Is Chalk Paint Waterproof?

Chalk paint is a popular choice for decorators, thanks to its distinctive finish and easy use. However, before using chalk paint on your outdoor furniture, you may be wondering if it is waterproof.

Paints for outdoor furniture should be waterproof to withstand poor weather conditions. Otherwise, they can become damaged after prolonged exposure to water.

Chalk paint is not waterproof, but you can still use it outdoors if you follow the proper precautions. So, here’s what you need to know about waterproofing chalk paint.

What Is Chalk Paint?

Chalk paint is water-based paint developed by the British artist Annie Sloan. Since then, manufacturers have developed similar formulas.

Chalk paint is valued due to its distinctive matte finish, which gives the paint its name. Chalk paint is versatile and can be applied to many different surfaces, often requiring less prep work than other paint.

What Are the Benefits of Chalk Paint?

Chalk paint is a popular choice among rustic and vintage lovers. It applies easily without needing sanding or priming, which is perfect for preserving the unique imperfections of vintage furniture.

Chalk paint is also very versatile. It can be applied to many different materials, from wood to plaster and even certain fabrics.

Chalk paint is also washable. It has a thick consistency and doesn’t drip. It also washes out of brushes with soap and warm water without the need for special paint cleaners.

Is Chalk Paint Suitable for the Outdoors?

Chalk paint is suitable for the outdoors. However, it is not waterproof, making it unsuitable for some outdoor uses. Most chalk paint is water-resistant and will withstand rainfall. However, surfaces where water can pool, such as tabletops, may need additional treatment.

How to Seal Chalk Paint for Outdoor Use

If you plan to use chalk paint outdoors, you may need to take a few additional steps to ensure that the paint job will last.

First, choose a suitable sealant. There are different types of sealants, depending on your purposes. If you are worried about rain, apply a multipurpose sealant that protects from all weather. If you are painting a horizontal surface that needs to withstand lots of wear, use a lacquer.

Once the chalk paint is dry, apply sealant using a brush or a spray bottle. Be sure to cover all of the surfaces generously.

Finally, wait for the sealant to dry. This can sometimes take a day or several days. Before starting painting, be sure that you will have the right weather while your item dries, as additional rain could affect the drying process.

Conclusion

Chalk paint is popular thanks to how easy it is to use and its distinctive finish. DIY decorators like to use it for a vintage patina on furniture, including outdoor pieces such as patio tables and chairs.

Chalk paint is not waterproof, but it is water-resistant, which is usually enough to protect outdoor furniture.
