The main mistakes in laying parquet.

                       Error in installing parquet caused many problems  

When installing parquet, there are often several unpleasant moments, such as cracks, landslides, warping, drying and others and mostly because of errors in installing
In this article we would like to give short answers to frequently asked questions.

In principle, all these questions and answers face the mistakes of placing a huge table. Due to its size, a solid table requires a lot of adhesives, fasteners, and uniformity of the base. The stress that occurs in large elements are infinitely higher, so the separation and expansion force is stronger.

A full description of the causes leading to the occurrence of certain deficiencies can be found in the articles on the placement of the parquet.
Errors in laying parquet have irreparable consequences.

Basic questions about floor installation:

1. Why does parquet crack?

Not only parquet can be weeping but also plywood. The crunch means that the structure is movable and the individual elements move when pressed. There can be several reasons: poor flooring, bad glue, poor quality parquet and plywood. There was a break from the base, see point 4.

2. On the floors are cracks or why the floor?

"Dried" wood, that is, has reduced its volume. The floors were wet during installation due to changes during manufacture and storage. The humidity in the room may be too low. The "contraction" of the parquet occurs when the humidity of the room is lower than the moisture of the panels. The evaporation of water from the wood causes a reduction of the parquet volume. If the process is acute, i.e., rapid, deformation or sagging may occur.

3. The edges of the cubes are rolled up, a box was formed, the edges of the floors are wavy.

Technologically, this is due only to the expansion of the top layer of the plate when the soil is drier. Then, due to the stress within the die, one turn is obtained, a similar feature is used in the thermostats, which connect two different metals in a single set. When heated, an element expands faster and the structure bends. Causes: a strong increase in humidity, the drying time has not developed tail before painting, the application of a large amount of paint in a day, the presence of unstable parquet in the film. We do not consider the water consumption because of the evidence.

4. Why did the soil fall off the ground?

If the soil is detached from the base, but has not been inflated and deformed, it is the reason for the glue, usually, quality parquet. The parquet has only glue, just press the nails for the first time. See what is on the bottom of the dice. When the tree is clean, the parquet is far from glue, glue - separation of plywood or rule, the rule - the destruction of the latter. Cheap adhesives when drying become limestone, remember! About the rule, read the articles about the placement of the soil, see above. Maybe the floor wastes glue or hurry to start the cycle, which did not allow the glue to adhere and block parquet. If a solid parquet or table "gets under your feet" or "rings", then this is just a consequence of a violation of the monolithic construction. And of course you cannot say anything about the moisture regime. An uncompacted mortar with a high water content, which works using moisture (plaster, sealing cement, etc.) without observing the rules that cause an increase in the moisture of the parquet and thus cause the wood to crack or deform. the last.

If the floor has been raised or removed from the concrete plywood, look also at the bottom of the plywood. A clean sheet: the glue did not hold, especially in the glue, in the recess of the rule, the remains of concrete, the destruction of the substrate. Do not rush to "drive" the quality of the materials. Maybe the technology is disturbed: the quality and strength of the rule, the drying time, still with primers.

5. The floor swelled or rose like a "little house".

the volume of wood increased with the increase in internal humidity, the plates rested against each other, there was no space to expand the parquet when it was swollen. Maybe the rule was wet, maybe there was a lot of glue, it did not fit the wood. There was no technological gap between the floor and the wall. For the same reasons, the plywood can be swollen. The parquet floor

If the ground was a wave after placement, then the reasons are the same. Due to the moisture change, the parquet began to expand, the internal tension appeared and as a result it increased in weak spots. It can manifest as single bulges and along the entire line of speech. Only for waves, you can take the deformation of the stumps, see point 3. It is possible to correct qualitatively only one partition with a possible truncation of the stumps or an analysis of the problem area to the next wall. All types of bites and injections are good in individual cases, if the damage is much better not to use it. The shooting of the rods are a "dead envelope" as it is.

6. The floor has fallen.

There are gaps under the floor. Perhaps the rule was not homogenous at first or collapsed during work and operation. This shows the quality of the rule. Read the articles about stacking.

7. When walking, the floor moves or "breathes".
 See point 4.

8. Under the floor is a void.

See point 4.

9. Dark spots appeared on the floor.

The moisture of the substrate is too high. From the interaction with water, the tree turns black, rots or forms fungi. These black and gray spots spread quickly through the wood. For example, a parquet floor laid the floor, the painters covered it with a film, and a month later they saw dark spots on the surface. The answer to the question of why dark stains appeared on the floor has also been completely transferred to the parquet and laminate floor. The protective lacquer layer acts like a film and prevents the escape of moisture. Look for the reason below. See the examples in the pictures for reference!

10. Draw the placement of the curve.

The relocation line has been eliminated. Low qualification of the teacher. He tried to condense the dice and changed them every time. As a result, at the end of the piece, the line "left". For example, the cubes in the tree must be offset by 90 degrees. If the parquet is of poor quality, the assistant attempts to make the end elements tighter, thereby reducing the angle, resulting in a curvature of the common line.

11. Matte, dark or whitish stains appeared under the varnish.

They did not let the glue dry. There is no room to go to the solvent and water, so there are dull spots under the paint. The grinding was carried out poorly, the remains of the chemistry (glue, lime and others) remained in the parquet and it came to a chemical reaction.

12. Broken or broken parquet.

This occurs when the moisture content of the wood changes, which changes the volume of the tree. If a sudden change, the parquet is exposed to a heavy load and due to the gap has no time to react with expansion or even drying. Causes: a strong increase in humidity, the drying time has not developed tail before painting, the application of a large amount of paint in a day, the presence of unstable parquet in the film. Bad flooring - too wet or too dry. We do not consider the water consumption because of the evidence. So, when the parquet is cracked, it is not difficult to understand the physics of the process, but there can be several reasons.
