Consumption

Consumption

As tile adhesive:

Consumption is dependent on the surface profile and roughness of the substrate, as well as on the application technique (single spreading/floating method or double spreading/buttering method).

As a guide, the approximate consumption is given in the following table:

Size of tiles

Notched trowel size

Consumption

Small

6 mm

~2 kg/m2

Medium

8 mm

~2.5 kg/m2

Large10 mm~3 kg/m2

As tile grout:

Consumption is dependent on the surface profile and roughness of the substrate as well as on the size of the tiles and the joints between them. As a general guide, the approximate consumption can be calculated by volume, where ~1,7 kg/m2/mm of material is required.

Consumption of tile grout can be also calculated through the following formula:

((L1+ L2) x W x T x D ) / (L1 x L2) , where:

  • L1 = Length of tile (mm) - First side
  • L2 = Length of tile (mm) - Second side
  • W = Joint width (mm)
  • T = Tile thickness (mm)
  • D = Fresh mortar density of tile grout (kg/l)

Note: Final result will be in kg/m2 .

Note: All figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.
Application steps

MIXING

SikaCeram®-801 RTG is a reactive product. This means that it sets through a chemical reaction between the two components A and B. It is therefore crucial to ensure that these components are thoroughly mixed with the correct mixing ratio.

Thouroughly mix the base (Comp. A). After mixing the base, pour all the hardener (Comp. B) into the container of the base (Comp. A) and mix with an electric low speed drill (~350 rpm.) mixer equipped with a suitable mixing spiral. Mix thoroughly for approx. 3 minutes, until the material is fully homogeneous and lump free. The finished mix has a very creamy consistency, is uniformly coloured and it is easy to apply and spread.

APPLICATION

Tile grout:

SikaCeram®-801 RTG is applied using a rubber blade or trowel using cross-hatch techniques, taking care to ensure the joints are filled uniformly across the whole width and along their full length.

Using the same blade/trowel in a vertical position, remove the excess from the surface of the tiles.

When the product starts to set, it is possible to begin the cleaning step. Squeeze a sponge soaked in water over the grouted surface and emulsify the product by performing circular movements, taking care not to damage the joint.

Frequently rinse the sponge with fresh water during the cleaning operation. Be careful not to wash out the grout.

After cleaning, carefully check if the tiles are completely free from any traces of the grout. Once hardened, the product can only be mechanically removed.

Tile adhesive:

SikaCeram®-801 RTG is applied using a notched trowel. Apply sufficient product to ensure complete ‘wetting’ of the backs of the tiles. Tiling must be carried out on freshly applied adhesive, exerting adequate pressure to ensure complete and uniform contact with the adhesive and thus optimum bond. If a film is seen to form on the surface, the adhesive has been left for too long; should this happen, then immediately remove the adhesive layer with the trowel, discard this material and apply a fresh layer of SikaCeram®-801 RTG adhesive. Avoid application in direct sunlight and/or strong wind / draughts. To lay any tiles larger than 900 cm2 (e.g. 30×30 cm), the double-layer ‘buttering’ technique is always recommended.

Protect from adverse weather conditions, such as extremely high or low (freezing) temperatures, rain, direct exposure to sun, for at least 12–24 hours from application.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water and/or Sika's Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
