PREPARATION OF SURFACES FOR MICROCEMENT

Work prescription

microcement-prep-soportes_cemher-002

*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, we must prepare the substrate to avoid future problems. For this reason, we have listed the most common substrates in construction. Depending on each one, and its circumstances, we will have to use some products or others.

CEMENT-BASED SUBSTRATES

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.

SUPPORTS

Concrete floors
Ready-mix self-leveling mortars
Bagged self-leveling mortars
Other mortars

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.

SUPPORTS

Anhydrite self-levelling

PREPARATION

Microdur or Microflex base

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.

SUPPORTS

Ceramic tiles
Porcelain tiles
Natural stone or limestone
Marble
Glass tiles
Hydraulic tiles

PREPARATION

Jointepox (Sealing cap)

Microröck or Microflex base

WOOD

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

SUPPORTS

Floorboards
Parquet

PREPARATION

Microflex Base
