EXCEPTIONAL BONDING PROPERTIES ON MOST SUBSTRATES
AD LUCEM microcement has special adhesion properties that allow it to be applied onto most substrates encountered in construction, either in new or renovated buildings.
The cohesion is perfect on slabs, screeds, self levelling compounds but also on tiling. The specific primers and undercoats allow for the vertical applications such as on plasterboard, agglomerated wood panels, plaster, old paintings, etc...
AD LUCEM microcement is also perfectly adapted for underfloor heating.
MICROCEMENT ON CONCRETE SLABS, SCREEDS, SELF LEVELLING COMPOUNDS
The ideal mineral substrates
Concrete slabs and screeds are mineral substrates which by definition are the best substrates for microcement
This type of substrates generally receives a surface treatment during the installation. A curing compound may have been sprayed on the surface and the concrete might still be covered with releasing oil. It is imperative to treat these surfaces to remove these products and to open the pores.
Surface sanding or scrubbing allows the use of microcement without any risk.
There can be two kinds of screeds:
* Cement screeds, which have the same compatibility and characteristics as the concrete substrate.
* Anhydrite screeds, gypsum based, which have the advantage of being much less prone to cracks. The Anhydrite screeds are the HIGHLY RECOMMENDED ONES for microcement.
They can be cement based, sometimes with fibres, or anhydrite based (gypsum).
Against cracks, the anhydrite gives much better guarantees. Be careful, however, to always choose the technical solution that can avoid -if possible- the use of self levelling compounds because the risk of disorders are often generated by these sub-layers. The application processes of AD LUCEM microcement allows to avoid their uses in many cases.
MICROCEMENT ON EXISTING TILES
Microcement is often applied in renovation due to its thickness and makes it possible to apply without being forced to carry out big preliminary demolition works. It brings a beautiful decorative solution that becomes easy and competitive to install.
The preparation work
It is necessary to ensure the good adhesion of the existing tiles before the application of microcement and it is necessary beforehand to grind the tiles to deglaze them and to remove the misalignments (lips etc..). A levelling layer with our products can then be applied to the entire surface. This preliminary work is essential to avoid the appearance of "ghosts" during the application of the microcement system.
The preparation tools & materials
It is essential to have powerful and adapted equipment to carry out these projects. With regard to grinding and sanding for example, a grinder type PG 450 from Husqvarna is essential. All sanding of the substrates and our microcement is done with diamond tools.

MICROCEMENT ON VERTICAL SUPPORTS
Mortars, plaster, paintings etc...
The walls can be of any kind, from cement or lime mortar, gypsum plaster, bricks to plasterboard and derivatives as well as tiles, composite woods and paints.
A simple preparation with the appropriate primers is sufficient when the substrates are healthy and cohesive.
At a glance :
Suitable for surfaces such as plasterboard and plastered masonry surfaces. sand and cement renders, MDF, marble, concrete.
All substrates need to be fully cured, free from dust, salts, oils and other impurities.
Substrates need to be flat and even with no ridges or bumps.
Will not stop substrate cracks appearing on the surface, if a weak substrate is not correctly prepared and reinforced.
