Preparation

For fixing
All surfaces must be rigid, dry, clean and sound. Wire-brush the surface and then wash down with water and allow to dry. Any voids or defects must be repaired beforehand and allowed to fully set.

For grouting
The tile adhesive must be fully dry/cured. For swimming pools, leave at least 3 days before grouting. Joints must be clean and dry. Ensure that no loose debris, cement or adhesive residue remains.

Caution

Some unglazed, or textured/matt glazed tiles are prone to surface staining. If in doubt, test on a spare tile first. Epoxy resins are very difficult to remove once cured. It is essential that any excess product is removed before it hardens. Epoxy resin can tend to yellow slightly in high UV light conditions or at high temperature.

Mixing

Add all of the hardener component (in the lid) to the resin component (in the base). Thoroughly mix the two components together until a uniform colour and consistency is achieved. Mixing with a slow speed (100 rpm) mechanical mixer is recommended. Do not part mix and do not add water.

Application

Do not use where the temperature is below, or likely to fall below, 10°C during application and curing.

Fixing
Apply the adhesive onto the substrate using a suitable notched trowel, covering up to 1m2 at a time (or no more than can be tiled within 20 minutes. Bed the tiles firmly into the adhesive using a twisting/sliding action. It is good practice to occasionally remove a tile to ensure that a solid bed of adhesive is being achieved. Leave for a least 24 hours before grouting, longer may be required at lower temperatures.

Grouting
Work the grout into the joints with a hard rubber float. Only grout a small area at a time and ensure that the joints are firmly filled and free of voids.

Wipe off any excess grout immediately with the float, working diagonally to prevent dragging grout from the joints. Particular care is required if the joints are wide.

Use a damp emulsifying pad to clean the face of the tiles and emulsify the grout surface before the grout starts to set. Wipe clean with a damp sponge. Failure to correctly finish the grout will give a rough surface, which will be difficult to clean. Finally, clean the tiles surface with water after 12 – 24 hours.

Allowance for movement

Flexible joints should be incorporated to allow for slight movements due to changes in temperature, humidity etc. as indicated by BS5385:
a) where the tiling meets other materials (e.g. floor perimeters)
b) along all internal corners – vertically and horizontally
c) over existing movement joints or changes in background material
d) dividing large tiled areas into bays (every 3 – 4.5 m on walls, 8 – 10 m on floors)
