Usage
SikaCeram®-30 is developed for swimming pools and may be used in wet process applications including abattoirs, shower rooms, institutional kitchens, bathrooms, etc.Used in conjunction with SikaCeram® RSG 705, the system is suitable for use where chemical resistance or a high standard of hygienic quality is essential.
For extreme conditions such as vibration or temperature extremes etc. SikaCeram®-30 can be mixed with suitable latex based additive, instead of water. When mixed with SikaCeram® A 200, SikaCeram®-30 may be used to tile directly onto glazed tile surfaces and is recommended for non-porous or high density glass mosaics and moisture tolerant natural stone. Please consult Sika's Technical Service Department for advice. SikaCeram®-30 is suitable to be applied on following substrates:
- Concrete

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 solid bed application:
For 1 mm thickness over 1 m2 area approximately 1.5 kg of powder is required.
This figure is theoretical and does 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. Above consumption indications refer to the installation of slightly profiled, non-vitrified or vitrified tiles on flat substrate e.g. render or cement screed.
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).
Yield
A 20 kg bag mixed with 3.6 - 4.0 L of water yields approximately 13.1 - 13.3 L of mixed adhesive.
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 (recommended 300–400 rpm) with a spiral mixing paddle.
Application equipment:
- Notched trowel, various sizes
SUBSTRATE QUALITY
- Cementitious substrates must be sufficiently cured and dried.
- All substrates must be structurally sound, able to support the weight of the new tiling and provide a firm and securely fixed background.
- The substrate must be flat, tight and free from easily removable parts, non-deformable and correctly aged.
- Substrates must be clean, dry, free of any loose or friable particles, contaminants such as dust, dirt, oil, wax polish, grease, cement laitance or efflorescence.
- The substrate must be plumb and flush in accordance with BS 5385. Plaster substrates must be approved by the plaster manufacturer for fixing ceramic tiles and must be suitable for the intended area of use.
SUBSTRATE PREPARATION
- Use adequate mechanical preparation techniques to remove from the substrate, all traces of any materials that could reduce the product's adhesion to the substrate.
- Smooth surfaces must be roughened lightly to improve adhesion.
- To confirm adequate surface preparation and adhesion, carry out a small trial before full application.
- For larger and thicker areas of substrate re-profiling, use suitable mortars from the Sika MonoTop® or SikaEmaco® range. Level concrete floors with SikaScreed® or SikaLevel® range.
- For any repairs of the substrate materials of SikaEmaco®, SikaRep® or Sika MonoTop® range should be used, applied at least 24 hours before laying the ceramic tiles.
- Identify cracks in the substrate and seal appropriately with Sikadur® epoxy resins.
- For applications in hot climates / environments, or on absorbent substrates, thoroughly pre-dampen (saturate) the substrate before product application.
- Avoid any ponding / standing water on the substrate.
- Surface must not be damp to touch.
- For tiling in constantly damp or wet rooms, a suitable Sika® waterproofing product / systems must be applied to the substrate before tiling.
- Prime very absorbent cement-based substrates, aerated concrete, renders, plaster boards or gypsum fibre boards with suitable primer. Contact Sika® Technical Service Department for recommendation.
MIXING
Mix a bag with the necessary, above mentioned, amount of clean water, using an electric blender with a suitable mixing spiral at low speed, in a clean bucket, 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.
Allow a maturing time (slake time) of approx. 5 minutes for SikaCeram®-30 in the mixing container, then remix briefly 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 pot life.
Larger quantities may be mixed with forced action mixer.
APPLICATION
SikaCeram®-30 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 adhesive off and re-apply. 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.
Adhesive application:
- Apply a thin scratch coat to the substrate with the smooth edge of the trowel.
- Comb mortar onto the fresh scratch coat with a notched trowel.
- Apply sufficient adhesive to the prepared fixing surfaces with the notched trowel to the required bed thickness, in one direction.
- Place the tiles in the adhesive bed with a twist and slide motion and adjust to correct position.
- Adjust the tiles if required.
- Clean off surplus adhesive from tile face and between tile joints before the adhesive has dried.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
