Sealing Tempera Paint on Wood: A Comprehensive Guide

Protecting your tempera-painted wooden artwork with a suitable sealer can significantly enhance its longevity and durability. This article will guide you through the process of sealing tempera paint on wood, ensuring your artwork stays vibrant and sturdy for years to come.

Materials Needed

Tempera paint - already applied and dried CLEAR ACRYLIC SEALER - available in spray or brush-on form Sandpaper (optional for smoothing surfaces) Clean cloth - for dusting Paintbrush (if using a brush-on sealer)

Steps to Seal Tempera Paint

Ensure Complete Drying

Make sure the tempera paint is completely dry before applying any sealant. This can take several hours to a day, depending on the thickness of the paint and environmental conditions. Proper drying is crucial to prevent any adverse reactions with the sealer.

Prepare the Surface

If the wood surface is rough or has any imperfections, lightly sand it with fine-grit sandpaper to create a smooth surface. Wipe away any dust with a clean cloth to ensure a clean base for sealing.

Choose a Sealer

There are two main types of sealers available:

Spray Sealer - Provides an even coat, making it ideal for larger surfaces. Brush-On Sealer - Offers more control, particularly for detailed areas.

Apply the Sealer

Here are the specific application methods for each type of sealer:

Spray Sealer

Hold the can about 6 to 12 inches from the surface. Spray in light, even coats. Move in a sweeping motion to avoid drips. Allow each coat to dry for 15-30 minutes before applying the next.

Brush-On Sealer

Use a clean paintbrush to apply a thin layer of sealer over the painted area. Be gentle to avoid disturbing the tempera paint. Allow it to dry completely before applying additional coats.

Multiple Coats

To ensure maximum protection, especially if the item will be frequently handled or exposed to moisture, apply multiple coats of sealer. Allow each layer to dry completely before proceeding to the next coat.

Final Drying

After the final coat, give the sealed artwork at least 24 hours to fully cure. This allows the sealer to fully set and provides the best protection before using or displaying it.

Tips

Test the sealer on a small, inconspicuous area first to ensure it doesn’t react with the tempera paint. Consider the environment - if the artwork will be displayed outdoors or in a high-humidity area, opt for a sealer specifically designed for outdoor use.

By following these steps, you can effectively seal tempera paint on wood, preserving your artwork for a longer time and ensuring its vibrant colors and robust finish.
