How To Fill Cracks In Wood Floor
Introduction
How To Fill Cracks In Wood Floor: Wooden floors add warmth and elegance to any home, but over time, cracks may appear due to various factors such as changes in humidity, aging, or improper maintenance. These cracks not only detract from the visual appeal of the floor but can also pose a tripping hazard if left unaddressed. Fortunately, filling cracks in a wood floor is a manageable task that can be undertaken by homeowners.
Before delving into the process of filling cracks, it is essential to understand the wood floor causes behind their formation. Wood is a natural material that expands and contracts in response to changes in temperature and humidity. These fluctuations can lead to the development of small to large cracks over time. Additionally, improper installation techniques or lack of maintenance can contribute to the occurrence of cracks.
To begin filling cracks, the first step is to prepare the floor. Thoroughly clean the cracks and the surrounding area, removing any dirt, debris, or loose particles. A vacuum or broom can be used for this purpose. It is crucial to have a clean and dry surface to ensure proper adhesion of the filler.
Next, select the appropriate wood filler based on the size and depth of the cracks. For small cracks, ready-to-use wood fillers are commonly used, while larger or deeper cracks may require an epoxy resin filler for a stronger and more durable repair.
What do you use to fill cracks in wood floor?
You can fix minor splits and fractures with epoxy (wood glue) and filler. First, fill the crack with epoxy, then apply the filler to help conceal it. Allow both to dry and harden completely before sanding and finishing the area.
When it comes to filling cracks in a wood floor, there are several materials commonly used to achieve a smooth and durable repair. The choice of filler depends on the size and depth of the cracks, as well as the desired level of strength and longevity. Here are some of the materials that can be used:
Wood Filler
Filling tiny to medium cracks in a wood floor with wood filler is a common practise. It’s a putty-like material that comes in different shades to complement various types of wood. Wood filler normally consists of wood fibres bound together with an adhesive like epoxy or vinyl. It can be applied with a putty knife or scraper to the cracks with little effort. It can then be sanded and stained to match the rest of the floor once it has dried.
Epoxy Resin Filler
For larger or deeper cracks, epoxy resin fillers are often preferred due to their strength and durability. Epoxy is a two-part compound that consists of a resin and a hardener. When mixed together, it creates a strong adhesive that can bond well with wood surfaces. Epoxy resin fillers penetrate deep into the cracks, providing a robust and long-lasting repair. They can be applied using a putty knife or syringe and require sufficient curing time to harden properly.
Sawdust and Glue Mixture
Another DIY option for filling cracks is to create a mixture of sawdust and wood glue. Collect sawdust from the same type of wood as your flooring and mix it with wood glue to form a paste-like consistency. Apply the mixture to the cracks, ensuring it fills the gaps completely. After drying, sand the surface to achieve a smooth finish. This method is cost-effective and can produce satisfactory results for small cracks.
Latex Caulk
Latex caulk is a flexible sealant commonly used for filling gaps and cracks in various materials, including wood floors. It is available in different colors and can be applied using a caulk gun. Latex caulk is ideal for minor cracks and gaps that may occur due to seasonal changes or normal wood movement. It provides a flexible seal that allows for slight expansion and contraction of the wood.
Should you fill the cracks in hardwood floors?
In our professional opinion, if your old wood floor has gaps, just live with them. They will look worse if you fill them and the wood filler cracks. Try to bring up the humidity in your home or wait for summer to come around to see them close up a bit.
Filling cracks in hardwood floors is generally recommended, especially when the cracks are noticeable or pose a potential tripping hazard. Here are some reasons why filling cracks in hardwood floors is beneficial:
Aesthetics
Cracks in hardwood floors can be unsightly and detract from the overall appearance of a room. Filling the cracks helps to restore the smooth and seamless look of the floor, enhancing the visual appeal of the space.

While filling cracks in hardwood floors is generally recommended, it is important to consider the severity and extent of the cracks. For minor hairline cracks, filling may not be necessary, as they are often a result of natural wood movement and do not affect the floor’s integrity. However, for larger or deeper cracks, filling is advisable to prevent further damage and maintain the floor’s appearance and functionality.
Why is my wood floor cracking?
If you have cracks in your hardwood floor, the problem is likely to be low humidity and low moisture in the room, causing the wood to dry out. This could happen for a number of reasons, including: open fires, log burners, underfloor heating system running too hot, and also the frequent use of air conditioning units.
Wood floor cracking can occur due to various factors, and understanding the possible causes can help identify the appropriate solution and prevent future damage. Here are some common reasons why wood floors may develop cracks:
Natural Wood Movement
Wood is a natural material that expands and contracts in response to changes in humidity and temperature. Fluctuations in moisture levels can cause the wood to swell or shrink, leading to the development of cracks over time. This is particularly common in environments with significant humidity variations.
Insufficient Acclimation
Improper acclimation of wood flooring before installation can contribute to cracking. When wood is not given enough time to adjust to the moisture levels of its surroundings, it may expand or contract after installation, leading to cracks.
Poor Installation
Inadequate installation techniques can put stress on the wood floor, leading to cracks. This can include improper nailing, insufficient adhesive application, or failing to leave appropriate expansion gaps around the perimeter of the floor.
Moisture Imbalances
Excessive moisture or dryness can cause wood floors to crack. High humidity levels can lead to wood swelling, while low humidity levels can cause the wood to shrink. Poor moisture control within the home or exposure to water leaks can contribute to these imbalances.
Aging and Wear
Over time, wood floors naturally undergo wear and tear. As they age, they become more susceptible to developing cracks. This can be exacerbated by heavy foot traffic, furniture movement, or impacts.
Are cracks in floor normal?
It’s common for cracks to form in a home’s foundation after it’s built. Most times, the cracks are normal, non-structural settlement cracks. However, there are many reasons a foundation cracks, such as the home’s settling, concrete shrinkage and curing, stress, and poor construction.
Cracks in floors can be relatively common and are often a result of various factors. While some cracks may be considered normal and harmless, others may indicate underlying issues that require attention. Here’s a closer look at the different types of floor cracks and their normality:
Hairline Cracks
Hairline cracks are thin, shallow cracks that are often considered normal and not a cause for concern. These cracks are typically a result of natural wood or concrete movement due to changes in temperature and humidity. Hairline cracks are common in both wood and concrete floors and are generally cosmetic in nature. They do not usually affect the structural integrity or functionality of the floor.
Settlement Cracks
Settlement cracks occur in concrete floors and are a result of the settling or shifting of the building’s foundation. These cracks are more common in new constructions or in areas with unstable soil conditions. While settlement cracks can be concerning, especially if they are wide or jagged, small hairline settlement cracks are relatively normal and can be expected to some extent.
Structural Cracks
Structural cracks are larger, wider, or deeper cracks that can indicate significant underlying issues with the floor or building structure. These cracks may be a result of structural movement, foundation problems, or excessive loads on the floor. Structural cracks should be evaluated by a professional as they may require immediate attention and repairs to ensure the safety and stability of the structure.
Expansion and Contraction Cracks
Floors made of materials like concrete, tile, or vinyl can experience expansion and contraction due to temperature and humidity changes. These fluctuations can lead to small, temporary cracks. Expansion joints or proper installation techniques can help minimize the occurrence of these cracks.
Cracks in Wood Floors
Wood floors can develop cracks due to natural wood movement, aging, or insufficient installation and maintenance practices. Small cracks in wood floors are generally considered normal and can be addressed with regular maintenance, such as filling and refinishing. However, larger or recurrent cracks may indicate deeper issues and should be assessed by a professional.
