• Waterproofing walls and floors in bathrooms and shower cubicles before laying ceramic tiles, natural stone and mosaic.
• Waterproofing kitchen walls and floors, and work tops before laying ceramic tiles and natural stone.

• Do not apply Mapegum WPS if the temperature is lower than +5°C.
• Create sloping surfaces where necessary to avoid the formation of puddles of water.
• Do not apply Mapegum WPS on damp cementitious substrates or on substrates which are subject to rising
• damp.
• Do not use Mapegum WPS on surfaces continuously immersed in liquid such as swimming pools, fountains, storage tanks, etc. Use Mapelastic or Mapelastic Smart for these types of application.
• Do not use Mapegum WPS to cover cracks.
• Mapegum WPS must be protected from abrasion caused by pedestrian traffic by installing ceramic tiles or stone material.
