Hello, can large unevennesses caused by cracking and peeling part of the leveling trowel under the PVC FAtra floor can be repaired with a larger layer of glue? The floor designer suggests this method, but I, as a layman, am worried that it will not eliminate the problem. He poured the part of the peeled off again with a spatula, sanded it by hand and glued it with PVC. After a few days, the inequalities began to emerge, sinking into the holes. Thank you for your feedback.
