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 steel-trowelled 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.

Problem Surfaces:

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 well with cold water. Smooth-, off-form-, shutter- or power floated cement surfaces should be acid washed to remove laitance.

Rinse well with cold water. Once the surface preparation has been completed on the above problem surfaces, the area must be primed using a mix of 2 volumes of Weber Plaskey and 1 volume of Weber Key-it.

Apply to a thickness of approximately 2 mm using a block-brush. Leave to dry for 24 hours.

Mixing

  • Combine a 20 kg bag of Weber Renovate Adhesive Grey with 5 litres of clean water and mix to a creamy paste.
  • Though Weber renovate adhesive has waterproofing properties; if the application is done where excessive wet conditions persist: i.e. walkways where puddles occur frequently; replace all water with Weber Bond-it.
  • Allow the mixture to mature for 5 minutes and re-mix thoroughly. Consistency can be adjusted by adding more water.
  • 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 1 hour.

Application

Spread adhesive using a notched trowel to a minimum bedded thickness of 3 mm on walls and 6 mm on floors. Heavily lugged, grooved or dovetailed tiles must be buttered to fill any voids with adhesive before placing into wet adhesive. Press tiles firmly into wet adhesive with a twisting action. Use a rubber mallet to bed large or heavy tiles.

Occasionally lift a tile to check that full contact is being made between the tile and the adhesive. Do not butt joint tiles. Clean excess adhesive off the surface once tiles are firmly set using a damp sponge. Once the adhesive has hardened, only mechanical removal is possible. Minimum grouting joints for walls is 2 mm and 3 mm for floors. Adhesive must be allowed to dry for 6 hours before grouting commences.

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 when using a 10 mm notched trowel (floor tiling) ie: based on a level/even floor.

Grouting

Ensure that the joints are free from tile adhesive and any other foreign matter. Allow 6 hours before grouting with Weber Tile Grout . Allow 48 hours for sealed or non-porous surfaces. In wet or permanently wet conditions, replace the water in the mix with Weber Bond-it.

Packaging, Health & Safety

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.

Packaging

Weber Renovate Adhesive Grey is supplied in 20 kg bags.
