CEMIX FAST SET TILE ADHESIVE is a one part, highly flexible, polymer engineered, water resistant, fibre reinforced grey cement based adhesive. With a rapid setting time of 2 hours it is recommended for high trafficked commercial /residential areas when urgency of completed tile fixing is required. Suitable for use in internal/external wall and floor applications, including, bathrooms, toilets, laundries, kitchens, decks, and over existing tiles* plus totally immersed conditions such as swimming pools. Suitable over concrete, cement renders, screeds, fibrous cement sheeting, plasterboard and Cemix waterproofing membranes. In conjunction with CEMIX FLOOR SELF LEVELLER, it can be used for under tile heating applications. When using with translucent tiles, the colour of the adhesive should be taken into consideration.
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 7 days. CEMIX floor levellers must be allowed to cure for a minimum of one day. All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement which may cause cracking. CEMIX FAST SET TILE ADHESIVE is suitable for tiling over timber floors, provided that a fibre cement sheet tile underlay is initially installed over the timber floor. *Certain non-absorbent/impervious substrates i.e. tile over tile, metals, vinyls and the like, should be primed using CEMIX BOND ALL SUPER PRIMER. For all other substrates prime surface with CEMIX TILE BOND LATEX PRIMER & ADDITIVE brushed on straight from the container. Allow to become tacky before tiling. For further information, contact CEMIX Technical support 0800 ASK CEMIX.
Movement joints must be incorporated at the design stage and in accordance with current AS 3958.1. Movement joints should go right through the tile adhesive bed to the background and be kept free from dirt and adhesive droppings. Movement joints must not be less than 6mm or greater than 10mm wide.
Note: Do not aerate the mix by stirring over vigorously or for too long. The mix should be stiff enough to keep its shape when spread with a notched trowel.
All workmanship must be carried out in accordance with AS3958.1. It is recommended to always spread the adhesive both over the substrate and the tile with the flat edge of the trowel to ensure that good contact is achieved. Then spread extra adhesive evenly to substrate with suitably sized notched edge side of trowel. Now install the tiles with a good pressure, twisting to ensure good adhesive contact between substrate and tile. For wall tiling, a minimum final bed thickness between 3mm to 5mm is recommended, whilst for floor tiling a minimum final bed thickness between 5mm to 10mm is recommended. Do not spread more than 0.5m² of adhesive at any one time as skinning may occur affecting final adhesion. Ensure that the tiles are fully supported with the adhesive with no voids. 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 2 hours at 18 ºC. Cure time will be delayed if temp is below 18 ºC. Please watch Cemix How To Tile Video on Youtube.
Prior to grouting, remove excess adhesive from the tile face and between the tiles. Grouting may be undertaken 2 hours after tile fixing. Allow grout to dry per grout manufacturer recommendations. Allow joint widths of 1.5mm to 5mm for walls and 3mm to 8mm for floors as per AS3958.1-2007. Thoroughly clean the surface of the tiles to remove all residue prior to the grout drying.
Varies according to trowel size and substrate condition from approximately: 2m² per 5kg pail using a 6mm notched trowel and 1.25m² per 5kg pail using a 10mm notched trowel.
