Wet Room Tips

Tip no. 1

Follow the detailed instructions from the wet room membrane supplier (Lip, Ardex/Wedi, Alfix, Schönox/Sika, Mira, Knauf, Mapei and others).

Tip no. 2

Avoid using wet concrete primer on the metal surfaces of the square drain. 

Tip no. 3

Clean the drain’s metal surfaces before working with the wet room membrane

Tip no. 4

The membrane’s overlap on the drain’s metal surfaces must be at least 40 mm.

Tip no. 5

A liquid one-component wet room membrane must be applied in two layers, with a total layer thickness of at least 1 mm.

Tip no. 6

Be thorough with the wet room membrane – it is the waterproofing of the drain that makes the whole shower installation last for many years.
