Data Sheets
Mapetherm Net is an alkali-resistant glass fibre mesh, suitable for reinforced skimming layers when repairing façades, or for the execution of MAPETHERM thermal insulation systems and Mapewall GPR.
Mapetherm Net is for use on top of render base coats as a reinforcement. The Silancolor Base Coat & Silancolor Tonachino Top Coat can be applied on top.
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 (where used). Once the reinforcing coat has hardened, the 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.
Each roll is 50 metres long by 1 metre wide.
For relevant products which work with the Mapetherm Net system, please see Mapewall GPR and Mapetherm AR1 GG.

Mapetherm Net is a reinforcement mesh for:
a) protective reinforcing coats on façades and render with micro-cracks or crazing;
b) reinforcing coats on thermal insulation systems made with Mapetherm AR1, Mapetherm AR1 GG, Mapetherm AR1 Light, Mapewall GPR, Mapetherm AR1 Maxi or Mapetherm Flex RP.
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 1-2 mm thick and, if necessary, finish the surface with a damp sponge.
When applying Mapetherm Net, make sure the edges of each piece overlap by at least 10 cm to form a seamless layer of reinforcement.
