Top 10 great facts about plastering
Plaster has been around since ancient times and has many uses.

Fact 1: It may contain marble or olive

There are a number of varieties of plaster available.

At its most basic, plaster is a mixture of lime or gypsum, sand or cement, and water.

Other variations include:

  • Slaked lime
  • Venetian (featuring pigment and marble dust)
  • Tadelakt (featuring lime plaster and black soap made from olives)

Fact 2: It was replaced by drywall

Plaster was the wall material of choice until the invention of commercial drywall.

Plaster “typically lasts longer and is more beautiful” than standard drywall. It is also fire-resistant and good at blocking noise. On the other hand, it is trickier to install and expensive to repair if damaged.

Fact 4: It is environmentally friendly

Plaster is an environmentally friendly material – which cannot be said for paint and other alternatives for covering walls.

“It is breathable, free of chemicals and VOC. If you’re concerned about toxins and eco-friendly finishes, natural plasters are a good option.”

Fact 5: It can be waterproof

Tadelakt, the Moroccan plaster, is made from lime plaster and a black soap made from olives.

Combining these two ingredients creates a chemical reaction that creates a waterproof, moldproof and mildew-proof finish, ensuring it is a durable choice for the kitchen or bathroom.

“Tadelakt is the Rolls-Royce of lime plaster finishes,” says artisan Orit Yanai. “It’s generally much more expensive than other types of plaster, so use tadelakt in wet areas, and another type everywhere else.”

Fact 6: It needs layering

Most plasters are labour-intensive to install.

Plaster generally needs three coats and corners are tricky to trowel. Often workers need to move quickly to avoid cold joints, that are spots of weaknesses in the plaster.

Fact 7: It helps to maintain heat and air

When applied correctly plasters plug gaps and cracks, and walls and ceilings become airtight.

This subsequently keeps air inside rooms and buildings.

Fact 8: Damp walls can (but should not always) be plastered

This depends on the type of damp specifically.

In the case of rising or penetrating damp, plastering should be avoided until the issue is fixed.

If the wall in question has recently had a damp proof course that has worked well, plastering will be fine.

Fact 9: The appropriate plaster mixer tool depends on a few factors

Creating a smooth, consistent mix is essential to any plastering success.

The role of the electric mixer is to speed up the job and create a mix that is easy to apply onto different backgrounds.

You can choose between a forced action mixer or a mixing paddle, depending on the volume needed, the number of times that the mixer will be used and the versatility needed.
