Ready-to-use, ultraquick drying, flexible liquid membrane for internal and external waterproofing

Where to Use

To form waterproofing layers before applying ceramic, stone and mosaic coatings in:

• Balconies and terraces
• Bathrooms and shower cubicles
• Laundry rooms
• Saunas and damp environments in general.

Mapelastic AquaDefense may be applied on:

• Concrete
• Cementitious screeds and screeds made using special binders (Topcem, Topcem Pronto,Mapecem or Mapecem Pronto);
• Plasterboard (for internal applications only)
• Existing coatings in ceramic, terrazzo and stone
• Cementitious render.

Advantages

Mapelastic AquaDefense is supplied ready to use.

• Mapelastic AquaDefense is a rapid product:
  – resists rainwater 1 hour after applying the first coat and 3 hours after applying the second coat.
  – ceramic may be bonded after 4 hours
  (at +23°C and 50% R.H. when applied on a dry screed with less than 3% residual moisture).
• Mapelastic AquaDefense is elastic: at +23°C it has 3.2 mm crack-bridging capacity without reinforcement.

Technical Characteristics

• Mapelastic AquaDefense is a totally solvent-free, ready-to-use, ultra-quick drying, one-component light blue, synthetic resin based paste in water dispersion.
• Mapelastic AquaDefense is easy to apply using a long-haired roller, brush or trowel on horizontal, sloping and vertical surfaces.
• Mapelastic AquaDefense dries very quickly to form a flexible membrane without a sticky surface. It is resistant to light pedestrian traffic after just 3 hours and forms an excellent grip with all types of adhesive for laying ceramic, stone material and mosaic of all kinds.
• The flexible nature of Mapelastic AquaDefense helps it withstand normal movements caused by expansion and shrinkage of the substrate due to temperature variations and vibration.
• Tiles laid on floors waterproofed with Mapelastic AquaDefense by using C2F-class MAPEI adhesives (such as Granirapid, Elastorapid, etc.) and grouted with Ultracolor Plus may be opened to pedestrian traffic within 12 hours of starting the work.
• Mapelastic AquaDefense is resistant to water, lime-water (ph > 12), and detergents commonly used for cleaning residential environments.

Recommendations

• Do not apply Mapelastic AquaDefense if the temperature is lower than +5°C.
• Mapelastic AquaDefense must always be covered with ceramic, mosaic or stone.
• Do not apply Mapelastic AquaDefense on cementitious substrates or on substrates with residual humidity higher
  than 3% and recurring rising damp.
• Do not apply Mapelastic AquaDefense on crumbly cementitious substrates, old floors which are not well bonded to the substrate or surface treatments which impede a good bond.
• Do not use Mapelastic AquaDefense to cover cracks.
• Protect the surface from rain for at least
  1 hour after applying the first coat and
  3 hours after applying the second coat
  (times refer to +23°C and 50% relative humidity of the air when the product is applied on dried screeds with a residual moisture lower than 3%).
