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. New timber should be given time to find equilibrium with its surroundings.
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 – Substrate curing before tiling can commence is approximately 7 days. Do not prime green screed. Cured screed should be primed with 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer.
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 – Substrate curing before tiling can commence is approximately 24 hours. Do not prime green screed. Cured screed should be primed with 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer.
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.
Plaster Boards – Skimming is not required. Prime with 2 diluted coats of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer.
Plywood – Must be a minimum thickness of 15mm, exterior grade, screwed down at 300mm centres and all joints must be supported. Prime the surface with 1 diluted coat of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer.
Tongue & Groove Boards/Floorboards – Must be dry, rigid and securely fixed and screwed to joists at every 300mm. Prime the surface with 1 diluted coat of ROCATEX Acrylic Primer or 1 diluted coat of ROCATEX Ultimate Grip Primer.
Chipboard – Must be a minimum thickness of 22mm, moisture resistant quality, screwed down at 300mm centres and all joints must be supported. Apply 1 neat coat of ROCATEX Acrylic Primer or ROCATEX Ultimate Grip Primer to all exposed edges and joints and then apply either 1 neat coat of ROCATEX Ultimate Grip Primer or a slurry coat to the surface: 1 part cement adhesive powder to 1 part ROCATEX Acrylic Primer, apply a thin coat with a brush and allow to dry.
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.
Metal: Prime the surface with 1 neat coat of ROCATEX Ultimate Grip Primer and allow to dry.
Flooring Grade Asphalt – Ensure the surface is in good condition and there are no signs of debonding and/or hollowness. Apply 1 neat coat of ROCATEX Ultimate Grip Primer and allow to dry.
Epoxy Damp Proof Membranes – Apply 1 neat coat of ROCATEX Ultimate Grip Primer and allow to dry.
Underfloor Heating – Existing underfloor heating 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.
When tiling on to new electric underfloor heating, we recommend the use of a suitable self levelling compound to encase the heat mat, for example ROCATEX Fibreflow Rapid Flex Leveller. Once tiling has been completed allow 1 week before turning the heating system on. Start with a low temperature and gradually increase at 5°C per day.
