AQUAFIX is a brilliant white ready mixed adhesive paste, for use as an All-purpose thin-bed waterproof ceramic wall tile adhesive and joint filling grout, which conforms to BS 5980 Type 2 Class AA (BS EN 12004 Type D, Class 2T). Suitable for fixing all types of ceramic wall tiles, including mosaics, porcelain and vitrified tiles in internal locations such as bathrooms, kitchens and shower areas where the tiled surface is subject to frequent wetting, but not total water immersion. AQUAFIX can be applied to gypsum plaster, cement fibreboard, existing tiles, cement render, concrete blockwork, timber panels and plywood composite boards. AQUAFIX is recommended for use in areas such as multi shower changing rooms, steam rooms, power showers, worktops and any tiled wall surface, which is subject to persistent humidity or frequent wetting. The dual-purpose application properties of AQUAFIX make it particularly suited to small area DIY applications and localised repairs.
All surfaces must be clean, firm and free of dust, dirt, oil, grease and lose flaking coatings. Gypsum finishing plaster should be at least 4 to 6 weeks old, thoroughly dry and wiped clean of dust, efflorescence and loose flaking material. Highly polished (shiny) plaster surfaces should be roughened with a stiff brush, removing all loose fines. All plaster and porous masonry surfaces should be primed with TILERS PRIMER diluted as 1 part to 3 parts with water and allowed to dry. All wood-based surfaces, (plywood and composite panel-boards) should be dry, sealed on all exposed faces and edges and then primed using TILERS PRIMER diluted as 1 to 3 parts water. Timber boarding should be waterproof rated, 15mm thick and be screw fixed at 150mm centres to provide a dimensionally stable background as described in BS 5385. Infrequently wet areas where AQUAFIX is used it is not recommended that wall panels be constructed from plasterboard or any composite material, which does not have some degree of water resistance. All boards must be level, showing no edge protrusions and be fixed in place with a 0.5 to 1mm gap to avoid expansion stresses between the boards and around the wall corners. Remove areas of unsound (emulsion-based) paint from walls and when tiling over existing tiles ensure they are securely fixed. Thoroughly clean and dry tiled, or non-porous surfaces and slightly score out joints to provide a key.
AQUAFIX is intended for application by a notched trowel (5mm x 5mm notch at 10 mm centres) to give a ribbed bed on the wall surface, into which the tiles are firmly bedded with a twist and slide action to ensure complete contact, without any voids or gaps remaining beneath the tiles. The position of the tiles can be adjusted up to 10 minutes after initial fixing. Open time of the exposed adhesive bed is approximately 20 minutes, depending on surface porosity and site conditions, however, in warm rooms, this period may be reduced – check the adhesive remains “tacky to touch” as fixing proceeds. Do not trowel out an area of adhesive greater than can be tiled over within a 10 minute period (about 1 square metre). The final adhesive bed depth should be in the range of 2 to 3mm and grout joints should be at least 2mm unless self-spacing tiles are used. Ensure all adhesive residues remaining on the tile face are wiped clean with a moist cloth as fixing proceeds. AQUAFIX should not be applied onto walls affected by penetrating damp, or when the temperature is below 5’C. When fixing porcelain tiles the drying time of the adhesive will be significantly extended therefore grouting should be delayed until the adhesive is fully dry, additionally, any porcelain tiles of size 300mm x 300mm or greater should ideally be fixed using a cement-based adhesive. Additionally, all types of large format ceramic tile, i.e. those with dimensions of 300mm x 400mm or more, will also significantly prolong the drying time of this adhesive and a cement-based alternative is strongly recommended in such circumstances.
Grouting may proceed as soon as the tile bed is sufficiently firm, which depending upon site conditions can be from 24 hours after fixing on porous surfaces such as plaster or up to 7 days where tiles have been fixed to an impermeable surface such as existing tiles or waterproof boards. When grouting with AQUAFIX, thoroughly stir the paste to a creamy consistency and use either a sponge or rubber squeegee to work AQUAFIX thoroughly and completely into all the joint spaces. Joint widths of up to 6mm wide and 10mm deep can be grouted using AQUAFIX. Wipe off excess grout with a damp cloth and allow up to 14 days for both the adhesive and grout to fully dry out before subjecting the tiled area to contact with water.
Coverage & Classification:
Depends on the surface texture and porosity, however on a typical smooth plastered wall using 150mm x 150mm x 6mm tiles with a 2mm joint width AQUAFIX will “fix and grout” at a rate of approximately 2.5 kg per square metre.
Storage & Packaging:
AQUAFIX is supplied in 15 kg; 7.5 kg; (3.75 kg x 4); (1.5 kg x 12) and (0.75 kg x 12) buckets and has a storage life of not less than 12 months if kept in dry, un-opened conditions. Consult the AQUAFIX material safety data sheet for advice on handling and safety procedures
