Why and How You Should Seal a Wood Panel Before Painting

There are many benefits to sealing a wood panel before painting your piece. Create a smooth, even surface to your wood panel and protect it by sealing  before painting. In this post, we will highlight the importance of sealing a wood panel, how to seal a wood panel, and our top recommendation for a top-notch sealer. Let’s begin!

Why seal a wood panel?

Sealer protects wood materials and tends to be a glossy, non-absorbent substance that protects the wood surface by creating a barrier. Protect your wood panel by applying a sealant to it prior to painting. The natural chemicals that wood contains can break down a painting over time, but sealing protects wood from this. Sealants smooth the surface and provides an even exterior to wood. The paint will not be absorbed into the wood pores when sealer is applied so the topcoat will sit better on the surface. Applying paint without sealing may cause warping or other damage to your wood panel. 

How to seal a wood panel?

  • Clean off the wood panel ridding it of dust and other particles with a cloth or duster. Sanding of the wood may be required to open the pores of the wood. Trekell panels come pre-sanded so no extra sanding is required.
  • Lay the panel flat on a surface. It is not necessary, but you may want to prop it up on all four corners using wood props to help ease the application of sealer.
  • Apply a light layer of sealant to your wood panel with a roller or brush. Some artists cover all sides and corners of their wood panels, we only seal the front and back of our panels.
  • Let the sealer seep into your wood panel then dry.
  • Lightly sand the surface and use a cloth or duster to wipe away debris.
  • Apply a second coat to your wood panel for extra protection. Give one final sand, once dry, before applying your desired finish. Some artists paint directly onto the sealant so the wood grain shows through. Others prime with gesso, oil ground, watercolor ground, or adhere linen to the wood panel, etc., once the sealant has dried.
