Hardiplank is a specific brand of fiber cement siding made by James Hardy Inc. Though you can use any type of paint on Hardiplank, some prove more durable than others. Identify the potential drawbacks associated with specific types of paint, or you could end up with a finish that fades or cracks.
Oil-based Paint
Though you can finish Hardiplank with an oil-based paint, the finish may crack. Because petroleum-based finishes are so hard, they tend to crack after a relatively short period of time. They also often turn dull and powdery when exposed to exterior conditions.
Latex Paint
Ordinary latex paint is intended for interior surfaces that don't have to hold up to rain, sleet, snow and direct exposure to ultraviolet sunlight. Though you could use plain latex paint on your exterior Hardiplank, fading will prove almost certain and cracking could eventually result. Latex paint is not engineered with the ability to combat harsh environments. If you use it on exterior surfaces, you must repaint after a relatively short period.
Acrylic Latex Paint
Exterior acrylic latex paint holds up much better than plain latex paint because it is formulated to withstand direct sunlight and is capable of expanding and contracting without cracking as temperatures fluctuate.
Acrylic Paint
Exterior acrylic paint is the best option for Hardiplank. It provides the same benefits offered by acrylic latex paint, but tends to last much longer. Although it is typically more expensive than acrylic latex paint, pure acrylic-based exterior paint is worth the extra cost because it won't require refinishing nearly as often.
Brands
Many amateur do-it-yourself enthusiasts spend extra on specific brands of paint because they recognize their names from commercials. When it comes to selecting a paint for your Hardiplank, disregard advertising and opt instead for a finish that offers a long-lasting warranty.
