Frequently Asked Questions
WHAT IS THE STRENGTH OF MICROCEMENT?
Despite its lack of thickness, one of this material’s most significant properties is its high resistance and hardness; Microdeck and Microstone can even be used in areas of high traffic.
Several factors influence the resistance and hardness of microcement, such as the support on which it is applied, the type of microcement chosen, as well as the sealant used on the finished microcement.
We can differentiate between two types of resistance:
To blows: Microcement, due to its limited thickness, will deform in the event of a strong blow if the support beneath deforms. An example would be the microcement applied to plaster. If the base deforms because it has poor resistance, the microcement will deform as well. While on a support like terrazzo, the resistance will be greater.
To abrasion and wear: This resistance depends on both the microcement type and the sealant. Topciment has two seamless floor coverings: Microdeck and Microstone. Both are coatings with selected aggregates of a larger particle size than that of Microfino, which makes them more resistant to compression and abrasion. Microfino, due to its lower strength, is used exclusively for wall covering. As for sealants, although the resistance is the same, the higher the gloss, the more visible the marks of wear. Matte finishes do not reflect the light, or do so only minimally.
To stains and liquids: The chemical resistance will depend on the sealant used to protect the product. The sealant is the final layer, which is what gives the product protection and impermeability against stains. Our Topsealer sealants have a high chemical resistance, confirmed by the various tests conducted:
Oil, cola, red wine and similar, do not leave stains after cleaning.
Both vinegar or lemon juice leave slight marks on microcement. These acids affect the surface as they would on marble, but if cleaning is done quickly, there will be no stains.
The spots of Salfuman / hydrochloric acid, pure bleach, acetone and ammonia will mark after a half hour of exposure, but if cleaning is done quickly, no stains will remain. It is important to consider microcement’s texture and the difficulty of cleaning.

Microcement can be applied to almost any type of surface: cement mortar, self-levelling compound, hardboard, plywood, marble, tile, plasterboard, over existing plaster and many many more. Microcement can also be applied on both vertical and horizontal surfaces in interior and exterior spaces.
The surface must be stable and dry and free of dust or grease.
One of the main properties of microcement is its high adhesion. Thanks to this it is possible to apply microcement on tiles, speeding up the renovation process and avoiding the debris of the original lining. In most cases, we would use fibreglass mesh to strengthen the support of the microcement layers.
WHAT ARE THE DIFFERENCES BETWEEN MICROCEMENT AND POLISHED CONCRETE?
Although the aesthetic finish may appear similar, it is not the same.
With microcement one benefits from the following advantages:
- Faster application with microcement
- Microcement has no wait time between pour and polish as polished concrete does (which can save 6 weeks!)
- Microcement requires no large machinery or heavy plant tools required for its application.
- Less time. Lower Cost.
- Microcement is infinitely lighter and thus avoids structural load difficulties.
- It is also 2-3mm deep rather than 50-100mm deep
- Microcement can be used in any room, not just on ground floors and basements.
- Microcement has no joints involved, so no hairline (or larger) cracks appear following the drying process.
- Microcement application possible on both vertical and horizontal surfaces.
IS MICROCEMENT WATERPROOF?
Microcement has seamless, crack-proof and waterproof qualities. It is often used in bathrooms, showers, kitchen counters, wet rooms, as external renders, patios and even in swimming pools. All of the advantages of tiles or external concrete / render with the benefit of no lines, cracks and the endless beautiful appearances to accompany.
IS MICROCEMENT NON SLIP?
Microcement with Microcement in London comes in several forms some of which naturally have more grit and texture to offer non slip support. Other types of finer finished Microcement such as the Microfine range are not naturally non slip but can have a non slip element added to the final sealants to ensure they are safer underfoot whilst still sleek and smooth to touch.
HOW LONG DOES A MICROCEMENT INSTALL TAKE?
A typically install will take 5-7 days. This consists of the following;
Day 1). Preparation - Epoxy base where required. Fibreglass mesh laid and stuck with water based compound
Day 2). First Coat of Microbase trowelled on.
Day 3). First Coat of Microbase sanded down with electric hand held sanders. Second Coat of Microbase trowelled on.
Day 4). Second Coat of Microbase sanded down with electric hand held sanders. First Coat of final Microcement Compound trowelled on (fine, deck, stone)
Day 5). First Coat of final Microcement Compound (fine, deck, stone) sanded down. Second coat of final Microcement compound trowelled on
Day 6). Second coat of final Microcement compound sanded down. Final 4 coats of presealer and sealer applied. This gives floor / walls ultimate protection, non-slip elements where required and the final desired finish (matte, satin or gloss)
