Wood flooring is favored by consumers because of its aesthetics, warmth and practicability. However, due to improper construction and temperature conditions, various problems will arise in the use of wood flooring. What are the causes of the problem? How to solve these problems? Xiaobian understands with you.
Problem 1: Swelling Arch
Surface phenomenon: the wooden floor surface is partially arched upwards, or some wooden floors are arched upwards.
1, continuous rainy weather, the relative humidity in the air is too high, no moisture removal measures, the moisture in the air is absorbed by the wooden floor and then absorb and swell;>
2, the wooden floor is hygroscopically swelled after flooding;
3, the house is long-term empty, uninhabited, poorly ventilated, and the water in the stucco layer is evaporated and nowhere to be absorbed by the wooden floor. Moisture absorption expansion;
4, the moisture content of the base concrete is too high, the moisture barrier is not sealed and hygroscopic expansion;
5, the wooden floor paving is not pressed between adjacent plates Requires the extension of the seam, the moisture is swelled and swelled by the humid air, and even the lacquer surface is cracked;
6. The wooden floor covering area is larger or wider, and no segmentation measures are taken.
Precautions: Always open the window to ventilate; and reserve structural extension joints, segmentation joints and adjust the extension joints between adjacent plates.
Solution: When the function is not affected, it can be used for a long time. After the moisture content of the wooden floor is balanced with the relative humidity in the air, the dismantling and resurfacing schemes are taken as appropriate; or all are removed. Open the resurfacing, adjust the section seam and the adjacent section to reserve the seam.
Problem 2: Floor cracking
Surface phenomenon: fine cracks appear on the painted surface of the wooden floor, and the paint film peels off in severe cases.
1, when the climate change is large, the moisture content of the wood floor is too large or too low, the wooden floor appears dry shrinkage or swelling, causing the paint film to crack; P>
2, the sun is exposed to the sun or the long-term wind blows, the wooden floor appears to shrink and shrink, and the paint film wrinkles and cracks;
3, the wooden floor is damp and the water content increases. Swelling, causing the paint film to crack.
Preventive measures: Select the wooden floor of a good quality manufacturer, and the adhesion, elasticity and wear resistance of the paint film can be guaranteed.
Solution: a small amount of paint film cracking, can be repaired by touch up. If the cracking area is large, it can be re-painted after being smoothed. If the single wooden floor paint film is cracked longer, the wooden floor can be replaced by a single piece.
Problem 3: There is sound on the wooden floor when walking
Performance phenomenon: After the wooden floor is paved, there is a creaking noise when walking, or a single squeaking cracking sound Wait.
1, the concrete base layer is not flat, the spacing between the mats is too large, the keel cushion is too high, etc., so that the walking parts of the frequently moving parts are loose, the keel elasticity increases. The up and down displacement occurs, resulting in a decrease in the firmness of the keel pavement;
2, the moisture content is too high when the keel is paved, the moisture content is reduced after the gradual drying, the nail holding force of the wood is simultaneously lowered, and the keel installation is loosened. ;
3. The moisture content of the concrete base layer is too high, and the moisture-proof insulation layer or the moisture-proof insulation layer is not completely sealed, so that the keel absorbs moisture, the water content increases, the distortion occurs, and the keel installation loosens; /P>
4, the keel material density is too low or the cross-sectional area is too small, the nail holding force is insufficient, the nail diameter is too small, the length is too short, the keel paving flatness does not meet the requirements, resulting in insufficient installation firmness; /P>
5, wood floor rafts and troughs due to climate change when the wooden floor is swollen and dry, the gutters are detached and do not work. When it is too tight, it rubs against each other when it is swollen;
6 Excessive dry weather, weakening the nailing force of the wooden floor and keel, loosening the connection between the wooden floor and the groove, excessive moisture makes the wooden land Lateral expansion, to produce a slight expansion extrusion bagging the loosening of the keel, that the same nail holding force is weakened;
7, the installation process is not standardized.
1, check the flatness of the concrete base layer before construction, and repair until the requirements are met before continuing construction;
2, before construction Check the moisture content of the concrete base layer or the integrity of the moisture barrier;
3. Check the cross-sectional size and water content of the keel;
4. The larger the contact area of the concrete base during keel paving The firmer the installation, the more the bolster part, the higher the bolster, and the more likely it is to loosen.
Solution: Construction conditions and concealed works should be strengthened to ensure the flatness of the concrete base layer and the moisture-proof insulation layer intact; if only excessive moisture or excessive dry weather occurs, observe when the climate is normal. If there is no obvious sound, you do not have to trim it.
Problem 4: Warping deformation
Surface phenomenon: the wooden floor is tilted upwards on both sides, like a tile.
1, the concrete basement moisture content or the adjacent wall moisture content is too high;
2, the concrete base layer has been splashed with water, mixed with water Materials, etc., causing the moisture content of the concrete base layer to increase;
3, failing to take waterproof and moisture-proof isolation and blocking measures as required;
4, the keel moisture content is too high, the evaporated water is The back of the wooden floor is hygroscopic;
5, the water pipe leaks under the surface of the wooden floor, the indoor temperature difference forms condensed water, etc.;
6, the surface of the wooden floor is wiped with a damp cloth.
Precautionary measures: The concrete base layer must be constructed after the moisture content is required. When the moisture content exceeds the standard, the moisture-proof insulation layer must be paved. The moisture-proof insulation layer should be sealed as a whole, and the waterproof and moisture-proof isolation and blocking measures should be taken.
Solution: Remove the wooden floor around the room to allow it to squirt, partially relieve the deformation, replace the wood floor with severe deformation; if the deformation of the wooden floor is large, the paved wooden floor can be removed Wait until the concrete base or keel is dry and re-paved. Re-paving the original usable wooden floor and replacing the wooden floor used.
QQuestion 5: Dry shrinkage
Surface phenomenon: After installation for a period of time, there is a phenomenon of separation between the wooden floor trenches.
1, the climate is continuous high temperature and dry and other abnormal weather environment, the wooden floor dehumidification is too fast, no humidification measures are taken;
2 The air is dry for a long time, the dehumidification is too large, and no humidification measures are taken;
3, sun exposure, long-term air blowing and other abnormal environmental factors, causing excessive dehumidification and shrinkage of the wooden floor;
4, the room is closed for a long time, no humid air is added, indoor air is dry;
5. When paving in wet weather, the paving interval between adjacent plates is too large, in case of dry weather, it appears Larger dry shrinkage.
Preventive measures: select the wood flooring material with good stability and moisture content to control the local equilibrium moisture content requirements; calculate and master the climatic conditions during the construction of the adjacent slabs of the wooden floor, appropriate Leave or not to stretch the seam; prevent sun exposure, it is not appropriate to close the doors and windows for a long time without ventilation, or partial concentrated blowing.
Solution: Wait for a period of time, after the moisture content of the wooden floor is balanced with the relative humidity in the air, replace the single block, or completely disassemble the resurfacing, and set the adjacent plate extension as required. /P>
