Protective reinforcing mesh on render and facades with micro-cracks or crazing
Reinforcing coats on thermal insulation systems
Technical Characteristics
The mesh is made from glass fibres treated with a special primer which makes it resistant to alkalis and improves its adhesion to all MAPEI renders
Once the reinforcing coat has hardened, Mapetherm Net reinforces the layer to prevent cracks forming due to movements in the substrate or hygrometric shrinkage.
It also makes it easier to apply an even reinforcing coat around 2-3mm thick and increases its strength and resistance to temperature variations and abrasion.
Application
Mapetherm Net must be completely embedded in the skim coat as follows:
Trowel-apply a layer of reinforcing compound according to the thickness permitted by the trowel
While the reinforcing compound is still fresh, lay Mapetherm Net on the surface and press it gently with the trowel so that it is embedded
Wait for the reinforcing compound to dry usually 12 to 24 hours depending on the type of product used, the thickness applied, the surrounding temperature and level of humidity
Apply a second layer of reinforcing compound around 1-2mm thick and, if necessary, finish the surface with a damp sponge
When applying make sure the edges of each piece overlap by at least 10 cm to form a seamless layer of reinforcement
