Which Paint Is Ok For Outdoor Concrete?

Concrete surfaces can be painted, including interior floors and walls, as well as exterior surfaces like patios, sidewalks, and pool decks. To paint outdoor concrete, select the right paint, such as acrylic-based paint or concrete stain. Clean and prepare the surface by removing dirt, repairing cracks, and etching the concrete. Apply a concrete primer, and choose between acrylic and epoxy paints.

Acryl latex paint is a water-based product that mixes and spreads, while oil-based exterior paint has traditionally been the strongest and most durable finish. However, latex and acrylic paint have improved, making them more environmentally friendly. Oil-based paint has a high-gloss finish that can stand up to the elements, dries quickly, and is scuff- and peel-resistant. Emperor Masonry Paint is a specially designed silicone masonry paint suitable for use on any exterior walls, including concrete. Sherwin-Williams Porch and Floor Enamel is a popular choice for painting concrete porches, as it is durable, water-resistant, and completely waterproof.

DRYLOK Latex Concrete Floor Paint is a paint-and-primer solution specifically formulated to beautify and protect both interior and exterior concrete. Dulux Trade Line Marking Paint or Coo-Var Low Odour Line Marking Paint are recommended for exterior concrete floors due to their excellent scuff resistance. High-quality exterior-grade paint with weather resistance is essential for outdoor concrete, and an exterior epoxy will reduce the need for touch-ups and repairs. Epoxy paint is an extremely durable, long-lasting cement sealer paint that can take harsh conditions.

For painting concrete, it is recommended to use masonry paint, usually containing acrylic resins, which offer durability, adhesion, and low maintenance costs.

Can I use regular exterior paint on concrete?

To prevent cracking and peeling of concrete, opt for masonry paint or driveway paint, which is thicker and requires special equipment for application. Use masonry paintbrushes and rollers with long arms or extenders for larger areas. Mix masonry paint thinner with the paint for the first coat, then apply it smoothly and evenly. Allow the paint to dry for several hours before applying the second and subsequent coats. Concrete sealant, available in glossy or matte finishes, can be applied with a brush or roller.

A second coat may be necessary in areas with heavy vehicle or foot traffic or frequently moved furniture, such as driveways, swimming pool surrounds, or patios. This will ensure the paint lasts longer and prevents cracking and peeling.

What kind of paint for exterior concrete?

Concrete porch and patio paints are typically low-luster acrylic latex, designed to conceal imperfections and resist fading, scuffing, cracking, and ultraviolet (UV) damage. Epoxy-based paints offer high durability and stain resistance.

Can I paint straight onto concrete?

Concrete patios can be painted, but they cannot be painted using any generic paint. Masonry paint is designed for vertical concrete and brick walls, and it is not suitable for outdoor concrete patios due to its moisture content. To paint a concrete patio, check the moisture levels using a moisture reader, as above 10 is too wet for paint to adhere. If a moisture reader is unavailable, put metal or plastic down on the concrete overnight.

To paint a concrete patio, you will need Rust-Oleum 7200 Floorcoat, floor degreaser, exterior filler and sandpaper, a long pile paint roller and extension pole, a paint tray or kettle, and a stiff brush. Dirt and grime are easily collected by concrete patios, so it is essential to clean the surface first. Clear the patio of furniture and sweep the surface using a garden brush to remove large amounts of leaves and dirt.

Scrub any dirt or grease from the concrete using warm soapy water and a stiff brush. For a deep clean, use an anti-fungal cleaner like Emperor Masonry Cleaner to kill any fungus that can bloom underneath the paint film, ensuring long-term results.

Can I paint directly onto concrete?

Painting directly onto concrete requires proper preparation to achieve the best results. Spending extra time at the start can prolong the surface’s freshness, especially in heavy traffic areas like garage floors. Applying paint directly requires at least two coats, mixing the first coat with a thinner, usually around 20, to create an even finish. The first coat should be used as a primer, while an extra coat or two ensures even coverage. Preparing a floor is a straightforward process if following these steps.

What paint will stick to concrete?

For optimal results, use specialist concrete paints like epoxy for bare concrete floors and quality masonry paint for walls. Spray paint concrete with a single pack floor paint, and apply using a brush or roller. Different concrete paints are better suited for specific areas, such as stairs with a non-slip, textured finish, or outdoor areas with UV protection and weather resistance. For stairs, opt for a non-slip paint for better grip, and for walls, opt for a quality masonry paint.

What happens if you paint concrete without primer?

Priming a concrete surface is a critical step in any concrete painting project. It prevents the formation of imperfections in the finish, such as peeling and cracking, which can otherwise occur over time. This ensures a long-lasting and durable finish.

Do I need to prime exterior concrete 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.

How to paint outdoor concrete?

Concrete is a popular material for building floors and walls, but it is also becoming popular for interior flooring. It is susceptible to moisture due to its water content, Portland cement, and aggregate material. When water absorbs water, concrete expands and retracts, causing cracks. Factors like ambient relative humidity, concrete mixture, geographic climate, aggregate materials, and vapor retarders can affect the rate of concrete moisture evaporation.

This presents a challenge when preparing concrete for paint, and the process can vary slightly depending on whether the concrete is old, new, or being repainted. To prepare concrete for painting, follow these seven critical steps: clean the area, apply an etching solution, fill all cracks, apply concrete sealer if desired, perform a thorough wash and moisture test, purchase the right paint, and apply two coats.

Is painting outdoor concrete a good idea?

Painting versus staining is a popular choice for concrete patios due to its ease of DIY and ability to cover up discolorations and stains. However, painting is less durable than staining, as it can fade, chip, and be damaged over time. The choice depends on factors such as time and resources to hire a professional for staining and the level of durability required. Mild climates may not be affected by painting, while harsh winters or frequent use may necessitate staining.

Regardless, both methods will result in an updated, unique patio that will be enjoyed for years to come. Ultimately, the choice between painting or staining will depend on the specific needs and climate.

Can I paint straight on to concrete?

Painting directly onto concrete requires proper preparation to achieve the best results. Spending extra time at the start can prolong the surface’s freshness, especially in heavy traffic areas like garage floors. Applying paint directly requires at least two coats, mixing the first coat with a thinner, usually around 20, to create an even finish. The first coat should be used as a primer, while an extra coat or two ensures even coverage. Preparing a floor is a straightforward process if following these steps.

Do I need to seal concrete 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.
