Microcement on floors, walls and bathrooms: guide 2026

Microcement is a seamless coating just a few millimetres thick applied over floors, walls, bathrooms and even worktops, often with no demolition and straight over existing tiles or flooring. It gives a modern, joint-free finish that is water-resistant once sealed, ideal for bringing a fresh look to Costa Blanca homes with little mess. Its durability depends on good application and sealing. The most useful step is a personalised, no-obligation quote.

Microcement has become one of the most requested finishes in Costa Blanca renovations for its modern look and, above all, because it can often be applied without any demolition. It is a continuous cement-and-resin coating, barely 2 or 3 millimetres thick, that bonds over existing floors, walls and tiles. The result is a seamless surface with a look somewhere between industrial and warm, transforming a room with quick, clean works.

Where microcement can be applied

  • Floors in living rooms, kitchens, hallways and bedrooms, with a seamless finish that makes the space feel larger.
  • Walls in the living room, hallway or bedroom for a modern, joint-free backdrop.
  • Complete bathrooms: shower trays, walls, worktops and basins, thanks to its good water resistance once sealed.
  • Kitchens: fronts, worktops and islands with a continuous look.
  • Over existing tiles or flooring, avoiding demolition and waste.
  • Stairs, bespoke furniture and even pools with the right system.

Applying microcement over existing tiles

One of its great advantages is that it can be applied over current tiling or flooring without removing it, provided the base is firm and well bonded. The surface is cleaned and primed, the tile joints are filled so they do not show through, and the microcement layers and final sealant are applied. This avoids demolition, waste and dust, shortens the works and barely raises the floor level, so doors and skirting often do not need touching. It is the ideal way to update a bathroom or living room without an aggressive renovation.

Pros and cons of microcement

  • For: seamless, joint-free finish, modern look and many colours and textures.
  • For: applied over what is already there, with little mess, little dust and short timescales.
  • For: minimal thickness, suitable for floors, walls and wet areas once sealed.
  • Against: it needs highly skilled labour; a poor application shows and is unforgiving.
  • Against: it is a handcrafted material, with slight tone variations that are part of its character.
  • Against: it needs good sealing and proper maintenance to keep its resistance.

Maintenance and cleaning in coastal homes

On the Costa Blanca, beach sand and salt are the main enemies of any floor, and microcement handles them well precisely because it has no joints where dirt can build up. Clean it with a well-wrung mop and a neutral soap, avoiding abrasive, acidic or bleach-based products that could damage the sealant. It pays to remove sand regularly so it does not scratch the surface, and to reapply a coat of sealant or wax now and then in high-traffic areas. That keeps the finish looking immaculate for years.

Durability: what to expect from microcement

Applied and sealed well, microcement is a very durable coating that stands up to constant foot traffic, water in the shower zone and the marine environment. Its lifespan hinges on two key factors: the quality of the application (number of coats, curing and professional sealing) and the maintenance afterwards. A hairline crack can appear if the base moves, which is normal for a continuous material and is repaired locally. Choosing a team experienced in microcement is what makes the difference between a finish that lasts and one that disappoints.

What microcement costs: the factors

The price of microcement is not a fixed figure but depends on several factors: the square metres to coat, whether it goes on a floor, a wall or wet areas such as a bathroom, the condition and firmness of the existing base, the number of coats and the type of finish and sealant, the colour and texture chosen, and the complexity of the surface (stairs, worktops, corners). Applying it over a base in good condition reduces the preparation. That is why the sensible move is to assess your specific home and request a personalised, no-obligation quote.

Frequently asked questions

How much does microcement cost on a floor or bathroom?

There is no single price: it depends on the square metres, whether it goes on a floor, wall or wet area, the condition of the existing base, the number of coats and the finish and sealant chosen. Applying it over a firm base reduces preparation. We visit your home and prepare a personalised, no-obligation quote.

Can microcement go over tiles without removing them?

Yes, it is one of its great advantages. As long as the tiling or floor is firm and well bonded, it is cleaned, primed, the joints are filled and the microcement is applied over the top. This avoids demolition, waste and dust, and greatly shortens the works.

Is microcement water-resistant enough for a bathroom or shower?

Yes, once the right sealant is applied microcement resists water well and is regularly used on shower trays, bathroom walls and worktops. The key is good waterproofing of the base and professional sealing, plus cleaning with neutral products that do not damage the finish.

Does it cope with the sand and salt of beach houses?

Yes. Having no joints, microcement does not trap dirt and is easy to clean, which suits coastal homes well. It pays to remove sand regularly so it does not scratch, clean with a neutral soap and renew the sealant periodically in high-traffic areas.

Does microcement crack over time?

Applied well over a stable base, microcement is very durable. Hairline cracks can appear if the base moves, which is normal for a continuous coating and is repaired locally. The quality of the application and sealing, plus proper maintenance, is what ensures it lasts for years.
