 How to Pick the Right Product for Sealing Painted Wood

Do you want to protect your wood furniture from the elements? If you need to paint outdoor furniture, then sealing your work is essential. The right sealant can protect it from moisture and stains.

If you’ve been searching for a way to waterproof your outdoor paints, then you’ve come to the right place. This guide will help you choose the right product for your project.

Why You Should Use a Sealant

Exterior paints are designed to be waterproof and resistant to extreme weather conditions. Although many painted finishes last for decades without a sealant, other surfaces require it to prevent chipping and fading. Be careful, though. If you need to seal a painted surface, you should use a product that is compatible with the paint used.

How to Choose the Right Sealant

Sealants serve a variety of functions depending on the material and surface application. Here’s what to keep in mind when choosing one:

Solvent-Based Polyurethane Sealants

Solvent-based polyurethanes are more effective at sealing wood because they produce a stronger film. This product is a good choice when working with oil-based paints.

Water-Based Polyurethane Sealants

Water-based polyurethane is the best alternative for latex and acrylic finishes. It’s more environmentally friendly than solvent-based sealants.

Polycrylic Sealants

Although they work well with flat latex paints, they won’t bond as well with oil-based paint solutions. Some people prefer them because they are less toxic, but this sometimes can result in a shorter lifespan and create adhesion issues.

Paint and Sealer Product Combination

This revolutionary product combines a powerful sealant with paint to create a coating that protects the wood from the weather and the elements without needing additional coats.

  • Prepare the Surface: Ensure the surface is dry. Sand lightly to level any rough spots. Wipe with a tack cloth.
  • Prepare the Solution: Mix up the sealant by stirring thoroughly with a long, clean stick. Don’t stir too hard or you’ll introduce air bubbles into the fluid.
  • Apply the Sealant: Apply the paint in a thin, even coat, allowing it to dry completely before polishing. While painting, if you see any bubbles or drips, smooth them out using the edge of the brush.
  • Prepare the Surface Again: Allow the surface to dry thoroughly and sand very lightly. Dust away with a cloth.
  • Apply Final Coat: Apply a second coat and allow it to dry to achieve a nice finish.
