-- Remove all contaminants, dirt, grease etc from the substrate and make dust free.
-- Loose lay the boards across the floor and number the boards on the upper face to identify position of each board, making sure the pipework runs are calculated correctly to reach manifold position.
-- Uplift the numbered boards and prime the underside of the boards with Ultra Floor Prime-IT MSP bonding primer. This should be applied by brush or roller in a thin film. Allow to thoroughly dry to a clear green film ensuring primed face does not come into contact with other boards, walls or subfloor until it is ready to be bedded.
- -Drying time will depend upon ambient conditions but is typically between 1 and 4 hours.
-- Whilst the primer on the boards is drying commence with priming of the substrate using UltraFloor Prime-IT MSP. The primer should be diluted 3 parts water to 1 part primer and allowed to fully dry.
-- Apply flexible tile adhesive to the subfloor using a notched trowel to give a minimum 3mm adhesive bed. Bed the boards, primed side down, into the adhesive and ensure compression of adhesive ridges, ensure full compression of the adhesive to give a void free full adhesive bed. Additional use of  screws and washers is recommended over timber substrates where needed, fixed at every 300mm. Allow to cure for approximately 4 hours to ensure the adhesive has gone through its initial set before carrying out any further works.
-- Pipe work may be fitted into the boards once they are all secure. Where possible this is best left until the following day. It is recommended that the pipe system is checked for leaks and correct water pressures prior to tiling over.
-- Prime the upper face of the boards with Ultra Prime-IT MSP bonding primer. This should be applied by brush or roller in a thin film. Allow to thoroughly dry to a clear green film, (approx 1-4 hours).
-- Apply Ultra Floor Level-iT 2 two part smoothing compound over entire floor area, making sure all voids and gaps are completely filled, the levelling compound should encapsulate the whole floor and cover the board with a 5mm layer on top.
-- Allow to cure for 24 hours prior to carrying out any tiling. Cold and/or humid atmospheres will delay the curing of Level-iT 2 so allowances should be made accordingly.
-- Prime the cured Level-iT 2 using Ultra Floor Prime-IT MSP diluted with 3 parts water to 1 part primer. Allow to thoroughly dry.

Frequently Asked Questions

What floor area is the 18mm Solid Floor Tile Direct 80m² System suitable for?
The 18mm Solid Floor Tile Direct 80m² System is designed for coverage of up to 80 square metres, making it an ideal choice for a large living or dining area, or several connected rooms. Ensure the combined floor space adds up to 80 square metres to maximise effiency and even heat distribution.
What type of sub-floor and finish is the 18mm Solid Floor Tile Direct 80m² System compatible with?
The 18mm Solid Floor Tile Direct 80m² System is built for installation onto a solid base, such as a concrete or screed sub-floor, using panels that are 1 ,200 mm × 600 mm × 18 mm deep and are pre-grooved to take 12mm pipe at 150mm centres. It specifically supports a tile or stone finish installed directly above the system, allowing efficient heat transfer to the surface. Due to the 18mm build-up, it’s best suited where minimal floor height increase is preferred.
Why is the 150mm pipe centres spacing important in the 18mm Solid Floor Tile Direct 80m² System?
The spacing of 150mm centres for the 12mm pipe in the 18mm Solid Floor Tile Direct 80m² System ensures that heat is evenly distributed across the full area of up to 80m². With the pre-grooved insulation panels and carefully designed pipe layout, this spacing helps avoid cold spots, maximises comfort, and supports efficient system performance when laid as specified.
