Tips and guidelines for repairs


Peaking describes a situation in which the laminate planks push against each other and lead to elevations at the joints. There are a number of reasons why this can happen. The most common cause of spikes is a lack of expansion space between the laminate floor and the walls around the installation or a lack of expansion space between the laminate floor and the laminate moldings.

This situation can be easily remedied. Simply follow the perpendicular of the top board to the wall or ledge, remove the required ledge - if it abuts the wall, remove the baseboard and cut out a section or enough of the laminate board that meets the wall or ledge to accommodate it the floor has more room to expand. (Diagram 1 & 2)

However, the peaking will not go away immediately, it may be necessary to place a weighted object on the peaking areas for a period of time.

Another reason for spikes could be because the battens have been fastened/nailed to the floor in the doorways or around the room, preventing the floor from expanding. Remember that a laminate floor is a floating floor and must not be attached to the subfloor or moldings at any point as this will not allow the floor to expand and contract like these floors do.

Peaking can also result from a continuous floor surface without a central "T" being too long in one direction? Shape compensator for pressure relief. This generally happens in areas where the ground runs over 27 feet in each direction - this number varies by manufacturer.

buckling or warping

Wrinkling or warping is almost always the result of moisture and/or water damage.


Laminate floors are attacked by water in many ways. High levels of moisture in the air can sometimes cause buckling or warping. Excessive water on the surface of the floor can also cause buckling or warping. For this reason, it is important never to wipe a laminate floor wet.

The most common cause of edge warping or denting is water or moisture rising from the subfloor combined with a lack of a moisture barrier.

Creases or warping can also be the result of poor product construction. Laminate floors are laminated under extremely high pressure. For this reason, a leveling layer is required on the underside of the planks. This layer is made of a rigid material that balances the pressure exerted from above.


Gaps are not common in laminate floors. Gapping is a situation where the laminate planks tend to separate, resulting in gaps between the planks.

This situation occurs when the temperature drops well below the point considered normal (60°-80°). For this reason, it is very important that you acclimate your flooring to the room temperature and conditions of the room in which the laminate is to be installed prior to installation.

mold and mildew

Both residential and commercial property owners and the general public are increasingly focusing on mold and mildew issues. In virtually every situation where there is a mold problem, there is an excess moisture problem. To prevent, control, or eradicate mold and mildew, one must first identify, assess, and eliminate the source of excessive moisture.

If prior to removing an existing flooring or installing new flooring or repairing an existing laminate floor, there are visible signs of mold or mildew or the presence of a strong musty odor in the area where the flooring is to be removed or installed The problem should be identified and corrected.

Expanding High Density Fiber Board (HDF)

The core (middle part) of a laminate floorboard consists of HDF. However, most laminate cores are treated with water-repellent chemicals. If your flooring is water damaged, your only remedy is to replace the affected planks.

Broken corners

Excessive chipping at corners can be caused by:

a) Incorrect installation methods used. Be careful when using a tapping block and hammer to install floating floors. Often, poor installation can result in marks, indentations, and chipping.
b) Cleaning the floor with a vacuum cleaner rasp bar attachment.
c) Poor handling

"Off Register" a manufacturing defect

"Off Register" is a situation where the floor pattern on a floor board does not match the pattern on the connecting board. The manufacturers allow a deviation. However, this situation almost never occurs, and if it does, simply replace it with additional existing material.


Although very durable, it is normal to find minor scratches as a result of daily wear and tear. Bellawood'sAbkrateoffers a great solution to improve the appearance of some scratches.

Fortunately, this situation is easily remedied with the help of a floor repair kit available at your local home center. These kits may include acrylic or latex putty, wax pencils or crayons and are color coded to match the floor. Take a plank of flooring with you for color matching.

In the event of major damage, it may be necessary to replace the damaged circuit boards. The introduction of glueless laminate flooring has resulted in a floor that is both easy to install and repair.

You need additional laminate flooring for this.

To replace boards that are near walls or trim, do the following:

1. Begin by removing the baseboard or molding. Be careful not to damage the molding.
2. Remove the boards starting with the ledge until the damaged board is accessible.
3. Replace the damaged board and then the remaining boards you removed by snapping them back into place.
4. Replace the molding.

Repairing a laminate plank closer to the center of the room is more detailed and time-consuming.

The procedure involves removing the damaged panel using a saw or router and then replacing the panel using a sufficiently waterproof adhesive.

Contact a professional installer or follow these steps.

1) Mark the damaged board 1-1/2″? from ends and side. Drill 3/16″? Holes at the corners of the marked area.
2) Cut along the lines between the drilled holes and remove the middle section. Then cut the remaining piece in the middle on both sides and remove.
3) Prepare a replacement board by cutting and removing the factory tab along the long and short ends of the board. The figure below shows the two common types of locking systems available.
4) Apply a resin adhesive (PVA) to the cut edges and replace the panel by aligning the groove on the replacement panel with the key on the adjacent panel and snapping it back into place.
5) Make sure all edges on both sides of the joints are level. Use a heavy object to apply pressure for at least 24 hours. Make sure the weight is evenly distributed over the new piece.

Prevention is better than cure. Place floor mats at doorways to reduce the amount of sand entering the home. It's a good idea to place felt pads under the furniture legs as this will prevent scratches caused by the furniture being dragged across the floor. Also keep the nails of large pets neat.
