Drywall allows you to speed up and reduce the cost of finishing, but this material is quite fragile. Cardboard gives the sheets additional strength, so cracks appear mainly in the seams.

Causes of cracks
• Expansion and contraction when sheets get wet and dry. The humidity in the room is constantly changing, gypsum absorbs and gives off water during these fluctuations. The process proceeds unevenly, so there are multidirectional loads.
• Different thermal expansion of the drywall itself and the frame.
• Uneven precipitation of the building
• Warping of the wooden frame during drying.
To reduce cracking, you can either reduce the loads in the joints of the sheets, or make the seams stronger.

Ways to reduce stresses in the seams of GCL
• Compliance with the humidity regime. Before installation, it is necessary to finish all work related to the release of moisture. Screed, plaster, mortar in the joints of brickwork, concrete in additional bases – everything should dry.
• Compliance with the temperature regime. Manufacturers forbid to putty seams at temperatures below 10 °, but it is better to do it in conditions close to operational (20 -25 degrees). Drafts during the execution of putty and its drying should be excluded.
• Careful sealing of all cracks in the exterior walls to avoid condensation.
• Exposure of the mounted GCL before sealing the seams. The sheets should hang off for 2-3 days. During this time, excess moisture will evaporate from the gypsum, and the stresses in the frame will decrease.
• The gap between the drywall on the walls and the floor. This will prevent possible getting wet when washing.
• Absence of rigid connection of metal frame racks with guide profiles. Rack profiles are simply inserted into the guides, and are attached to the walls through suspensions.
• The gap between the metal frame posts and the ceiling. This prevents the consequences of precipitation of the structure.
• Correct layout of the sheets. Cruciform seams and drywall joints on racks forming openings in the walls should be avoided.
• The use of dry material in the manufacture of wooden frames.

Methods of strengthening seams
• Use of high-quality putty
• Connection of sheets on frame elements
• Reinforcement of seams with paper tape. Serpyanka is worse because the mesh does not work well for the shift.
• Compliance with technology. It is necessary to make a chamfer on the edges that occur when cutting sheets, priming such seams. Putty the joints in two times. The previous layer should be dried.

Compliance with simple rules will avoid cracks. Drywall will last a long time. Homemade porn https://www.amateurest.com/ USA.
