Application of Tilesafe Membrane

Prior to the application of each length of Tilesafe Membrane, remove the plastic film from the underlying Tilesafe Reinforcing Tape.

Apply pre-cut lengths of Tilesafe Membrane to walls first, applying as vertical drops and terminating at the floor/wall junction (overlapping the reinforcing tape by 75 mm).

Tilesafe Membrane should be butt jointed rather than overlapped. All butt joints in the membrane should be positioned over the previously applied reinforcing tape, ensuring a gap of 2-3 mm is maintained which should be subsequently filled by the Tilesafe jointing compound. Continue in the same manner for floors, cutting membrane around any pipe entries, taking care not to damage the reinforcing tape below.

Application of Jointing Compound

Using an applicator gun, apply Tilesafe Jointing Compound at butt joints, pipe entries and at all wall to wall and wall to floor interfaces.

The compound should be gunned in to the previously formed 2-3 mm channels, which should be fully filled.

Tooling can be carried out with a profiling tool within approximately 10 minutes of application.

Allow Tilesafe Jointing Compound to cure overnight before applying tile adhesive.

The membrane surface and joints should be thoroughly inspected prior to tiling. Particular attention should be paid to the pipe entries, ensuring seals have not been damaged by following trades between application and tiling. If necessary a re-application of Tilesafe Jointing Compound can be made.

The plastic release film is left in place until immediately prior to tiling.

Application of Tile Adhesive and Tiles

Prior to application of the tile adhesive, which must be rapid-set, flexible and waterproof, the plastic backing film must be removed.

Application of tiles to Tilesafe is essentially the same as normal tiling. There are a few points to consider to ensure satisfactory application:

• If a batten is to be used for tile alignment, this should be secured to the wall through the backing release film, not after this has been removed.
• Remove the release film only from those areas where tile adhesive is to be immediately placed.
• Leave the backing film in place on the floor areas of Tilesafe while tiling the walls.
• Silicone sealant will react with Tilesafe. If silicone sealant is to be used, for example on bath surrounds, ensure it does not come into direct contact with the Tilesafe.
• In the unlikely event of the Tilesafe Membrane being damaged, it is easily repaired by applying a piece of reinforcing tape over the damaged area, ensuring a minimum overlap of 50 mm.

Note

Tilesafe is compatible with DEVI electrical under-floor heating.

All the information on the installation pages should be read in conjunction with the standard literature and product information sheets.

Detailing and application should also be in accordance with design drawings and site specification.

The Tilesafe system is patented in the UK.

Product Overview

Tilesafe is a heavy duty self-adhesive membrane, consisting of a thick rubber modified bitumen waterproof layer incorporating a woven glass fibre mesh on one face.

The Tilesafe system has been developed to provide waterproofing beneath ceramic tiles in bath-shower rooms and other wet rooms.

This flexible membrane can be fixed to ply, masonry, concrete or plasterboard surfaces and is compatible with all ceramic adhesives. Vastly reducing labour costs with its swift installation time of just a few hours, this superior membrane is provided in kit form with everything you need to cover an area of 5m2 or 10m2.

Guaranteed for the lifetime of the tiles, you can be confident of creating a watertight area every time.

Ancillary Products

There is a range of ancillary products for use with Tilesafe which include:

• Tilesafe Primer – an acrylic emulsion primer for coating all surfaces prior to the application of Tilesafe Reinforcing Tape and Tilesafe Membrane.
• Tilesafe Reinforcing Tape – a tape for reinforcing all wall junctions, butt joints and other detail work in the membrane.
• Tilesafe Jointing Compound – a high quality, gun applied, butyl rubber-based sealant for use at all butt joints in the membrane, pipe entries, wall to wall and wall to floor interfaces.
• Tilesafe Putty – a non-setting, self supporting mastic for filling small gaps or voids around tile entries, etc. prior to application.

Safety

Tilesafe Jointing Compound is flammable and should be used in well-ventilated areas away from sources of ignition. The product can affect sensitive skins. Gloves or barrier cream should always be used by operatives and hands thoroughly washed at the end of each working period. Do not allow the product to enter watercourses. Full health and safety instructions are contained on the material safety data sheets, and these must be referred to before use.

Storage

Tilesafe Membrane, and its ancillary products, should be stored in original cartons. The products should be kept upright, protected from frost, and out of direct sunlight, i.e. below 35°C. Cartons should not be over-stacked.

Care should be taken to ensure the temperature is at least 10°C. Conditioning of the membrane in a warm area, prior to use, will enhance its adhesion properties during application.
