Preparation & Application

Surface Preparation

The following minimum curing periods should be observed before tiling commences :

  • New concrete floors: 28 days
  • New screeds: 28 days
  • New brick walls: 28 days
  • New cement plaster: 28 days

The walls or floors to be tiled must be wood-floated and not steeltrowelled or power-floated. 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 tiles must be thoroughly cleaned using a suitable cleaner. Rinse using clean water. Smooth-, off form-, shutter- or powerfloated cement surfaces should be acid washed to remove laitance. Rinse well with water.

Highly absorbent surfaces must be primed using a mix of 2 volumes of weber.prim Plaskey WB250 and 1 volume weber.ad Key-it WB117. Apply to a thickness of approximately 2 mm using a blockbrush. Leave to dry for 24 hours.

Mixing

  • Combine a 20 kg bag of weber.set Mosaic-Fix with 6.5 litres of clean water and mix to a creamy paste.
  • In wet or permanently wet conditions, replace the water in the mix with weber.ad Bond-it WB183.
  • 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 weber.ad Bond-it WB183.
  • 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 8 hours.

Application

Spread adhesive using a 10 mm notched trowel when using weber.set Mosaic-Fix as an adhesive and grout. Do not spread more adhesive than tiles that can be laid in 20 minutes. Use a 6 mm 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.

Coverage

Depending on the nature and evenness of the surface and method of application, approximately 6 m2 per 20 kg bag when applied using a 6 mm notched trowel (wall tiling) and 4 m2 per 20 kg bag when applied using a 10 mm notched trowel (floor tiling) ie: based on a level/ even floor. This coverage is reduced when weber.set Mosaic-Fix is used as an adhesive and grout in one application.

Grouting

If weber.set Mosaic-Fix is not used as a grout, please ensure that the joints are free from tile adhesive and any other foreign matter. Allow 24 hours before grouting with weber.grout Tile Grout WB33. Allow 48 hours for sealed or non-porous surfaces. In wet or permanently wet conditions, replace the water in the mix with weber.ad Bond-it WB183.

Packaging, Health & Safety

General

  • Tiles should be installed providing for adequate movement joints. Movement and expansion joints to be provided for at approximately 3 m centres externally or at 4 m 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.

Packaging

weber.set Mosaic-Fix is supplied in 20 kg bags.
