How to Paint an Outdoor Concrete Fence

Concrete fences are typically grey and dull, making them boring and sometimes uoutdoor concrete fencensightly. To remedy this, you can paint a concrete fence, giving it colour and make it look new. Painting an outdoor concrete fence can be done alone or you can ask a family member or friend to help you. It is important to remember to use only primer, paint and sealer that is made for concrete and block. Otherwise, the paints will not bond and will flake off the fence.

Things You'll Need

•    Trisodium phosphate (TSP)
•    Bucket
•    Rubber gloves
•    Scrub brush
•    Concrete patch
•    Trowel
•    Concrete primer
•    Pump sprayer
•    Paint thinner
•    Concrete paint
•    Concrete sealer
•    Paintbrush

Mix together three parts water with one part trisodium phosphate (TSP) in a bucket.

holesPut on rubber gloves and thoroughly scrub the concrete fence with a scrub brush, cleaning away any dirt and grime. Rinse the concrete fence with plain water and allow to air dry.

Fill any holes or cracks in the fence with concrete patch using a trowel to apply the patch and to smooth it flush with the surface. Let the patch dry according to the manufacturer's instructions.

Pour concrete primer into a pump sprayer and apply a coat of primer to the fence. Let the primer dry completely before continuing on to the paint.

Rinse the pump sprayer with mineral spirits, then water and let air dry. Add concrete paint to the sprayer and spray on the first coat of paint. Let the first coat dry between 3 and 4 hours, then apply a second coat of paint.

Brush a coat of concrete sealer onto the fence using a paintbrush once the second coat of paint has dried.

Common Problems with Painting Concrete Walls

Painting concrete walls can result in a few problems if the concrete wall has not cured. If the concrete cannot adequately cure before it is painted, the paint will trap the excess moisture within the concrete and the paint can peel some of the cement as it peels itself. Painting the concrete wall can also cause the plaster to not receive the water cure that it needs.

common problems

Cracks in the Wall

Before priming the wall, cracks in the concrete should be filled with a material that can withstand weather effects. If the wall plaster has a texture, then sealant should be of a matching texture. If it is not, bands of smooth surface can be seen through every coat of paint in a different contrast.

Coverage

If primer and paint is applied, it needs to be applied across the whole surface in order to have the best results. Once the primer has been applied and allowed to cure, the finish coat needs to be laid on in several thick coats. If not, the uniform color will not be attained and you will not achieve the look that is desired. Some projects do not have primer applied before the paint. Other projects may have had paint thinned so much that the coat is not even effective. This makes the wall look like it did not receive adequate coating.

Primer

In order to get the bond desired, the right primer will need to be applied to new concrete walls. This will prevent paint delamination also. There are some paints and primers in particular that needwall painting to be used together. Although cement plaster and concrete should have a coat of primer before the paint is applied, painters do not always prime concrete and plaster.

Delamination

Delamination is the process of paint peeling from a new concrete surface or cement plaster. Paint will delaminate from concrete just as it does from wood and metal. This is why the concrete wall needs to be well prepared and all application procedures need to be followed. Moisture from rain or from the concrete not curing will release from the concrete and cause cleaving.

Over Brushing the Paint

If a painter applies paint to the brown coat on cement plaster, the paint will serve as a bond breaker causing delamination. Plaster behind a coat of paint will turn soft if paint is not allowed to cure. Paint will keep the water from evaporating properly. Concrete walls need to be prepped and primed. Paint needs to be thick and not diluted.

What Paints Can You Use on Concrete?

paints can use concrete

Though you can use any paint onplaster primer concrete, some kinds prove better suited for certain types of concrete surfaces. Learn which finishes will prove most resilient on concrete floors, statues and walls, or finish failure will prove possible. Learn how to condition the concrete for adhesion, or no type of paint will prove durable in the long run.

Concrete Walls

  • Ordinary latex paint is well-suited for interior concrete walls. Use an eggshell or satin latex paint on concrete walls that aren't exposed to much duress. For concrete walls within weight rooms, work rooms and kids' play rooms, choose a semi-gloss latex paint that will resist stains. If you plan to paint exterior concrete walls and fences, use an exterior acrylic paint that will hold up to ultraviolet light and harsh weather conditions.

Considerations

  • No type of paint will adhere to improperly-prepared concrete. Prime vertical concrete surfaces, or the paint will eventually chip. Use a latex primer on interior walls; use an acrylic primer on exterior walls. Smooth horizontal concrete surfaces do not require a primer; however, they will reject paint unless they are treated with an acid etch.

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.

Best Kind of Paint to Use on Concrete

bestconcretepaint

As mediums for painting go, concrete is not one of the better ones. It transfers moisture from the ground or surrounding dirt, and it breathes and sucks up paint like a kid with a soda. Concrete requires special paint that contains binders that contract and expand right along with the surface.

Do not use oil-based or acrylic house paints on concrete or you’ll just have to paint it all over again, because acrylic paints peel, crack and just can’t take the abuse that concrete patios, sidewalks and driveways undergo.
