Store properly in dry conditions, in undamaged and unopened, original sealed packaging.

5.75–6.25 L of water per 25 kg bag

~20 minutes at 25 °C

~24 hours at 25 °C

~15 minutes at 25 °C

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, in kilogram of powder per m² on flat surfaces:

The consumption above may only serve as a guide. It is highly recommended to carry-out trials on site to determine the actual coverage.

Pour clean water into a mixing container. Then, slowly add SikaCeram®-98 whille mixing. Mix continuously in a circular motion using a low-speed mechanical mixer until a lump-free, creamy consistency and uniform paste is achieved.

Allow the mix to stand for 5 minutes and re-mix prior to use.

SikaCeram®-98 is spread onto the substrate using a proper and suitable notched trowel. The choice of trowel should be governed by the size of the tiles, depth of knobs, grooves or ridges on the back of the tiles and the evenness of the substrate.

Use the flat side of the notched trowel to spread the mix onto the receiving surface at approximately 1 m² at a time. Then, use the notched side of the trowel to apply the required amount of the mix in one direction.

Press the tile in a perpendicular motion and tapped into position to ensure positive contact with the adhesive and adjust within 30 minutes.

For tile with grooves or ridges, it is necessary to skim a layer of adhesive / butter coat the back of the tiles. This is to ensure good adhesion and adequate coverage between the adhesive and tile.

Ensure that the adhesive is wet when the tiles are laid. Do not allow the adhesive to skin-over prior to tilling. Should skinning occur, break the skin by re-trowelling the adhesive in the opposite direction.

Do not spread more than 1 m² at any one time. Fix the tiles within 15 minutes of applying the adhesive and check the contact by occasionally lifting tiles. Ensure there are no voids under the tiles and the edges between the tiles are even (lippage) with consistent tile joint width.

Grouting

Tile joint grouting should preferably be carried out at least 24 hours after completion of tiling or until the adhesive has set and dry sufficiently.

Setting may be delayed on dense or impervious surface.

Clean all tools and application equipments with clean water immediately after use. Hardened or cured material can only be removed mechanically.
