Surface Preparation and Application Guide

Surface Preparation

• Ensure the ceramics are well-adhered so they do not move during application, and pay attention to ensure the adhesive is completely dry.

• Thoroughly clean any dust, dirt, sawdust, construction, and cement residues remaining inside the joint gaps using a thin stick or brush.

• Ensure that the joint gaps are at least 2/3 of the ceramic thickness.

• Moisten the cleaned gaps with the help of a wet sponge.

Application

• Fill the joints using a squeegee with a hard rubber tip or a joint spreading trowel with a hard rubber base.

• Apply the material first parallel and then crosswise to ensure the gaps are filled thoroughly.

• Scrape off the excess mortar on the surface using a dampened soft-tipped spatula, wait 15–30 minutes depending on the ambient temperature, and then wipe with a damp sponge to thoroughly clean any thin joint film remaining on the surface.

• Do not start the joint wiping process prematurely.

• Avoid wiping with an excessively wet sponge to prevent color fluctuations.

• Clean the sponge being used at frequent intervals.

• Walls dry after 12 hours, floors can be walked on after 24 hours, and they can be opened to pedestrian traffic after 7 days.
