Textured plaster and microcement: finishes, uses and pitfalls
A guide to lime plaster, tadelakt, textured paints and microcement for villa walls and floors: looks, durability, wet areas, application and common failures.
Textured wall finishes have become a defining feature of contemporary villas: soft lime-plaster walls, sculpted TV walls, seamless microcement bathrooms. They bring depth and a handmade quality that flat paint cannot, and they catch light beautifully. But they are also applied by hand, on site, and their success depends heavily on the substrate and the skill of the applicator.
The main families
| Finish | Look | Best for |
|---|---|---|
| Lime plaster (e.g. Venetian, marmorino) | Soft, cloudy, sometimes polished | Living rooms, bedrooms, entrances |
| Tadelakt | Smooth, waterproof lime, soap-sealed | Bathrooms, niches |
| Textured mineral paint | Matt, chalky, subtle movement | Large walls, budget-conscious projects |
| Relief plaster | Sculpted, three-dimensional | Feature walls, TV walls |
| Microcement | Seamless, concrete-like | Floors, bathrooms, kitchens, furniture |
Lime plasters
Lime-based plasters are breathable, naturally resistant to mould and develop a soft patina over time. Polished versions such as Venetian plaster have depth and a gentle sheen; matt versions feel warm and chalky. They are ideal for living rooms, bedrooms and entrance halls, and they combine well with timber and stone.
Relief and sculpted walls
Relief plaster can create waves, lines, arches or even figurative motifs, as in several of our villa projects. These feature walls work best with grazing light from above or the side, which reveals the texture. Plan the lighting and any recesses for TVs or shelves before the plaster is applied.
Microcement
Microcement is a thin, cement-based coating, typically 2–3 mm, applied in several layers and sealed. It creates a seamless surface on floors, walls, stairs, worktops and furniture, with no joints. It is popular for bathrooms and open-plan floors.
Its weak points are the substrate and the application. Microcement follows any movement or crack in what is underneath, so it needs a stable, well-cured base, reinforcing mesh and movement joints where the substrate has them. On floors, choose a system rated for foot traffic and reseal as recommended.
In wet areas
Both tadelakt and microcement can be used in bathrooms and showers, but only over a proper waterproofing membrane. The finish itself is not the waterproof barrier. Seal carefully, avoid harsh cleaning products and expect a patina over time. Our guide to villa bathroom design explains waterproofing in detail.
Common failures and how to avoid them
- Cracks: from unstable substrates, missing mesh or too-thick layers. Prepare the base properly.
- Blotchy colour: from uneven suction or rushed drying. Prime and control curing.
- Stains on microcement: from inadequate sealing. Use the right sealer and reseal.
- Visible joints between days of work: plan to finish each wall in one session.
- Disappointment with the result: always approve a large sample board on site.
Samples and approval
Because every applicator's hand is different, ask for a sample of at least 50 × 50 cm, ideally on the actual wall, and look at it in both daylight and artificial light. Keep the approved sample on site as a reference.
Cost and time
Hand-applied finishes take longer than paint: several coats, drying times and sealing. They cost more per square metre, but on a single feature wall the impact far outweighs the extra cost. Microcement floors are often compared with large-format tiles; installation time, substrate preparation and maintenance should all be part of the comparison.
For feature walls combined with media units, see built-in TV wall design. For stone alternatives, read natural stone vs porcelain floors, and for entrance walls, entrance hall design.
Frequently asked questions
Can microcement be used in a shower?
Yes, if it is a system designed for wet areas, applied over a proper waterproofing membrane and sealed with a suitable sealer. The waterproofing below the microcement does the real work; the finish alone is not a waterproof barrier.
Does textured plaster crack?
Hairline cracks can appear if the substrate moves or the plaster is applied too thickly or dries too fast. A stable substrate, reinforcing mesh at joints and correct curing times reduce the risk considerably.
How is textured plaster different from textured paint?
Mineral plasters such as lime are applied with a trowel in several thin layers and have real depth and variation. Textured paints are applied more quickly and are cheaper, but the effect is flatter and more uniform.
