Mineral mortars

It is used for manual or machine application of renovation top coat on walls with salt efflorescence inside and outside buildings (above the ground level). It is used as a layer which absorbs dissolved salts while applying three-layer (TB + TW + TU) renovation top coats with MINERALIT RESTAURO products. It makes up a coat of high pore volume due to which it can absorb large amounts of salt formed in wet walls. It features a short setting time and a high level of adhesion to hard substrates, it is not especially sensitive to differentiated level of wall absorptivity (e.g. in the event of wide joints in walls made of stone). It is especially recommended for renovation of historic buildings. To be used on walls made
of stone and bricks of high and average salinity.

• For the renovation of walls with salt efflorescence and moisture
• Very high ability to absorb harmful salts
• Extended processing time
• Very high porosity
• High adhesion to difficult substrates
• High vapour permeability
• For manual and machine processing
