This means that the material you use must be from an approved system that meets the requirements for water and vapour density in the Swedish National Board of Housing and Urban Development's Building Regulations (BBR) and in the Swedish Building Ceramics Council's Industry Rules for Wet Rooms, applicable to BBV 21:1.

NOTE! Our waterproofing systems should not be used outdoors or in uninsulated cellars where there is a risk of additional moisture.

Attach with tile adhesive

Tile adhesive is the material used to attach tiles in your wet room. You must use tile adhesive when affixing tiles, mosaics, and stone veneer to walls and floors. Tile adhesive is usually made from cement and comes in powder form.

When renovating your wet room, it is important that you use tile adhesive specifically designed for wet rooms.

Our tile adhesive is included in our waterproofing systems for wet rooms, and can be used on concrete, self-levelling floor screed, brick, plaster and plasterboard, both indoors and outdoors. Have you opted for underfloor heating in your wet room? No problem! Biltema’s tile adhesive is perfectly suitable for both electric and waterborne underfloor heating.

When applying the tile adhesive, make sure to spread it equally over the substrate. Then drag a notched trowel across the adhesive. Use the correct trowel size according to the thickness and size of your tiles.
