How to Stop a Crack in Wood from Spreading?

Do you want to know how to stop a crack in wood from spreading? Here you will learn some of the procedures you can follow to prevent damages on wood from spreading.

There are several ways to keep cracks in wood from spreading, but for the sake of this post, we’ll focus on two fundamental procedures that are both simple and effective.

  1. The use of a wood filler or a wood epoxy
  2. The use of sawdust and glue.

The above procedures work for any type wood crack. However, there are some differences – wood filler works better in elongated, and narrow crevices, and sawdust and glue work well for widening gaps.

Why Does Wood Crack

Wood cracks happen due to changes in temperature and moisture level in the wood. When woods shrink as it dries, they begin to crack, causing the wood fibers to separate from each other.

How to Stop a Crack in Wood from Spreading?

There are two basic ways you can stop cracks in wood from spreading. You can use epoxy, wood filler or sawdust and glue.

However, it is essential to know that the nature of the cracks influences your decision. It’s worth knowing that epoxy is the best option if the break runs around the wood.

Epoxy will soak through the cracks, connect with the wood, and fill them because they are thin, whereas wood filler is best for medium-sized cracks.

Also, if you intend on sanding, staining, or painting your wood, wood filler is the way to go because it adheres well to the wood and doesn’t faze no matter how much sanding you do.

When opposed to epoxy, wood fillers take longer to dry. Sawdust and wood glue are good options when working with large cracks and saving money.

1.  How to Fix Cracks with Wood Filler or Epoxy?

You can use either wood filler or wood epoxy. Because the liquid epoxy fillers have a litheness, they are suitable for wood with deep cracks because they move quickly and deep into the wood. Wood fillers are simple to use, and the instructions below will walk you through applying wood filler or epoxy.

Step 1: Use Either Wood Filler or Epoxy

You can’t mix wood filler and wood epoxy; you can only use one of the two since the effects are different.

First and foremost, you must understand how each works and the uses before picking which of the two you prefer.

Wood epoxy, rather than wood fillers, works best with tight areas because it’s very light and thin, allowing it to penetrate impervious areas and thin cracks. Epoxy is the best choice for extended cracks because it forms a strong bond with the wood and fills the gap.

For surfaces with large fractures or missing short pieces of wood, wood fillers are the most acceptable option. One of the best things about wood fillers is that they’re inexpensive, and you can sand and paint them once they’ve cured. You must file and paint the wood so that it does not stand out from the rest of the wood.

Depending on the nature and extent of the crack, you can use either of the wood crack prevention methods, but both prevent cracks in the wood.

Step 2: Take Protective Measure

Working with these chemicals can be dangerous, which is why you must take precautions when working with them because they have chemicals.

Because wood epoxies are toxic and pungent, you’ll need to wear a standard respirator to protect your lungs from the fumes, especially if you’ll be working indoors.

If you’re working with epoxy filler or epoxy, it’s even better. Safety goggles are required since they will protect your eyes from chemicals splashing into your eyes and potentially damaging your lens. Wear long-sleeved clothing and gloves to avoid getting your fingers and torso sticky all over.

Step 3: Clean and Prepare Wood

You’ll need to clean your wood before applying your epoxy or wood filler. You probably think if that’s required. You must clean your wood by scrubbing it down with water and a light detergent, then rinsing it well with water and allowing it to dry completely.

After confirming that the wood is dry, the following step is to remove any waste.

Remove debris as that will clog the crevices that need filling. If not done, it is difficult for epoxy and wood filler to adhere to the wood.

Regardless of how little the debris is, clean it up. That will assist you in determining the crack’s size. If the fracture spreads to the opposite side, you may need to wrap the wood below with masking tape to prevent the epoxy or wood filler from pouring out.

Step 4: Take Action

Because epoxy comes in two forms, resin and hardener, you’ll need to mix it before applying it. You may add a little color to the epoxy to match the wood.

To activate your epoxy, mix it according to the manufacturer’s instructions, carefully mixing it to cover the crack. You don’t have to rearrange your wood filler if you don’t want to. All you have to do now is stir, and That’s all. Please apply to the crack and fill it in.

Step 5: Allow to Dry

Allow for at least a day of drying time after applying any of the two. Epoxy, on the other hand, dries faster than wood filler. After the paint has dried, add color to the wood using a permanent marker, sand, and paint it.

How to Stop Wood Cracks Using Sawdust and Glue?

The most acceptable and cost-effective approach to preventing broad and not too deep fractures is to use sawdust and glue. The procedures listed below will show you how to use this strategy.

Wood glue

Step1: Gather your sawdust and wood glue

First and foremost, gather your sawdust. To match the color of the wood, you may buy a bag or produce your sawdust out of waste wood or brand-new wood. Get standard wood glue as feasible.

Step two: Apply on Wood

You may use sawdust in conjunction with wood glue in two different ways. Fill the crack halfway with glue, cover the remaining portion with sawdust, apply glue, and cover with sawdust.

You may also use glue to fix the wood crack and cover it with sawdust; on ensuring that the sawdust bonds with the glue, apply slight pressure to it.

Step three: Leave to Dry

Allow for at least a day of drying after adding sawdust and wood glue. When you’re sure it’s thoroughly dried, sand the wood a little to smooth it out before staining it.

Tips & Tricks Using wood filler or Epoxy

You should also use wood filler if you plan on sanding, painting, or staining the completed product, as epoxy will not hold up to sanding and staining. On the other hand, wood fillers take longer to dry than epoxy.

If you’re going to utilize sawdust and glue, make sure to:

  1. Have a shallow and broad crack,
  2. You have a woodshop and enough sawdust on hand, or if you’re on a tight budget,
  3. It would be best to fill huge holes rather than minor cracks.

Stopping Crack On Wood Surface – Things to Consider

Below are some pro tips you need to consider and practice when it comes to stopping a crack in wood from spreading.

There are several essential things to remember while working with wood cracks or wood in general:

  • Before you start working on the wood, make sure it’s clean.
  • Allow plenty of time for the wood to dry after washing.
  • When working with wood cracks, ensure to remove all dirt.
  • Always operate in a well-ventilated location, and if you must work indoors, use a respirator, safety goggles, gloves, and long-sleeved clothes to protect yourself.
  • Make sure your epoxy resin is mixed and hardened entirely before using them.
  • Allow ample time for the wood to dry after using any of the treatments listed above.
