The solid wood floor is deeply loved by consumers because of its soft and comfortable foot feeling, simple and beautiful color, healthy and environmentally friendly. However, the installation of luxurious solid wood flooring soon appeared as a tile-like deformation, which cannot be annoying. In November 2007, Ms. Zhao, a consumer in Jinan, Shandong, purchased a brand of solid wood flooring of 509 square meters in a floor store in Jinan, which was used for the floor covering of the villa and was completed on December 9. In April 2008, the family had not yet checked in. Ms. Zhao found that there was a tile-like deformation in the local area of ​​the floor. Because the floor was paved in two batches, the visual effects were different. The first batch was very flat, while the second batch was uneven. The appearance of tiles and the color is relatively shallow, so Ms. Zhao suspects that there are differences in the quality of the two batches of products.
After the dealer learned the situation, he rushed to Ms. Zhao’s home to check the scene and found that the floor did appear to be partially tile-like. Among them, the partial floor on the first floor has a slight tile shape, and the east and middle halls on the second floor have obvious tile shape, and the floor in other places is intact. In addition, on the first floor, the chandeliers in the east and middle halls of the first floor were found to have peeling water and wall paint. On the second floor, the lower walls of the north hall and the north window of the east hall were marked with rain. At the same time, they also measured the moisture content of the floor of the floor, and found that the moisture content of the first floor was 11% to 15%. The floor space of the east and middle halls on the second floor was about 18%, and the third floor was finished. The floor moisture content of the benefits is only 10% to 13%.
According to on-site observation, measurement and visual analysis, the manufacturer believes that the tile-like phenomenon on the above floor is caused by the moisture expansion of the floor caused by the moisture of the floor and the wall.
In order to properly solve this problem, on July 18, three experts including the vice president of the China Timber Distribution Association Floor Circulation Committee and the associate professor of Beijing Forestry University, Yang Meixin, made a special trip to Jinan to coordinate the matter.
After careful observation and testing, Ms. Yang Meixin, a well-known expert in the flooring industry, explained to the user the reasons for the tile-like phenomenon of solid wood flooring. She said that after the paving of the wooden floor, there will be some occasional tile-like deformation. This situation is mainly related to the conditions and environment of installation. The specific reasons are as follows: 1. The ground water content is higher before paving; 2. The pavement is not occupied for a long time, and there is no timely ventilation; 3. The ground or wall is partially leaked; 4. When cleaning the floor, it is not used for wringing. Mop the mop to the floor.
She reminded that before paving the floor, it is necessary to test the moisture content of the ground, and the paving can be carried out after reaching the standard. This is an important prerequisite for ensuring the quality of the project. The wall and floor slabs of the newly delivered residential buildings have a moisture content of 22% or more. When the dry wood flooring (water content ≤ 13%) absorbs moisture and expands, the slab becomes tile-shaped. In the process of interior decoration, if the cement mortar is stirred in the room, a large amount of water will penetrate into the floor. When the wooden floor is laid, a large amount of moisture in the potential floor will be absorbed by the back of the dry wooden floor, so that the back of the board is first The expansion causes the plate to deform.
The solution to the problem of tile deformation on the floor is: When a small amount of deformation is found after one week of initial installation, the problem is not serious. 3 to 4 rows of floors are removed on both sides of the room, and forced ventilation is performed by the fan, so that the floor is ventilated and dry. If the water in the floor causes the floor to enter the water, remove it as soon as possible, let the back of the floor face up and dry it, and restore it. Wait until the floor and floor are completely dry before re-paving. The only serious problem is to dismantle the floor, re-plate or re-lay after processing.
