When it comes to the question of whether limewash is waterproof, the answer is no. Limewash isn’t naturally completely waterproof. However, there’s a solution to increase water resistance. By applying a lime sealant over a limewash finish, you can add an extra layer of protection and make the lime walls easily wipeable.
Can You Waterproof Limewash?
Limewash, a traditional paint made from slaked lime, has been used for centuries to coat and protect surfaces such as plaster and masonry. However, it’s important to note that limewash isn’t naturally completely waterproof. It’s a breathable finish that allows moisture to pass through, preventing the trapping of moisture within the walls, which can lead to damage over time.
That being said, there are options to enhance the water resistance of limewash. One such option is applying a lime sealant over the limewash finish. A lime sealant acts as a protective layer on top of the limewash, adding an additional level of water resistance. This helps to repel water and make the lime walls more easily wipeable, preventing water damage and stains.
When choosing a lime sealant, it’s important to select a product specifically designed for use with limewash. These sealants are formulated to be compatible with lime-based paints and ensure optimal adhesion and performance.
Applying a lime sealant is a relatively simple process. The limewash should be allowed to fully cure before applying the sealant, which usually takes around two to three weeks. The sealant can be applied using a brush or roller, following the manufacturers instructions for the specific product. It’s important to apply an even coat and allow it to dry completely before applying additional coats, if necessary.
It’s still important to take precautions to prevent excessive exposure to moisture or standing water. Regular maintenance and inspections are key to ensuring the longevity of the limewash finish.
This additional layer helps to repel water and make the walls easily wipeable.
Tips for Properly Curing Limewash Before Applying a Sealant
Curing limewash before applying a sealant is an important step to ensure proper adhesion and longevity of the sealant. Here are some tips to follow for a successful curing process:
1. Allow sufficient drying time: Limewash typically takes several days to fully dry, depending on factors like temperature and humidity. Patience is key to avoid trapping moisture beneath the sealant.
2. Avoid direct sunlight: Direct sunlight can cause the limewash to dry too quickly, leading to uneven curing and potential cracking. Choose a shaded area or use protective coverings if needed.
3. Maintain proper ventilation: Good airflow aids in the curing process by promoting evaporation. Open windows or use fans to encourage air circulation, especially in enclosed spaces.
4. Be wary of moisture sources: Avoid exposing the limewash to excess moisture during the curing period. Be cautious when cleaning surfaces nearby and ensure there are no leaks or excessive humidity in the area.
5. Check for dryness: To determine if the limewash is adequately cured, touch a small hidden area or use a moisture meter. If the surface feels dry and readings are within an acceptable range, it’s ready for sealant application.
Following these guidelines will help you achieve a well-cured limewash surface, providing a solid foundation for sealing and enhancing the appearance of your project.

However, there are other methods to make limewash waterproof that don’t involve using linseed oil. By incorporating ingredients like beeswax or acrylic additives into the mixture, you can enhance it’s water-resistance properties. These additives create a protective barrier on the surface, preventing water from penetrating. In the following sections, we will explore different techniques to make limewash waterproof and discuss the application process in more detail.
How Do You Make Limewash Waterproof?
Linseed oil is a natural oil derived from flax seeds, and it’s long been used as a wood finish due to it’s water-repelling properties. By adding just a small amount of linseed oil to your limewash mixture, you can enhance it’s waterproofing abilities.
To make limewash waterproof, start by mixing a batch of traditional lime putty. Lime putty is made by slaking quicklime with water and allowing it to sit and mature for several months.
It’s important to note that you should only add a very small amount – no more than 1% of the total mixture. Adding too much linseed oil can negatively affect the appearance and durability of the limewash.
You can use a whisk or a paint mixer attachment on a drill to achieve a consistent mixture.
Use a brush or a roller to evenly distribute the limewash, taking care to cover the entire surface.
After the limewash has been applied, allow it to dry completely. Once dry, you can assess the waterproofing capabilities of the limewash.
If you require further waterproofing or want to ensure the limewash doesn’t wash off, you may consider applying a sealant over the top. There are various sealant options available, such as clear masonry sealers or water-repellent coatings, that can provide an extra layer of protection to your limewashed surface.
When it comes to sealing limewash paint, plaster, tadelakt, stucco, and stone surfaces, Color Atelier Sealer is the ideal choice. This clear and protective topcoat provides a perfect finishing touch, ensuring longevity and durability for the beautiful surfaces you’ve created.
