Installation

Laying end returns

Step 1:

Start by fixing two end returns to the floor in a corner of the room. (Remove the pipe panel if not required as per your floor plan). This should be done by using suitable screws in the screw holes of the end return panels when fixing to a wood floor or by using Overlay™ adhesive (code PB777) to bond the end returns
to solid floors.

Laying the panels

Step 2:

Clean down the edges of the panel and apply a 3mm bead of adhesive to the top edge. Then, lay it ensuring you line up the grooves in the panel with those in the end returns. Continue to lay the first row of panels gluing each joint to
achieve a secure installation.
When gluing the ends, ensure there is no residual glue in the pipe
grooves and use short lengths of pipe to help with panel alignment.

Step 3:

When you get close to end of the first row fit two end returns against the wall as in step 1 and if necessary cut an Overlay™ panel to fit and complete the first row.

Cutting the panels

Panels can be cut using a hand saw or jigsaw at a low speed. (Cutting these panels will generate dust so should either be done outside or in a ventilated room. Ensure you wear a particle mask.)

Step 4:

Once you have completed the first row begin the process again, gluing the ends and sides of each panel, staggering the panels in the second row in a brickwork pattern and continue until the room is complete.

Laying the pipe

Step 5:

Starting from your manifold position and allowing enough pipe for connections lay the pipe into the grooves of the OverlayTM panel in accordance with your plan.

Finishing

Using a floor filler/grout fill any gaps and voids, and fill
around any pipework.

Tiles can be laid directly on to the Overlay™ panels or a cover board can be fitted prior to tiling. When tiling directly over Overlay™ panels, use a sealant with flexible adhesive and grout.

If fitting solid wood floors they can be discreetly screwed through the tongue and go directly into the Overlay™ panel avoiding pipe circuitry, to minimise movement in the floor covering.
