EWI-260 Levelling Mortar is used on walls to prepare an uneven substrate prior to applying render for EWI-Pro solid wall insulation systems. Made from a mixture of Portland cement and mineral fillers, it can be used for repairing and filling cavities in walls.
Our EWI-260 levelling mortar is used on walls to produce a smooth surface on which a basecoat or EWI system can be applied. The Levelling Mortar can be used to fill and repair holes and other imperfections up to a maximum thickness of 50mm, and the mortar can be applied on various different walls and substrates, including existing pebbledash, concrete as well as different types of block or brickwork.
Substrate Preparation: Substrates must have sufficient load-bearing capacity, must be stable and free of contamination which might affect the adhesion properties of the mortar e.g. dust, oil, moss, loose and peeling paint or plaster coats. Remove all loose or peeling plaster coats. The wall surface, plastered or not, should be cleaned with a wire brush as necessary then rinsed with water and allowed to dry. Highly absorptive and dusty substrates should be primed with EWI-301 Water Based Primer.
Product preparation: Slowly add the Levelling Mortar dry mixture to a suitable container containing 4 litres of clean cool water. Once the Levelling Mortar has been added to the water, mix using a paddle mix to achieve a uniform, lump-free consistency. Set aside the levelling mortar for 5 minutes and then mix again thoroughly before applying to the substrate.
Applying the product: Apply EWI-260 Levelling Mortar to the substrate with a trowel up to a maximum thickness of 50mm. Smooth out the layer to prepare a level surface ready for further works. EWI-260 needs to be left for a minimum of 48 hours before any more works are carried out.
The Coverage rates of Levelling Mortar are variable and depend upon how much is required for the surface of the wall.
