PRODUCT INFORMATION & RESOURCES

DESCRIPTION

CEMIX PRE-MIXED PASTE ADHESIVE is ready to use and does not need anything added to it. Flexible, water resistant & easy to use fixes all indoor tile types. CEMIX PRE-MIXED PASTE ADHESIVE is a pre-mixed, user friendly, white, flexible, anti-slump ceramic tile adhesive recommended for most internal thin bed wall and floor applications over concrete, cement render, fibrous cement sheeting, plasterboard, porous substrates, rendered brickwork, block work and tiling over Cemix approved waterproofing membranes.

SUBSTRATE PREPARATION

The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent the adhesive bonding. New concrete should be left with a wood float finish and sufficiently aged for a minimum of 28 days. Shiny smooth surfaces on old concrete should be acid etched or scabbled. Then use Cemix cement screeds/floor levellers/ renders, they must be allowed to cure for a minimum of 7 days. All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement which may cause cracking. It is recommended that fibre cement sheet tile underlay is initially installed over the timber floor. All substrates that are suitable for tiling should be primed using undiluted Cemix Wall & Floor Primer. Allow this primer to become tacky before application of adhesive. For further information, contact the Cemix Technical support.

MIXING

No mixing required. Just stir and use straight from the container.

COVERAGE

Covers up to 2m2 per Litre.

APPLICATION

All workmanship must be carried out in accordance with AS/NZ 3958.1-2007. Spread the adhesive evenly with a 6mm X 6mm notched trowel for tiles up to 150mm X 150mm and for larger tiles use a 10mm X 10mm notched trowel. Lay the tiles with a good pressure, twisting to ensure good contact with the adhesive. Apply the paste glue to the prepared substrate using the appropriate notched trowel for the size of the tile being laid. Press tiles into the adhesive before it skins over. Do not spread more than 1m² of the paste at a time. At least 80% of the adhesive must be in full contact with substrate and tile. Final bed must not exceed 2mm. If the adhesive skins, re-spread the adhesive. Do not disturb tiles until the adhesive has cured. Allow adhesive to cure for a minimum of 24 – 48 hours (or until tile work has firmed) before grouting. Cemix Pre-mixed Paste Adhesive must not come into contact with water at any stage during cure. Do not tile if temperatures are likely to drop to below 5°C or exceed 30°C. For temperatures below 20°C allow the adhesive to cure for an extended period of time. Occasionally, in order to ensure that full coverage is being maintained, a tile should be removed, the adhesive coverage noted and the tile be re laid accordingly. Once the tiles have been laid, they must not be trafficked upon or disturbed for a minimum of 24 hours at 20°C. Allow 48 hours if temperature will fall below 20°C or tiling over Cemix approved waterproofing membranes, non-porous substrates or tile-on-tile applications. If uncertain check to see if the adhesive has set before grouting. Drying time will be extended if used over Cemix approved waterproofing membranes and bonding or on low porosity tiles.
