If you are looking for waterproof paint for cement board, there are a few things that you need to know.
What should I know about this?
The first thing that you should know about waterproof paints is that they are typically not necessary if the concrete board being used has already been coated with sealant or primer before installation. If this is the case, then water-based latex paints can be applied directly to these products without any problem!
Before painting, waterproofing your board is best done with an oil-based product such as linseed oil or mineral spirits. These oils waterproof the cement board by penetrating tiny pores and fractures that may be present in your cement board. When this waterproof layer dries, it is typically a very dark color, so you will want to apply a light-colored primer before painting with latex paint.
– paints should not be used on unfinished concrete surfaces because they can trap moisture within the surface of the concrete, which could create problems down the road such as mold growth or damage from freeze-thaw cycles.
