Rendering vs Plastering: Which One Does Your Somerset Home Need?

Two Different Jobs, One Common Confusion

Rendering and plastering get mixed up all the time, and it's easy to see why: both involve spreading a wet material onto a wall and finishing it smooth. We do both, and they are genuinely different jobs, with different materials, different purposes and different results.

If you are trying to work out which one your home in Somerset or Dorset actually needs, this guide will sort it out for you.

What Is Plastering?

Plastering is the process of applying a smooth, flat finish to internal walls and ceilings. It is what gives a room that clean, paint-ready surface. The most common jobs we carry out are:

• Re-skimming worn or tired walls (a thin finish coat of plaster over the existing surface)
• Replastering rooms after renovation or strip-outs, where the old plaster has failed
• Plasterboarding and skimming stud partition walls and new ceilings
• Ceiling plastering, from single bedroom ceilings to new ceilings in extensions

The finish coat is thin, fine and smooth, and designed to take paint or wallpaper. A freshly skimmed room needs time to dry properly before you decorate, so we always advise clients not to rush that stage.

What Is Rendering?

Rendering is the application of a protective and decorative coat to external walls. Where plastering is mostly about the finish on the inside, rendering has a practical job to do on the outside: it protects brickwork and blockwork from the weather, and it gives the property a finished appearance.

The main types of render we apply across Somerset and Dorset are:

• Silicone render, our specialism. Through-coloured, so it does not need painting, with a clean, modern finish.
• Sand and cement render, the traditional choice. Applied as a scratch coat and a top coat, it is solid and hard-wearing, and often used on garden walls and garages as well as houses.
• Spray cork render, a textured, spray-applied cork finish for exterior walls, available in a range of colours.

Render is built up thicker than a plaster skim, normally in two coats, with the first (scratch) coat keying into the wall and the finish coat going on top.

The Key Differences at a Glance

Which One Does Your Somerset Home Actually Need?

The honest answer: sometimes both.

Take a new extension. The new external walls need rendering to match or refresh the rest of the house, and the internal walls and ceilings need plastering ready to decorate. Those are two separate jobs running alongside each other, and because we do both, one team can handle the inside and the outside.

You need plastering if:

• Your walls or ceilings look rough, cracked or patchy
• You are renovating a room and the walls have been stripped back
• You have had new plasterboard fitted for a partition or ceiling
• You want a smooth surface before painting or wallpapering

You need rendering if:

• Your external walls are bare brick or block and need protecting
• Your existing render is cracked, blown or looking tired
• You are building an extension and need the outside finished
• You want to update the look of your property with a coloured render

If you are unsure whether your existing walls can be re-skimmed or need a full replaster, our guide to plastering over old plaster is worth a read before you call anyone.

What Our Customers Say

"Lewis has done an amazing job on rendering the front of our property. Very professional clean and tidy." — Kim King, via Google

That "clean and tidy" point comes up a lot in our reviews. Rendering and plastering are both messy by nature, so we protect the surrounding areas and leave the site in good order. On a front elevation, where your neighbours can see everything, that matters.

Kerb Appeal and Getting the Preparation Right

A well-applied render in a colour that suits the house can transform how a property looks from the street. Cracked, stained or blown render does the opposite, and it is one of the first things people notice.

The key is preparation and the right product for the wall. Silicone render over a sound, well-prepared scratch coat looks smart and stays that way with very little upkeep. Render applied over a poorly prepared surface is far more likely to crack and let water in.

Housing across Somerset and Dorset varies enormously, from Victorian terraces in Bridgwater to post-war bungalows, modern estate homes and rural stone cottages. The right render depends on the building.

Frequently Asked Questions

Is rendering harder than plastering?

They need different skills. Getting a perfectly flat skim on an internal wall or ceiling is skilled work. External rendering means working with heavier materials, planning around the weather and often working at height. Some trades specialise in one or the other; we do both, and treat each as a skilled job in its own right.

Does render need maintenance?

A little. It's worth checking now and then for cracks, damage around fixings and any build-up of algae or dirt, especially on shaded or exposed walls. Silicone render needs less looking after than a painted sand and cement finish, but no render is entirely maintenance-free.

What are the disadvantages of rendering?

The main one is that render is only as good as the preparation underneath it. Rendering over a loose or unstable surface leads to cracking and failure. Some older properties, particularly those with solid stone walls, need a breathable render system so the wall can release moisture. We'll look at your walls and explain what suits them before you commit.

Can you do the plastering and the rendering on the same job?

Yes. Because we do both, we can plaster the inside and render the outside of an extension or renovation as one project.
