Once you have decided on the kind of sealant you wish to apply, you will want to follow the simple process outlined in this article in order to ensure that your item is appropriately sealed.
In the following, you will learn about different kinds of sealant and how to apply them to wood surfaces.
How To Seal Acrylic Paint on Wood
After painting with acrylic, it’s important to seal your wood surface in order to protect the paint from chipping, peeling, and damage from exposure to the elements and common wear and tear.
When applying liquid sealant, make sure that you are administering a thin coat with smooth, even brush strokes.
If you are using a spray sealant, make sure that you spray evenly and horizontally from the same distance throughout the application process.
Sealant can take some time to dry, so be sure to allow several hours to several days time to pass after applying sealant before touching or using the painted wooden object.
Apply a Polycrylic Finish
Polycrylic finish is a low odor, nonflammable, protective topcoat that can be applied over bare wood or oil or water-based paints, making it a great choice for use on wooden projects painted with acrylic paints.
Recommended Polycrylic Finish: Minwax Clear

Miniwax Clear Polycrylic Finish is a clear wood finish that is water based, making cleanup of accidental spills or drips fast and easy.
It is a quick-drying finish, meaning that you can apply a second coat in as little as 2 hours after applying the first coat. To use, simply brush a thin, even coat over completely dry paint.
Apply Varnish
Varnish is a transparent protective coating that dries clear and hard. Varnish can effectively be applied to numerous materials, including wood.
Recommended Varnish: Liquitex
- Archival; Permanent; Non-Removable; Gloss finish
- Lightweight, non-toxic; Dries to a non-tacky, hard, flexible surface; Non-yellowing and...
Liquitex Varnish is a varnish that comes in various finishes. The high-gloss version is the perfect choice for projects that require a little extra shine, while the matte version can give your project a duller sheen.
Liquitex is a permanent, water-resistant varnish, making it a great choice for both indoor and outdoor projects.
To seal your project with Liquitex Varnish, first make sure that the painted surface is completely dry.
Depending on the thickness of the layers of paint that you applied, this could take anywhere from 72 hours to 2 weeks.
Next, you will want to gently stir the varnish. Then, using a broad brush, apply long, even strokes in a horizontal direction over the painted surface.
The thinner the layer, the more quickly it will dry, and the better it will look. Once you have applied the first coat, wait at least 3 hours to apply the second coat.
Apply Mod Podge
Mod Podge is a decoupage medium that can be used as a glue, sealant, and varnish. It can be used for a wide variety of arts and crafts projects, including as a sealant for wood.

Although Mod Podge may look milky when applying, it does tend to dry clear.
The Mod Podge Complete Kit also comes with four foam brushes. To use, simply smooth even layers of Mod Podge over the painted surface using the foam brushes.
Allow each layer to dry for at least 15 minutes before applying the next.
