How to Fix Warped Plywood Cabinet Doors

Table of Contents

It’s not uncommon for cabinet doors to warp over time. As the wood contracts, it can create gaps that are unsightly and sometimes difficult to use. This article will provide you with a few tips on how to fix warped plywood cabinet doors.

Sand down the high and low sides on both sides of your cabinet door.
Use a piece of wood glue to fill in any gaps that are still present.

Allow it to dry overnight.
The next day, using coarse sandpaper, smooth out rough edges as well as excess filler if needed on top of your plywood cabinet door.
Once you have sanded down the excess filler, apply a wood stain that matches your desired color to give it a fresh new look before replacing it with the original hinges on your doors, and enjoy once again.

Warping is a term used to describe when wood shrinks or swells in different directions. This often happens over time and results from humidity changes within the air around your home. Warping can also occur if you leave your cabinets exposed to water for long periods, such as during flooding or leaky pipes that drip into the cabinet.

Types of Warping

There are three types of warping:

Vertical – The door has a lean and gets taller on one side. If you open your cabinet doors, the inside will be uneven because the top is higher than the bottom. This type of warp can also happen if there is too much weight on the right or left-hand side as well as not being properly installed.

Horizontal – This type of warp is more common because it’s usually not noticed as much. One side will be higher than the other, but no gaps are showing. This warping can happen if your wood was cut too thick or thin for its application and also occurs due to improper installation by being off-kilter.
Diagonal – The door has a lean and gets shorter on one side. If you open your cabinet doors, the inside will be uneven because the top is taller than the bottom. This type of warp can also happen if there are too many hinges or not enough support under them as well as being improperly installed.

What Causes Warping of Plywood Cabinet Doors?

There are multiple reasons why your cabinet doors may begin to warp over time. Some of the most common causes include:

Exposing Plywood Doors to Water – If you’ve ever noticed that plywood shrinks when it is exposed to water, then this should come as no surprise.
Temperature Changes – If you’ve noticed your cabinet doors sticking or jamming, then it’s likely that they are warped and need to be fixed immediately.
Exposing Your Plywood Doors to Direct Sunlight – Over time, direct sunlight can cause wood to warp and distort because it causes the color of your cabinet doors to fade more quickly than they normally would.

2. Use Wood Glue to Fill in Gaps.

Once you’ve sanded down your plywood cabinet doors and fixed any high or low spots, it’s time to fill in any gaps that are still present on one side of your cabinet door.

Once you’ve applied enough wood glue into any gaps on your cabinet door, you can apply wood filler to help smooth out the dried glue. Spread a thin layer of the filler into all gaps and allow it to dry for about an hour before sanding down any rough edges that form as well as any excess filler on top of your plywood doors themselves.

4. Sand Down Filler.

Once your wood filler has dried, it’s time to sand down the excess with a coarse piece of sandpaper that was cut to fit your electric drill or sander attachment once again.

5. Apply Wood Stain for a Professional Look.
