Microcement over tiles: transforming an interior

Terracotta and old stone may have absorbed oils, waxes or black soap that interfere with adhesion. Cleaning alone may not be sufficient. Tiles laid over timber, levelling compounds, flexible layers or another tiled surface, as well as ground-bearing substrates, require a specific assessment before this system is selected.

Yes, following assessment and with preparation appropriate for vertical surfaces. A floor kit should not automatically be used for walls or showers: preparation, material quantities and waterproofing must be checked for the intended application.

Distinguish the microcement layer, approximately 2 mm for this flooring system, from the epoxy preparation and any levelling work. Total thickness is established after assessment. Doors, thresholds and adjoining surfaces must be checked before work begins.

The reinforced epoxy preparation is designed to prevent the tile-joint pattern from showing through. Expansion joints, contraction joints and other movement joints must not be concealed without appropriate detailing.

The budget depends on the surface area, substrate condition, protective finish and application. Separate the system materials from any repair work, equipment, transport and labour. A materials-only price is not the price of a supplied and installed finish.

The programme includes substrate preparation, microcement application and protection. For HL8 and IF3 systems, allow for the curing period of up to seven days after the final coat before normal use, according to site conditions and the current technical data sheet. A surface that is dry to the touch is not necessarily ready for exposure to water.

Low-temperature underfloor heating may be compatible, subject to conditions. The heating type, substrate condition and shutdown and restart procedure must be checked before application.

This application over existing outdoor tiles is not recommended. Have tile removal and preparation of a substrate suitable for the exterior system assessed.

Where defects are widespread, local repairs may be insufficient. The assessment may indicate that the tiles need to be removed. Covering an active crack or a moisture problem does not resolve the underlying cause.

Substrate stability, preparation and the correct treatment of joints are essential. The conditional non-cracking warranty for installation by an Expert applicator must be considered within its contractual scope; it never removes the need for substrate assessment.

Preparing a tiled substrate is demanding. Practical training and a trial application are useful before committing to the work. A shower, large floor or uncertain substrate calls for support from a trained professional.

Use a cleaner compatible with the protective finish, soft cleaning accessories and felt pads beneath furniture. Observe the curing period before the first cleaning, and avoid abrasives and aggressive products.
