Application
Mixing ratio
- 4.4–4.8 L of water or Davco Admix 168 per 20 kg bag
- 5.5–6.0 L of water or Davco Admix 168 per 25 kg bag
Open Time
~15 minutes
Consumption
This depends on the level, profile and surface roughness of the substrate, the size of the tiles and the technique of placing (simple placing or "back"-buttering).
As a guide, in kilogram of powder per m² on flat surfaces:
| Tiles size | Coverage | Trowel size |
| Ceramic mosaics, mounted ceramic | ~5 kg/m² | 4 mm x 4 mm notched trowel |
| Ceramic & pavers (10 cm x 10 cm) | ~5 kg/m² | 6 mm x 6 mm notched trowel |
| Quarry tile (15 cm x 15 cm and 20 cm x 20 cm) | ~7.14 kg/m² | 6 mm x 10 mm notched trowel |
| Lugged back and Mexican paver tile | ~10.4 kg/m² | 12 mm x 12 mm notched trowel |
The consumption above may only serve as a guide. It is highly recommended to carry-out trials on site to determine the actual coverage.
MIXING
Pour clean water into a mixing container. Then, slowly add Davco® 168 while mixing. Do not Dump! Mix continuously in a circular motion using a low-speed mechanical mixer until a lump-free, creamy consistency and uniform paste is achieved.
Allow the mix to stand for 5 minutes and re-mix prior to use.
APPLICATION
Davco® 168 is spread onto the substrate using a proper and suitable notched trowel. The choice of trowel should be governed by the size of the tiles, depth of knobs, grooves or ridges on the back of the tiles and the evenness of the substrate.
Use the flat side of the notched trowel to spread the mix onto the receiving surface at approximately 1 m² at a time. Then, use the notched side of the trowel to apply the required amount of the mix in one direction.
Press the tile in perpendicular motion and tapped into position to ensure positive contact with the adhesive and adjust it within 30 minutes.
For tile with grooves or ridges, it is necessary to skim a layer of adhesive / butter coat the back of the tiles. This is to ensure adequate material and a good bond between the adhesive and tile.
Ensure that the adhesive is wet when the tiles are laid. Do not allow the adhesive to skin-over prior to tilling. Should skinning occur, break the skin by re-trowelling the adhesive in the opposite direction.
Do not spread more than 1 m² at any one time. Fix tiles within 15 minutes of applying the adhesive and check the contact by occasionally lifting the tiles. Ensure there are no voids under the tiles and the edges between the tiles are even (lippage) with a consistent joint width.
For external areas, protect from direct sunlight and rain by means of a shelter. It is the user’s responsibility to determine the condition and suitability of all surfaces prior to application.
Grouting
Tile joint grouting should preferably be carried-out at least 24 hours after completion of tiling or until the adhesive has set and dry sufficiently.
Setting may be delayed on dense or impervious surface.
CLEANING OF EQUIPMENT
Clean all tools and application equipments with clean water immediately after use. Hardened or cured material can only be removed mechanically.
FAQ
A C1 tile adhesive is cementitious and has normal setting characteristics. To be categorize as C1, cementitious tile adhesives must meet the tensile adhesion requirement of ≥ 0.5 N/mm² after normal curing, water immersion, heat aging and freeze-thaw cycles (EN 12004).
C1 tile adhesives are normally used as adhesives for ceramic tiles and small format tiles (up to 300 mm × 300 mm) in general conditions.
Sika's product:
Porcelain tiles are more durable (denser and harder), has lower water absorption properties (≤ 0.5 %), and are normally used in areas with high volume of foot traffic (eg. commercial properties, hotels, offices, and retail outlets). Hence, porcelain tiles require a tile adhesive with improved bonding properties (C2).
Sika's product:
Ceramic tiles are easier to use (less brittle, easy to cut and shape), have higher water absorption properties (˃ 0.5 %), and are normally used for walls and floors in housing projects, interior walls of commercial buildings and low volume foot traffic areas. Therefore, ceramic tiles require a tile adhesive with normal bonding properties (C1).
