Types of Rendering for Houses

types of rendering for houses

There’s many types of rendering for houses, and your choice will need to take your property’s age, existing substrate, and desired effect into consideration.

Rendering, effectively, the finished ‘look’ of your outside walls, is made up of a binding agent, structural filler, water, fibre and some chemical additives, such as silicone, polymer and acrylic.

Rendering: What are the Options?

The most common render finish for wall is lime render. Comprised of lime, it’s both breathable and flexible, so suits buildings that move a lot, timber framed buildings, and older properties as well.

It’s traditionally applied to walls made of low quality stone, or where walls are exposed to wind and rain. Lime render acts as a sponge, however, and does absorb water, so can easily grow algae and mould.

Sand and cement renders are cheap to apply and quick, so are an increasingly popular option for homes with less vulnerability to movement and weather.

However, these two can absorb a great deal of water and so deteriorate over time.

Clay renders are the ‘original’ wall finish and can be locally and ethically sourced easily, but are now considered a dated option. Clay degrades over time, particularly when it takes on water, and so needs lots of cleaning and, eventually, replacement.

Pebble dash mortar was particularly popular toward the end of the last century and is a wet mortar with pebbles, chippings, gravel and shale applied for decorative effect.

Protect Your Property for the Long-Term

Regardless of which render you choose, it’s important to protect the finish so that you don’t have to spend a great deal of time on cleaning, upkeep and maintenance.

Exterior wall insulation is a chemical spray applied with industrial equipment. It sits on the wall as a protective barrier that stops water, dirt and dust from entering the pores of the material, allowing only the minimum amount of air to pass through.

The spray chemically penetrates into the surface of the wall’s material, up to 17mm, to ensure a thorough thermal barrier is installed.

Insulating your external walls against the elements is crucial for inclement weather, shade and for properties in sea-salt-penetrated air.

It keeps out damp and the cold, but also effectively makes your exterior walls wipe-clean – as dirt and nasties in the air can no longer grip into the material’s pores, and will just wash away with water. For most of us, the rain will take care of it!

Professional Products, Professional Service

Exterior wall insulation can last for up to 20 years, but it’s imperative to have it sprayed on by a certified expert technician, to ensure it lives up to its full potential.

If, like most homeowners, you don’t own a new-build property, you can still have the exterior wall insulation applied onto your render after cleaning. A technician will ensure that your walls are power-washed to an industrial standard, treated for algae, and that all cracks and vulnerable areas are repaired.

Windows, doors, guttering and any areas not to be treated are covered completely, and a priming coat is applied before the insulation is sprayed on. Once applied, it’s effective immediately, and you’ll notice the benefits right away.

Your rendering will remain neat and tidy, and last up to 20 years without a second application.
