Not recommended
Primer and topcoat are generally not recommended to be mixed. Primer is mainly used to enhance adhesion and waterproof, while topcoat is used to provide color and appearance. Mixing the two may cause the coating performance to deteriorate, affecting weather resistance and aesthetics. In addition, the composition, function and effect of primer and topcoat are different, and mixing them may affect the final effect.
The role and difference between primer and topcoat
Primer: Mainly used to enhance adhesion and waterproof, providing a good foundation for topcoat.
Topcoat: Used to provide color and appearance, with better decorative effect.
Consequences of mixed use
Performance degradation: Mixed use may cause coating performance degradation, affecting weather resistance and aesthetics.
Poor effect: The composition of primer and topcoat is different, and mixing them may affect the final effect, resulting in a decrease in coating quality.
