CEMIX TILE BOND LATEX is modified copolymer latex specially formulated to be used as a primer for porous substrates, wallboard, cement sheets, concrete, screed, timber etc. It can also be used as an additive in place of water to fortify, modify and improve grouts, screeds and certain tile adhesives. It improves workability, adhesion, and resistance to frost and chemical resistance. It also imparts a degree of flexibility and hydrophobicity. Please contact CEMIX Technical support for more details for large commercial applications.
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 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. CEMIX cement screeds/floor levelers must be allowed to cure for a minimum of 7 days. All substrates should be securely fastened and properly supported to eliminate any movement which may cause cracking. For further information, contact the Cemix technical support.
As a Primer prior to adhering Tile Adhesive to substrates: Use undiluted with a roller/brush and apply to the substrate that has to be tiled upon. Some very porous substrates may need 2 coats. All to be tacky (touch dry) before you apply the tile adhesives.
As an additive:
Use as a total water replacement in most powder tile adhesives and grouts. As a standard 1L of this additive is sufficient for 5 Kg of powder. Add CEMIX TILE BOND LATEX to a bucket and slowly add the powder – while mixing with a drill to achieve a lump free consistency as per the directions on the Powder tile adhesive/grout. Can be used as an additive for screeds. Mix 0.5L of CEMIX TILE BOND LATEX with 1kg cement and 3kg sand. 40kg of mixed materials covers 1m2 at 25mm thickness.
Clean tools with water before it dries.
As a primer: 5 to 8 Sq m per litre depending on the porousity of the substrate.
As an additive: 1L for every 5kg of powder adhesive or grout.
12 months – unopened in dry waterproof storage.
