How To Fix Bubbles In Hardwood Floor Finish❓

Bubbles in your beautiful hardwood floor finish can be an eyesore, but don’t despair! Depending on the severity, there are ways to fix them and achieve a smooth, flawless surface through the right tools, techniques, and a little patience.

This article will guide you through identifying the type of bubbles, its causes, and how to effectively fix bubbles in hardwood floor finish, restoring your floors to their former glory. Before moving further, let’s have a look at:

How Hardwood Floor Bubble Up?

The clear liquid used for water-based polyurethane floor finish is much thinner than the one for solvent-based finish. When you shake, stir, or pour it, it often makes bubbles. Even though these bubbles usually disappear on their own, they might leave some behind. When you spread this finish on the floor with a paintbrush or pad, you can accidentally spread these bubbles too. Since water-based finishes dry fast, the bubbles may not have time to go away before the finish hardens. This can leave you with patches of bubbles on your floor, some fully formed and others only partly gone.

Causes Of Hardwood Floor Blistering

Before attempting to fix bubbles in the hardwood floor finish, it’s essential to identify the underlying cause to prevent recurrence. Some common causes of wood floor bubbling up include:

Moisture

Excess moisture in the wood or air can cause bubbles to form as the finish cures.

Contaminants

Dust, dirt, or other contaminants on the surface can interfere with the adhesion of the finish, leading to bubbles.

Improper Application

Applying the finish too thickly or too quickly can trap air, resulting in bubbles.

Product Issues

Using an incompatible or expired finish product can also contribute to bubble formation.

Materials Needed To Fix Bubbles In Wooden Floors

• Sandpaper (fine grit)
• Mineral spirits or denatured alcohol
• Clean, lint-free cloths
• Floor finish appropriate for your hardwood floors
• Foam brush or applicator pad
• Floor buffer (optional)
• Wax or polish (optional)

How Do You Fix Bubbles In Hardwood Flooring?

Given below is the detailed answer to “How do you get bubbles out of wood finish?”

Sand the Affected Area

Begin by sanding the area with bubbles using fine-grit sandpaper. This will help to remove the existing finish and any imperfections on the surface of the wood. Sand gently to avoid damaging the wood beneath the finish.

Clean the Surface

Once the area is sanded, vacuum it thoroughly to remove any dust, dirt, or debris. Use a clean, lint-free cloth dampened with mineral spirits or denatured alcohol to wipe the surface clean. Ensure the surface is completely dry before proceeding to the next step.

Apply the Finish

Stir the floor finish thoroughly to ensure it is well mixed. Using a foam brush or applicator pad, apply a thin, even coat of finish to the sanded area. Work in the direction of the wood grain to ensure proper coverage.

Feather Out the Edges

To blend the newly applied finish with the surrounding area, feather out the edges by lightly dragging the brush or applicator pad along the edges of the finish. This will help to prevent noticeable lines or differences in sheen once the finish dries.

Allow the Finish to Dry

Allow the newly applied finish to dry according to the manufacturer’s instructions. Avoid walking on the freshly finished area or placing any furniture on it until it is completely dry.

Buff the Surface (Optional)

If desired, you can use a floor buffer equipped with a buffing pad to buff the surface lightly. This will help to smooth out any imperfections and enhance the shine of the finish.

Apply Wax or Polish (Optional)

For added protection and shine, consider applying a layer of wax or polish to the entire floor surface once the finish has fully cured. Follow the manufacturer’s instructions for application and drying times.
