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.

Electrified palisade fences

electrified palisadeAn electrified palisade fence is a steel or aluminium palisade fence used as a defensive barrier for the protection of property, particularly in isolated regions.

Typical construction

Electrified palisade fences are usually made from painted mild steel, galvanized steel, stainless steel or aluminium. Typically the fences are 2.4 metres (7 ft 10 in). All electric fences have energisers which send high voltage electric pulses through the palisade, usually at a frequency of 1 Hertz (one pulse per second).

Uses

The two most common uses of electrified palisade fencing is in protecting isolated property and in the defence of high security facilities. Palisade electric fences are used in most countries, particularly where there is little vegetation to short circuit the fence or where the costs of security personnel is high in relation to automated security equipment.

Isolated property is vulneelectrified fencingrable in that it is difficult or time consuming to send security personnel to respond and so must be self sufficient with an automated security system. The electric pulse is a strong deterrent for criminals, while the palisade fence is mechanically stronger than a typical steel cable electric fence being able to withstand impact from wildlife, small falling trees and wildfires.

South Africa

Due to the high levels of crime in South Africa, it is common for residential houses to have perimeter defences. The City of Johannesburg promotes the use of palisade fencing over opaque, usually brick, walls as criminals cannot hide as easily behind the fence. In the City of Johannesburg manual on safety one can read about best practices and maintenance of palisade fencing, such as not growing vegetation in front of palisades as this allows criminals to make an unseen breach.
