Frequently Asked Questions

Why is my polyurethane peeling off?

Polyurethane peeling off can be attributed to a couple of factors. Firstly, if the stain underneath the polyurethane was not adequately dry before applying the topcoat, it can cause improper adhesion, leading to peeling. It is crucial to ensure that the stain is fully dried before proceeding with the polyurethane application.

Secondly, the environmental conditions, specifically high humidity, can also be a contributing factor to peeling polyurethane. Excessive moisture in the air can interfere with the curing process and prevent proper bonding of the topcoat, resulting in peeling. It is advisable to apply polyurethane in conditions with low humidity to achieve a smooth and durable finish.
