Technical Specifications:

Application Conditions:

Substrate primer: EWI- 301

Application temperature (air, substrate, materials): from +5°C to +25°C

Quantity to be used: approx. 1.8 kg/m2 per 1mm of layer thickness (dry mix)

Directions for Use:

Substrate Preparation: Substrates for fixing insulation panels must have sufficient load-bearing capacity, 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 by with a wire brush as necessary and rinsed with water and allowed to dry. Highly absorptive and dusty substrates should be primed with EWI-301.

Product preparation: Slowly add the dry mixture to a container with clean cool water, stir by slow-speed mechanical mixer to achieve a uniform, lump-free consistency. Allow to cure for about 5 minutes and then mix again thoroughly.


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.

  1. Rated 5 out of 5

    Just used this on our latest rendering job to get the wall sorted before putting on the rest of the gear. It is very good stuff. In fact all the bits are first rate, on a par with Sto and much cheaper than K-rend. Would defintely recommend

  2. Rated 4 out of 5

    Quite good mortar with acceptable price. Would recommend.
