Is microcement suitable for bathroom and shower floors?

Yes, with the specific wet-area range of microcement and sealing with polyurethane resin. For a floor-level shower a waterproofing membrane is also applied beforehand (such as Schlüter or similar) under the microcement.

Can Venetian stucco be applied over plasterboard?

Yes, with the right preparation. Full filling of joints and screws, sanding to a uniform surface, fixing primer and application of the stucco layers. The plasterboard substrate is compatible as long as it is well screwed and the joints are treated.

Microcement, stucco and coatings

Decorative finishes: microcement, stucco and continuous coatings in Málaga

Decorative finishes are the visual closure of the works: continuous microcement, Venetian stucco, resin coatings, mouldings and refined skirting. They are neither paint nor plasterboard: they are a category of their own that demands specific preparation.

What it involves

The finish defines the final result

Continuous microcement is the most demanded finish in contemporary renovation: visual continuity, no joints, and the ability to finish floor, walls and worktops with the same material. It is a polymer-modified cement applied in several thin layers over a stable substrate, with a total thickness of 2–3 mm.

Classic stuccoes (Venetian, lime, tadelakt) revive traditional techniques and are used in character homes or signature spaces. Resin coatings or sprayed mortars add texture and allow personalisation of colour and grain. All of them share the same dependency: a badly prepared substrate ruins the finish.

Applications

Three contexts where decorative finishes replace the conventional

Microcement, stucco and continuous coatings are not an alternative to paint: they are a category of their own that solves problems paint does not cover. These are the three most demanded contexts of use.

layers

Continuous floors and walls

Jointless microcement in living room, corridor, bathroom or kitchen to achieve visual continuity between rooms with no material change. Also resolves cases where no height can be lost.

brush

Stucco in signature spaces

Venetian or lime stucco on an accent wall (fireplace, headboard, entrance hall) or in the restoration of traditional homes with solid brick or rammed-earth walls.

texture

Textured coatings

Sprayed or trowelled mortars with smooth, scored or coarse finishes. Interior façades, covered patios or signature walls with a texture requirement.

Finish families

Microcement, stucco and mortar: three families with distinct execution

Continuous decorative finishes fall into three major families with different composition and execution. Choosing the right one depends on substrate, use and intended look.

layers

Continuous microcement

Best fit

Polymer-modified cement applied in several thin coats (2-3 mm total) over a stable substrate. Final seal with polyurethane resin. Ideal for floors, walls and worktops.

Worth knowing

Quality depends entirely on the applicator: it is not painter work. Substrate microcracks can show through if the base coat is not reinforced correctly.

brush

Venetian stucco

Best fit

Overlaid layers of pigmented fatty lime applied with a Venetian trowel and polished while fresh to a gloss. Traditional technique that recovers the Venetian palace look.

Worth knowing

Highly specialised, slow trade: 4 to 7 days per wall. No spot touch-ups allowed — a damaged area forces reapplying the whole wall.

invert_colors

Lime stucco (matt, breathable)

Best fit

Fatty-lime mortar applied in several coats with a matt finish. Breathable, ideal for traditional walls with capillary damp after resolving the cause.

Worth knowing

Cannot be sealed with plastic paints or resins: it would lose its breathable property. Colour range is limited by lime-stable mineral pigments.

texture

Sprayed or trowelled mortar

Best fit

Mineral or acrylic mortar with textured finish (smooth, scored, coarse) applied with trowel or spray gun. Common option for internal patios and signature walls.

Worth knowing

Needs a firm, flat base: it does not correct unevenness or structural cracks. In splash areas it requires specific sealing.

Decorative finishes

The final layer that gives the home its character

Microcement, lime, tadelakt or decorative mortars are applied over a prepared substrate. The surface preparation decides whether the finish lasts five or twenty years.

Control points

Four fronts we review before applying

A decorative finish does not correct substrate defects: it amplifies them. Before applying anything we verify four fronts that decide the lifespan of the finish.

water_damage

Substrate moisture

Measurement with a hygrometer. A substrate with active moisture (capillarity, condensation, leak) causes blisters and detachment within weeks.

straighten

Real flatness

Check with straight edge before ordering material. Microcement does not correct unevenness: it makes it more visible under raking light.

air

Ventilation and use

Bathrooms without forced extraction or small kitchens limit the suitable finish family due to accumulated humidity.

account_tree

Trade sequencing

Plasterboard filled, perimeter paint and floors protected before the finish: a wrong order forces reapplication.

Light and texture

The finish only exists under the right light

Tadelakt, lime wash and microcement change dramatically with grazing light. A sample board under the real lighting of the room is the only reliable test.

Typical scope

What this service includes

We cover the most demanded finish families in both contemporary and traditional renovation.

layers

Continuous microcement

Several thin layers applied on floor, wall or worktop. Jointless finish, sealed with polyurethane resin. Standard in bathrooms, kitchens and living rooms with a contemporary look.

brush

Venetian stucco

Glossy finish by overlaid lime-and-pigment layers, polished while fresh. Traditional technique that recovers the Venetian palace look.

opacity

Lime stucco

Matt and breathable finish, ideal for traditional homes or restoration. More appropriate than plastic paint on old brick or rammed-earth walls.

grid_view

Textured coatings

Sprayed or trowelled mortars with different finishes (smooth, scored, coarse) for interior accent walls.

border_outer

Mouldings and refined skirting

Decorative ceiling mouldings, lacquered timber or plaster skirting, integrated LED profiles. Final details that mark the quality of the finish.

waterproof

Specific sealers

Microcement sealed with polyurethane resin for floors and wet areas; stucco sealed with specific wax. The sealer is part of the finish, not optional.

In depth

Decorative finishes in Málaga: microcement, Venetian stucco and continuous coatings

Continuous decorative finishes have moved in recent years from being a niche option to becoming the preferred choice for contemporary renovation on the Costa del Sol. Microcement lets you finish floor, walls and worktop with the same material and no visible joints, Venetian stucco revives a traditional technique with a gloss impossible to replicate with paint, and sprayed mortars add texture and personalisation. The three share one trait: they are not paint, not plasterboard and not painter work — they are specific trades with their own execution.

Substrate preparation represents between 40% and 60% of total application time and is the variable that decides the lifespan of the finish. A substrate with active moisture causes blisters and detachment within weeks; one with unevenness amplifies every imperfection under raking light; a poorly primed substrate triggers cracks running across the whole surface. For that reason, before applying, we systematically verify humidity with a hygrometer, flatness with a straight edge, room ventilation and sequencing with the previous trades.

In Málaga bathrooms and kitchens, the specific wet-area microcement range, sealed with polyurethane resin, is a very demanded option to avoid joints and achieve visual continuity. For flush-floor showers we apply a prior waterproofing membrane (Schlüter type or similar) before the microcement. In the restoration of traditional homes with old walls we prefer breathable finishes (lime) over resin-sealed ones, because old walls need to release ambient humidity to avoid salt accumulation.

Planning

Five decisions to close before applying the finish

A decorative finish depends as much on the substrate and the previous trades as on the chosen material. Reviewing these questions before ordering material avoids applying over a substrate that will doom the result in the short term.

humidity_mid
Substrate damp diagnosis
Check that wall or floor show no capillary damp, condensation or leak. Applying microcement or stucco on a substrate with active damp causes blisters, detachment and loss of the finish within weeks.
straighten
Real levelling of wall or floor
Verify substrate flatness with a straight edge before ordering material. Microcement does not correct unevenness: a wall with 5 mm hollows requires prior filling or a levelling coat, not an extra layer of product.
air
Compatibility with ventilation
In rooms with poor air renewal or high ambient humidity (bathrooms without forced ventilation, small kitchens), some finishes are not suitable. The choice must consider the real hygrothermal regime of the room.
account_tree
Order with the rest of the trades
Fix when the finish enters the works programme: plasterboard mounted and filled, painting of the rest of surfaces, final floors protected. A wrong order forces touch-ups or damages the freshly applied finish.
palette
Physical sample on the substrate
Before approving colour and texture for the full surface, apply a sample on the real substrate (not on cardboard or photographs). The tone and sheen of microcement or stucco change with substrate and room light.
