How to Fix Warped Wood

Let’s start with identifying warped wood. What is warped wood? Warped wood is extremely common, and it’s simply when your furniture or floorboards have become uneven due to being either too wet or dried out far too quickly. This is usually caused by the humidity in the air; for example, one of the most typical ways warping can occur is when you take a wooden floorboard from somewhere where there’s extremely high humidity to another that has very low humidity if you don’t give that piece of wood enough time to adjust then it will warp drastically. If you see heavy bowing on your floor, this could also be caused by an above-ground swimming pool that leaves your house with a great increase and then allows the humidity in the air to drop dramatically, which causes it to shrink.

Another very common way of identifying warped wood is through checking if it has become uneven. If you have a piece of furniture or floorboard with multiple legs, then if one leg points down toward the floor more than the others, there’s a good chance that this may be caused by warped wood.

Why Does Wood Warp?

There are a few different reasons why wood will warp, and we’ll be going over the common ones below:

– Wood warping because it’s too wet. The most typical reason as to why your floorboards or furniture may become warped is if they have been soaked for an extended period of time, but it’s important to note that this can also happen if it’s dry wood and too much moisture is applied. Warping usually occurs when the wood doesn’t have enough time to adjust before it’s dried completely. For example, if you’re washing your floors with a lot of soap suds, then this should be enough warning that you need to wipe it all off within 30 minutes; otherwise, there’s a chance that your floorboards will warp.

Long Term Exposure to Heat and Humidity

If you have a piece of wood that has been stored in a damp room for a prolonged period of time, or worse still outside, then this may also be what causes it to warp. In most cases, if the humidity level drops from high to low again, it may not cause any problems, but there is always a chance that you could end up with warped floors or furniture if this is an issue. However, the safest way to avoid warping due to heat and humidity isn’t by moving your wood from one extreme condition to another. Instead, it’s better to slowly introduce your floorboards and furniture into the new conditions over a number of days so as not to shock them.

Prolonged Exposure to Humidity and Downpour

If you leave a piece of wood over the winter and it’s been outside for an extended period of time, then there is also a chance that it will warp; this is because when you get heavy rainstorms followed by the sun, the water doesn’t evaporate off quickly enough and causes your wood to become soaked. If you have wooden furniture or floorboards outside during our winter months, then it’s important that you take them in before the first frost and store them somewhere where they can dry out completely. Otherwise, there’s a good chance that they may warp.

How to Fix Warped Wood

There are some ways on how to fix warped wood, and we’ll be going through three different ways here:

– You can use steam to flatten the wood. This is one of the most common ways on how to fix warped wood. For this method, you will need your steam iron and a sheet of plywood that’s either larger or smaller than the warped piece that needs flattening.

– You can use weights to flatten it out again ( very important ). If you’re looking for an easier way on how to fix warped furniture, then this second method is probably more suitable for you, which involves simply sticking some heavy books onto your boards in order to pull them flat again. However, however, what you do make sure of is that these items are spread about evenly across the board so as not to cause any indentations when they dry out completely.

Does Wood Warp in Different Ways?

The most common type of wood warping is when it has become bowed or curved, but it can also become twisted too. This occurs mostly because the warp is usually made up of two different types of wood which are joined together to form one piece.

How to Identify Warped Floorboards

Warped floorboards are very unsightly, and if they’re in a room that sees a lot of traffic, then you may want to consider fixing them as soon as possible otherwise, you risk having people trip over them. Although warped floorboards are fairly easy to spot, there are some tell-tale signs that you should watch out for:

– If your floorboard looks uneven over its entire section. This doesn’t necessarily mean that it’s warped. It may also mean that you need to sand them down again in order for the finish to adhere correctly.

– If your floorboard has raised or sunken areas where the wood looks either darker or lighter than other parts of the board, then this means they’re warped.

It’s worth mentioning here that if your floors are bowing slightly due to humidity changes, then you can easily correct this by applying some pressure onto the high points using a block plane, thus forcing these areas back into shape. You will need to lightly plane both sides of your floorboards so as not to create grooves that run through them. Instead, just focus on removing small pieces from any high points, and you’ll see an improvement very quickly.

How Do You Fix Warped Wood?

Warped wood can be repaired very easily, and the only items that you will need are either a steam iron or some heavy books. You simply dampen the boards slightly so as they don’t burn, then clamp them together with your plywood on top of them. Then turn on your steam iron and leave it to sit on top of the boards for around 10 – 15 seconds before removing it and allowing everything to dry out naturally.

If you want to use weights instead of a steam iron, then put some heavy books onto your warped floorboards about 5 – 6 times, depending on how bad they are, until they’re flat again. This should take around three days if done regularly enough.


You should always store your wood indoors to avoid the harsh chemicals that are found in rainwater; these can cause your furniture to warp.

When you store it for three months, then turn the wood every two weeks so that it dries out evenly.

If you’re looking for a quick fix on how to repair pallets or floorboards, then this method should come in very handy. However, however, if they’ve warped enough where they aren’t only bowed but also curled too, then this isn’t always advisable as there’s a chance that what you do may make them worse. The reason being is because steaming them back into shape without using plywood underneath could cause even more damage and stress cracks that will run across your boards, thus destroying them.

The Iron Method

The steam iron method is best done with old or new floorboards as they’re less likely to split when you apply the force onto them. However, however, whether you use older boards or ones that are newer, then make sure they’re no more than 5mm thick; otherwise, this could cause problems later on. Boards that are thinner than this usually warp very easily and can snap like twigs if not careful enough.

First of all, measure the length and width of your warped board(s) so that you know exactly how much plywood you will need. Make sure it is slightly bigger than what you actually require, as this will allow for some shrinkage during the process itself. Once cut to size, place your pieces together using an adhesive. Ideally, you should use PVA glue as this is mainly water-based and won’t damage the wood.

Now that your boards are clamped together, let the adhesive dry for around 12 hours before sanding them to give them a smooth finish and remove any excess glue.

The Sunlight Method

The sunlight method is probably the best for repairing old warped floorboards, primarily because it’s very easy to do and has an excellent chance of working. It does, however, require some patience as this process can take several days, especially if you’re dealing with severely warped wood.

First of all, collect some heavy books, then place them onto your board(s) about 5 – 6 times until the warp has gone out of them. Ideally, you should leave them overnight, but if time is a problem, then this can be done in one day by placing a heavy book on top every hour or so.

Now that your warped floorboards have been flattened, it’s time to flatten any remaining high points that have been missed. To do this, simply dampen your boards slightly so that they aren’t too wet and place them flat on top of some heavy books to flatten them up again.

After you’ve finished fixing the warp in your floorboards, it’s time to sand down any rough edges or any parts where there are still high points.

The Heat Method

This is one of the easiest ways to fix warped floorboards, but it does require practice before you do an actual board, as this can cause potential problems for your floor.

First of all, clamp your boards together using your plywood on top of them. Also, make sure that they are roughly equal in size; otherwise, there’s a chance that some of the boards could warp and remain untouched by this method.

Now that your warped floorboards are clamped together, you need to heat them up with an ordinary hairdryer. This process should be done until the wood changes color slightly, although there is a chance that it may become very hot or even burn, so use this technique carefully.

Once your warped floorboards have been heated up, you will notice that they are flat once again, although there is a chance that some of the boards may be slightly warped. If this is the case, then simply repeat the process to them until they’re all one straight line.

The Oven Method

This method requires some advanced preparation and should only be used as a last resort to fix your warped wood. Although it’s more reliable than using heat guns or hair dryers, this process can take several hours to complete, so make sure you’ve got enough time on your hands before beginning.

First, remove any glue from your boards; otherwise, it could melt onto the oven trays, which makes cleaning harder later on.

The Pressure Method

This is probably the least reliable way to fix warped wood, but if done correctly, it can be a fairly effective method. Although this process requires a lot of patience and a little bit of skill, you will see that your warped boards are once again flat.

First of all, clamp your boards together using one sheet of plywood on top, then place them face down onto some sturdy books until they’re completely flattened.

Now that you’ve flattened your warped floorboards, place them face-down onto a hard surface such as concrete or paving slabs so that the warp is being pushed back into the floorboard itself. You should use some heavyweights for this part; otherwise, it won’t have much effect on the warping process itself.

The Nylon Paper Method

This method is probably the simplest and has a very high success rate, so if you choose to use this technique, then be prepared for great results.

The Nylon Paper Method: Use nylon paper to tightly wrap any warped boards and leave it in place for 48 hours before removing the tape and unwrapping the floorboards. This method will help flatten out your warped wood quickly and easily without damaging them too much.
