APPLICATION INSTRUCTIONS

All substrates shall be installed as per manufacturers instructions, fit for purpose and designed to handle the loads of a Tile or Stone system.

  • Substrate Deflection: All Substrates under loads must not exceed L/360 for tile and L/450 for Stone.
  • Substrates must be properly cured, structurally sound, free from loose or friable particles, clean, dry and free from contaminates such as dust, dirt, oil, grease, curing compounds, crystaline sealers, laitance, or effloresence.
  • Dependant on the substrate condition and contamination to be removed from the surface, perform adequate scarification, or blast cleaning in order to remove all traces of any materials that could reduce the product adhesion to the substrate.
  • Refer to Sikalastic®-1KMY PDS for further details.

Floor Tiling may commence after;

Porous Substrates

After 2-3 days

Non Porous Substrates

After 2-3 days

*Note: substrate porosity, enviroment, temperture, humidity and conditions will impact drying and curing times.

EQUIPMENT

Slow Speed Mixing Drill (Max 500RPM)

SUBSTRATE QUALITY

Concrete Floors: Allow 28 days for concrete to cure. Concrete shall be left with an open surface, steel trowel finishes are generally acceptable if they accept water penetration. Wood float finishes are preferred where possible.

Cement mortar beds / Screeds: Mortar bed / Screeds must be installed as per AS ISO 3958.1,2007. Mortar beds must be a minimum 24 hous old at 23 °C and 50 % r.h.

Sheeted substrates: All boards / Underlays must be installed as per manufacturers instructions and specifically designed for tiling.
