To calculate tile adhesive coverage for your project you can use the Sika Tile Adhesive Calculator found here.
Yes. Sikafloor®‑200 Level is designed to build slopes in wet rooms and showers, providing a smooth, stable base that ensures proper drainage and reliable tile adhesion.
To waterproof a wet room using the Sikalastic®‑260 Stop Aqua kit, start with a clean, dry substrate and apply a suitable primer, like Sikafloor®-03 Primer. Apply the first layer of Sikalastic®‑260 Stop Aqua on the surface area you wish to waterproof. Take Sika® SealTape and apply it carefully to corners, wall and floor junctions and drain areas. Then apply the second coat of Sikalastic®‑260 Stop Aqua, once this is dry the area is waterproof!
Use Sika’s complete wet room system kit, Sikalastic®‑260 Stop Aqua, to create a robust waterproof finish ready for the application of tiles.
For large format tiles, use SikaCeram®-250 StarFix Rapid, a high-performance fast setting tile adhesive, to ensure strong adhesion.
To apply tile grout, first ensure that the tiles are fully set. Mix the grout according to the instructions on the Product Data Sheet, then use a rubber grout float to press it firmly into the tile joints at a 45° angle. Remove excess grout from the tile surface with the float, then wipe tiles with a damp sponge to clean residue. Once the grout has cured use a sanitary silicone sealant to seal any corner joints.
SikaSeal®-175 is a sanitary silicone sealant for sealing shower trays, bathtubs and sinks as well as connection joints in bathrooms. It has excellent long-term resistance to mould growth ensuring your bathroom remains clean, healthy and mould free.
To waterproof a shower area, start with a clean, dry substrate and apply a suitable primer, like Sikafloor®-03 Primer. Apply the first layer of Sikalastic®‑260 Stop Aqua, a liquid waterproofing membrane, on the surface area you wish to waterproof. Take Sika® SealTape and apply it carefully to corners, wall and floor junctions and drain areas. Then apply the second coat of Sikalastic®‑260 Stop Aqua – once dry, the surface is waterproof!

Tile adhesive should be applied to a clean, dry and stable substrate using a notched trowel. After preparing the surface and ensuring any required priming or waterproofing is complete, spread the adhesive evenly across the area, holding the trowel at a consistent angle to create uniform ridges. Press each tile firmly into the adhesive, adjusting as required to achieve the correct alignment. Always follow the open time and working time stated on the Product Data Sheet and take care to avoid applying more adhesive than can be tiled over within that timeframe.

A 20kg bag of tile adhesive typically covers an area of around 3 to 5 m². Uneven or porous surfaces require more adhesive to achieve a level and secure bond. A well-prepared, flat surface allows for more efficient coverage. Always check the Product Data Sheet for the most accurate coverage rates and recommended application methods for your project.
The recommended tile adhesives for bathroom tiling are cement-based polymer modified tile adhesives that are flexible, water-resistant and classified at minimum as C2TE S1.
Sika offers SikaCeram®-204 Medium White, a cement-based tile adhesive with improved adhesion for ceramic tiles, or SikaCeram®-204 Rapid, a rapid setting tile adhesive.
Sika tiling products are compatible with common substrates, including concrete, cementitious substrates, existing ceramic and stone tiles, gypsum substrates and wooden OSB and chipboard substrates. Refer to the Product Data Sheet for each product for the full list of compatible substrates before application.
Yes. Sika’s range includes tile adhesives, grouts and waterproofing membranes that are designed to be compatible with both walls and floors.
A full tiling project typically requires a primer, levelling compound, waterproofing membrane, tile adhesive, tile grout and a sanitary silicone sealant for joints. Sika offers a fully compatible system designed to deliver durable, long-lasting results across a variety of substrates and tile types.
Sika supports sustainable concrete production by offering admixtures and technologies that help reduce material use, improve energy efficiency and enhance overall concrete performance. Our solutions are designed to optimise production processes, extend durability and support the use of alternative aggregates. With Sika, you can improve the environmental footprint of your concrete while maintaining consistent quality and reliability. Read more about how to make concrete more sustainable here.
Sika concrete admixtures enhance 3D concrete printing by improving flow, buildability and early strength development. These tailored admixtures help achieve consistent extrusion, faster layer stacking and precise shaping, ensuring reliable printing performance.
