Substrate Treatment:

The substrate shall be solid, clean, free from shaking, oil stain, wax stain, concrete curing agent and other loose materials; in substrates with high water absorptivity or in high temperature and dry environment, the substrate should be wetted before construction, until it is dry outside and wet inside. The flatness of the substrate should be less than 0.5mm per meter. If this requirement is not met, leveling needs to be carried out first or scrapers with a larger tooth depth should be used.

Preparation of Adhesive Cement:

Add a suitable amount of water into the mixing bucket, and slowly add powder while mixing. The mixing ratio is 20kg powder : 4.2-4.6L water (depending on the convenience of application). Use an electric mixer to mix until there is no caking, place it for 5-10 minutes, and mix it fully again before use. Application should be ideally completed within 1 hour after preparation.

Tiling:

Use a tooth-type scraper to apply the tile adhesive onto the substrate, make it evenly distributed and comb into tooth-like strips. Apply the adhesive over an area of about 1 square meter each time, and softly press tiles onto it during the cooling period. When selecting scrapers with different tooth depths, one should take working surface flatness and tile back concavity into consideration.
