Sealing a wood panel before painting offers numerous benefits, including creating a smooth surface and protecting the wood. In this post, we'll delve into why sealing is crucial, provide a step-by-step guide on how to seal a wood panel, and recommend a top-notch sealer for your artistic endeavors. Let's get started!

The Importance of Sealing a Wood Panel

Why Seal a Wood Panel?

Protects wood from the natural chemicals that can degrade a painting over time
Creates a barrier and prevents paint absorption into the wood pores
Ensures a more even and stable surface for applying the topcoat
Guards against warping and damage to the wood panel

Step-by-Step Guide: How to Seal a Wood Panel

Step 1: Prepare the Wood Panel

Clean the panel thoroughly, removing any dust or particles
If necessary, lightly sand the wood to open up the pores (Trekell panels come pre-sanded)

Step 2: Position the Wood Panel

Lay the panel flat on a surface
Optional: Prop it up on all four corners using wood props for easier application

Step 3: Apply the Sealant

Use a roller or brush to apply a light layer of sealant
Consider sealing both the front and back surfaces (we recommend sealing only the front and back of our panels)

Step 4: Allow the Sealer to Penetrate and Dry

Let the sealer seep into the wood panel and allow it to dry

Step 5: Lightly Sand and Remove Debris

Gently sand the surface and use a cloth or duster to wipe away any remaining debris

Step 6: Apply a Second Coat (Optional)

For extra protection, apply a second coat of sealant
Once dry, give the surface a final sand before applying your desired finish (paint directly onto the sealant or prime with gesso, oil ground, watercolor ground, etc.)
