The
Microcement
Marius Aurenti allows you to cover old tiles in just 2 to 3 mm thick. This technical feat was perfected almost 20 years ago, making Marius Aurenti the world pioneer in thin-walled microcement.
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, such as the living room, which can be easily connected to each other with no visual break in the floor and no level between rooms.
How do I apply microcement to living-room tiles?
Professional expertise
Application on tiles requires professional expertise. Indeed, the steps involved in preparing the substrate are crucial to the successful installation of microcement over existing tiles.
Assess substrate condition
It’s important to assess the substrate, whether slab or screed, and to check the condition and insulation of basements.
If part of an old living room tile is badly glued, the tiles are either removed or re-glued. However, if the delamination affects more than 10% of the surface, the entire tile must be removed.
Preparing the living room tiles
Preparation is then essential to ensure tile adhesion, control any rising damp and even out the floor perfectly at joints and outcrops.
Preparing living-room tiles for the application of microcement usually requires an extra two days.
Although easy to install, the use of hydraulic levelling compound to profile a floor (levelling, filling joints, etc.) before applying microcement is not recommended.
Regardless of the type of levelling compound on the market, whether U3 P3 or U4 P4, with or without fiber, on acrylic or even epoxy primer, we have found in more than two decades of jobs that these surfaces can easily come unstuck (blowing) or crack… Unfortunately, whatever the manufacturer and after numerous tests, the result is the same.
Given the risk of transmitting these pathologies to the microcement, hydraulic patching is not recommended. Only epoxy resin in liquid mortar form is used at Marius Aurenti.
Applying an epoxy primer to old tiles, previously sanded with a diamond disk, evens out the surface, ensures the adhesion of microcement and prevents capillary rise.
For floor preparation, consult theEPX2 data sheet, and for wall preparation, theEPXC data sheet. For time-limited or low-temperature floor projects, theEPX2 turbo is used.
This type of application is often carried out when demolishing partitions and rearranging rooms.
Finishing touches
There are different ways to finish microcement, either with finishing strips, by leaving it unfinished, or by incorporating an aesthetic layout.
Application is then made to the prepared substrate in accordance with site standards and conditions.
Construction time
Microcement jobs generally take a week to complete, plus the time needed for the varnishes to dry, so that the site can be put back into service as quickly as possible.
Applying concrete to floor or wall tiles
Microcement can be applied to old tiles on both floors and walls in living rooms, but also in areas such as bathrooms, where waterproofing and airtightness requirements are crucial.
It is advisable to consult a professional to prepare the substrates for such a project.
Protecting concrete with a varnish
Protecting microcement over old tiles is usually done with varnishes. The reputation of Marius Aurenti concrete varnishes and impregnations has been established over the years by their use in the public sector for the creation and protection of works of art.
Marius Aurenti specialty materials
In the materials section, you’ll find the different preparation and finishing products, as well as the different types of microcement.
On old tiles, we generally use Béton ciré Classic, which offers great versatility: application on floors and walls in living rooms, bathrooms and kitchens.
MA’s is committed to guaranteeing the durability of its materials. Proper preparation of the substrate is essential to ensure a beautiful, long-lasting finish.
