  • Rock-Tite Mortar Exterior Porcelain and Stone System
  • Rock-Tite Porcelain Primer
  • Rock-Tite Brush-in Grout

Preparation

  1. Dig out the area to be tiled, making sure it is stable
    It should be deep enough to allow for a compacted hardcore depth of 75mm to 150mm for patio flags/natural stone. Or 100mm to 150mm for porcelain tiles.
  2. Create a fall
    Set out the area to be tiled using a horizontal level line and a second sloped line to create a fall. The area should fall away from any property at a ratio of 25mm over a 1.5m length.
  3. Compact Type 1 or MOT grade hardcore making sure it is rigid and stable

Laying

  1. Use a mechanical mixer to mix Rock-Tite Mortar at a ratio of 3.75 litres water to 25kg powder
    Only mix enough enough to be used within the pot life of 60 minutes.
  2. Lay a solid bed of mortar
    A mortar thickness of not less than than 25mm may be used on to hardcore which is not less than 100mm deep.
  3. Pour cold water into the graduated mixing bucket to the correct level
  4. Gradually add the required amount of Rock-Tite Porcelain primer powder
  5. Mix the primer to a smooth lump-free slurry
    Only mixed enough to be used within the pot life of 60 minutes.
  6. Apply Rock-Tite Porcelain Primer to the back of the tiles using a brush or roller
    The primer must still be wet when laying into the mortar.
  7. Lay the tiles into the mortar
    Leave at least a 3mm joint width between the tiles.
  8. Once finished, allow to dry for 24 hours before grouting

Finishing

The ground must be free-draining and the sub-base permeable.

  1. Wet the surface of the tiles and keep them moist throughout
  2. Make sure the joints are clean and dust free
  3. Brush the Rock-Tite Grout into the joints at 45-degrees using a long-handled brush
    Keep applying until the joints are filled and void free. Don’t allow the surface to dry out. Excess grout can be put into a tub and covered with water to at least 50mm above its surface, ready for use.
  4. Compact the joints and finish them with a jointing tool
    If voids appear, refill and refinish then brush off any excess grout.

Foot traffic is permitted within 24 hours.
