Best Sealer for Chalk Paint
There are many different types of sealers that you can use for chalk paint.
Here’s a summary of each of them, as well as the advantages and disadvantages of each:
Furniture wax is the most popular sealer for chalk paint. In fact, it’s the number one choice and is considered the gold standard for sealing chalk paint.
It comes in a paste, or semi-solid formula which is applied directly onto the surface using a dry, lint-free cloth. Afterwards, it should be buffed out and cleaned also using a lint-free cloth. Wax sealers dry to the touch fast, though they don’t cure for around 2 weeks, so any projects sealed with wax should be treated as gently as possible until it fully cures.
Wax sealers come in a variety of colors to match your project, and leave a soft sheen which isn’t too far from the actual antique-looking finish of chalk paint. Since it doesn’t alter the appearance of chalk paint much, this is usually the first option for most people. If wax is going to be used on high traffic surfaces such as chairs or table tops, wax sealant should be reapplied regularly.
Polyacrylic or polycrylic sealers are the water-based alternatives of polyurethane. However, there are also oil-based versions, but water-based is always best in the case of chalk paint because oil-based formulas tend to yellow. In addition, polyacrylic sealers come in liquid and spray versions.
Polyurethane sealers in clear are a great topcoat for chalk paint furniture. It has long-lasting power, so this is highly recommended for projects that are exposed to water often, or high traffic areas. Polyurethane sealers can be applied using a brush or spray, quickly and easily.
Though oils are usually used for sealing milk paint and not chalk paint, the correct type of oil will do a good job. Typically, high-quality natural wood oils are recommended such as coconut oil, hemp seed oil, and Danish oil. They are made from more natural ingredients so they are also less toxic for you and the environment.
Water-based glaze can be used to seal chalk paint projects. It’s easy to apply for as long as your chalk paint has completely dried for at least 24 hours, and then let it cure for 3-5 days. For the best results, it is recommended to finish it off with a polyurethane or polyacrylic top coat.
If you are after a rustic, antique look, use one coat of chalk paint followed by a glaze because it will have a subtle impact on the color. While glaze is easy to apply and dries quickly, it doesn’t offer as much protection as the previous sealers mention. Glaze is usually best reserved for projects that are decorative and won’t be exposed to much wear and tear.
Aside from these, there are also specialty sealers on the market that are made specifically for chalk paint projects.
Given these choices, you can now choose the best sealer to use on chalk paint based on the advantages and disadvantages of each.
