Imperboard shower tray installation

Solid Concrete Floors

Cut a channel deep enough to take a BS standard 50mm pipe along the floor from the position of the drain body to a suitable exit point. See figure 1. 

cut concrete for wet room tray fitting

The cut-out for the drain body needs to be 200mm square and 80mm deep. See figure2. cut out for wet room drain measurements
Connect the drain body to the 50mm outlet with solvent weld in the usual way. We recommend that you use the plastic cap (as illustrated in figure 6) at this stage as a means to prevent dirt entering the drain body. (Always check for leaks before final installation of the Imperboard shower tray). See figure 3. fit drainage for wet room
Install the connected drain body and pipe into the channel and support with mortar at the correct height and fall. (The top of the drain body including the washer should be level with the surrounding floor). See figure 4. put the drainage parts for the wet room in the trench
Using a 10mm notched trowel apply the cement-based, flexible tile adhesive to the floor and lay the tray in place using a tamping motion to ensure no voids remain under the tray. See figure 5. Using a 10mm notched trowel apply the cement-based adhesive
Using the plastic cap, screw the upper section of the drain body into the lower section through the tray. Care should be taken not to disturb the tray, but realign if necessary. See figure 6.  Using the plastic cap, screw the upper section of the drain body into the lower section through the tray
Build up the surrounding floor area with the correct thickness of Imperboard as required using flexible, cement-based tile adhesive. See figure 7. Build up the surrounding floor area with the correct thickness of Imperboard as required using flexible, cement-based tile adhesive.

 

Timber Floors

Cut out the required section of flooring. See figure 1. Cut out the required section of flooring
All Imperboard trays should be supported between joists. Build a support for the drain body exactly 80mm below the surface of the surrounding floor. See figure 2. All Imperboard trays should be supported between joists.
Fix a batten 18mm (or the depth of the flooring used) below the top of the joists. See figure 3. Fix a batten 18mm (or the depth of the flooring used) below the top of the joists
Connect the drain body to a 50mm BS standard waste pipe with solvent weld in the usual way. (Always check for leaks before final installation of the Imperboard tray). Cut the timber to fit between the joists and screw onto the new battens which must be securely fixed to the sides of the joists. See figure 4. Connect the drain body to a 50mm BS standard waste pipe with solvent weld in the usual way.
The middle section needs a keyhole shape cut out for the waste. This should be 10mm bigger than the drain body. See figures 5 & 6. The middle section needs a keyhole shape cut out for the waste. This should be 10mm bigger than the drain body
Using a 10mm notched trowel apply the flexible, cr- ment-based tile adhesive to the floor then fix the shower tray in place using a tamping motion to ensure no voids remain underneath. See figure 7. Using a 10mm notched trowel apply the flexible, cr- ment-based tile adhesive to the floor then fix the shower tray in place using a tamping motion to ensure no voids remain underneath
Screw the upper section of the drain body into the lower section through the tray, being careful not to disturb the tray. Realign as necessary. See figure 8. Screw the upper section of the drain body into the lower section through the tray, being careful not to disturb the tray. Realign as necessary.
Build up the surrounding floor area with the correct thickness of Imperboard as required using flexible, ce- ment-based tile adhesive. See figure 9. Build up the surrounding floor area with the correct thickness of Imperboard as required using flexible, ce- ment-based tile adhesive.

 

Imperboard Tanking Kit

 

Imperboard Tanking Membrane is a styrene butadiene latex based liquid applied membrane that offers a simple waterproofing method for absorbent substrates in wet areas.

Designed for use before laying ceramic, porcelain, natural stone and mosaic tiles.

Ensure the application area is clean and dry. Tape all corners with Imperboard Tape. Overlap the tape in the corners

Tape all corners with Imperboard Tape 

Apply a coat of Imperboard Tanking Membrane to cover the tape. If required apply a second coat after one hour. Allow to dry for 2-4 hours before tiling Apply a coat of Imperboard Tanking Membrane to cover the tape.
