Laminate is a popular floor covering that is often used in residential and commercial spaces. However, it is not immune to moisture, and one of the most common problems faced by laminate flooring owners is water swelling. Swelling of the laminate can cause damage to the appearance of the floor and reduce its service life. In our article, we will consider what to do if the laminate is swollen from water, offer effective solutions and preventive measures that will help avoid this problem and keep your laminate floor in perfect condition.
One of the most obvious reasons for the swelling of the laminate coating is the penetration of moisture under the laminate slats. Laminate consists of wood particles that are lubricated with a special material, and if water gets between these layers, it can cause them to swell. This is especially true in areas with high humidity, such as bathrooms, kitchens or rooms with significant humidity levels.
In addition, damage to the upper protective layer of the coating, which may occur as a result of careless handling of the floor, impacts or scratches, can contribute to the swelling of the laminate. These damages create favorable conditions for the penetration of moisture, which then causes swelling of the material.
Why laminate reacts to moisture
Laminate is a floor covering, the structure of which plays an important role in its interaction with moisture. Let’s consider some features of the structure of the laminate, which determine its reaction to moisture, and also consider the effect of moisture on the material.
Features of the laminate structure:
- Top protective layer: Laminate has a strong top protective layer that makes it resistant to wear, scratches and UV rays. This layer is made of high-quality synthetic materials, which allows the laminate to maintain its attractiveness for a long time.
- Decorative layer: Under the upper protective layer is a decorative layer that reproduces the appearance of wood, tiles or other natural material. This layer adds aesthetic appeal to the laminate and makes it suitable for various interior styles.
- HDF (High-Density Fiberboard): The basis of laminate is high-density boards (HDF), made of wood fibers reinforced with resins. This base gives the laminate stability and high strength.
Effect of moisture on the material:
- Moisture absorption: Laminate is able to absorb moisture through small cracks and damage in its structure. This can happen during floor cleaning, heavy rains at night or excessive humidity in the room.
- Swelling: Under the influence of moisture, the wood fibers in the laminate can swell, which leads to a change in the shape of the slats and the appearance of bubbles on the surface of the coating.
- Deformation: With long-term contact with moisture, the laminate can deform, bend or loosen, especially if there is no free space for expansion.
Understanding the structure of laminate and its response to moisture will help us in the following sections to consider effective measures to prevent swelling and damage to laminate flooring.
Prevention of laminate swelling
- Choosing the right type of laminate for the room:
The right choice of the type of laminate is determined not only by its aesthetic characteristics, but also by its properties of resistance to moisture. If you plan to lay laminate in a room with a high level of humidity, for example, in a bathroom or kitchen, choose a laminate with increased resistance to moisture or waterproof options. Such a laminate has a special protective layer or treatment that prevents moisture from penetrating into its structure.
Before buying laminate, carefully read the manufacturer’s information on moisture resistance and suitable use in various conditions.
- Application of waterproof means:
If you have already installed laminate, or are going to do it, and the room has a high level of humidity, you should consider using special waterproof products for laminate. These products can be in the form of varnishes, sealants or waxes, which are applied to the surface of the floor. They help to form a protective barrier that prevents the penetration of moisture into the pores of the laminate.
Before using any products, make sure they are suitable for your type of laminate and follow the manufacturer’s instructions.
Remember that even with high resistance to moisture, laminate is not intended for wetting or long-term contact with water. Lacquered laminate surfaces can be resistant to some spills, however, it is important to wipe up moisture immediately and avoid standing water on the floor. Using the right types of laminate flooring and waterproofing products can help keep your floor from swelling and other moisture-related damage.
What to do if the laminate is swollen
First steps after identifying the problem
If you notice that your laminate has swollen or blistered due to contact with moisture, it is important to act quickly to avoid further damage and the spread of the problem:
- Wipe the surface: Immediately wipe the moisture from the surface of the laminate, especially from the bubbles that have formed. Use a dry, soft cloth or napkin to absorb moisture from the floor.
- Remove the source of moisture: If you determine that the floor is wet from a spilled drink or other source of moisture, remove the source immediately. Avoid leaving water or other liquids on the laminate as this can cause further swelling.
- Stun the room: Provide adequate ventilation in the room where the laminate is located to speed up the drying process. Install fans or open windows for air exchange.
Dismantling the affected laminate slats
If, after inspection, you find that the swelling of the laminate is significant, and the blisters occupy a large area, it may be necessary to dismantle the affected slats to replace or restore the floor:
- Remove the affected slats: Using pliers or another tool, carefully remove the swollen laminate slats. Remember that the laminate is usually connected with a lock, so you need to separate the slats, starting from the end of the floor.
- Inspect the backing: After removing the affected slats, check the condition of the backing. If it is knocked over or damaged, it will also need to be replaced.
- Replace the slats: If the damaged slats cannot be repaired, they can be replaced with new ones. Find the right laminate slats, taking into account the color scheme and design.
- Seal the slats: When installing new slats, make sure they are hermetically sealed to each other and to surrounding slats to prevent moisture from entering.
- Apply waterproof protection: After installing the new slats, you can apply a waterproof agent or varnish to further protect the laminate from moisture.
It is important to remember that dismantling laminate can be a difficult process, and if you are not confident in your abilities, it is better to contact a professional for repair work.
Restoration of the floor covering
If the laminate flooring in your home has swollen or blistered due to contact with moisture, and you are unable to replace the damaged slats or want to restore the damaged area, using the following methods can help restore the flooring:
- Dry the surface: Provide adequate ventilation and dry the floor. Use fans or dryers to speed up the drying process.
- Apply weight: If the floor is swollen, dry it and place heavy objects, such as books or boxes of belongings, on the affected areas to distribute the pressure evenly and restore the flatness of the surface.
- Use an iron: Place a cooking iron on the surface, heated to a low temperature, and iron the affected strips through a cloth or rag. This process will help smooth the surface and remove bubbles.
- Apply a repair compound: There are special repair compounds for laminate that allow you to restore the affected areas. Follow the manufacturer’s instructions for using these mixtures.
Prevention of swelling of the laminate in the future
In order to avoid problems with laminate swelling in the future, the following measures should be taken:
- Keep moisture under control: Avoid spilling large amounts of water on the laminate. Clean up liquid immediately after spillage and avoid wetting the floor.
- Use a mat: You can install a special mat or waterproof film material under the laminate, which will help prevent moisture from penetrating the surface of the laminate.
- Use rugs: You can place rugs or carpet tracks under furniture and at entrances, which will help protect the laminate from wear and contact with moisture.
- Regular inspection: Regularly inspect the laminate, especially in areas with an increased risk of swelling (such as the bathroom). Early detection of damages will prevent their spread.
- Apply waterproofing agents: Consider applying waterproofing agents to the laminate to help create a protective barrier and prevent moisture from penetrating the material’s structure.
Remember that precautions and careful maintenance will help keep your laminate in great condition and ensure it has a long life.
Conclusions
Laminate flooring swelling from water is a serious problem faced by many flooring owners. The causes of swelling are related to the penetration of moisture into the structure of the material, which leads to the swelling of wood fibers and the formation of bubbles on the surface of the laminate.
