Description
SikaCeram®-88 is a one-pack premixed cementitious tile adhesive containing, cement, polymers, quartz minerals and additives, for bonding ceramic tiles and mosaics to floors and walls.
Characteristics / Advantages
▪ Easy to use with excellent workability and thixotropic consistency.
▪ Very good adhesion to most common substrates (concrete, cementitious mortar, stone, bricks, etc.).
▪ Can be used with SikaLatex®-88 or SikaLatex®-118 to increase performance of the adhesive.

Application Information
▪ Mixing Ratio: 5.5–6.0 L of water per 25 kg bag
▪ Fresh Mortar Density: ~1.79 kg/l at +25 °C
▪ Consumption:
This depends on the level, profile and surface roughness of the substrate, the size of the tiles and the technique of placing (simple placing or "back"- buttering).
As a guide, per m² on flat surface:
- Mosaics and small tiles 2.0–4.5 kg/m²
- Normal size tiles (20 cm x 20 cm) 4.5–9.0 kg/m²
* This may only serve as a guideline. It is highly recommended to carry-out trial on site to determine the actual consumption per m².
▪ Layer Thickness: 3 mm min. / 10 mm max.
▪ Ambient Air Temperature: +5 °C min. / +40 °C max.
▪ Substrate Temperature: +5 °C min. / +40 °C max.
▪ Open Time: Open time is ~20 minutes under normal temperature and humidity conditions. In unfavourable conditions, the open time may be shorter.
▪ Adjustability Time: Once the tiles are placed into the mortar, they can be adjusted within ~20 minutes (at +20 °C).
▪ Applied Product Ready for Use: At +25 °C
- Before jointing works Min. 24 hours

- Before opening to full traffic Min. 7 days
Uses
SikaCeram®-88, is used for bonding ceramic tiles in continuous thin layers, up to 10 mm thick. Due to its excellent adhesion strength, it is used to replace the traditional method of bonding tiles (using cement and sand).
SikaCeram®-88 is suitable to bond the following types of tiles:
▪ Ceramic, homogeneous and mosaic tiles.
▪ Porcelain tiles (SikaCeram®-88 shall be mixed with SikaLatex®-88 or SikaLatex®-118).
SikaCeram®-88 can be used on walls and floors internally, on these substrates:
▪ Concrete and mortar.
▪ Bricks.
Application
▪ SikaCeram®-88 is applied using a notched trowel onto the substrate.
▪ Choose the size of trowel that will give the right thickness on the back of the tile.
▪ After the surfaces of the substrate has been prepared, apply SikaCeram®-88 onto the substrate using a notched trowel.
▪ SikaCeram®-88 should be applied onto the substrate at a rate of 1 m² per installation.
▪ Applying at rates greater than this can result in skinning of adhesive before the tiles are laid.
▪ Once the adhesive is applied onto the substrate, ensure that skinning has not occured prior to setting the tiles.
▪ If a surface film has developed, make a pass over the adhesive using a notched trowel.
▪ Rework the adhesive before setting the tiles within the open time.
▪ When setting the tiles into the adhesive, use the Tarver Method; press, slide perpendicular and slide return.
▪ This method will ensure that any air entrapped between the beads comes out easily at the ends.
▪ For tiles with lugs, grooves or uneven backing, it is required to backbutter the tile with adhesive before setting them down.
▪ The final bed thickness of SikaCeram®-88 should be at least 4 mm for wall and 8 mm for floor.
▪ Once the tiling works are completed, do not disturb the tiles for at least 6–8 hours.
▪ As a guide:
- SikaCeram®-88 is used for fixing absorbent / ceramic tiles up to a maximum size of 3 600 cm² (e.g. 60 cm x 60 cm) for indoor floors, up to 1 800 cm² (e.g. 30 cm x 60 cm) for indoor walls.
Important Considerations
When use in conjuction with SikaLatex®-88 / SikaLatex®-118, please ensure that all ratio of SikaLatex®- 88 / SikaLatex®-118 to SikaCeram®-88 are consistent.
Please refer to respective data sheet for more details.
▪ Protect freshly applied material from extreme conditions, rain, etc.
▪ Do not attempt to dampen down the adhesive on the floor/wall to extend the open time as this may affect the bond performance.
