How to make chalk paint permanent?

Published in Chalk Paint Sealing 3 mins read

To make chalk paint durable and long-lasting for everyday use, you need to seal it.

Chalk paint is known for its matte, porous finish, which can be susceptible to marks and wear if left unsealed. Applying a protective topcoat makes the finish resistant to spills, stains, and general use, effectively making it more permanent for practical purposes.

Why Seal Chalk Paint?

Sealing is the crucial step that transforms chalk paint from a decorative finish into a functional one.

As stated in the reference: "Sealing Chalk Paint® with Wax or Lacquer will not only protect your finish, but help the colour last longer. It means you can use your item without worrying about leaving behind marks or taking the paint off when you clean it."

  • Protection: Guards against scuffs, scratches, and spills.
  • Durability: Allows the painted surface to withstand regular handling and cleaning.
  • Color Longevity: Helps maintain the vibrancy and depth of the paint color over time.

Sealing Methods

The most common and recommended ways to seal chalk paint, as indicated, are using wax or lacquer. The choice depends on the desired look and level of durability needed.

1. Sealing with Wax

Wax is a traditional sealant for chalk paint, offering a soft, matte finish and deepening the paint color slightly.

  • Application: Apply a thin, even layer of clear wax using a wax brush or lint-free cloth. Work it into the paint surface.
  • Buffing: After allowing the wax to set (check product instructions for timing, typically 20-30 minutes), buff the surface with a clean cloth to achieve a smooth finish and activate the protection.
  • Curing: Wax takes several days to fully cure and reach its maximum durability. Handle the item carefully during this time.
  • Durability: Suitable for moderate use surfaces like dressers, picture frames, and decorative items. Less ideal for high-traffic areas or surfaces exposed to water frequently.
  • Maintenance: May require occasional reapplication on high-wear areas.

2. Sealing with Lacquer

Lacquer (or varnish/topcoat) provides a more robust and water-resistant finish compared to wax, making it suitable for higher-wear surfaces.

  • Application: Apply thin coats using a brush or roller specifically designed for topcoats. Sand lightly between coats for a smoother finish if applying multiple layers (follow product instructions).
  • Drying & Curing: Lacquer typically dries to the touch quickly but requires several days to a week or more to fully cure, depending on the product and environmental conditions.
  • Durability: Offers excellent protection against water, stains, and heavy use. Ideal for tabletops, kitchen cabinets, or floors painted with chalk paint.
  • Finish: Available in various sheens, including matte, satin, and gloss.

Choosing between wax and lacquer depends on the piece of furniture or item being painted and how it will be used. Both methods, when applied correctly, create a sealed, protected surface that makes the chalk paint finish permanent for its intended use.
