SUBSTRATE QUALITY
- All surfaces must be installed according to manufacturer’s instructions and relevant Australian Standard(s) and be structurally sound, dry, clean and free from movement, oil, grease, wax, sealers, curing compounds, release agents and any other loose or contaminating material. Thoroughly clean old surfaces, or new surfaces that have been treated, prior to tiling.
- Deeply contaminated surfaces must be scabbled / abraded to a clean, sound surface. Expose at least 80% of the original substrate of painted surfaces.
SUBSTRATE PREPARATION
Priming Guide:
| Substrate | Specific requirement | Priming |
| Concrete - wood float finish | Cured a min 6 weeks | Prime with Davco PrimeX or Ultraprime |
| Concrete - steel trowel finish (smooth) | Cured min 6 weeks and free of Laitance (not flaking) | Prime with Davco PrimeX |
| Rendered Brick or blockwork | Cured min 7 days (sound , not drummy or cracked) | Prime with Davco PrimeX or Ultraprime |
| Screed - wood float finish | Cured min 7 days (sound, not drummy or cracked) | Prime with Davco PrimeX or Ultraprime |
| Existing ceramic tiles (provided tile is not sealed) | Securely bonded existing tiles (not drummy) | Prime with Davco Ultrabond or Sika Prep n Prime |
| Other difficult / non absorbent substrates (e.g. contaminated / old flooring adhesive or tile adhesive) | Where not feasible to remove | Prime with Davco Ultrabond or Sika Prep n Prime |

MIXING
- Measure the right amount of clean, potable water into a clean bucket.
- Slowly add the powder into the water while mixing with a mixing paddle attached to a drill. Do not mix by hand.
- Continue to mix for several minutes until a creamy consistency is achieved, free of lumps of powder.
- Allow mixture to stand for 5 minutes, remix then use the adhesive.
Davco® Ceramacrete may require to be remixed during its pot life, do not add additional water.
APPLICATION
Laying the Tiles
- Deposit a quantity of adhesive onto the prepared substrate. Do not apply more adhesive than can be tiled within the open time of the product, usually from a single tile up to around 1m2 at a time.
- Hold the notched trowel at an angle of 60º or greater to the substrate
- Spread the adhesive over the area where tile is to be applied, forming straight rows of adhesive “beads”.
- Where “back buttering” is required, use the straight side of the trowel to apply a thin covering of adhesive to the back of the tile.
- Position the tile on the beaded adhesive and press firmly.
- Move the tile forward and then back at 90º across the direction of the beads to ensure all beads are flattened leaving no voids under the tile. Occasionally lift a tile after placing it to check that the beads are fully compressed, and that sufficient coverage has been achieved (90-100%). Replace the tile.
- After laying a section at a time, remove any excess adhesive from the surface of the tiles and within the grout joint while the adhesive is still wet.
- Allow product to set before grouting
- Allow product to set firmly before return to service
Note: Setting times of adhesive is affected by site conditions, climate and could be faster or slower than specified
CLEANING OF TOOLS
- Clean tools and equipment with water before the adhesive dries.
