Tip 1: Enlarge the space

A home in waxed concrete looks larger, and spaces communicate better with one another. 

Everyone dreams of finally being able to eliminate those ubiquitous joints that are sources of clogging and divide up space.

Tip 2: Avoid dirty jobsites

Thanks to its extreme thinness (2 to 3 mm thick), waxed concrete is discreet over existing tiles, creating no extra thickness. Like no other material, it allows you to renovate without changing heights. No need for thresholds, no need to plane doors, at 2 millimeters all-in, it's the thinnest coating available. 

If the tiles are sound, applying them over the top without removing them will reduce noise and dust pollution. It is important to note, however, that this type of application on tiles requires professional know-how, a proper diagnosis and adequate preparation.

Tip 8: Keep it simple

Waxed concrete is one of the simplest stair renovation solutions. Existing staircases covered with adherent tiles can be covered without prior removal. Renovation is therefore quick, generates no waste or dust, and is not noisy.

Visit waxed concrete, on stair tilingcan be applied to all surfaces and adapts to the shape of your staircase: treads, risers, stringers, edges and underside. Its hardness makes it impact-resistant and ensures its durability over time.

Tip 9: Don't neglect the stair nosing

The treatment of the stair nosing is important. If use is not too intense, the corner can be made with waxed concrete.. The steps then have a very uniform appearance, with a single material. 

It's a pure, aesthetically pleasing choice, ensuring simplicity and design in the space. Existing wooden thresholds can be retained. They play a technical and aesthetic role that works well in older buildings.

The contrast of materials is emphasized, giving character to the staircase.

For added protection, thresholds can be integrated in the form of stainless steel or aluminum metal corner strips to withstand knocks on edges.

Modern materials combine to reinforce edges, for example in hotels or public areas. Similarly, podotactile studs for the visually impaired or contrast strips to comply with current ERP standards can be integrated.

Tip 10: Avoid slipperiness

Waxed concrete creates a certain granularity to prevent slippery treads, especially on steam room stairs or stairs used outdoors on wet floors. Marius Aurenti waxed concrete complies perfectly with current standards.

Tip 11: Spruce up your exterior

Because of the wide variations in temperature and humidity outdoors, Marius Aurenti does not apply waxed concrete to old outdoor tiles. Waterproofing is not always reliable, and cannot guarantee tile adhesion. Outdoor use, it is therefore advisable to remove the tiles and return to the raw slab on which the outdoor waxed concrete.

Technical aspects of waxed concrete over tiles

Tip 12: diagnose your soil

Before applying waxed concrete to a tiled surface, it is advisable to diagnose the tiles and determine their state of adhesion by probing. To do this, simply "tap" it with a wooden handle, for example, to see if it sounds "hollow". When an old tile is partially detached, the tiles are removed and re-glued..

If they are too damaged, cracked or missing, they should be filled with epoxy mortar. If more than 10% of the surface is hollow, missing or detached, the risks of applying to such a substrate are too high.. In this case, the entire tiling system has to be removed.

We also need to check for the presence of water, which could damage the work in progress or later. To do this, moisture tests will be carried out, as well as a visit to basements, perimeter walls, etc. The maximum permissible moisture content of the substrate is 4%.

It's also important to spot the cracks that sometimes run through a series of tiles.

Note that these cracks may be in the joints and therefore less visible. Covering "active" cracks means taking the risk that they will reappear if the house continues to move. It is therefore preferable to give them a "working space" by marking a joint in this area. Some craftsmen successfully weave cracks using specific systems, as is done on facades (there is no official technical opinion on these techniques).

The installation of waxed concrete does not require any specific joints on tiled floors, even on underfloor heating, unless existing joints are respected, e.g. peripheral joints, expansion joints, breaks, thresholds, or a change of material.

Once the diagnosis has been made, the floor must be prepared to ensure good adhesion. This is achieved by sanding with a diamond disc and applying a sandblasted epoxy mortar that will ensure the waxed concrete's adhesion and prevent capillary rise as an impermeable barrier.

EPX2 is used on floors - or EPX2 turbo for low-temperature or time-restricted jobs - while EPXC primer is suitable for wall applications.

MA's waxed concrete system always includes an epoxy primer. After these preliminary preparations, the concrete is laid over the primer in two or three coats, followed by the finishing touches. Our training courses enable you to master these procedures and ensure a perfect diagnosis.
