Health and Safety

Directions for Use

Substrate preparation: The surface of the substrate must be cured, mechanically strong, and thoroughly cleaned from all dust, loose particles, oil, wax, etc. BATIMIX Tile Adhesive NS-400 works well on dry surfaces, but can also be applied on lightly dampened ones.

Mixing: One 20-kg bag of BATIMIX Tile Adhesive NS-400 must be mixed with approximately 3.8 liters of clean water. Mixing should preferably be done with a slow-speed electric mixer for a minimum of 3 minutes to get a uniform lump free consistency. During hot weather, use cold water to increase the open time.

Application of the mix: Do not spread more than 1 m² of BATIMIX Tile Adhesive NS-400 at a time. The mortar should be adjusted to the desired thickness using a notched trowel that will give coverage on the tiles back of at least 75% for all indoor walls and floors applications.

Installing the tiles: There is no need to dampen the tiles prior to installation. Apply a firm pressure to ensure good contact with the adhesive. The open time is around 20 minutes at 23 ºC. However, highly absorbent substrate or unfavorable weather conditions (high temperature, drying wind, or strong sun) may shorten this open time quite drastically to just a few minutes.

Constant checks should be conducted to determine if the adhesive is still fresh to the touch and capable of providing good adhesion to the tiles. In case a surface dried skin has formed on top of the adhesive, it is advisable to re-trowel the adhesive with a notched trowel, which would help restoring the open time.

Grouting and protection: Wall joints between applied tiles can be grouted after 6 hours, and floor joints after 24 hours with any appropriate grout similar to BATIMIX Tile Grouts. All tiling made with BATIMIX Tile Adhesive NS-400 must be protected from direct sun and washout for at least 5 to 7 days after application.
