What Kind of Paint Do You Use on Rough Concrete
When painting rough concrete surfaces, it is important to use a paint specifically formulated for concrete.
Masonry paint, also known as elastomeric paint or elastomeric wall coating, is recommended for its ability to expand and contract with the concrete.
This type of paint is thicker and can be tinted, providing a durable and long-lasting finish.
Additionally, it is essential to clean the concrete surface before painting to remove dirt, grease, and oil.
Efflorescence, peeling or blistering paint, and moss should also be addressed prior to painting.
Sealing the interior concrete is necessary to prevent moisture seepage and mold growth.
Using a concrete primer to fill pores and even out the surface is recommended.
Finally, allow the paint to dry thoroughly between coats and choose products specifically designed for concrete, such as DRYLOK® Latex Concrete Floor Paint and DRYLOK® E1 Latex 1-Part Epoxy Concrete Floor Paint.
Did You Know?
1. Did you know that rough concrete surfaces can be painted with a unique type of paint called masonry paint? This specially formulated paint is designed to adhere to the texture of rough concrete, providing a durable and long-lasting finish.
2. Don’t be surprised if you find out that masonry paint can also work wonders on other porous surfaces like brick, stucco, and even stone. Its composition allows it to penetrate the surface, bonding tightly and preventing peeling or flaking.
3. For a more artistic touch, there’s another type of paint known as concrete stain, which can be used on rough concrete surfaces. Concrete stain creates a beautiful, translucent color effect while still allowing the natural texture and imperfections of the concrete to shine through.
4. If you’re looking for an environmentally friendly option, you’ll be glad to know that there are now eco-friendly concrete paints available on the market. These paints are low in VOC (volatile organic compounds) and pose fewer risks to both human health and the environment.
5. When it comes to selecting the color of the paint for rough concrete, keep in mind that lighter shades of paint tend to reflect more sunlight, reducing heat absorption. Therefore, lighter colors are generally recommended if you want to help keep the area cooler during hot weather.
Cleaning The Concrete Surface
Painting rough concrete surfaces can be quite challenging due to their porous nature. Before applying any paint, it is crucial to clean the concrete thoroughly to ensure proper adhesion and longevity of the paint job.
To begin the cleaning process, it is essential to remove any dirt, grease, and oil from the concrete surface. One effective method is to use a pre-paint cleaner, such as trisodium phosphate or Krud Kutter’s pre-paint cleaner. These cleaners are specifically formulated to tackle tough stains and provide a clean surface for painting.
In addition to removing surface contaminants, it is also important to address any vegetation growth on the concrete surface. Vines and moss can create an unsightly appearance and can affect the paint’s adhesion. Ensure that any vines or moss growing on the foundation are removed before proceeding with the painting process.
- Clean the concrete thoroughly before painting.
- Use a pre-paint cleaner to tackle tough stains.
- Remove any vegetation growth to ensure proper adhesion.

Removing Vines And Moss
When painting rough concrete surfaces, it is important to deal with vegetation growth like vines and moss. These organic materials can harm the appearance and durability of the paint job.
To effectively get rid of vines and moss, it is recommended to manually scrape or brush them off the concrete surface. Start by using a stiff wire brush or a paint scraper to remove as much of the growth as you can. If needed, a power washer can be used on outdoor surfaces for extra cleaning power.
Dealing With Efflorescence
Efflorescence is a common issue encountered when painting rough concrete. This phenomenon refers to the formation of a white powder on the surface of moist concrete, which can be unsightly and negatively impact the paint’s adhesion.
To address efflorescence, there are specialized products available that can effectively remove the white powder. One option is to use Krud Kutter Concrete Clean & Etch or a phosphoric acid masonry cleaner. These cleaners are specifically designed to dissolve and remove efflorescence from concrete surfaces, providing a clean and suitable base for painting.
Stripping Peeling Paint
If you notice peeling or blistering paint on your rough concrete surface, it is essential to address this issue before applying a new coat of paint. Peeling or blistering paint can be unsightly and indicate underlying problems with the concrete.
To strip peeling paint, you can use a wire brush, paint scraper, or a power washer for outdoor surfaces. Carefully scrape or brush away the peeling paint, ensuring that the surface is smooth and free from loose paint particles. This step is crucial to ensure proper adhesion of the new paint and achieve a long-lasting finish.
Sealing And Priming The Concrete
Sealing and priming the rough concrete surface is a crucial step in the painting process. Sealing the interior concrete is particularly important to prevent moisture seepage and mold growth. One recommended product for sealing interior concrete is ThoroSeal, a high-quality masonry sealer.
When applying the sealer, it is generally necessary to use two coats for optimal protection. After applying the first coat, allow it to cure for five to seven days before applying the second coat. This curing time ensures proper adhesion and enhances the longevity of the paint job.
In addition to sealing, it is also important to apply a concrete primer, also known as a block primer. The primer helps fill pores in the concrete and evens out the surface for better paint adhesion. Behr’s Concrete and Masonry Bonding Primer is an excellent choice for both exterior and interior concrete surfaces. This primer dries in just two hours, allowing for efficient progress in the painting process. Painting should be done within 30 days after priming to maintain the primer’s effectiveness.
Reminder: Properly sealing and priming concrete surfaces is essential for a successful and long-lasting paint job.
- Clean the surface
- Remove vegetation growth
- Address efflorescence
- Strip peeling paint
- Seal and prime the concrete
By following these guidelines and using high-quality products like DRYLOK®’s concrete floor paint, you can transform your rough concrete into a beautifully painted surface.
