True Stone Paint application involves multiple stages, with one of the early steps being the preparation of the substrate to meet the requirements for True Stone Paint application standards.

Base requirements

Cement sand mortar powdering and maintenance for more than 15 days at a one-to-three ratio offers several significant benefits: first, it serves to level surfaces; it also acts as a bonding agent, such as for tiling floors. Additionally, it provides a protective layer and helps in finding slopes, among other functions. The powdering surface should be flat but not too smooth, and the cut corners should not be too sharp.

Before the application of the natural stone paint, the cement surface or the surface to be coated must be free of moss, grease, or any other contaminants. If any are present, they must be completely removed to ensure proper adhesion, and the surface must be kept sufficiently dry.

3. If the surface is coated with old paint, it must be tested or confirmed as adherent before application. Otherwise, it must be scraped off.

Cleaning Method

How to quickly clean the subfloor? Here are several practical methods:

Scrape

This is the traditional and effective method for most flat surface treatments, whether it's gypsum and wallboards or wood and black metals. Triangle or elliptical scrapers are suitable for scraping corners and circular contours. Be cautious not to gouge, as it may damage the surface. First, sand all rough edges with medium garnet sandpaper, then finish with fine sandpaper.

Scrub with a wire brush

Use a stiff wire brush, being careful not to damage the base material. Once all loose paint has been removed, first sand the surface with medium石榴石paper, then finish with fine sandpaper.

Polish

If the coating has only slight peeling, you can simply sand it down in the order of coarse, medium, and fine sandpaper.

Chemical Stripper

Select a paint stripping agent suitable for coating and substrate treatment, following the manufacturer's recommendations. Allow ample reaction time for the stripping agent, typically 15-20 minutes or longer, depending on the thickness of the old paint film. Gently remove the softened paint film using a scraper or wooden spatula, and scrape it into the double-layered trash bag inside the cardboard box. Apply another layer of stripping agent if necessary, and then clean the surface with paper towels, newspapers, or a cleaning pad.
