What makes concrete rendering such an effective material and how should you use it in your property or for a commercial fit out?

What Is Internal Concrete Rendering?

To begin with, it is probably worth examining exactly what concrete rendering is.

It is the same as rendering with cement – both terms are interchangeable. Either way, rendering with concrete is a very low-cost way of forming a smooth wall surface on any type of masonry.

If you have an internal wall made of besser blocks, for example, then concrete rendering can make it look much smoother and aesthetically pleasing. It can also spruce up internal walls made from standard brickwork.

What is the mix for cement render?

All that you need to render a wall with concrete is a mixture of sand, cement, water and lime. Coarse sand is perfect for the first layer of render while fine sand makes for a more attractive finish for the final, outer layer.

The lime helps prevent unwanted fissures from forming once the water has evaporated out of the mixture. So you are left with a hard, dry and smooth finished layer.

A common mix ratio used for rendering is 6 parts sand, 1 part cement and 1 part lime

It is fair to say that concrete rendering is usually used outside because it has protective qualities. It helps protect walls from excessive sunlight and rainwater. But, this does not mean that it is only good for outdoor applications.

Rooms like bathrooms and kitchens can benefit from the water protection properties of concrete rendering.

A Concrete Render Finish- Make your Wall Spectacular!

When it comes to concrete rendering, you have a whole range of creative opportunities. You don’t need to limit the look of your wall to an application of a smooth layer of cement mixture alone.

You can really make a statement by working into the render lots of different patterns while the mixture is wet. Commonly, people apply swirls with grooved instruments into their render to make attractive shapes that will set hard and remain permanently in place.

Can you Colour cement render?

You can also add dye to render which can give you a completely different look to a standard painted wall. A concrete render has more depth and personality. Concrete works very well with dyes so it doesn’t always have to be a grey and monotone material. You can also throw other additives in to add little bits of sparkle here and there too.

And of course… you can paint a rendered concrete wall. If you go down this route, then a smooth rendered finish is probably what you are after. It is possible to paint over texture render, but just make sure your render is fully dry before painting it.

The right rendering tools for the job

When using concrete render, you need the right rendering equipment or you won’t get the look you want. Whether you are a professional tradesperson working for an office fit out company or a DIY enthusiast, we have a large range of concrete rendering tools and supplies available to purchase.

Ideally, you’ll have a wire brush and a stiff broom which will help you to fully prepare the masonry you’ll be applying the new render to. It needs to be as clean as possible before you begin.

You will also need a suitable container for your mixture. Smaller walls may just need a large bucket, but for bigger ones a deep wheelbarrow and a mixing shovel might be easier.

A trowel is the tool you will need to apply your render by hand, but a large section of straight wood is also a requirement so that you can keep each layer as flat and even as possible.

In addition, you will need a metal hawk, the same sort of tool that professional plasterers use, to smooth over your render. The final item that will come in handy is a sponge trowel. This can remove excess render by moving in gentle, circular motions.

Adding the Wow Factor to Your Home

Concrete walls make a bold statement.

If your home has a mixture of different materials – woodwork, masonry and plasterboard – a concrete render feature can really add the wow factor.
