The placement method we recommend is similar to the
one used for installing ceramic or stone tiles.
1 - Base preparation
Prepare a perfectly level surface in concrete or self-levelling screed/cement 20mm below the line of the intended floor height (16mm. for 20x20 slabs and 4mm for adhesive).
Wait until the concrete base is dry. This will prevent the formation of white calcium spots that can result from the evaporation of water through the tiles.
2 Placing the tiles
If you choose a traditional carpet style pattern, you must first frame the centre part, and then lay down the border tiles.
Finally, place the outside tiles, which can be resized without disrupting the pattern you have created.
Clean and dampen the underside of the tiles, to help adhesion.
Apply the adhesive mixture evenly to the floor subsurface, using a wide comb. Also apply adhesive to the back of the tile.
Lay down the tiles, and carefully press them into place using your hands. (Do not use a tool, such as a rubber hammer, to set the tile. This could cause micro-cracks to appear in the tile.)
Ensure that the tiles are perfectly level throughout the installation; because mosaic cement tiles cannot be reduced or water polished like marble or terrazzo can.
3 Grout
Grout should be 1mm, wide to let grout cement penetrate. Wider grout disrupts the entire pattern.
Take care to align the tiles so that a regular pattern is maintained throughout the floor.
Grout is filled with liquid grout cement using a spatula.
Immediately remove any excess joint filler with a damp cloth.
Never use pigmentation for the cement joint filler (grout cement). The dye in liquid phase would infiltrate nearest slabs leaving irreversible stains.
4 CLEANING
Immediately clean any cement residue or stains following installation using mop/brush and water, using a pH neutral soap
Never use strong acidic or alkaline products (cement remover, strong detergents) or bleach as they would irreparably damage the tiles.
Paint stains or hard cement spots can be delicately removed with water sanding paper #600 or Scotch Brite
Diamond-tipped saw
Cement step nosing
Wood step nosing
