JIASHILI exterior real stone paint construction process: excellent stone-like effect and outstanding weather resistance

<h2>Base treatment is the core prerequisite for exterior real stone paint construction</h2><p>Many construction teams often skip the base cleaning step to meet deadlines, resulting in peeling and cracking of real stone paint within half a year—a problem that can easily be avoided. Take JIASHILI exterior real stone paint as an example: before construction, surface dust, oil stains, and loose old paint must be removed. Holes or cracks should be filled with special repair mortar, and once dry, the surface should be sanded until its roughness reaches 20-30μm, ensuring strong adhesion between the real stone paint and the base. In a sample project we did at a high-end residential complex in Guangzhou last year, the real stone paint remained intact after over two years thanks to proper base treatment, with no signs of peeling.</p><img src="/images/news/news-2-1.png" alt="Exterior real stone paint spraying construction, workers using spray guns to apply stone-like exterior walls" /><p>After base treatment, a dedicated primer must be applied—this step cannot be skipped. The primer recommended by JIASHILI has a solid content of over 45%, and the application thickness should be around 0.15mm. This prevents alkali eruption caused by moisture penetration and enhances the adhesion between the real stone paint and the wall. We compared samples with and without primer: the wall without primer showed local discoloration after three months, while the primed wall still has uniform color today.</p><h2>Spraying technique determines the final stone-like effect of real stone paint</h2><p>Spraying real stone paint is the step that most tests a worker’s skills; pressure, gun distance, and moving speed must be strictly controlled. The standard parameters provided by JIASHILI are: spraying pressure set to 0.4-0.6MPa, the distance between the spray gun and the wall kept at 30-50cm, and the moving speed of the gun stabilized at 15-20cm per second. Only in this way can the coating thickness be evenly 2-3mm, producing a texture highly similar to natural stone. In a villa project in Foshan last month, the workers followed these parameters precisely, and the sprayed result was mistaken for natural granite by the homeowner, who immediately decided to adopt this process for the entire community.</p><img src="/images/news/news-2-2.png" alt="Finished effect of real stone paint exterior wall, with stone texture appearance" /><p>Do not leave the site right after spraying; first check for any missed spots or sagging areas and touch up promptly. After the surface dries, apply two coats of topcoat varnish. JIASHILI’s topcoat varnish has a weather resistance of over 10 years, effectively protecting against UV radiation and rain erosion, keeping the stone-like effect of the exterior wall vibrant for a long time. According to our tracked past cases, the probability of peeling or fading for exterior walls constructed with this process is less than 2% within ten years.</p><h2>Regular maintenance can also extend the service life of real stone paint</h2><p>Even with perfect construction, exterior real stone paint requires regular maintenance to stay in optimal condition. It is recommended to clean the wall once in spring and once in autumn using a low-pressure water gun—never use a high-pressure water gun, as it may wash off the varnish layer on the surface. If there are minor scratches on the wall, simply sand them gently with fine sandpaper and touch up with a layer of varnish to restore the original look. JIASHILI also offers a special repair kit for such maintenance needs, which is easy to use and can even be handled by ordinary homeowners.</p>
