Concrete paint can, and often does, completely alter the appearance of a concrete surface like a garage floor, and it can also serve as a protectant. Walls and floors in porches and garages are two such examples where a this type of coating is desirable. There are various kinds and grades of concrete paint that can be used for your projects.
Water Based Latex Paint
For the least expensive concrete paint option, choose a water-based latex paint. It is very easy to apply and is a good choice if your concrete is new. Easy clean up of painting tools is also a benefit. But water-based latex paint does not provide a moisture-proof seal and is not as durable as other concrete paint choices. If using latex paint on concrete, apply at least two coats for maximum coverage.
Oil Based Paint
Oil-based paints are comparable in price to water-based latex paints, but it provides a more durable finish when applied to concrete. It’s a good idea to apply an oil-based primer for concrete prior to applying the paint because this base will fill in any small holes or pores on the concrete and allow you to start painting on a receptive surface. Be sure you purchase oil-based paint that is made for concrete application. Clean up of your painting materials requires mineral spirits when using this type.
Epoxy Concrete Paint
Epoxy is the premiere choice of concrete paint because it will provide the most durable surface once dried. Be prepared to pay as much as double the price of oil-based or water-based latex paints. It is purchased in two separate cans that are mixed together when the epoxy is ready to be applied. The same features that make epoxy desirable for hardness and durability can also prove to be drawbacks. Concrete painted with epoxy can be slippery and cleanup of paint materials is difficult. Find out about purchasing a non-skid additive if using this paint choice. Epoxy requires excellent ventilation, so if using this paint in an enclosed space, be sure to fully open windows or use exhaust fans.
No matter what your choice is for concrete paint applications, it is essential that before starting any painting project, you properly prepare your concrete surface. Make sure the surface to be painted is clean and dry, free from any debris or previous paint peelings.
