How to Paint a Concrete Wall

exterior wall paintPainting a concrete wall can spruce up an area or make it blend in with the rest of the area's décor. However, there are some things to consider when painting a concrete wall. You must choose the appropriate type of concrete paint, determine if the wall is sealed from moisture and apply primer prior to painting the wall. Use these tips to paint a concrete wall.

Step 1

Choose paint for your project.

  • Select paint appropriate for your outdoor project. You will need a paint that is resistant to moisture and sun exposure. Outdoor concrete paint is available for outdoor projects. However, an oil-based paint also may work for your needs.
  • Pick a paint for your indoor paint project. Basement concrete paint is available in many paint and home improvement stores, however you also can use an interior acrylic paint for the project.

Step 2pressure washer

Clean the concrete wall. For exterior projects, use a power washer to rid the wall of all dirt and dust. If your project is indoors, scrub the wall with soapy water and a scrub brush instead of using a power washer.

Step 3

Repair any cracks or blemishes in your wall with concrete patch. Follow the directions to mix up the concrete patch mixture. Fill holes and use a trowel to smooth the patch to match the surface of the wall.

Step 4

Check the wall for moisture. Paint applied to a wall that is not properly sealed will not adhere properly.

  • Tape plastic sheeting to the wall. Attempt to get the sheeting as air-tight as possible.
  • Check the plastic after 24 hours. If moisture appears within the plastic, you will need to seal the wall. If no moisture is present, the wall is already sealed

Step 5

Seal the concrete wall. Roll on 1 coat of concrete sealer and allow it to dry overnight. Concrete sealer is available at most hardware or home improvement stores.

Step 6

Apply 1 coat of concrete primer. You can use rollers or brushes to apply the paint. Ensure the primer is applied evenly, whichever technique you use. Let it dry for 24 hours. If you can see the wall through the primer, apply 1 more coat.

Step 7kids and pet

Paint your wall with concrete paint. Paint should be applied in at least 3 thin layers. The paint may be sprayed on, rolled on or painted on with a brush. The paint should not be streaky or show brush strokes. Allow to dry for 24 hours.

Step 8

Roll on concrete paint sealer. Cover with 2 coats, allowing it to dry between coats. Paint sealer helps the paint to adhere to the wall and last longer

Tips

  • Keep pets and small children away from your painting project. The fumes can be harmful to them. Additionally, they may rub up against your wall while you are painting it.
  • Wear appropriate safety equipment, such as gloves and goggles.
  • Make sure the area in which you are painting is well-ventilated. Concrete paint, primer and sealer have strong odors.
  • Wear old clothes to paint your concrete wall. Paint used for this project is likely to stain your clothes.

Enamel or acrylic paint?

Plascon Multi Surface PrimerThis topic has bothered me for many years and I have never managed to find a helpful answer. If I’m coating a previously painted surface, how do I know what type of paint was used. I assume it is important to know because water-based and oil-based paints are very different.

1.    Is it possible to ‘prime’ an existing oil-based paint with universal undercoat and apply water-based paint over     this? I prefer to use water-based paints because cleaning the brushes and rollers after use is so much easier.
2.    Is there an advantage to using enamel over water-based paints?

A Toni Stella the Paint Fella replies: 

Determining whether the surface was painted with a acrylic or oil-based paint is very important.

Testing for an oil base:
•    Soak a cotton wool ball or very soft cloth in methylated spirits, alcohol or lacquer thinners and rub it back and forth over the area.
•    If the paint rubs off (dissolves) and you see the other colour below, you know it’s a acrylic product.
•    If no paint is removed, it’s an oil-based paint.multi surface primer
Oil-based enamels can sometimes be painted directly over acrylic (however, it is not acceptable industry practice). Special preparation is needed to cover oil-based paint with acrylic.

Covering oil-based enamels with acrylic:
•    Surfaces previously painted with oil-based enamels must be abraded with a Scotch-Brite pad and a solution of sugar and soap.
•    Rinse with clean running water and repeat until a matt surface is achieved.
•    Apply a coat of Plascon Multi-Surface Primer and allow it to dry for four hours at 23˚C.
•    Apply the final coat of acrylic paint.
•    Your brushes and tools can be cleaned with water.

How to paint palisade fencing

how to paint a palisade fence
When you go to the expense of installing palisade fencing around your home, you want it to not only provide security but look good too. Because palisade fencing is generally made of steel - it requires regular maintenance to keep it in tip-top condition. Here are some tips from Plascon Metalcare on painting and maintaining a palisade fence.

STEP 1:

Use Plascon RemovALL All Purpose Paint Remover to remove all flaking and peeling paint.This product is a brushable,water-based paint remover that is biodegradable, user-friendly and environmentally safe. It is extremely effective in removing the toughest industrial coatings, like epoxies and urethanes, from metal, concrete, wood, masonry, and brick. Any rust can be treated by using Polycell End Rust to create an impervious film on the metal. Please note that a rust remover/converter should not be used on galvanised iron.metalcare degreaser

GOOD TO KNOW

On walls with palisade panels, place newspaper under the fencing to prevent drips and runs.

STEP 2:

Apply Plascon Metalcare Waterbased Degreaser to the fence and rinse well with clean water. Allow to dry.
Plascon Metalcare Waterbased Degreaser is a non-abrasive and fully biodegradable water- and citrus-based cleaner that removes oil, grease and grime from surfaces.

STEP 3:
Use a paint brush to apply Plascon Metalcare Waterbased Primer for an extremely high protective barrier. The unique red oxide formulation gives great protection against metal corrosion and degradation.

GOOD TO KNOW
Start at the top of the fencing and work your way down. That way you take care of any drips or runs.

STEP 4:steel palisade fence

Finish your fence off with 2 coats of Plascon Waterbased Enamel for a durable long-lasting and chalk-resistant finish.
Plascon Waterbased Enamel is available in a wide range of tinted colours. Regular maintenance will ensure the lifespan of your palisade fencing and it's important to repair paint chips as quickly as possible to prevent the formation of rust. Keep the base of your palisade fencing clear of obstacles that may prevent the normal flow of water. Puddles around the base of the fence will eventually cause paint to peel and rust to set in.

Where rust stops occur - take the necessary steps as soon as possible

When to use a spray spray paintinggun?

When should I use a normal paintbrush for painting, and when should I consider using a spray gun? Why is it better to paint a palisade fence with a brush than with a spray gun?
Brett van Rooyen, Centurion

Our technical consultant, replies:

When using a spray gun there is a thing called ‘overspray’, so when painting thin materials like palisade fencing, the amount of paint that you lose is great. But, on the other hand, the finish will be of higher quality; a lot smoother and with no brush marks.

When using a paintbrush on palisade fencing the coat is a lot thicker than when using a spray gun. My advice is that if going for the spray gun option, choose a spray gun with an adjustable spray pattern. Also, use a cardboard box behind the fence that you are spraying as this will act as a deflector and will allow some of the overspray to coat the other side of the fence. The cardboard needs to be placed about 5cm behind the fence.

How to Paint a Fence Part 1

painted boundary fenceBesides its cosmetic effects, paint provides outdoor structures with protection against the elements. Fences, in particular, need a protective coat of paint every 2 to 3 years. They're usually built away from other structures and trees, which could otherwise shield them from the elements. Paint helps iron and metal constructions resist rust and corrosion. It also fortifies wood against the effects of wind, rain, snow and extreme temperatures. Fence-painting is a time-consuming, but important, undertaking. By doing it at suggested intervals, you can strengthen the fence, reducing the likelihood of it needing to be replaced. If you want to learn how to paint a fence, follow these steps.

Prep the area around the fence. Preparation is a critical phase of fence-painting. You want to protect the vegetation along the fence line while readying the surface for painting. This is a time-consuming process, but it makes the job easier.

  • Mow and edge the grass along the fence line. Trim back bushes and shrubs that abut the fence. Use a leaf blower to blow dirt and grass clippings away from the fence line.
  • Spread a drop cloth or plastic sheeting under the section of fence you'll be painting. Keep it in place throughout the project to collect residue from prep work and protect against spills.
  • If the fence was previously treated, scrape off loose or flaking paint.
  • Pressure-wash or sand a new, untreated wood fence. It's best to sand a fence that was painted before. This helps the paint adhere to the wood. If necessary, use a scrub brush and a 1-to-1 mixture of bleach and water to eradicate mold on the fence. Let the surface dry.
  • If you're painting iron or metal fencing, use a steel brush to remove rust and then sand the surface with medium-grit sandpaper.
  • After sanding, wipe off residue with a clean rag.
  • Seal and tape off parts of the fence you don't want to paint, like ornaments, gate latches and handles and other hardware.

Pick the right paint for your job. Make sure you use an outdoor paint on your fence. These are specially treated to withstand the effects of weather and come in a variety of types.

  • Acrylics: Acrylic paint is durable, providing an excellent layer of protection for your fence, but you might have to apply a primer to an untreated surface before you can paint.
  • Acrylic stains: Stains bring out the natural beauty of the wood and usually don't require the primer coat that paints do. They also are easier to re-coat and require minimal surface prep.
  • Oil-based outdoor paint: Oil-based paints may require multiple coats and may not protect as well as acrylics, but they do provide a superior-looking finish.
  • Enamels: Enamel paint is ideal for iron fencing and gates. Usually, you'll need to treat the surface with a rust-inhibiting primer.
  • Automotive epoxy paint: The benefits of automotive epoxy are, it's a 1-step process and is very durable. You will have to mix in a hardener with this paint, which does force you to get the job done within about 6 hours.
