The types of sealants you can use for chalk paint are as follows:

  1. Wax
  2. Polyurethane
  3. Varnish
  • Wax

Chalk paint is often sealed with wax because it gives a natural, matte finish and is easy to apply. It is available in both clear and other color options and can be buffed to a shine. The downside of wax is that it can smudge easily and may need to be reapplied frequently.

  • Polyurethane

People often ask me, “How do you seal chalk paint permanently?”

The best way to finish chalk paint projects is to seal them with polyurethane. This is because it is a synthetic sealant that provides a durable, easy-to-use, moisture-resistant finish. The finish can be matte or glossy. If you want to paint over light-colored paint, don’t use polyurethane.

  • Varnish

You can get it in both oil-based and water-based forms with a clear, protective finish. It offers a durable, moisture-resistant finish in matte and glossy versions. In spite of this, varnish can be yellow with time and can be difficult to apply.

Step: 1. Prepare the Surface

The paint should be sealed on a clean, dry surface. It is important to let wet paint completely dry before painting. A smooth finish may be achieved by lightly sanding the surface after the paint has cured. Wipe the surface with a damp cloth to remove any dust or debris.

Step: 2. Apply the Sealant:

Sealants may need to be thinned with solvents depending on their type. You should follow the manufacturer’s instructions for working with the product. You can apply wax with a soft cloth or wax brush in a thin, even layer.

In contrast, use a brush or roller when applying polyurethane or varnish to ensure a thin, even layer. Make sure you work in small sections and overlap your brush strokes to avoid leaving brush marks.

Step: 3. Allow the Sealant to Dry

Allow the sealant to dry completely after it has been applied, as instructed by the manufacturer. You may have to wait several hours or even overnight for this to happen.

Step: 4. Sand the Surface

The sealant may need to be sanded after it has dried to remove brush marks. You can use fine-grit sandpaper and sand along the grain. Remove dust from the surface by wiping it with a damp cloth.

Step: 5. Apply a Second Coat

Applying a second coat of sealant depends on the level of protection you require and the final look you want. The second layer of wax can be applied the same way as the first one. On the other hand, for polyurethane or varnish, you will need to lightly sand the surface before applying the second coat.

Step: 6. Buff the Surface

With wax, use a soft cloth or a buffing machine to bring the surface to a shine. The paint will be protected and will have a professional finish as a result.

How Long After Chalk Paint Can You Seal?

What Happens If You Don’t Seal Chalk Paint?

Without sealing chalk paint, it may scratch and chip more easily, especially in high-traffic areas or on frequently used pieces. Sealing the paint will protect it and make it last longer.
