SUBSTRATE PREPARATION FOR MICROCEMENT

CEMENT-BASED SUBSTRATES

*Important: the following technical recommendations guarantee a satisfying result as long as the work project runs smoothly. However, we always recommend that the professional evaluate and carry out a tasting of the substrate before starting the project in order to decide on the best solution. This will avoid possible unexpected events affecting the state of the microcement.

Before applying microcement, check that the substrate is in good condition. The tensile strength should be 1.5 N/mm2 “Pull-off test”. If this is not the case, a concrete consolidator should be applied. If there is humidity we will apply a vapour barrier called Vapoepox 100, an anti-humidity epoxy primer. Finally, apply two coats of Microcement Base.

 PREPARATION

Compactec “If the substrate is of low quality”
+
Vapoepox 100 + Mesh “If there is a lot of humidity”
+
Microröck or Microflex Base

 *Which microcement base do I use out of the two? There is a basic concept and that is when something is very hard it has less elasticity and vice versa.With this concept we will use Microröck Base if what we want is a very resistant and hard support. If, on the other hand, we prefer a more elastic support that avoids cracking, we will use Microflex Base.

UNDERFLOOR HEATING SYSTEMS

For radiant floors, Microdur or Microflex, heat-conducting microcements, must be applied directly.

PLASTERBOARD

As it is a very porous surface, it will be necessary to use primer TAC + Mesh.

TILES

Due to the joints, a joint filler, a special epoxy joint filler and joint smoothing compound must be used.

WOOD

As it is a very flexible material, we will use Microflex base, perfect to support the contractions and expansions of the material.

SWIMMING POOL

For the areas that contain water, we will apply Base Micropool, as it is waterproof in mass.
