Bathroom waterproofing before tile
Small details around corners, drains and penetrations are where expensive failures often start.
Critical areas
Floor-to-wall junctions, shower edges, drains and pipe penetrations need continuous treatment within the selected system.
Before tile
Allow the system to cure and test it as required before covering it. Once tiled, diagnosis and repair become much more expensive.
Compare scope, not just price
Ask whether preparation, primer, reinforcing tape, number of coats, flood testing and protection before tiling are included.
