1. Basic Treatment Aspect
1. Ensure that the substrate is dry, solid, flat, and free of standing water before construction. The substrate strength should be greater than or close to the strength of the putty powder.
2. Before construction on old walls, remove paint, oil stains, hollow shells, and floating dust, and perform sealing and curing alkali-resistant treatment.
3. For relatively smooth substrates, it is recommended to treat them with tile renovation putty or interface agent before construction.
4. Walls with severe efflorescence or standing water cannot be constructed directly.
5. Highly absorbent or dry substrates should be moistened before construction.
2. Explanation of the Troweling Process
1. The construction environment temperature and drying process temperature should be above 5°C, and humidity should be below 85%.
2. Pour this product into an appropriate amount of clean water in proportion (1:0.38), stir evenly until there are no granules, and let it sit for 5 minutes before stirring again for use. (To ensure even mixing, a low-speed high-power electric mixer should be used.)
3. Use a special plastering trowel to apply 2-3 coats, with a single coat thickness of 0.5mm-1.5mm, depending on the flatness of the substrate. Applying too thickly in one go may lead to cracking.
4. The interval between each application should be 4-6 hours (depending on environmental temperature and humidity), and each layer should be allowed to set before timely sanding (48-72 hours).
5. When the climate is too dry or windy, maintenance measures should be taken.
