How to Make Chalk Paint Waterproof with the Proper Methods

Over several years, the popularity of varieties of chalk paint has steadily increased with the passing month as more people discover just how flexible it truly is.

Because individuals are discovering new methods to use chalk paint on other surfaces, you have seen an increase in the number of people trying to inquire how to make chalk paint waterproof.

Is chalk paint water resistant?

Although companies employ various formulations for their product, chalk paint is generally water-resistant, not waterproof.

The efficacy of this water-resistant protection will vary depending on where you live. Some people find it adequate, while others find it completely unsuitable.

For example, if you live in a warm climate with only a few weeks of light rain, you should be safe using chalk paint on your outside furniture without any additional protection.

If you are in a colder climate with constant rain all year or most months each year, you will put an additional coat on top of chalk paint to protect it from the weather.

Because of the character of chalk paint, it is quite difficult for producers to add any substance to the paint to ensure that it is naturally waterproof since it tends to modify the consistency.

Using an acrylic coating to waterproof chalk paint

The quickest and cheapest way to waterproof chalk paint is to apply an acrylic sealant over the top of the paint’s surface once it has dried.

Although these solutions provide excellent waterproof protection for the paint, they effectively build a layer over it, removing its unique feel.

This can work in favor depending on the chalk paint you choose, as it is usual for this paint to transfer to clothing when someone sits on chalk-painted chairs, for example.

You can normally apply a single layer of sealants over your paint, but most brands require at least two coats. Therefore, you must read the specific instructions and requirements on the label.

Spray acrylics, in our opinion, are considerably easier to utilize, especially on furniture with various angles that need to be protected.

Wait until the chalk paint is cured before applying the waterproof coating, and then hold the can 30cm from the surface. Spray an equal coat of paint over it.

Using wax to waterproof chalk paint

However, if you buy chalk paint from the local store, you can typically acquire the wax for a very low price if you buy it in large quantities.

The benefit of wax is that it provides superior all-around protection, including heat and UV protection, which acrylic sealing cannot usually provide.

Many who claim that their wax protects the chalk paint from water live in warmer climates with plenty of direct sunlight all year.

Although certain wax topcoats may be applied with a brush, we prefer spray-based products since they are faster and easier to apply. You hold the canister roughly 30cm from dried chalk paint and spray an even layer over it.

Polyurethane waterproofing for chalk paint

We normally do not advocate it since it is, in our view, the poorest technique of waterproofing the chalk paint, with any of the solutions above being a better choice for most individuals.

The polyurethane materials, like the acrylic sealant products, create a barrier on top of the paint, preventing the flaky chalk from migrating to garments when touched.

Although there are spray-based, they tend to function badly; therefore, we recommend that you choose a product that is applied with a brush. It can perform better despite being more difficult and time-consuming to try.

Wait until the chalk paint is completely dry before adding any product with a brush in a thin layer on top of it.

Why should you use chalk paint?

Furniture is frequently painted with chalk paint. It may be used to add texture and thin down for a smoother surface. You can simply make a distressed effect on the furniture’s surface to give it an old-world charm.

You are not, however, restricted to furnishings. Other applications include patio, flooring, and even entire houses. Because of the benefits, many people use chalk paint.

It does not need to be primed or sanded before being applied.

Because of its thick solvent, it drops less. Brushes and tools may be cleaned with water and soap. It is not necessary to strip furniture before painting it.

It may be used on almost any surface, including wood, concrete, metal, and brick.

Can you use chalk paint for your outdoor furniture?

You are fortunate if you intend to refinish furniture without removing the original paint. Chalk paint dries quickly and may be used on any outdoor furniture with no danger of fading.

Whether you varnish or seal the surface depends on its objective. If there is a chance that water might collect on the surface, it is better to add the varnish.

Because water will flow off the home if you paint it, you do not require a lacquer.

Also, to avoid water damage, cover all sides of a piece. If the underside of furniture is not painted, it is vulnerable to moisture damage.

The best topcoats for chalk paint

Polycrylic is closely related to polyurethane. It is necessary to sand between coatings. It does not have some risk of yellowing as polyurethane does.

The most common approach to seal this paint is using wax. It is tough and weather resistant. However, you should touch the coat as the wax peels off over time.

Next, the glaze will add some distinctive coloration and protection. The glaze is best kept for ornamental objects that will not see much use.

Varnish is the most traditional and time-tested method of waterproofing furniture. Varnish cannot be topped if you are willing to acquire new abilities and put in some effort when sealing and waterproofing this paint.
