One, whether to apply a topcoat to real stone paint
The surface of the real stone paint must be coated with a topcoat. The topcoat also offers several advantages. Real stone paint has poor weather resistance, rain resistance, and alkali resistance. Applying a topcoat can help protect the real stone paint.
Two. The function of the topcoat for real stone paint.
1、Dustproof, stain-resistant, and scrub-resistant
One important function of a clear coat is to protect against dust, dirt, and abrasion. Without a clear coat layer applied after the textured stone coating, the textured stone coating is highly susceptible to discoloration, water damage, and reduced aesthetic appeal.
2、Extend the lifespan of the main coating.
Topcoat paints have anti-alkali and UV protection properties. For example, exterior stone paints, which are exposed to varying weather conditions, can significantly extend the service life and maintain the aesthetic appearance of the stone paint layer. Without a topcoat, the difference between the painted and unpainted stone paint layer becomes apparent over many years.
Three. What are the consequences of not applying a topcoat to faux stone paint?
The textured effect of genuine stone paint primarily comes from natural colored sand. Without a protective layer of clear coat, genuine stone paint directly exposed to the atmosphere is prone to accumulating dust and rainwater, which can negatively impact its appearance and coating, leading to issues such as water stains, fading, discoloration, sand detachment, and yellowing over time. This affects its weather resistance and service life.
IV. How to apply the topcoat for faux stone paint.
The application method for clear coats typically involves brushing, rolling, and spraying. Brushing is the most economical method, but it is also the most time-consuming. Rolling is more convenient, but it is important to avoid roller marks. Spraying clear coats provides a more natural finish and faster application, saving time and reducing material consumption compared to brushing and rolling, but it can be more difficult to repair and requires more material.
V. important considerations for applying topcoat paint
1、The stone paint coating must be allowed to cure for at least 7 days (at ambient temperature) before applying a topcoat.
2. The optimal construction temperature range is 10-35°C with humidity <80%. Avoid construction in rainy, snowy, or windy weather, as this can lead to uneven film formation and affect gloss and water resistance.
3. Can be applied using roller, brush, and spray methods. The recoating time should be at least 2 hours. The roller should be evenly coated, and excessive re-coating should be avoided, as this can lead to unevenness and affect the decorative finish.
4. If using matte varnish, please thoroughly mix and accurately measure the components before application.
5. Do not mix with other paints, organic solvents, or similar products.
6. Ensure the surface is clean, dry, solid, and free of contaminants before use.
7. If used on existing walls, it is recommended to first clean the old wall surface with a cleaning agent.
