Then, what causes plasterboard to crack?
Fluctuations in temperature and humidity levels can cause framing members and drywall to expand and contract, resulting in cracking. Like other wall cracks, these can be re-taped and painted.
Similarly, is it normal for plaster walls to crack? Vertical and horizontal cracks in drywall or plaster walls typically indicate drying and shrinkage, which is normal after construction. Jagged cracks, stair-step cracks and 45-degree angle cracks generally signify structural movement or settling issues that are occasionally serious but usually harmless.
Also asked, how do you fix cracks in plasterboard?
- Spread the Joint Compound. Stir up the joint compound, then put a small portion on the edge of the six-inch taping knife.
- Apply Tape to the Crack. With the 6-inch knife, press the paper tape into the wet area, directly over the crack.
- Apply Joint Compound Over the Tape.
- Finish the Repair.
Do cracks in walls indicate a structural problem?
Most small cracks in drywall or plaster walls are not serious and are caused by seasonal expansion and contraction of the wood framing in your house over time. Larger cracks in your walls, however, can indicate structural or foundation problems.
