Extended info:

SURFACE PREPARATION

All surfaces must be clean, firm, dry, free from all loose matter including dust, dirt, oil, grease, laitance and any other contaminants that may affect adhesion. All substrates should be prepared to provide a rigid and secure base without deflection and suitable to support the intended weight.

The following information provides further details for preparing various common substrates. Unless stated otherwise, any reference to the term “diluted” means 1 part primer mixed with 1 part clean water.

Anhydrite Screeds – The substrate must not leach moisture. Anhydrite screeds must not have a moisture content greater than 0.5% or 75% relative humidity (RH). This can easily be tested by taking moisture readings across the whole surface. It is essential that surface laitance is removed in accordance with the screed manufacturer’s recommendations, followed by vacuum cleaning to remove any loose material, then apply 2-4 neat coats of ROCATEX Acrylic Primer or 2 diluted coats of ROCATEX Ultimate Grip Primer.

Concrete Screeds – Prime with 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer. Substrate curing before tiling can commence is approximately 6 weeks.

Power Floated Concrete – Once cured, power floated concrete should be mechanically abraded (scabbled or shot blasted) to remove any curing agents and open up the surface, followed by vacuum cleaning to remove any loose material, then apply 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer.

Sand & Cement Screeds – Prime with 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer. Substrate curing before tiling can commence is approximately 3 weeks.

Brick/Blockwork – Please note that new brick/blockwork is prone to drying shrinkage and care must be taken. Allow a minimum of 6 weeks before tiling. Prime with 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer.

Gypsum Plaster – The surface should be roughened up using a wire brush or other abrasive tool as this will remove the surface laitance. Ensure surface is clean and free from loose matter and prime with 2 neat coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer. Substrate curing before tiling can commence is approximately 4 weeks.

Cement Based Tile Backer Boards – Must be installed in accordance with manufacturer’s guidelines. Unless stated otherwise, prime with 1 diluted coat of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer.

Existing Tiles & Other Non-Porous Substrates – Apply either 1 neat coat of ROCATEX Ultimate Grip Primer and allow to dry or a slurry coat: 1 part cement adhesive powder to 1 part ROCATEX Acrylic Primer, apply a thin coat with a brush and allow to dry.

Heated Screeds – Heated screeds must be switched off at least 3 days prior to tiling to allow the substrate to cool. Once tiling has been completed allow 1 week before turning the heating system back on. Start with a low temperature and gradually increase at 5°C per day.

MIXING

Mix 20kg of ROCATEX C1F Rapid Grey in a clean mixing vessel with between 4.2 – 4.4 litres of cold clean tap water until a smooth creamy consistency is achieved using a suitable drill with whisk attachment. Mix at a slow speed for a minimum of 2 minutes to ensure that all ingredients (polymers, retarding agents etc.) are dispersed thoroughly throughout the whole mix.

APPLICATION

The mixed adhesive is applied to the prepared surface and then combed through with a suitably sized notched trowel to create a ribbed adhesive bed. The tiles should be pressed into place with a twisting and sliding action to achieve full adhesive to tile transfer.

For tiling to walls in dry internal locations the adhesive contact should be at least 65% of the back of the tile. When tiling to floors and all external situations, or in wet areas such as showers and swimming pools, or when fixing granite, solid bed fixing should be achieved. To achieve a solid bed requires the tiles to be buttered immediately prior to placing into the ribbed bed so no voids are left beneath the tiles. The size of the notched trowel chosen depends on the size of the tile, the surface being tiled, the profile on the back of the tile and the degree of coverage area required. Expansion joints must be installed in accordance with the relevant Part of BS 5385. Test open time by touching the adhesive bed with a finger; if adhesive transfers to the finger a safe bond is assured, if not, the adhesive must be removed and replaced with fresh material. Never add water or powder to a mix that has begun to set. Do not apply at substrate temperatures below 5°C or in conditions of extreme heat. Exterior installations must be protected from direct sunlight, wind or rain.

GROUTING

Leave for a minimum of 3 hours before grouting and or walking on the tile. This time may be extended on impervious surfaces. If completing a swimming pool do not fill for at least 3 weeks after grouting.
