Mastherm

MASTHERM is an elastomeric insulating coat based on high grade acrylic resin and fillers to provide a thermal insulation to a wall surfaces and roof. When applied directly to rust will convert iron oxide to iron sulphate, thus preventing further rusting problems.

Non-toxic.

Good adhesion properties.

Repels water vapour and humidity.

Allows the release of any moisture coming up from the ground by
capillary action.

Protect the formation of fungus and algae.

Anti-condensation and high terminal insulation property that reduce
