Can I paint over cement render?

If you are looking for a way to give your rendered walls a new fresh look, there’s nothing as quick and effective as a fresh coat of paint. Painting your cement rendering can be done with a large variety of paint types, but you must choose the right one for your preferences. The typical technique for wall rendering in Brisbane is usually made up of a combination of sand, cement, and polymer. You need to choose the best paint because it will be able to stick to the rendered surface. When it comes to a fresh coat on rendered walls, it’s not as simple as grabbing a paint stirrer and any old bucket of paint before slathering it on the walls.

Can you paint over render?

Yes, you can paint over render. But we strongly suggest that you don’t attempt to do this yourself. That’s because it needs to be done correctly to make sure that it stays looking good for years to come, and you could be putting yourself in harm’s way.

What types of paint can be used on rendered walls?

Before choosing the right paint for your render, you need to get familiar with the type of render that will be worked on. The most suitable colour for rendered walls will always be epoxy, acrylic or vinyl paint. Proper painting of a rendered wall requires the use of vinyl paints and extensive prep work. That’s because the paints are very quick-drying, and they won’t fade in Brisbane’s occasional harsh sunlight. They are also designed to protect your walls and render against weathering and water damage because they won’t allow moisture to penetrate through them into the rendered walls underneath. Vinyl paint is also perfect because it has a thicker consistency that makes applying evenly onto a rendered wall easier. The formula is also excellent and does not hold onto brush or roller marks.

These paints are perfect for rendering because they are two-component paint formulas that come premixed in a cartridge. They can come in a wide range of colours and sheens, including matt, satin and gloss, with good covering properties that can be thinned with white spirit for trouble-free application. Vinyl paints are the better choice when painting rendered walls with adequately prepared renders, but if your render needs much more work, it’s best to opt for epoxy paint.

Take it from us as a trained tradie in Brisbane. To achieve a smooth exterior finish, your best option is a well-known brand like Dulux and purchase a weather-resistant paint product.

How to prepare your render for painting?

1.    Clean the surface

A good, long-lasting paint job requires that the rendered surface is prepared correctly. A professional will take the time to clean away any flaking or loose render from the wall’s surface with a stiff brush and water solution. As part of your regular maintenance when cleaning the exterior of your home, you can also ask a professional to recommend the right cleaning products for several types of wall surfaces. Lime based rendering, for example, requires strong alkaline detergents. Give your walls a rinse with clean water and brush off any fallout whenever you get the chance. If areas of concern may need repair, your rendering expert will mix a patching compound and apply it to fill in the damage.

2.    Remove residue and protect hardware

After cleaning, the professional will then vacuum away any debris or render fallout. The expert may ask to remove all door and window hardware for the paint job or cover these areas with protective materials. They may use masking tape for places that might get messy. They’ll also deal with any staining on your render by treating it before applying any paint because stains can repel paints and stop them from sticking properly to the surface.

How much does painting over render cost?

The cost to paint over your render can change based on which part of Australia you are in. The cost of painting a rendered house in the Brisbane area alone also doesn’t have a standard or set figure because it can change based on different things from one job or property to another. Things like the size of the job, the structural quality of your render and the type of paint can have some weight in the potential for increases and decreases in the overall cost. When it comes to the cost of materials, painting over render is similar to painting other wall surfaces, and by this logic, it should cost roughly the same. You will have to factor in the cost of how much paint you’ll need to cover all the square metres that make up the surface of your property. Typically, a low set, usually sized 3-bedroom house in Brisbane would cost anything between $4,000 and $6,000 for a primary paint over render job. This price is just a guide and is dependent on the condition of the render, the preparation required, and all the number of coats needed. There is also a difference between cosmetic and protective paint coating over render, and we provide both.
