How to create the Limewash effect — a 4-step guide
Step 1: Primer (PrepCoat) — mandatory
Our ZUBRA COLORS PrepCoat is specially designed for Limewash and other water-based lime paints. It does two things at once:
- Increases adhesion (acts as a universal primer);
- Balances surface absorption so the paint can properly “soak into” the substrate — this is the key to achieving the Limewash effect.
How to choose the application method:
- White smooth surfaces → dilute PrepCoat with ~20% water.
- Dark walls / colored surfaces → do not dilute; cover completely to “neutralize” the underlying color. May need additional second layer of PrepCoat if the dark color still appears on the wall.
- Plasterboard with joint compound → apply 2 coats:first coat: ~20% water, to even out the different absorption levels of the board and the joint compound.second coat: undiluted. This will equalize the absorption differences between the board and the joint compound.
Tools: brush, roller, or spray.
Note on other primers: the Limewash effect depends 40% on the right primer. You can test other primers at your own risk — always make a small test with our paint on your wall first.
Step 2: Primer drying time
Wait at least 6–8 hours. Even if the surface feels “dry to the touch,” there may still be moisture inside. Painting too early can mix the layers and ruin the effect.
Step 3: Painting with Limewash paint
Use only a brush (a wall brush or our double Limewash brush). A roller won’t create the Limewash effect — it will look flat and lose the intended texture of the technique.
The paint is ready to use — do not dilute it.
Technique:
- Paint chaotically, spreading the paint across the wall.
- Don’t paint “cloud shapes” like in online tutorials — it’s easy to overdo it and lose the natural look.
- The standard is 2 coats (with a 6–8 hour break between each).
- 3 coats: recommended if you want smoother transitions or when using near-white (very light) shades where the primer might show through.
Why does the “cloud effect” appear?
Limewash is slightly transparent. The difference between the primer color and the paint color, combined with areas where more or less paint is applied with the brush, creates irregular, mineral-like transitions.
What will you see after the first coat?
- With darker or neutral colors, edges and streaks may appear sharp — that’s normal. They will even out after the second (or sometimes third) coat.
- With near-white colors, a third coat is sometimes needed because the light paint and white primer can create a flat appearance.
Working with two colors (options):
- Layered: 1st coat darker, 2nd coat lighter → subtle “show-through” and depth.
- Two colors on one brush: special effect; we recommend it mainly for a single accent wall, not for large surfaces (on big areas it can look too “handcrafted”).
Important: Before ordering full liters, get 250 ml testers and check the color, number of coats, and possible combination of two shades. It’s the only reliable way to see how your wall will “come to life.”
Step 4: Protective coating (optional)
Natural Limewash finish = no sealer:
- the surface is stable (doesn’t dust or stain your hands),
- retains a deep, mineral matte finish.
Downside: it’s not washable — stains are usually fixed by repainting a thin “patch.”
With protective matte sealer:
- Plus: higher resistance to dirt and moisture (e.g., around hidden doors or splash zones).
- Downsides: slightly darkens the color and changes the matte character; it’s a thin “film” that can be damaged by aggressive cleaning.
- For direct contact with water (e.g., showers), a two-component polyurethane sealer is required — a different category of protection.
Recommendation:
apply the sealer only where it’s truly needed. You can always consult us for advice on the right product and technique.
Additional tips
- Do not dilute the paint (it’s perfectly prepared for brush application).
- Use 250 ml testers before any larger order — this lets you check the color in your lighting and on your wall texture.
- Limewash paint is odorless and safe for households, children, and pets.
- If you really want to use a different primer than ours — make a test with Limewash on your wall before starting the full area.
