Acrylic pool paints can be applied to damp surfaces
Painting a pool requires careful preparation to achieve a flawless finish. One of the key steps is priming or sealing, which ensures proper adhesion of the new paint to the pool surface. While epoxy paints, the longest-lasting type of pool paint, require the pool to be completely dry before application, acrylic pool paints are more versatile.
However, it is important to note that the pool surface should still be properly prepared before painting with acrylic paint. This includes draining the pool, degreasing and cleaning the surface with trisodium phosphate (TSP) or a similar degreaser, and removing any old, loose paint or debris. Power washing and scrubbing the pool surface with a stiff bristle brush can help ensure that the surface is thoroughly cleaned. Additionally, it is important to tape off any areas that you do not want to paint, such as the tile band, light, and fittings.
Once the surface is prepared, you can apply the acrylic paint using a brush or roller with a maximum nap thickness of 3/8 inch.
