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.

Precast Concrete Wall Repairs

concrete crackIf your Concrete Wall has developed hairline cracks or small holes, you can and should repair it immediately to avoid the damage growing and causing a weak spot in your security.

Firstly, clean the area around the cracks or small holes using coarse sandpaper. Make sure you remove all dirt and dust from the wall.

Next, you need to soak the area around the small holes or cracks and keep wet for a few hours. Doing this will prevent the dry concrete from absorbing the water from the cement grout once you have applied it.

Mix the cement and water in a metal bucket to form a thick. Smooth grout. You need to stir continuously to prevent any lumps from forming.

Next you need to fill the hairline crack with the cement, using a trowel. You can use the trowel handle tip to pack the grout firmly and fully into the holes. Always press and spread the grout into the crack and over the edges, then smooth the grout down with the flat side of your trowel.

Cover the repaired cracks and holes with large plastic sheet, which you must tape with duct tape.

For 5 days, you need to dampen the repaired cracks or holes with a little water, then cover again. Do this every single day for the 5 days.

You can then apply a silane-based sealant to the repairs and a few cms all around the cracks or holes, to ensure a good, stable seal. Use a synthetic bristle paint brush for this.

Honeycomb in ConcreteMake sure you check your walls regularly for any sign or cracks or holes, then repair immediately to prevent any cracks extending or widening, and holes enlarging.

Security is very important today, and in no way must you allow any cracks or holes to stay unattended, thus giving would-be intruders an easy way into your property.

We, at Country Wide Walling, seriously recommend that you get the professionals to do any mending or replacing on your precast concrete walls, as this will ensure that the repairs will be done professionally and last a very long time.

Setting Boundaries

surveyingIt is surprising that there are many people who do not know where the precise edges of their property boundaries are.

Sometimes boundaries are lost because the property has changed hands over the years.  You cannot just assume that the boundary is consistent with the existing fences that are surrounding it.

The basis of many disputes between neighbours is the exact location of the boundary of a property, or the perceived belief that a neighbour is encroaching on your property, either knowingly, or unknowingly.

In general the boundary fence belongs to both owners, and if necessary can be checked by a surveyor.

If a new fence needs to be erected, or an old one needs to be repaired, the cost should be split equally between the two neighbours.  Both property owners have a responsibility to keep the fence in good condition, and neither neighbour is allowed to remove the fence without the permission of the other neighbour.

There are some basic rules which apply to boundary fences.  

If you wish to remove or replace an existing wall or fence, it is very important to first consult with the neighbour.  Never attach anything to a fence without consulting with the neighbour.

The same applies if you wish to raise the fence/wall for more security, e.g. attaching lattice to the fencing.

angry neighbourAlways talk to your neighbour about anything pertaining the boundary fence/wall.  Ask for any agreement to be given in writing.

Should your neighbour be difficult and refuse to do their share, it is always best to first seek legal advice.
Talking to your neighbour is the best way, and will prevent any hostilities and unpleasantness.

As we have said before:   Good fences make for good neighbours.

Should you wish to erect a new wall or fence, or raise and existing one, please feel free to contact us and speak to one of our highly trained consultants.  They will be able to advise you on what would be your best option.

Concrete Palisade Fencing for Security

stormWith our harsh climate and high crime rate in South Africa, Concrete Palisade Fencing has become the material of choice, as it can not only withstand harsh weather and wear and tear, it also has the benefit of being see-through, meaning that nobody can sneak up to your property unseen.

Another benefit is that Concrete Palisades have no scrap value, unlike metal, which can be stolen and sold as scrap.

Concrete Palisade fencing marks the boundaries of your property in a neat and aesthetically pleasing way, at the same time screening your home and garden, thus providing security and maintaining your privacy.

little kids running street 21063594We all know that small children and pets love to wander, and we need to keep them safe, and prevent them from wandering out of your yard into the streets, and into danger from traffic.

We would all love to have high, solid walls around our properties to ensure our privacy, but the drawback is that it also provides privacy to intruders, as, once they have found a way in, they cannot be seen from the outside by anyone passing by, or even security on patrol.

Because our products use integral colour, your palisade fence will stay looking beautiful for years to come. Permanent colour can be added during the manufacturing process, which means your palisade will remain beautiful for many years.

At Country Wide Walling we take pride in our workmanship, and endeavour to exceed our clients expectations.
