We’ll cover all of this in our article.

Main causes of damage

Any an action committed in case of non-observance of the installation technology, or mistakes made in the process of cleaning the surface of the floor with a laminated coating, will certainly have negative consequences. The most pressing issue is what to do if the laminate is swollen from the water. Particularly sensitive to various influences behave budget options laminate flooring. There are several reasons for the formation of bumps on this type of surface:

  • poor quality of the components used;
  • violation of the operating rules;

Such samples are subject to absolutely all types of impact, and you cannot do without problems during their operation.

Material quality

Budget types of laminate are made from pressed paper with a low content of sealing resins and the thinnest PVC coating. The decorative layer has very thin edges that can be deformed at the slightest stress during installation, thereby exposing joints or forming local surface swellings. Moisture under the protective surface of such a coating leads to swelling of the base of the laminate. If the laminate swollen from the water, how to fix the formation of volumetric tubercles? You can find out by looking at some recommendations.

Terms of use

gher quality models of laminated flooring have a high cost , they perfectly join and poorly pass moisture at the joints. However, violation of the operating rules (especially with regard to wet cleaning methods) can lead to the penetration of moisture under the top layer of material. And the MDF base contains wood fibers that are subject to deformation upon contact with water. Avoid contact of high temperature sources with the surface of the laminate. Particularly sharp heating can also lead to bloating.

Basic errors

If the laminate is swollen from water, how can I fix the defect? Damage can take as separate segments that make up the coating, and whole areas, including many components. Poor quality material becomes especially unusable when used in the kitchen or in the bathroom due to the combined effect of various factors. Particularly dangerous is the swelling of the laminate after water, which makes it unsuitable for further operation. Also, the floor may become unusable due to untimely elimination of the causes of damage. Spilled liquids that were not wiped off in time are especially dangerous for such a surface.

Process violations

In addition, there are strict rules for the installation of these structures. Laying planes should not be in contact with the wall, but should have a technological deviation of 5 millimeters around the perimeter. After all, the laminate is able to expand with increasing room temperature, which will lead to its swelling in case of contact with the wall. The gaps between the lamellas will always be limited.

Methods of repairing the coating

Often, when moisture gets into contact, only one of the coating elements becomes unusable. If the laminate is swollen at the joints from the water, in this case, the stock prepared when purchasing the material can be very useful. If there is no such stock, then you can pick up a replacement only by comparison, taking a coating sample with you to the store. The most difficult thing is to replace the area in focus. In this case, the color should fully correspond to the damaged sample.

Worth remembering that the necessary clearance should not be less than 5 millimeters. If after removing all obstacles the surface does not begin to level out, it is necessary to perform an autopsy in the areas of swelling. After removing one of the components of the coating, it is worth inspecting the substrate for moisture accumulation. In some cases, it is advisable to replace the substrate in order to understand how to restore a laminate swollen from water.

Using an Iron

At the site of the formation of the bulge, a metal ruler is applied to the junction of one of the lamellas, which is ironed with a metal iron. After the moisture that has got on the base of the laminate evaporates through the joints, the coating plane will begin to level out. This will remove the bloating.

Difficulties in replacing

If the laminate has swollen after water, what should I do? Replacing single coating lamellas is fraught with certain difficulties. When disassembling a plane, there is a chance of chips on adjacent elements. In this regard, all actions should be performed with extreme caution. If the tongue-and-groove parts were connected not in the lock, but with the help of special glue, then the damaged fragment can be removed only in its entirety. To do this, using the marker on the diagonal of the lamella, a line is drawn along which a cut is made using a grinder, and the cut strip is removed in parts.

It is necessary to cut the marked component with indentation so as not to damage adjacent elements. To solve such problems, there are several different tools, equipped with additional devices.
