Which Exterior Paint Is Best For Cement Board?

Painting a whole home can be a demanding task, especially when it comes to Hardie board siding. Hardie plank, also known as fiber cement siding, is a newer composite material made of concrete substrate. It is extremely durable and lightweight, making it an excellent choice for exterior building materials. Sherwin Williams offers several excellent options for topcoating Hardie board siding, such as Loxon Self-Cleaning Paint and 100 acrylic or acrylic latex paint.

For fiber cement siding, it is recommended to use 100 acrylic or acrylic latex paint, which are specifically designed to adhere well to cement boards. Sherwin-Williams, Benjamin Moore®, and Dunn-Edwards sell acrylic paint that is compatible with cement board siding. For the best results, apply two coats of paint, usually using Sherwin Williams Emerald paint or Benjamin Moore Regal Select.

Sherwin-Williams Loxon Conditioner and Acrylic Coating is a product line well-suited for fiber cement and other masonry surfaces. Superpaint is recommended for Hardie siding, and if a primer is applied, you will be well protected. Acrylic latex paint is recommended for Hardiplank siding due to its excellent adhesion properties and long-lasting finish. Sherwin-Williams’ Duration Exterior Acrylic Coating is an excellent choice for Hardie siding.

Although acrylic latex paints are the first choice due to their versatility and suitability for a wide range of uses, two coats of high-quality, 100 acrylic exterior paint can look beautiful for up to two decades when applied properly and with proper prep work. Benjamin Moore MoorGuard exterior is a good option, but it may be expensive if not paying for it. Sandtex masonary paint has been used for cement fiber board soffitts on a house for a couple of years and still looks as good as when done.

Can you paint directly on cement board?

Cement boards can be painted due to their pores, which make them easier to absorb paint than traditional cement. However, it’s crucial to know the right paint type, how to prepare the siding for painting, and how often to repaint the board for optimal results. Painting cement boards isn’t as straightforward as painting interior walls, so it’s essential to have the necessary knowledge. Before painting, wash the siding from the top down, inspect the caulking, and repair any cracks, splits, or holes. Repair kits start at around $15, or hiring a professional can be a more cost-effective solution. When painting, work from top to bottom and follow the grain.

How many coats of paint on cement board?

Sherwin-Williams Duration® Exterior Latex Coatings are the top choice for new fiber-cement siding due to their high film build and guarantee against peeling or blistering. Other high-quality exterior latex paints, like Loxon Masonry Topcoat, require two coats and can be brushed, rolled, or sprayed. When repainting fiber-cement siding, use a pressure clean with a minimum of 2100 psi pressure to remove dirt, dust, grease, oil, loose particles, foreign material, and defective coatings. Rinse thoroughly, scrape away any remaining paint, and sand glossy surfaces to make them dull. A primer is not needed unless the substrate is exposed, and one coat of Duration is all that is needed.

Do you have to prime cement before painting?

Primer is essential when painting concrete to prevent paint from soaking into the surface and provide added adhesion. If painting a bare concrete wall, primer is necessary, but not for previously painted surfaces. Emperor Masonry Paint Primer is recommended due to its super hydrophobic technology and compatibility with the paint. Apply one coat of primer and let it dry completely for 3-5 hours.

When painting exteriors, consider the weather conditions, especially in the US. Avoid painting in conditions below 5°C, as water-based masonry paint will not dry in these conditions, and above 20°C, as it can cause the paint to dry too quickly. Create shade if possible and avoid painting in direct sunlight. Using Emperor Masonry Paint Primer ensures a smooth and long-lasting finish.

A primer is essential for adhering paint to fibre cement cladding, preventing future peeling and creating a smooth surface. Apply at least one coat before painting. After cleaning and priming, paint can be applied using a paintbrush, paint roller, or paint sprayer. Use a paintbrush for corners and trim near the top and bottom of the cladding, or a paint roller for the entire surface. While it is possible to paint fibre cement cladding yourself, hiring a professional is recommended if you don’t have the time to complete the project on your own.

Should I prime a Hardie board before painting?

Before painting Hardie Board siding, it is essential to prime it to improve paint adhesion and finish. Primer seals the surface of the siding, preventing moisture penetration and damage. Choose a primer specifically designed for fiber cement siding, as it provides a good base for paint to adhere to. It is also recommended to choose a primer compatible with the type of paint being used. This ensures a better adhesion and prevents moisture penetration.

Do cement boards need priming?

To install plasterboard or plaster on stud walls, locate existing studs and mark them. Install the boards vertically or horizontally, leaving a 3mm gap between floor and wall edges. Fill this with silicone sealant. Fix stainless steel screws at 200mm centers and every 200mm down each stud. Cover the joints with alkaline-resistant tape. Prime the board’s face with a suitable primer if using a cement-based adhesive, or no priming if using a ready-mixed adhesive. Use 12mm HardieBacker boards when fixing tiles to stud walls. Follow these easy steps to install backer board onto stud walls.

Fiber cement siding is a durable material, but selecting the right paint can be challenging. Many homeowners are concerned about the longevity of the paint and the potential for chipping off.

Benjamin Moore Cement Board Primer is a cement board primer that is particularly effective for fiber cement siding. Behr Premium Plus Exterior Paint and Primer in One is favored for its excellent coverage and ease of use. By understanding the specific needs of your fiber cement siding, you can make the best choice for your home’s durability and curb appeal.

Do I need to seal cement before painting?

Masonry surfaces should be sealed and primed before painting to prevent moisture from seeping through the concrete or masonry. This is particularly important in basements, where water may condense under plastic wrap. A quality masonry sealer with a separate primer is recommended to create a strong, water-resistant foundation for the final painting.

Painting should be done after the sealer and primer coats have dried out. A brush is preferred for detail work around windows and trim, while rollers can be used for the rest of the painting. The manufacturer’s recommendations should be followed for the appropriate nap size, typically ¾-inch or 1-inch. A minimum of three roller covers should be purchased for the sealer, primer, and paint.

The exterior painting should be completed within 90 days of installing the James Hardie Fiber Cement Siding for optimal results. Sherwin Williams Exterior Emerald RAIN REFRESH is an excellent choice for this project.
