Compound is not hardening or taking too long.

Check the product's expiry date. Ensure the environment is not excessively cold or humid. Verify that the correct mixing ratios were used.

Cracking or shrinkage after application.

Apply in thinner coats, especially over larger areas. Ensure proper joint preparation and that the substrate is stable. Avoid applying in extreme temperature or humidity conditions.
