Preguntas frecuentes sobre pintura limewash

Limewash is a mineral paint made from slaked lime, water and mineral pigments. The recipe is deliberately simple — no synthetic binders, plasticisers or fillers. It does not form a sealed film on the wall; it bonds with the surface chemically, so the wall keeps its natural, breathable character.

No. The name refers to the traditional practice of washing walls with lime, not to washability. Limewash is a mineral paint that reacts to moisture: wet or greasy hands can leave a mark that water and detergent will not remove. This is a property shared by all natural lime paints.

The cleanest repair is to repaint the whole wall from edge to edge. With soft, light shades you can repaint a wider area around the mark and blend the edges out with a dry brush. With dark colours or deeper damage, apply PrepCoat to the affected area first, let it dry fully, then paint.

There is hardly any smell — only a faint, natural scent of lime you notice up close. VOC levels are minimal, so painting in a closed room is safe for children, pets and allergy sufferers. You don't need to leave the house or set up special ventilation.

A deep, full matte with no sheen at all. The surface is smooth to the touch — the sense of depth comes from the play of colour across the wall, not from any physical texture in the coating.

Coverage is approx. 1 L / 15 m² per coat. Two coats are standard, so a 30 m² wall needs approx. 4 L. With light shades or a very absorbent surface, allow a little extra for a third coat to get full, even coverage.

One coat leaves sharp edges and uneven transitions. The second evens out the colour, softens the contrast with the primer and builds the soft depth Limewash is known for. Dark shades show a clear play of light after two coats; light shades often need two or three to cover the white primer without losing their natural character.

It is the soft, irregular movement between lighter and darker areas of the wall, most visible in raking light. The paint is semi-transparent: light passes through the pigment and reflects off the white primer, which gives the surface its depth. The greater the contrast between colour and primer, the more pronounced the effect.

Not always, and not in the same way. Light shades give a calm, subtle movement; dark shades a clear play of light and shadow. The clouds come from irregular hand application and the transparency of the pigment — they don't appear on their own regardless of technique.

With light colours the effect stays subtle whatever you do — too many coats will flatten it completely. With dark colours the contrast with the primer naturally strengthens it. For more depth, use a darker shade for the first coat and a lighter one for the second.

Keep adding coats until the wall is as even as you want — each one reduces contrast and smooths out irregularities. Light shades usually settle after 2–3 coats; dark shades may need 4 or more to look flat and uniform.

The key is having no pattern. Work the brush in random, crossing directions and vary the rhythm. Avoid deliberately “painting clouds” — the shapes will stay visible exactly as you drew them. Keep a similar loose style on the second coat. See the step-by-step tutorial.

At least 8 hours, ideally 12. The surface must be completely dry to the touch before the next coat; painting onto a damp layer leads to weak adhesion and uneven coverage.

Not in normal daily use. Once dry, the coating is stable and does not transfer to fabric. Hard rubbing with a firm object can lift the top layer of lime — this is normal for a mineral paint, not a defect.

Yes — many of our clients do. Limewash gives a room a soft, enveloping light, and carrying the same shade onto the ceiling makes the space feel calm and continuous. If you'd like a subtle shift in tone, we can adjust the pigment slightly for the ceiling.

Yes — living rooms, bedrooms, hallways, studies. Where walls meet moisture or frequent touch (bathrooms, kitchens, around door handles) we recommend a protective sealer. In ordinary living spaces it isn't needed.

Yes. We mix colours from RAL and NCS references, match shades from photos or samples, and adjust existing colours. Colour advice on WhatsApp is free — just describe what you have in mind or send us your inspiration.

No. Wet, the colour looks darker; as it dries the lime lightens and the finish turns fully matte. Judge the colour only once the wall is completely dry — a Tester 250 ml from our samples is the easiest way to see it on your own wall.

It evens out the absorbency of the wall, improves adhesion and stabilises the surface. Limewash then soaks in evenly and forms a durable, consistent coating. Without a primer the paint can dry patchily or hold less well.

PrepCoat is a mineral primer developed by ZUBRA COLORS specifically for Limewash. Every colour test, consultation and sample we make is done on PrepCoat — which is why it is the only primer we can guarantee a predictable result and a durable finish with. We don't test third-party primers, because each behaves differently. Find it in PrepCoat & Sealer.

PrepCoat adheres well to gypsum plaster, cement-lime plaster and existing coatings — latex, ceramic and acrylic paints. It does not fill cracks or pores, so small irregularities stay visible, which usually adds to the natural character of Limewash.

No. If you want a perfectly level surface you can skim the wall, but neither the finish nor the durability of the paint depends on it. Try a simple test: PrepCoat plus a Limewash tester directly on your wall — if you like what you see, paint without extra layers.

Roller, brush or spray — each gives a correct result. We prefer a brush used in loose, crossing strokes: it adds a little texture that enriches the final Limewash effect. Spray and roller give a smoother, more uniform base.

Not by default. On a dark wall, apply it undiluted to cover the old colour well. On a light wall you can add 10–20% water so it spreads more easily. If the old colour still shows through once dry, apply a second coat rather than thinning the first.

Approx. 1 L / 15 m² per coat, much like the paint. Very porous or dry walls absorb more, so allow a little extra.

Minimum 6 hours, recommended 8–12, ideally 24. The primer should be dry not only on the surface but right through — the better it has set, the stronger the base for Limewash.

From light to dark, you can paint Limewash straight over the existing coat. From dark to light, apply PrepCoat first to neutralise the background. Going back to conventional paint, PrepCoat works as a transition layer and improves adhesion of the new paint.

It may, but we can't guarantee it. Each primer has its own absorbency and adhesion, and that directly shapes how Limewash behaves. If you want to use another product, test it on a small area and judge the result before painting the whole wall.

No — it isn't a repair product. PrepCoat stabilises absorbency and colour but does not fill gaps or cracks. Fill any damage with a filler before priming.

The surface must be clean, dry and sound. Remove dust, grease and any loose flakes of old paint. Lightly key glossy surfaces to improve adhesion. A well-prepared wall is the basis of a long-lasting finish.

Hidden doors prepared like a wall — yes. For furniture, MDF or laminate, apply a dedicated adhesion primer first, then PrepCoat and Limewash paint.

A wide wall brush. It lets you work loosely and in crossing strokes, which builds the natural, irregular look typical of lime paint. Our ZUBRA brush is matched to Limewash — its width and bristles were chosen for this product. See Tools.

A roller isn't recommended for the paint itself — it pushes the finish towards an ordinary acrylic look and loses the natural irregularity. Spraying is fine only for the primer, and only with the right equipment and experience. Always apply Limewash paint with a brush.

No. Use a separate brush for each stage. Even a well-washed brush can carry traces of the previous product, which affects the consistency and adhesion of the next layer. Keep one brush for PrepCoat and another for Limewash.

We chose it for mineral paints: soft, flexible bristles hold lime paint well and spread it evenly. The width suits both fine detail and large walls. We built it to be affordable while staying matched to ZUBRA products.

A double brush has two paint compartments, so you can apply two shades at once — for example a light and a darker tone on the same wall. It is used for strong accent walls. The result is intense and contrasting, but the technique takes practice, more time and more paint.

Not every painter. Working with two colours at once takes a feel for lime paint and some experience. Before a large wall, always try a small area first or talk the project through with us. In most interiors, a standard brush and two testers are all you need.

Yes. The standard ZUBRA wall brush covers most projects, but if you're working on very large surfaces or have specific needs, write to us and we'll suggest the right size.

No — the protective sealer is optional. Limewash shows its matte finish and depth best without one. We use it only where a wall is genuinely exposed to moisture or heavy contact.

Mainly where the wall meets moisture — bathrooms, kitchens, the area above a sink. Second, where it is touched a lot, such as hidden door frames or walls in narrow corridors. In a living room or bedroom it is usually unnecessary.

Not at all. It is a conscious choice that depends on the room. Leave it out in dry, low-traffic spaces and the wall keeps its fully natural character.

Yes. Any sealer — even one labelled matte — slightly darkens the colour and can add 5–10% sheen. That is why we don't recommend it where you want a raw, mineral matte.

Definitely. We offer sealer testers — apply one to a small patch and check the change in colour and sheen once dry. Better to see it on a few square centimetres than regret it across a whole wall.

Partly. It forms a thin protective layer, but it doesn't make the wall scrub-resistant. Heavy cleaning can remove the sealer along with some of the paint.

Gently — a soft, slightly damp sponge, no harsh cleaners and no scrubbing. Strong rubbing can wear through the protective layer to the paint beneath.

It forms a thin film on the surface of the lime coating rather than penetrating deep into it. That makes it straightforward to remove if you later refresh or repaint the wall.

For hidden doors, seal the whole wall so there is no difference in tone between sealed and unsealed areas. On furniture, MDF or laminate, start with a dedicated adhesion primer, then PrepCoat, the paint and finally the protective sealer.

A simple rule: dry rooms with light use — no. Damp or heavily used areas — worth considering. If you're unsure, get in touch and we'll look at the conditions together.
