The solid wood floor became tiled after 7 days of installation, and each piece is, what is the reaso

Hardwood floors are sawn into veneer. Perpendicular to the growth rings is the "radial cut lumber", and parallel (approximate) to the growth rings is the "chord cut timber". The chord cut timber is generally new timber and sapwood, which is close to the bark.

So, let's look at the end of a piece of floor, the pattern is parabolic; Looking at the surface of the floor, it is a "pattern" and also called "mountain grain" (the diameter cut material is a straight grain).

You imagine a flat pole. When things are heavy, they start to bow and when they are light, they are straight.

Your floor is too, wet, the age line at the end becomes straight, dry, and the growth ring line at the end is bent.

This is the deformation of the physical properties of wood shrinkage and wetting.

To understand what the reason is, you need to do the following:

1. Remove the floor and check the ground humidity. Usually it should be within 15%. In geothermal environment, not less than 8%. 6% is very dry and you'll feel like you're sitting on the stove. 5% is impossible, that is to dry to the degree of carbonization by external force.

2. Check the floor humidity (moisture content). Usually 10%-13% in the north; 12%-17% in the South. In the south, about 17%, the relative humidity of the air is 100%, and the walls are covered with water beads.

3. Check whether the moisture-proof film is in good condition. The moisture-proof film needs to be lapped for 10CM and sealed with transparent tape. It needs to be rolled up 8cm around the perimeter and covered with a press strip and baseboard.

4. If there are keels and blockboards, please adhere to the moisture content of these accessories.

Find the cause and know how to solve the problem.

Wait for you to explain why.
