Painting outdoor cement blocks

When it comes to painting outdoor cement blocks, the best paint is the kind that you can get from your local hardware store. Unlike other paints, it’s made specifically for concrete, so it won’t peel or flake off. You’ll also want a large paintbrush with angled bristles. This kind of brush makes it easier to work on the uneven surface of the blocks. For an even better result, use a roller rather than a paintbrush for big surfaces. You may also want to use some masking tape and plastic sheeting for protection around areas like lawns or flower beds where you don’t want any paint to go.

Maintaining outdoor cement blocks

Outdoor cement blocks need to be maintained, too. If you want them to last for a long time, seal them with an exterior sealant. You can also use a sealant on the inside of the blocks if they’re in contact with the ground or another surface that you don’t want stained.

Use a putty knife or paint scraper to remove any current paint

Cleaning off the current paint is an important step in any painting job. This will leave the surface clean and new, ready to be painted again.

Priming the Blocks

The best primer to use is acrylic latex primer. You can buy it from your hardware store or home improvement retailer. If you’re using latex paint, you don’t need a primer.

Select a bonding and filling primer

The best way to paint outdoor blocks is to first use a bonding and filling primer. This will help the paint stick better to the surface. In most cases, you should use a bonding primer followed by a filling primer.

A good bonding primer will be an acrylic or latex-based product that’s specially formulated for cement surfaces. A quality bonding primer will have elasticity, which means it’ll stretch and move when it’s wet so it doesn’t crack over time. It should also have some kind of acrylic material mixed in, which helps it adhere to the cement more easily.

A quality filling primer should be made with acrylics or silicone polymers, as these materials help seal up pores on the surface and increase adhesion to the cement as well. Again, this primer should be designed specifically for cement surfaces because certain additives may not work well with your block surfaces if they’re not capable of wielding them off without affecting the structural integrity of your blocks.

Apply a coat of primer using nap rollers

The first step to painting outdoor cement blocks is applying a coat of primer. The best way to do this is using nap rollers. This will help the paint adhere better and give you a smoother finish. You should allow ample drying time before applying a second coat of paint.

Purchase high-quality acrylic latex paint

Some companies sell outdoor paint for cement blocks, but these are not always the best option. Cement blocks need to be painted with acrylic latex paint that is specially formulated for a cement block surface. You should purchase your paint from the same company that you purchased your blocks from.

Apply a second coat of paint using a 0.5 in (1.3 cm) nap roller

If you are painting outdoor cement blocks, it is likely you will need to take a break and let the paint dry. Waiting for the first coat of paint to dry can be annoying–especially in hot weather. You can speed up the process by applying a second coat of paint with a 0.5 in (1.3 cm) nap roller. This will give the blocks more coverage and make them look much better than if you only used one coat of paint.

Allow the paint to dry for 24 hours

If you paint the blocks and they’re still wet, the paint will crack. So, allow the paint to dry for 24 hours before you handle them or put any weight on them.
