In an interior, a tiled floor has an impact on the entire d\u00e9cor of the home. An old bathroom tile can be a hindrance to the creation of a new decor, and can often be a source of wear and tear.<\/p>\n

Marius Aurenti microcement can be used to cover old tiles in a thickness of just 2 to 3 mm.<\/strong> This technical feat was perfected almost 20 years ago, making Marius Aurenti the world pioneer in thin-walled microcement.<\/strong><\/p>\n

Performance tests show that 2 mm of Marius Aurenti microcement has extremely high mechanical strength (see technical data sheets). Thickness and strength allow microcement to be used in all living areas, which can be easily connected to one another with no visual break in the floor and no level between rooms. No extra steps or need to fit a rod to compensate for a difference in level.<\/p>\n

How do I apply microcement to bathroom tiles?<\/h2>\n

Application on tiles requires professional know-how. Preparing the substrate is a decisive factor in the successful installation of microcement<\/a> over old tiles.<\/strong>.<\/p>\n

Diagnosis<\/h3>\n

We need to diagnose the substrate, whether slab or screed, and determine the condition and insulation of basements.<\/p>\n

Substrate preparation<\/h3>\n

Preparation is then required to ensure adhesion to the tile, block out any rising damp and perfectly level the floor at joints and outcrops. Preparing tiles for microcement application generally requires an additional two days.<\/p>\n

This type of application is often undertaken when demolishing partitions and remodeling rooms.<\/p>\n

Finishes<\/h3>\n

Microcement can be finished in a number of different ways: using finishing strips, leaving it unfinished or inserting an aesthetic pattern.<\/p>\n

Application is then made to the prepared substrate in accordance with site rules and conditions.<\/p>\n

Site duration<\/h3>\n

Microcement jobs generally take a week to complete, to which must be added the time required for the varnishes to dry before the site can be put back into service.<\/p>\n

Application of microcement over tiles<\/h3>\n

The application of microcement over old tiles can be done on the floor or wall in a living room, but also in a bathroom where waterproofing and airtightness constraints are decisive.<\/p>\n

Professional advice should be sought to prepare the substrates for such a project.<\/p>\n

Varnish protection<\/h3>\n

Protecting microcement over old tiles is usually done with varnishes. The reputation of Marius Aurenti concrete varnishes has been built up over the years through their use in the public domain for the construction and protection of engineering structures.<\/p>\n

Materials<\/h3>\n

In the materials<\/a> section, you’ll find the different preparation and finishing products, as well as the different types of concrete.<\/p>\n

Before \/ after<\/h2>\n

Renovating old tiles with microcement is the ideal solution for a clean worksite and a unique aesthetic result.<\/p>\n

Microcement is applied over sound tiles with a primer. In the bathroom, microcement<\/a> can be applied to all surfaces: walls, floor, walk-in shower, tub surround, basin, vanity top, furniture… Microcement can be maintained with conventional detergents or MA’s specialized maintenance products<\/a>.<\/p>\n

Where should tiles not be laid?<\/h2>\n

Marius Aurenti does not carry out application work on old outdoor tiles, as temperature and humidity variations are too great.<\/p>\n

And if the waterproofing is unreliable, tile adhesion is not guaranteed.<\/p>\n

For outdoor applications<\/a>, MA’s recommends systematically reverting to the raw slab on which the microcement will be applied, slab quality permitting. In the case of irregularities or defects in flatness or slope, corrections can be made before applying the microcement.<\/p>\n

Another special case is tile adhesion defects. A preliminary survey tests the adhesion of the tiles to the substrate. If visible defects are evident (cracking, delamination), the work is not carried out, or undergoes a specific preparation phase approved by the CSTB.<\/p>\n
