SURFACE PREPARATION
All wall and floor substrates must be clean, dry, firm and stable, free of dust,
dirt, oil and grease. Substrates should be strong enough to support the
weight of the adhesive and tiles being fixed (see below for loadings).
For plasterboard 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.

APPLICATION
Apply the UltraTile adhesive to the required thickness (limits 3mm – 20mm) in areas
up to 1m² 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 and external applications 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 of the tiles to allow for grouting
(approx: walls 1mm – 3mm and floors 2mm – 12mm).
Before the tile adhesive sets clean off the excess adhesive from the face of
the tile and grout joints with a clean damp cloth or sponge

No, Tiling on to a wood is not recommended. Tiles being laid on wood are at extreme risk of movement, wood through the elements of the weather will expand and contract dependant on the heat. Therefore the movement of wood with adhesive laid on it will cause the adhesive to crack over time, causing your tiles to break the bond with the adhesive and falling off!

It is always preferable to remove existing tiles however fixing new to old is an accepted method as long as the existing tiles are sound, stable, dry, securely bonded and fixed to a background that is capable of taking the additional weight. Ceramic, porcelain and quarry tiles should be lightly abraded to form a mechanical key degreased and ensured thoroughly clean. For existing vinyl floor tiles only hard and “crunchy” vinyl tiles should be considered to be over-tiled. Be aware that some old tiles of this type contained asbestos so should not be abraded. Do not over-tile onto softer vinyl, quartz or composite tiles.

UltraTile S1 ProFlex SP: Rapid Set Flexible Tile Adhesive can be used for Tile on Tile, but is not recommended!
