1. Construction Environment Requirements
1) High-altitude construction (above 2 floors) with wind force less than level 5;
2) Construction temperature must be greater than 5℃ and less than 35℃;
3) Air humidity ≥ 85%; construction cannot be carried out on rainy days; after rainy days, construction cannot be carried out if the wall has not dried (at least 2 days of drying).
4) Construction should be stopped immediately in rainy weather.
2. Safe Construction and Precautions
1) All construction personnel must strictly adhere to safety construction procedures and stone texture paint construction procedures. Strengthen safety awareness and quality awareness.
2) Before using external scaffolding or hanging baskets, a safety inspection of the overall structure should be conducted, and it can only be put into use after passing the inspection.
3) When working on scaffolding or hanging baskets, materials such as stone texture paint and small tools should be placed in secure locations to prevent falling objects from injuring people.
4) Timely understand the construction progress, adjust the detailed plan, and ensure the technical quality of the construction.
5) After construction is completed, all site facilities and other temporary facilities should be dismantled in a timely manner as required, and materials should be removed from the site.
3. Meihui Stone Texture Paint Construction Process
1) Preparation Work
Set up scaffolding or construction hanging baskets, ensure construction personnel are in place, and prepare tools (scrapers, trowels, rollers, brushes, masking tape, wires, spray guns, sockets, protective covering paper or plastic film, air compressors, etc.).
2) Substrate Inspection, Cleaning, and Leveling Treatment
For the base cement mortar construction of building walls, combined with the construction process design of stone texture paint:
Inspect building roofs, gutters, and other areas that are long-term in water environments. For example: whether the roof parapet and its corners have waterproof details, or whether waterproofing is required in the future. These areas are one of the main causes of wall efflorescence and water seepage.
① After the roughening treatment of the base cement mortar construction, the wall must undergo natural drying (with a flatness drop of less than 12.5px), generally for more than 28 days;
② Check if the wall is loose, oily, or unclean; if found, it must be removed, and the mortar should be reapplied and roughened.
③ Before applying stone texture paint, attention must be paid to the acidity and alkalinity of the wall, which is generally more suitable when neutral. If it is highly alkaline, treatment of acidity and alkalinity must be carried out. Neutralization can be done with clean water or oxalic acid.
④ Before applying stone texture paint, remove the scaffolding connected to the wall and reinforce the scaffolding, paying attention to wall repairs.
3) Stone Texture Paint Construction Details
For the external wall construction of new building walls, the Meihui stone texture paint construction method is as follows:
4) Construction Precautions
① For the closed paint roller application, dilute with 30% water for construction, dry for 2-3 hours, and extend the drying time on cloudy days;
② Draw lines, apply black paint for lines (Meihui special black paint for jointing), wait for the black paint to dry thoroughly (at least 12 hours, the drier the better) before applying masking tape for the lines;
③ Roll on two coats of Meihui stone texture paint primer, with a re-coating interval of 4-6 hours; dry for 8-10 hours after construction;
④ Spray two coats of stone texture paint, ensuring uniformity and consistency of the spray effect, and immediately remove the masking tape after spraying, drying for more than 24 hours;
⑤ After the stone texture paint mid-coat is dry, spray two coats of Meihui stone texture finish paint, with an interval of about 4-6 hours between each coat, ensuring no missed spots.
