-- 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

Is a large water underfloor heating kit enough to heat an entire floor of my home?
Yes, large kits are designed for whole-floor coverage, making them perfect for open-plan living areas or an entire storey in a house.
What room area does the 100m² Ultra Warm Tile Direct system cover?
The 100m² Ultra Warm Tile Direct system covers a floor area of up to 100 square metres, making it ideal for open-plan spaces or multiple adjoining rooms with a combined area of 100m². The system is supplied with pipework and panel components optimised for this 100m² coverage, ensuring you avoid under-sizing or overspending by choosing a properly matched kit.
Which floor types are compatible with this 25mm panel system with 150mm pipe centres?
As the 100m² Ultra Warm system uses 25mm thick routed insulation panels with pipes laid at 150mm centres, it is compatible with solid floor substrates like screed or concrete and supports direct tile finishes. It’s also suitable in some floating floor contexts (depending on manufacturer guidance), due to its moderate build-up height, enabling efficient heat transfer to finishes such as ceramic or porcelain tiles while preserving usable floor height.
