Versatile C1 Tile Adhesive for Indoor Ceramic and Porcelain

The coverage depends on tile size, substrate flatness, and trowel notch depth. For thin-bed application, about three to five kilograms per square meter. So one twenty-kilogram bag covers about four to six square meters. If the substrate is uneven or a thicker trowel is used, consumption will be higher. Calculate based on actual area and allow a small margin for waste.

Generally, mix powder and water at about four to one that is, twenty kilograms of powder with about five liters of clean water. Check the product instructions for exact ratio. Never add cement, sand, or other materials, as this will disrupt the formula and cause reduced bonding, cracking, and hollowing. Just mix with clean water.

Use the mixed adhesive within two hours. In hot or dry weather, it dries faster. Never add water to dried or partially set adhesive bonding strength will be greatly reduced, and tiles may fall off. Mix only what you can use in time do not mix too much at once.

Generally, grouting or epoxy grouting can be done one to two days after tiling. It depends on weather, temperature, and tile size. In humid or cold conditions, extend to three to seven days until the tile adhesive fully hardens and moisture evaporates. Otherwise, the grout may discolor or peel off due to moisture.

Yes, but with caution. Underfloor heating causes thermal expansion and contraction, requiring some flexibility from the adhesive. C1 is a standard type it can be used if temperature changes are moderate and the substrate is stable. However, if the heating system has large temperature swings or heats up quickly, choose C2 tile adhesive with better flexibility to prevent cracking and hollowing. Make sure the heating is turned off and the floor has cooled to room temperature before tiling.
