the act of Painting a house over old paint It is a process that requires careful attention, as the original surface may be deteriorated or have residual paint that affects the adhesion of the new paint. If the surface is not properly prepared, it may lead to problems such as peeling paint, fading, or mold stains later on. One of the important steps that should not be overlooked is ” Using primer on old plaster“
The benefits of old cement primer.
- Enhances the adhesion of topcoat paint: The old cement primer acts like an adhesive that bonds the surface between the old paint and the new paint, allowing the new paint to adhere better than before and reducing the chances of the paint peeling off in the future.
- Extend lifespan: The addition of a primer layer helps prevent moisture and chemicals from the original surface from seeping into the new paint layer, making the topcoat more durable.
- Reduce fading issues: The primer helps to even out the surface, resulting in a more uniform application of the new paint and reducing the chances of uneven color shades.
- Prevents stains, mold, and algae: Old concrete walls often accumulate moisture. If suitable underlayment is not used, it may lead to problems with mold, water stains, and moss in the long term.
- Reduce chemical reactions: The old cement primer helps reduce the reaction between the chemicals in the old paint and the new paint, which may cause the paint to deteriorate faster than normal.
