Suitable for contact with absorbent mineral substrates such as concrete, render and fibre-cement.
Suitable for sealing internal and external fillet and expansion joints, including those subject to high levels of movement when in service such as:
- Pre-fabricated panels.
- Window/door fittings and wall surrounds.
- Pipe-work and vertical walls.
- Similar and/or different types of coating materials.
Also suitable for sealing joints in floors with limited pedestrian traffic.
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).
