How to Easily Protect Your Home with Waterproof Plasterboard

Waterproofing plaster can be a simple process if done properly. Plaster is a commonly used material both indoors and outdoors, with differing qualities requiring different methods of water protection. Exterior cement plaster is extremely strong and rarely requires any further care, whereas interior plaster needs to be protected against moisture and humidity. Additionally, even small leaks can cause significant water damage.

Here are the steps to waterproof interior plaster:

1. Before painting the wall, apply one coat of heavy-duty primer. Primers create a beautiful finish, as well as a foundation layer for your paint barrier.

2. Finish with a layer of paint. Interior paint will work, but for added protection, use a high-quality exterior paint, which is specifically made to withstand the elements.

3. If you prefer not to paint, you can apply a light coat of linseed oil. Sand the plaster to a smooth finish before applying the oil. This will allow it to absorb more efficiently. Use a high-quality brush with natural bristles to apply the oil evenly.

4. This should result in a wall that doesn’t look greasy. Once the oil has had a few hours to settle, you won’t be able to tell it was treated at all.

WARNING: Linseed oil is highly flammable and paintbrushes or rags soaked in it can suddenly catch fire when exposed to heat. Therefore, you should place any used tools in water containers once you’re finished.

Waterproofing plaster is a straightforward process that can be done without having to hire a professional. Furthermore, good water protection can help protect your walls from water damage. Therefore, make sure you follow the steps outlined here to ensure that your plaster is properly waterproofed.
