Consumption

Consumption

Powder consumption and coverage depends on the surface profile and roughness of the substrate, size and reverse profile of the tiles and the placing technique (simple placing "floating" or back to back “buttering-floating”).
As a guide:
For 1 mm thickness over 1 m2 area approximately 1.4 kg of powder is required.
For small sized tiles (side ≤30 cm), use small squared notch size trowel (4-6 mm) and progressively increas for medium tiles (side ≤45 cm, trowel 6-8 mm) or large tiles (side ≤60 cm, trowel 8-10 mm).
This figure is theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

Application steps

EQUIPMENT

Select the most appropriate equipment required for the project:

Substrate preparation equipment

  • Grinding equipment
  • Abrading equipment
  • Power washing equipment
  • Sandblasting equipment

Mixing equipment

  • Low speed electric single or double paddle mixer (300–400 rpm) with a spiral mixing paddle.

Application equipment

  • Notched trowel
 

MIXING

  • Mix a bag with the necessary, above mentioned, amount of water, using an electric blender with a suitable mixing spiral at low speed, in a clean bucket, and up to obtain a smooth paste free of lumps.
  • Use a blender at 500 rpm maximum; do not mix at faster rate because of mechanical strength decay of the cured product.
  • After blending, leave the product curing for 5 minutes in the mixing container and then briefly stir the mix prior to application.
  • Always start with minimum recommended quantity of water (water/powder ratio), only if required, gradually add water to desired consistency. Do not exceed maximum allowed limit of water per bag weight.
  • The obtained mix results should be very creamy, easily spreadable and thixotropic.
  • Do not mix more material than can be used within 60 minutes.
 

APPLICATION

SikaCeram®-118 BH is applied using notched trowel. The amount of product should be enough to ensure complete wetting of the tiles rear. Tiling has to be carried out on fresh glue, exerting an adequate pressure to ensure contact with the adhesive, and thus the perfect bonding. In case a surface film is formed on the adhesive, it is necessary to wipe the trowel on the adhesive layer previously applied. Avoid wetting already applied adhesive with water, as it may negatively affect its properties.
Note: For tiles > 900 cm2 (30 x 30 cm), the double spreading ("buttering") technique is always recommended.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
