What details should be noted when selecting stone-like paint?

Stone-like paint is generally a viscous liquid mainly made of resin or oil, with or without pigments and fillers, and formulated with organic solvents or water. New varieties of natural stone-like paint in solid form have also appeared, such as powder coatings. Regardless of their form (liquid or solid), all types of coatings generally consist of at least two or three basic components: film-forming main materials, secondary film-forming materials, and auxiliary film-forming materials. Coatings are liquid or solid polymer materials that can be applied to the surface of a substrate to form a tough and continuous coating film. Formerly known as lacquer or varnish, they are mainly used to decorate and protect the coated surface. Some coatings also have special functions, such as high temperature resistance, cold resistance, and radiation protection. Coatings are widely used in construction, ships, vehicles, metal products and other fields.

Choosing coatings for decoration is not an easy task, as you need products with good quality, reliable brands, and environmental friendliness. When buying building materials, the biggest concern is being sold shoddy goods as high-quality ones. However, as long as you are careful enough, any inferior product will reveal its flaws. Just pay attention to these 9 details when selecting:

1. Choose official sales channels: Try to buy from reputable formal markets or specialty stores. According to recent supervision and random inspections by the municipal bureau of quality and technical supervision, the sampling pass rate of interior wall coatings sold by these enterprises is relatively high.

2. Select professional brands: You don’t necessarily have to buy the most famous brands, but you must choose professional ones.

3. Check the aqueous solution: Coatings will separate when standing still. The top quarter is an aqueous solution. If the solution is colorless or slightly yellow with little floating matter, the coating quality is good.

4. Check particle fineness: Put a small amount of coating into a glass of clean water. After stirring, if the water remains clear, the particles are independent without agglomeration and uniform in size, the quality is good.

5. Test the filament drawing: Dip a stick into the latex paint. Good paint can form long, continuous and evenly falling filaments.

6. Feel the texture: Dab some coating with your finger and rub it. Good paint has no rough sand particles and feels smooth when rinsed with water.

7. Smell the odor: Eco-friendly coatings should be water-based, non-toxic and odorless. Do not buy coatings with added fragrances, as additives may also be non-environmental.

8. On-site test: Apply the coating on a cement floor. After drying, wipe it with a damp cloth. High-quality products remain bright and new, while inferior ones fade.

9. Check the production date: Always check the production date and shelf life. Never purchase expired coatings.
