Construction requirements
1. The base layer of HG203 must be firm, clean, free of dust, oil, sand, and water. Defects such as cracks should be repaired first, and the male and female corners should be made into arcs.
2. Stir the paint in the container evenly before coating without leaving any sediment on the bottom, then add 20% clean water and stir evenly to apply brushing, scraping or mechanical spraying.
3. The flat surface can be formed at one time during coating. In order to prevent the façade from flowing during one-time forming, a very thin layer can be applied to the base surface. The paint residence time in the container is about 5-10 minutes.
4. (Depending on the site temperature and environment), then construct the required thickness on the base layer at one time.
5. The construction environment temperature should be higher than 0℃.
6. If you need to apply the second coat, you must not step on it after 24 hours (subject to non-sticky feet), and the master is not allowed to step on it before it is fully cured.
Material consumption 1.5kg-2.0kg/㎡ (thickness 1.5mm-2.0mm)
Storage and packaging
1. When storing, the material barrel should be sealed to prevent moisture absorption and mixing of impurities. Store in a ventilated and cool warehouse.
2. The storage period of this product is twelve months, and it can still be used after the storage period has passed.
3. This product is non-flammable. It should be transported to prevent collision, sun and rain, and keep the packaging intact.
4. Sealed and packed in iron drums
5. Specifications: 20kg/barrel, 5kg/barrel, 1kg/barrel.
1. The prepared paint must be used up within 30 minutes. After the construction is completed, HG203 special cleaning agent should be used immediately
