One, will the color of Natural stone finish (genuine stone paint) become darker or lighter after drying?
The color of natural stone paint is significantly affected by humidity, and the extent of the change is difficult to quantify. The color variations also depend on the specific shade. For example, many yellow natural stone paints may appear less vibrant when wet, but darken upon drying. Additionally, some colors, such as blue, may appear very dark when wet but lighten upon drying. When purchasing natural stone paint, it is crucial to select the product based on its dry color, not its wet color. Otherwise, significant color variations will occur.
Two. What should I do if the color of the real stone paint is too light?
1. Inspect whether the appearance of efflorescence and whitening at the bottom of the anti-alkali base coat is caused by insufficient or missed application. If efflorescence and whitening are caused by this, the entire project must be redone.
2. If the white appearance is due to the emulsion not fully drying, this is the initial water resistance of the emulsion. As the temperature rises, the white appearance will automatically return. If you need to quickly restore the original color, after the exterior wall paint has dried, you can try using an oil-based exterior wall paint roller or spraying a second coat.
3. Some white patches are caused by uneven application of stone paint, which appears as white patches when viewed from the side. To fix this, first find a small area and re-apply the stone paint over the existing white patches. After drying, check if the color is consistent. If so, you can apply the stone paint over a larger area.
4. The addition of aggregates (such as common marble or limestone powder) or fillers (such as common calcium carbonate or titanium white powder) to the formulation of genuine stone paint can also cause the paint to appear lighter after drying. For whitening caused by this reason, the only solution is to redo the work. When designing the formulation, it is necessary to consider the balance between covering and the resulting consequences. One should not simply increase the covering by adding aggregates or fillers.
