Description
Ultra Tile ProFlex S2 ES Standard Set Tile Adhesive is a single part, standard setting, flexible, fibre reinforced adhesive for wall and floor tiles. It is specially formulated with enhanced adhesion and flexibility, making it ideal for areas where slight movement or vibration can occur. Classified as S2 in accordance with EN12004 it has the highest level of deformation for exceptional tolerance to movement.
Ultra Tile ProFlex S2 ES Standard Set Tile Adhesive is supplied in white, in 20kg bags.
Ultra Tile ProFlex S2 ES has a unique blend of polymers giving it superior bonding and slip resistance performance in combination with an extended range tile types in wet or dry conditions. Ideal for interior & exterior depending upon temperature and substrate. Please Note: Porous natural stone tiles need to be checked for compatibility to avoid staining.
Surface Preparation:
All wall & floor substrates must be clean, dry, firm and stable, free of dust, dirt, oil and grease prior to applying Ultra Tile ProFlex S2 ES. Substrates should be strong enough to support the weight of the adhesive and tiles being fixed (see chart on datasheet for loadings). For plaster board and plaster finishes that have been painted and are showing a weak or flaky surface finish then mechanical sanders or hand sanding blocks are generally used to remove the film. However for the likes of floor screed surface contamination, adhesive residues and weak surface laitance or even smooth dense floors such as power floated concrete, these will require a more heavy duty scarifying using specialist flooring equipment to remove the surface of the substrate to ensure the substrate is sound, stable and has a rough open texture. To encourage best adhesion to the substrate it is advisable that prior to applying adhesive that substrates are primed (please see priming section below).
Remember – sanding or mechanical abrasion of any surface will leave powder deposits which require thorough removal by suitable vacuum equipment to provide a clean dust free surface. Failing to remove fine powder deposits and weak surfaces is a common reason for de-bonding of tile adhesive and primer from the substrate. Using a wet sponge to clean down a wall or floor of dust deposits only serves to spread it around, it is therefore advisable to vacuum thoroughly prior to use of wet sponge.
Priming:
Ultra Tile ProPrimer has been specifically developed to be used as a primer for use with cementitious tile adhesives to provide improved sealing and bonding properties for a variety of substrates.
Mixing:
Once the substrate has been prepared, continue with the tiling installation. Ultra Tile ProFlex S2 ES should be added slowly to clean water in a suitable clean mixing tub and mixed thoroughly using a drill/mixer and paddle to give a slump free, easily worked mortar consistency. Once mixed the mortar is immediately ready for use and has a pot life of approximately 120 minutes at 20°C. Do not remix or re-wet/dilute mixed product which has aged and is starting to thicken or set.
Mixing Ratio: 20kg unit requires 5.0L of water.
Application:
Apply Ultra Tile ProFlex S2 ES adhesive to the required thickness (limits 3mm – 20mm) in areas up to 1m at a time. For internal walls use a notched trowel to the following notch dimensions to provide solid rib lines:
Mosaic tiles: 3mm x 3mm at 6mm centres
General wall tiles: 5mm x 5mm at 10mm centres
General floor tiles: 8mm x 8mm at 16 mm centres
For floors & external applications using Ultra Tile ProFlex S2 ES we advise to use the solid bed method. This involves applying a uniform bed of adhesive to the floor and “buttering” the back of the tile with the same adhesive. When the tiles are bedded with a twisting action, pressing firmly down it ensures 100% contact is made with both the floor and the tile. When fitting tiles leave spaces between each the tiles to allow for grouting (approx: Walls 1mm-3mm & Floors 2mm-12mm).
Before Ultra Tile ProFlex S2 ES adhesive sets clean off the excess adhesive from the face of the tile and grout joints with a clean damp cloth or sponge.
Grouting:
Leave the installed tiles for a minimum period for at least 18 hours to set hard before grouting and/or walking on the tile. This time may be extended on impervious/non-porous substrates. It is also dependent on temperatures and conditions. Always check and ensure that Ultra Tile ProFlex S2 ES Standard Set Tile Adhesive has set hard before grouting. Ultra Tile ProGrout Smooth and ProGrout Flexible are available for use in a variety of colours.
