PREPARATION:
Before starting ensure that all surfaces are clean, dry and strong enough to support the weight of the tiles and the adhesive.
Remove all loose dust, dirt, oil, grease and other substances likely to affect adhesion.

UNDERFLOOR HEATING:
On concrete floors, the heating element should be embedded in a layer of adhesive and allowed to set prior to fixing tiles, then care should be taken when installing

TILE FIXING:
Add 4 Parts Fast Set Flexible to 1 Part cold clean tap water by weight in a clean mixing vessel. Mix to a smooth creamy consistency either by hand or using a slow mechanical mixing paddle.
Only Mix sufficient adhesive that can be used within 40 mins.
Any adhesive that has started to set must be discarded straight away.
 Apply adhesive to the floor using a notched trowel such that a continuous bed of adhesive between 3mm and 6mm is achieved when tiles are applied.
Adhesive should also be applied to the back of deep studded tiles to cover the studs. Ensure the adhesive is still moist when tiles are pressed into place.
Check there is good transfer of adhesive onto the back of the tile. Clean excess adhesive from the tiles and joints as soon as possible as set adhesive will be difficult to remove later. Always clean all tools after use.

APPLICATIONS:
New Brickwork, Blockwork and Concrete, Must be fully cured and dry prior to tiling. Direct fixing is possible provided the wall is flat.
Screeds and Render: Should be left 14 days prior to fixing.
Existing Glazed Tiles, Unglazed Tiles, Quarry Tiles and Terrazzo:
Ensure tiles are firmly fixed and all surface treatments and contamination is removed. On floors, mix 1 part Granfix Acrylic Bonding and Priming Agent to 1 part ordinary portland cement and apply to floor before tiling
Plaster Surfaces, Ensure surface is free from any loose debris. Prime the surface with 2 neat coats, Granfix Acrylic Bonding & Priming Agent.
Plasterboard: Must be structurally sound with all movement kept to a minimum, and must be able to take the weight of adhesive and tiles (32kg/m2 maximum load). No priming is required
Asphalt, Vinyl Tiles and Sheet Vinyl, Ensure surface is firm, hard and dry. Remove all grease, dust and dirt. Abrade the surface with sandpaper to provide it with a key. Apply 1 coat of Granfix Acrylic Bonding and Priming Agent neat and allow to dry prior to fixing the tiles.
Timber Floors: Must be capable of supporting the weight of the tiles and the adhesive. Surface must be sound, dry and flat. Boards must be firmly fixed to supporting joists prior to overlaying with15mm exterior grade plywood screw fixed at 150mm centres.
Apply 1 coat of Granfix Acrylic Bonding and Priming Agent diluted 1:1 with water prior to fixing.
Anhydrite Floor Screeds: Ensure surface is clean and free from loose matter. Seal the surface with 2 neat coats of GranfixAcrylic Bonding and Priming Agent.
Power Floated Concrete: Ensure surface is clean and free from loose matter. No priming is required, however on very shiny surfaces, acid etching may be required.
