To make sure renovation plaster bonds properly, you need the right primer. The best choice under ZUBRA COLORS renovation plaster is a deep-penetrating primer, which gives a stable, durable base, strengthens the substrate and improves adhesion.

Types of primer for renovation plaster

• Deep-penetrating primer: for absorbent substrates such as brick, concrete or old plaster. It soaks deep into the wall, strengthening it and improving the adhesion of the renovation plaster.
• Silicate primer: ideal for mineral substrates, especially when renovating historic buildings. It is vapour-permeable, so it supports the natural ‘breathing’ of the walls.
• Lime primer: recommended for lime plasters or renovation plasters based on lime putty. It supports the vapour permeability of the plaster and protects walls from moisture.

Do you need to prime walls before applying renovation plaster?

Yes – priming is a key step. Primer improves the adhesion of the plaster, reduces the absorbency of the substrate and gives an even surface, which makes the plaster easier to apply and more durable.

How long after priming can you apply plaster?

Drying time depends on the type of primer and the weather. Usually you can start plastering about 4–6 hours after priming, but in high humidity or low temperatures this can take longer.

Summary

For the best renovation results with a renovation plaster such as ZUBRA COLORS, always use a primer suited to the substrate. The right primer strengthens adhesion, extends the life of the plaster and improves its protective properties, giving a long-lasting result.

ZUBRA COLORS renovation plaster – modern technology for renovation

ZUBRA COLORS renovation plaster is a high-quality building material developed for renovating old buildings, façades and interior walls exposed to moisture. Its main ingredient is lime putty, which gives excellent vapour permeability and lets the walls ‘breathe’.

Benefits of ZUBRA COLORS renovation plaster

• High vapour permeability: the plaster lets moisture escape from the wall, preventing it from building up in the structure and protecting against mould and fungi.
• Resistance to damp and mould: thanks to the alkaline nature of lime, the plaster acts as a natural barrier against micro-organisms such as mould and bacteria.
• Excellent adhesion: it bonds to a wide range of substrates – concrete, brick and older plaster – making it a versatile renovation solution.
• Eco-friendly composition: the plaster is safe for health and the environment and contains no toxic substances such as lead or chromium.
• Durability and crack resistance: anti-shrinkage properties prevent micro-cracks as it dries, so it lasts for years.

Where to use ZUBRA COLORS renovation plaster

• Historic buildings: ideal where the natural vapour permeability of the walls must be preserved.
• Surfaces exposed to moisture: cellars, bathrooms and external façades, protecting walls from damp damage.
• New builds: also suitable for new buildings where high vapour permeability and an attractive finish are needed.
