ARDEX 8+9 requires a solid substrate that is clean, dry and free of oils, grease, wax, latex compounds, curing compounds, dust and all foreign matter. Do not install below 50°F (10°C) surface temperature
MIX 1– Caulking Consistency - Mix a small amount of ARDEX 8+9™ to a lump-free caulk-like consistency for filling holes, gaps and joints. Always pour liquid into the mixing container first and then the powder. Working time is approximately 45 minutes at 70°F/21°C.
Crack Isolation- Use MIX 1 to fill around floor or wall penetrations, corner and floor/wall joints and dormant cracks up 1/8” before installing ARDEX SK MESH™. The unused portion of the trowel grade MIX 1 mixture can be blended back with the balance of the remaining powder and liquid for use in the next step, MIX 2
MIX 2– Paint-able Consistency - Mix ARDEX 9 (powder) with one unit of ARDEX 8 (liquid). For best results, mix with an ARDEX T-2 Ring Paddle and a low speed drill.Always pour liquid into the mixing container first and then the powder.Mix thoroughly to obtain a lump-free, pour-able mixture. Coat the entire area evenly with a paint roller or brush and allow thorough drying (30 to 45 minutes). A second layer is required to obtain a waterproof membrane, and must be applied at a 90° angle to the first coat
Tiles can be fixed onto the second coat of ARDEX 8+9™ after one hour at 70°F/21°C.
