Taurus Wet Room Tray Former Installation Kit | Fix-KST Adhesive, Pro-Seal, Waterproof Tape & Internal Corners

What's in the Kit

• Fix-KST Fixing Adhesive — 5kg Low-shrink, flexible, fast-set cementitious adhesive for bedding the tray former to the subfloor. Suitable for timber joist floors (primed) and concrete slabs. 5kg covers approximately 2m² of screeded bedding at standard depth. For large format trays (e.g. 1600×900mm or larger), additional Fix-KST will be required — purchase separately.
• Pro-Seal Premixed — 500ml Ready-to-use waterproof sealing compound applied beneath and over the waterproofing tape. Seals the tape firmly to the tray perimeter and subfloor junction, completing the waterproof barrier at the most vulnerable point of the installation.
• Waterproof Tape — 5m Flexible waterproof fabric tape for sealing the perimeter joint between the tray former and the surrounding floor or wall boards. Applied in Pro-Seal compound. Bridges the movement joint at the tray edge and prevents water tracking under the tiled surface.
• 2× Waterproof Internal Corners Pre-formed waterproof corner pieces for use at the internal 90° angles where the tray former meets the wall boards. Eliminates the need to cut and fold tape around corners — a common point of weakness — and ensures a consistent, fully sealed junction in each corner.
• Wood Floor Primer — 1L Applied to timber subfloors before bedding the tray former. Reduces porosity of the timber surface and improves adhesion of the Fix-KST bedding adhesive. Essential on timber joist floors — do not skip this step. Covers approximately 10m².
• 50mm Paintbrush For applying the wood floor primer and working Pro-Seal compound under and over the waterproof tape edges.
• Protective Gloves For use when handling Fix-KST adhesive and Pro-Seal compound.

Why Use a Dedicated Installation Kit?

A wet room tray former that is not correctly bedded or waterproofed at its perimeter is one of the most common causes of wet room failure. Water tracking under a tray former — through an inadequately sealed perimeter joint, through an incorrectly primed timber subfloor, or through a poorly adhered bedding layer — can cause extensive structural damage that is expensive and disruptive to remedy. The Taurus installation kit provides all the correct, system-matched consumables in the right quantities for a single tray installation, ensuring the installer does not substitute incompatible materials or omit critical steps.

Using system-matched products throughout — Fix-KST for bedding, Pro-Seal for tape sealing, and pre-formed internal corners — also provides a consistent set of material properties across the installation. All components are formulated to work together, with compatible cure times, flexibility ratings, and adhesion characteristics.

Key Benefits

Installation Overview

The following sequence covers the key steps for installing a Taurus wet room tray former using this kit. Always refer to the full installation instructions supplied with the tray former and this kit before starting work.

• Prepare the subfloor. Ensure the subfloor is clean, level, and structurally sound. Check for any deflection in timber floors and address with additional strutting or noggins if required. Remove any dust, grease, or debris.
• Prime timber floors. On timber joist subfloors, apply the included Wood Floor Primer using the 50mm paintbrush. Allow to dry fully before proceeding. Do not prime concrete floors — this step applies to timber only.
• Mix and apply Fix-KST bedding adhesive. Mix the Fix-KST to a firm bedding consistency in the supplied tub. Apply to the subfloor in the tray footprint, combing with a notched trowel to create a full, even bed. Also apply to the underside of the tray former if required by the tray installation instructions.
• Bed the tray former. Lower the tray former into position and press firmly into the Fix-KST bed. Check level and alignment. Adjust before the adhesive starts to set. Allow to cure fully before applying tape and tiles — do not rush this stage.
• Apply Pro-Seal to the tray perimeter. Using the paintbrush, apply Pro-Seal compound along the full perimeter of the tray where it meets the surrounding floor and any wall boards. Work Pro-Seal under the tape as it is applied.
• Apply waterproof tape. Press the waterproof tape into the Pro-Seal compound along all straight perimeter runs, overlapping onto both the tray surface and the surrounding floor/wall substrate. At each internal corner, bed the included pre-formed corner pieces first, then overlap the straight tape runs onto them.
• Apply Pro-Seal over tape. Brush a coat of Pro-Seal over the full surface of the applied tape, ensuring all edges are fully sealed. Allow to cure before tiling.
• Tile. Once fully cured, tile the tray and surrounding floor with a C2-rated flexible tile adhesive. Maintain a movement joint at the tray perimeter — do not grout this joint; fill with a sanitary-grade silicone sealant.
