Uses
RAK TILE FIX WP is used for permanent fixing of ceramic tiles for internal applications.
It may be suitable for use in : Kitchens, Bathrooms and Regular Rooms
Features
Surface Preparation
All surfaces should be sound, clean & uncontaminated. This preparation should leave an exposed concrete surface free from dust, loose particles, deletrious matter, oil, grease, chemical films & other contaminant.
All loose particles of mortar, paint, etc. must be physically removed.
Concrete or blockwork: allowed to cure su ciently so that all shrinkage movements take place before fixing tiles.
Gypsum supports: treat with 304-5. Should not have a percentage of humidity more than 10%.
The surface of substrates must be moistened slightly with clean water to reduce the absorption of water from the mortar. Do not moistened the tiles.
Mixing
Place 5.0 – 5.25 liters of cold, potable water (or Bond SBR as needed) in the mixing bucket and add slowly 25 kg bag of RAK TILE FIX WP under continuous mixing till a uniform lump free consistency mix is achieved. For mixing process, a slow speed drill (200- 300rpm) fitted with a suitable paddle is recommended.
Allow the obtained mix to stand for about 5 minutes and then remix before application.
Application
Spread RAK TILE FIX WP on the substrate to a uniform thickness using a toothed spatula, the first pass with its straight edge and the second pass immediately after, to the desired thickness of RAK TILE FIX WP using the toothed part.
Place the tiles onto the adhesive bed. Apply su cient pressure on the tile during fixing it with slight twisting movement in order to ensure good contact with the adhesive.
In case of large size tiles, it is necessary to spread the adhesive also to the backside of the tile and then place the tiles into the adhesive bed.
Apply enough material that can be tiled during the adhesive’s open wet time. Spreading large areas may result in drying the adhesive before tiles can be fixed causing poor adhesion.
Finishing
Remove excess adhesive with a damp cloth before it dries. Joints grouting between tiles may be commenced after 10 hours of tiling for walls and 24 hours for floors.
Cleaning
Tools and equipment should be cleaned with water immediately after use. Hardened materials should be mechanically removed.
Recommendations
- To achieve improve adhesion strength, it is recommended to replace water with Bond SBR.
- The grey type presents higher mechanical resistances. It is therefore advisable to use to fix tiles on floor
- Sti ened mortar must neither be diluted with water nor with fresh mortar
- Do not use RAK TILE FIX WP on metal or non-absorbing surfaces.
- Do not apply RAK TILE FIX WP in rainy weather, high winds and sand storms
- Do not apply under direct sun • Keep equipment cool and use cold water
- Porosity of tiles and substrates has significant e ect on adhesive strength of tile
Consumption
Approx. 4 to 4.5 kg RAK TILE FIX WP per m² using notched trowel on smooth surface. Consumption will vary according to type of tiles and support condition.
Storage
Store in dry covered place in the original closed bags and shelf life is 12 months if stored as recommended.
Health & Safety
RAK TILE FIX WP can be harmful to skin as it contains cement powders which may releases alkalis when mixed with water. During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary. In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly. If ingested, obtain medical attention immediately. Do not induce vomiting.
