Coverage
Depending on the nature and evenness of the surface and method of application, approximately 6m2 per 20kg bag when applied using a 6mm notched trowel. This coverage is reduced when Weber.set Mosaic fix is used as an adhesive and grout in one application.
Storage and shelf life
When stored, unopened in a dry place at temperatures above 50C, shelf life is 6 to 9 months from date of manufacture.
Surface Preparation
The following minimum curing periods should be observed before tiling commences :
- New concrete floors : 28 days
- New screeds : 28 days
Ensure that all surfaces are clean, dry, sound and free from dust, grease or any contamination that could impair bonding. Make good any unsound areas and remove flaky or peeling layers before tiling.
Organic growth must be removed and the spores killed using household bleach. PVA paint and gypsum plaster must be chipped to expose 80% of the substrate. Enamel paint and bitumen should be scraped and chipped to expose 80% of the substrate. Do not use a solvent or heat to remove bitumen from the surface. Existing ceramic tiles must be thoroughly cleaned using undiluted Tylon Tile Cleaner. Rinse using clean water.
Smooth-, off form-, shutter- or power floated cement surfaces should be acid washed to remove laitance. Rinse well with cold water.
Highly absorbent surfaces must be primed using a mix of 2 volumes of Tylon Plaskey and 1 volume Tylon Key-it. Apply to a thickness of approximately 2mm using a blockbrush. Leave to dry for 24 hours.
General
- Tiles should be installed providing for adequate movement joints. Movement and expansion joints to be provided for at approximately 3 metre centres externally or at 4 metre centres internally, in both directions or as per the engineer’s specifications.
- All expansion and movement joints in the substrate must extend through the adhesive bed and tiles.
- Tiles must have full contact with the adhesive - leave no voids.
- Use only dry tiles - do not soak tiles.
Mixing
- Combine a 20kg bag of Tylon Mosaic Fix with 6 to 6.5 litres of clean water and mix to a creamy paste. I
- f less than the complete bag is used, the mix proportions are 2 parts by volume of powder to 1 part by volume of water.
- In wet or permanently wet conditions, replace the water in the mix with Tylon Bond-it.
- Allow the mixture to mature for 5 minutes and re-mix thoroughly. Do not add more water.
When laying glass-, marble-, ceramic- or porcelain mosaic tiles, replace the water normally used in the mix with Tylon Bond-it.
Do not add too much water or attempt to extend the working time by adding more water as this will cause the adhesive to be weak with a tendency to crumble.
Do not mix more adhesive than can be applied within 90 minutes.
Application
Spread adhesive using a 10mm notched trowel when using Weber.set Mosaic Fix as an adhesive and grout. Do not spread more adhesive than can be laid in 10 minutes.
Use a 6mm notched trowel when using Weber.set Mosaic Fix as a mosaic adhesive only. All expansion- and movement joints are to extend through the adhesive bed and tiling.
Bed the mosaics firmly into the wet adhesive. Paper covering on mosaics can be removed 1 hour after application.
Occasionally lift a tile to check that full contact is being made between the tiles and the adhesive.
Clean excess adhesive off the surface once mosaics are firmly set using a damp sponge. Once the adhesive has hardened, only mechanical removal is possible.
The joints must be allowed to dry for 24 hours before polishing with a clean, dry cloth.
Grouting
Ensure that the joints are free from tile adhesive and any other foreign matter.
Allow 6 hours before grouting with Tylon Tile Grout. Allow 48 hours for sealed or non-porous surfaces.
In wet or permanently wet conditions, replace the water in the mix with Tylon Bond-it.
