How to maintain multicolor stone-like paint on a daily basis?

Colorful stone-like paint is also known as 'liquid stone'. It is an architectural coating made by crushing natural colored sand and gravel. When used to imitate natural stone, it is highly similar in both color and texture. The spraying effect can present the natural veins and textures of stone materials such as marble and granite, making it suitable for the interior and exterior decoration of various buildings. Next, let’s take a detailed look at the knowledge of Runli stone-like paint.

I

1. Origin of colorful stone-like paint

Colorful stone-like paint is a water-based exterior wall multi-color coating processed with modern technology, using acrylic silicone resin emulsion and fluorocarbon resin emulsion as basic raw materials, combined with inorganic pigments and high-performance additives.

2. Features of colorful stone-like paint

The coating of Runli stone-like paint becomes very hard after construction and drying, and cannot be scratched off with fingernails. The coating has good water resistance, stable coloring, no whitening, and no color difference. Colorful stone-like paint features rich and varied colors, providing infinite aesthetic appeal with strong simulation effect. Its surface presents a three-dimensional effect and multi-color decorative beauty that cannot be replaced by any other coating.

II. Precautions for the construction of colorful stone-like paint

1. A reliable and experienced construction team should be selected before construction. A professional construction team is one of the key factors for project quality.

2. Suspended platform spraying is recommended for construction. Spraying with scaffolding tends to leave joint marks after construction, increasing construction procedures.

3. As colorful stone-like paint is transported in large-size packages, sedimentation may easily occur. Therefore, the paint should be fully stirred evenly before use.

4. The construction of colorful stone-like paint shall be carried out at a temperature between 5℃ and 35℃, with humidity maintained at 60%-70%. Construction is not allowed on rainy days, and it must be ensured that the sprayed surface will not be exposed to rain within 24 hours after spraying.

5. A coverage rate test shall be conducted according to on-site conditions before construction to prevent sand falling off the wall during construction. The air pressure of the air compressor shall reach above 8kg when spraying the wall.

6. Uneven spraying often causes mottling during the application of colorful stone-like paint, resulting in color inconsistency between thick and thin sprayed areas. Multiple passes of thin spraying and gradual forming are recommended during construction, which can effectively avoid wall mottling.

7. Since the raw material of colorful stone-like paint is natural colored sand and gravel, slight color difference may exist between different batches. Therefore, the same batch of paint shall be used for construction, and a certain amount of the same batch shall be reserved for color difference repair. Meanwhile, attention shall be paid to avoiding intermittent construction and color difference caused by lighting.

8. The pH value of the wall surface shall be tested before construction to prevent alkali efflorescence of concrete. If a topcoat is required, it must be applied evenly by rolling or spraying; otherwise, the topcoat will accumulate in grooves and cause whitening and mottling on the wall.
