POTENTIAL REASONS OF THE PROBLEM

The sealant should be replaced due to physical deterioration.

SOLUTION

Dismantling the existing sealant (silicone)

Good cleaning of the surface from dust and loose particles

Protect the area around the application surface with a paper tape

Apply a anti-mould silicone SEAL POOL

The sealant is formed with our finger, while it is still fresh
