How to Fix Bubbling on Wood

Bubbling on hardwood may be caused by improper oil-based finish application. Bubbling is also a common problem in glued-on veneers, thin sheets applied to the surface of inexpensive furniture to create the illusion of solid wood. You can fix either of these common wood bubbling problems with easily attainable hardware supplies.

Instructions

  1. Fix Bubbling on Veneers

    • 1

      Place a piece of fabric over the affected area and iron over it on medium-high heat to soften glue that could be causing bubbles.

    • 2

      Place a damp cloth over the damaged area if the bubbles remain. Allow the cloth to sit for five minutes before removing it, then wipe away excess with a dry cloth.

    • 3

      Fill a glue injection with a solution of 85 percent glue and 15 percent water. Make a small slit in each of the veneer bubbles, using a utility knife.

    • 4

      Inject glue into the holes you made. With gloved hands, squeeze out any excess glue and wipe it away with a damp cloth.

    • 5

      Place fabric over the bubbled area and run over it with an iron set on high heat.

    Fix Bubbling on Wood Finish

    • 6

      Coat the wood surface with lacquer remover to dissolve the bubbling finish. Wait for the amount of time specified on the lacquer remover’s package, then scrape it away with a scraping tool. Rinse the wood and allow it to dry before proceeding.

    • 7

      Apply a thin coat of water-based finish to the wood surface, using a paint roller to cover large areas and a paintbrush to cut into corners or paint small and detailed areas. Alternately, use a spray finish.

    • 8

      Allow the finish to dry for an hour before ventilating the area. Finish can bubble when disturbed by drafts during the drying process.
