Product Overview
Meilijia Black Sealer [DY007] is a primer specifically formulated for multi-color stone-effect coating systems. It has been optimized to meet the application characteristics and protective requirements of stone-effect paints, providing direct contact with the substrate and performing critical functions such as alkali resistance, sealing, reinforcement, and seamless transition between layers—thereby fundamentally ensuring the stability of the stone-effect paint system.
Product Features
- Highly alkali-resistant and breathable balance
- Base reinforcement and enhanced adhesion
- Closed pores, waterproof and moisture-proof
- Highly adaptable and environmentally friendly
Scope of Use
It is primarily used for alkali-resistant and sealing/curing treatment of the substrate prior to the application of stone-effect paint, effectively protecting the topcoat from chemical attack by substances within the wall. During the black-line application process, a black primer can replace the black line paint, reducing the number of construction steps and shortening the project schedule.
How to Use
Product Use: Simply open the lid, stir well, and use.
Construction tools: wool roller or pressure sprayer specifically for multi-color stone-effect coatings
Product dilution: Dilute with water at 10–30% based on actual usage.
Specification Standards
Theoretical consumption: 0.1–0.12 kg/㎡
Product specifications: See the product certificate of conformity.
Product color: Black
Implementation Standard: GB/T 9755-2024
Precautions
- To ensure optimal wall coating performance, it is strongly recommended to use this product in conjunction with the Meilijia system. Mixing this product with products from other brands is strictly prohibited.
- Prior to construction, inspect the substrate, remove surface dust, efflorescence, and any contaminants, and ensure the substrate is sound, clean, and dry; the wall’s moisture content must be less than 10%, and its pH value must be less than 10.
- Construction shall be carried out at a temperature no lower than 5°C and relative humidity no higher than 85%; construction is not recommended in rainy, snowy, or high-temperature conditions.
- During construction, implement appropriate protective measures to prevent skin and eye contact with the product.
- This product can be diluted with water according to site conditions. It is recommended to dilute with 20–30% water in summer under high temperatures and with 10–20% water in winter, to ensure thorough penetration of the primer and complete reinforcement of the substrate.
- If spray application is used, follow up with a long-nap roller to ensure even coverage after spraying; only proceed to the next process step after the coating has fully dried and passed the tape adhesion test.
- Consumption varies depending on the actual roughness of the construction surface and the dilution ratio.
- The degree of product drying is influenced by ambient temperature, humidity, and ventilation. At room temperature, drying typically takes 6–8 hours; in winter or during humid weather, the drying time should be appropriately extended.
- Keep out of reach of children;
- Storage: 12 months (store in a sealed container in a cool, dry place);
- Transportation: This product is not a hazardous chemical and may be transported as ordinary cargo.
- For the product’s implementation standards, batch number, date of manufacture, inspector’s name, and shelf life, please refer to the Certificate of Conformity.
