UNILIT 10 is a bonding layer based on natural hydraulic lime and silica sand, of a maximum granulation of 4 mm. UNILIT 10 functions within the UNILIT system as a bonding bridge between the weak substrate and the insulating mortar UNILIT 20, the mortar UNILIT 25, 30 or 35.
UNILIT 10 is applied when the background is unsuitable to guarantee an optimum bonding of the UNILIT mortar. Surfaces with a closed structure such as concrete slabs and very old masonry will have to be treated with UNILIT 10. Substrates completely saturated with water must also be pre-treated with UNILIT 10. Applied in open structure the product will not impair the permeability of the wall.
