The kit is suitable for a wide range of applications:

• Shower walls and floors
• Bathroom walls around baths and basins
• Wet rooms
• Power showers
• Areas with underfloor heating or electric undertile heating

It can be applied to various substrates including concrete, cement:sand rendering, plaster, plasterboard, sand:cement screeds, and tile backer boards. The system is designed for internal use and is not recommended for swimming pools, tanks, or as a barrier against rising damp.

One 5kg Dunlop Shower Waterproofing Kit covers approximately 3.5m², which is sufficient for a standard shower enclosure. Multiple kits may be required for larger areas such as complete wet rooms. The coverage is based on applying one coat of Waterproofing Coating to the walls and using the mat on the floor area with two coats. For accurate planning, measure your shower area and add 10% to allow for overlap and waste.

Application follows these simple steps:

• Prepare surfaces by ensuring they are clean, dry and free of dust or loose material.
• Apply Primer to walls and floors with a brush and allow to touch dry (approximately 30 minutes).
• Apply the first coat of Waterproofing Coating with a brush to all corners, wall to floor joints and around pipes.
• Press Waterproofing Tape into the wet coating in these critical areas, ensuring that there are no voids underneath.
• For the floor area, apply one coat of Waterproofing Coating and embed the matting, then immediately apply a second coat over the matting.
• Apply a second coat of Waterproof Coating over the entire area.
• Allow to dry for 24 hours before tiling with a suitable Dunlop tile adhesive such as CF-24 Flexible Tile Adhesive.

Although tile adhesives and grouts provide some water resistance, they are not completely waterproof. Over time, even the smallest imperfections in the grout lines can allow water to penetrate to the underlying substrate. This can lead to serious problems, including

• Structural damage to underlying boards and joists
• Mould and mildew growth behind tiles
• Moisture and water damage to adjacent rooms
• Degradation of plasterboard and other water-sensitive materials
• Costly repairs and potential health risks

The latest Building Regulations (BS 5385) recommend that wet areas should be protected with a suitable waterproofing membrane system. The Dunlop Shower Waterproofing Kit provides this essential protection, ensuring long term durability of your tiled areas and peace of mind for you and your customers.
