- Waterproofing membrane for floors and walls.
- Coatable waterproofing membrane.
- Indoors and outdoors.
- Can be applied by trowel or roller.
- Solvent free.
- Impact resistant.
- Filling capacity.
Two-component liquid waterproofing membrane for waterproofing walls and floors to be covered with any type of ceramic tile, formation of joints in corners, half-rounds and integration of pipes and drains in bathrooms.
Levelling and great capacity to fill irregularities and cracks in the substrate.
Under the tiles, it is perfectly resistant to the aggression of areas in permanent contact with water, such as in showers, bathrooms, shower areas above bathtubs and sanitary rooms in public and industrial areas with drains.
On terraces and balconies, it waterproofs and protects the substrate from moisture and efflorescence, provided that Ardex 8+9 is coated with ceramic tiles or a paint finish.
Suitable substrates are cement and concrete screeds.
It does not replace bituminous and asphalt membranes according to DIN 18 195.
ARDEX 8 + 9 is a two-component assembly: ARDEX 8, an acrylate dispersion, solvent-free and with a specific weight of approx. 1.0 kg/l and ARDEX 9, a cement-based powder with a specific weight of approx. 1.2 kg/l. Both components are mixed together in a 1:1 ratio.
Once dry, the ARDEX 8 + 9 waterproofing membrane is watertight and highly mouldable. It does not colour cementitious mortars used for sealing the joints of ceramic tiles.
With consistency for roller application: 20 kg ARDEX 8 : 20 kg ARDEX 9 (1:1).
With trowel consistency: 14 kg ARDEX 8 : 20 kg ARDEX 9 (1:1.5)
Density of fresh mortar:
Consistency for roller application: approx. 1.3 kg/l
With consistency for trowelling: approx. 1.4 kg/l
Consistency for roller application (2 coats): approx. 0.75 powder + 0.75 dispersion approx. 1.5 kg mixture/m2
Consistency for trowel application (for 3 mm layer): approx. 2.5 kg powder + 1.70 kg dispersion = approx. 4.20 kg mixture/m2
Approx. 1.6 kg powder per litre mortar.
Open workability time (20°C):
Approx. 3/4 hour
Approx. 2 hours
Hazardous Material Classification:
ZP 1 (dust)
ARDEX 8: in 5 and 20 kg cans
ARDEX 9: in 5 and 20 kg bags
Approx. 12 months in dry places and in its original closed container.
