Durability of Limewash Paint

What to Expect from Limewash Paint Over Time

Limewash Paint on Render: The Complete Preparation & Application Guide

Render is a type of plaster or coating applied to interior or exterior walls to create a smooth or textured finish, usually rougher than traditional plaster. It’s ideal for limewashing because its porous surface absorbs the limewash effectively, allowing breathability and preserving the wall’s natural qualities. No undercoat or top coat sealer is required, making the process quick and simple.

  • limewash internal render walls
  • limewash external render walls

Limewash Paint Durabilty FAQs

How long will Bauwerk limewash paints last in comparison to other paints?

You can expect a similar life expectancy to that of other quality brand paints provided that the paint is applied in the manner recommended by Bauwerk.

The pigments used in Bauwerk Limewash paints are mineral based, colourfast and UV stable. This means that our colours are not affected by the sun’s Ultra Violet rays (which can cause paints to fade). Our paints have been fully tested in the extreme temperatures of Australia and the Middle East.

Our limewash is a beautiful, natural paint choice, found in new and historic buildings all over the world. We are proud of the natural qualities of our paints. Unlike many paint companies that promise a perfect and long-lasting finish by incorporating harmful PFAS, also known as ‘forever chemicals’, we remained committed to an environmentally friendly approach.


When painting Bauwerk Limewash Paint over porous materials such as render or brick, our paints are exceptionally durable because they are absorbed into the wall surface. However, if you are painting over sealed or previously painted walls, it is essential to know that limewash isn’t as indestructible as more conventional, non-natural paints.

 

To improve durability and simplify application over sealed or previously painted interior walls, we have developed BAUWERK Prep Coat . Acting as an absorbent layer, Prep Coat facilitates limewash adhesion and can be applied easily by brush, roller, or sprayer. Like all surfaces subject to wear and tear, over time your limewashed walls may require maintenance. To maintain your walls, we recommend simply applying a light refresher coat of limewash. It is quick, easy and makes your walls more beautiful and durable with every layer.



We work with nature to make paints that are good for the environment including your home environment, many standard paints have a toxic mix of chemicals such as biocides, plastics and heavy metals to make them function as paints that stick to your wall, and make it possible to scrub them. With natural antibacterial qualities, our paints are suitable for a high-humidity environment. We have specially developed our BAUWERK Prep Coat as a bridge coat between standard paint and primers to make limewash more durable, and easy to apply. If your walls need a refresh, simply whoosh on another coat of limewash, it’s quick and easy, and it can be repainted anytime. Each coat makes it more durable and best of all more beautiful, every coat just enhances what is there.

Absolutely, limewash paint is ideal for raw masonry exteriors, like render, brick and cement materials, where it can be absorbed into the surface. The result is a breathable wall that is protected by the natural properties of the paint. Limewash paint does not blister or peel, making redecoration easy.

The pigments used in Bauwerk Limewash paints are mineral-based, colourfast and UV stable. This means that our colours are not affected by the sun’s Ultra Violet rays (which can cause paints to fade). Our paints have been fully tested in the extreme temperatures of Australia and the Middle East.

In addition to using it for building structures, limewash paint is great for garden walls and on planters and plant pots too!

The most durable surface materials for limewash paints is a moderately absorbing render.

The render will allow the limewash to penetrate well below the surface where the paint can form millions of micro crystals. This process is also known as fossilisation whereby the lime wash reverts back to its original form of calcium carbonate (lime stone). It does so by the simple action of re-absorbing athmospheric CO2.

Renders can be cement based (those are the most hard wearing surfaces) or lime / clay based. But also natural stones can be the basis for a hard wearing lime wash finish, particularly lime stone.

Modern factory blended renders can also be purchased as thin coat renders. Those contain special additives that allow them to bond to a variety of surfaces, and are applied in thicknesses of only 3-5mm. That is very useful when you want to re-surface an older existing render or want to tie in a drywall construction with an existing masonry wall.
