How to Apply Sika 188

1. Surface Preparation: Ensure surfaces are clean, dry, and free from contaminants. For porous surfaces, use a primer to enhance adhesion and prevent premature drying of the adhesive.
2. Mixing: Combine Sika 188 with water at a ratio of approximately 4.5 to 5 liters of water per 25 kg bag. Use a mechanical mixer to achieve a smooth, lump-free paste. Allow the mixture to rest for 5 minutes, then remix.
3. Application: Apply the adhesive with a notched trowel, adjusting the notch size based on tile size and substrate. Work in manageable sections to prevent the adhesive from drying out. Ensure even coverage and press tiles firmly into the adhesive bed.
4. Tile Installation: Place tiles into the adhesive bed with a firm press, ensuring full contact. Use a rubber mallet to seat tiles properly and check alignment frequently.
5. Curing and Grouting: Allow the adhesive to set for at least 24 hours before grouting. The curing time may vary depending on environmental conditions.
