Application Techniques

a. Surface Preparation: Ensure that the substrate is clean, dry, and free from dust, grease, or other contaminants. Make any necessary repairs or levelling before applying the adhesive.

b. Mixing: Follow the manufacturer’s instructions for water-to-adhesive ratio. Use a clean mixing container and gradually add the adhesive to the water while stirring continuously until a smooth, lump-free consistency is achieved.

c. Application: Apply the adhesive using a notched trowel, spreading it evenly over the substrate in manageable sections. The size of the notched trowel depends on the tile size and substrate condition, so refer to the manufacturer’s recommendations.

d. Tile Placement: Press the tiles firmly into the adhesive, making sure they are properly aligned. Use spacers to maintain consistent grout lines and adjust tile placement as needed.

e. Cleaning: Remove any excess adhesive from the tile surfaces and grout lines using a damp sponge or cloth before it dries.

f. Grouting: Allow the adhesive to cure according to the manufacturer’s instructions before proceeding with grouting. Use a high-quality grout product suitable for your specific application.
