Processing details
Learn more about technical details for processing this product.
Substrate requirement
The substrate must comply with the applicable standards, must be solid, free of loose particles, free of dust, paint, residues of demoulding substances and efflorescence. It must be sufficiently rough, dry and evenly absorbent. The surface shall not be frozen or water-repellent. The substrate must be stable in volume.
Substrate preparation
Depending on the absorbency of the substrate and climatic conditions, especially in warm weather, moisten the masonry sufficiently to prevent the mortar from drying out prematurely.
Preparation of the mixture
Prepare the material by pouring the dry mixture into the prescribed amount of water and mixing it. Use potable water or water complying with EN 1008 to mix the mixture. Mix using a slow speed propeller mixer. Mix to a homogeneous, lump-free mixture and leave to rest. Then mix again briefly. Use suitable machinery when processing by machine.

Mixing
Processing instructions
Masonry: Spread the material on the prepared substrate (e.g. masonry element) with a trowel or a suitable tool. Immediately after applying the mortar, set the masonry element and level it.
Grouting: Apply the material by hand, using an application gun or other suitable machinery. Then smooth the joint to the required shape and surface using a suitable tool according to the width and shape of the joint. Protect the applied material from fast drying, direct sun, rain and frost.
