DCI 600 Dispersion Tile Adhesive is a D2TE class dispersion (D), improved (2), non-slip (T), extended open time (E) adhesive. DCI 600 Dispersion Tile Adhesive can be used on walls and floors for thin and medium bed installations of tiles and stone material.
Field of Application
· For interior use
· For installation of ceramic tiles, natural stone, and glass mosaic
· Can be used for tiles up to 45 cm (of longest side)
· For installation of polystyrene boards
· Suitable for damp area applications
COVERAGE / CONSUMPTION
Preparation of the substrate
The substrates must be cured and sufficiently dry, mechanically strong, free from loose particles, grease, oils, paint, wax, etc. The cement substrates must not be subject to shrinkage after installing the tiles. During spring and summer, renders must be cured for at least one week for every centimeter of thickness, and cement screeds must be cured for at least 28 days unless they have been made with DCI special binders for screeds such as Screed 80, Level S10, or with Level S30. Gypsum substrates and anhydrite screeds must be perfectly dry (max. residual moisture 0.5%), sufficiently hard, and dust-free. They must be treated with DCI Grip Primer or Beton Contact, while areas subject to high humidity must be treated with Tile Adhesive Primer. It is not recommended to apply adhesive on substrates until hydraulic shrinkage is complete and the substrate has residual humidity lower than 4%
Preparing the product
DCI 600 Dispersion Tile Adhesive is ready to use the product.
Applying the product
The adhesive is ready to be used. Select an appropriate tool depending on the size of tiles to be installed:
· 6 mm v-notch trowel for mosaics up to 2.5 x 2.5 cm
· 6 x 6 mm or 9 x 10 mm square-notch trowel for larger tile sizes
Clean the substrate using a damp sponge or towel. Apply adhesive to substrate with the flat side of the trowel into the substrate. After this comb the adhesive with the notched side of the trowel, removing the excess product. Spread only as much product as can be tiled while adhesive is wet and tacky, approximately 30 minutes. Press the tiles into the adhesive, and align. Beat or twist all tiles until fully bedded. Check work regularly for full contact between tile back and adhesive.
Installing the tiles
It is unnecessary to wet the tiles before installation; however, the backs are very dusty, they should be wiped in clean water. The tiles are installed under firm pressure to ensure good contact with the adhesive. DCI 600 Dispersion Tile Adhesive open time in normal temperature and humidity is 30 minutes; unfavorable weather conditions like strong sun, high temperature, drying wind, or a high absorbent substrate may shorten this open time, in some cases to just a few minutes. Due to this reason, there must be constant controls to check if the product has formed a skin on the surface or is still fresh to the touch. If a surface skin has formed, the adhesive should be retroweling. It is not suggested to wet the surface of the adhesive when it has formed a skin because a non-adhesive film will be formed instead of dissolving the skin. The adjustment of the tiles, if necessary, should be carried out within 60 minutes following installation, after which time adjustment will become problematic.
Applying the grout
The grout installation can be done after a minimum of 24 hours curing time at 23°C and 50% relative humidity for walls and after a minimum of 24 hours curing time at 23°C and 50% relative humidity for floors. Conditions may change the setting and curing time significantly.
