The Best Plaster For You

Repairing plaster walls can be tricky if you don’t know the right plaster to buy to repair a damaged plaster wall. Different types of plaster have varying plastering costs, appearance, and durability.


Commonly known as drywall or Gypock, it is the most preferred by builders simply because it is easy to install, moisture and fire-resistant, and has sound insulation. They make an excellent lining for walls and partitions.

Wet Plaster

It provides more soundproofing and fire resistance than drywall mud. It is a mix of several elements such as lime, cement, and gypsum plaster, making for a smooth and durable wall surface. Every coat of plaster needs a skilled application and may take a while to dry completely.

Ornamental Plaster

Used for sculpting mouldings, cornices, and other features and can be directly applied on walls and ceilings.

Cement Plaster

It has a rough texture and comes in the colour grey. It is robust and durable and made of sand and cement but shrinks and cracks with time.

Gypsum Plaster

Gives smooth plaster walls ready for paint – Gypsum plaster walls are the simplest to install and repair plaster walls. It is also mould and mildew resistant.

However, even if you are relying on a plasterer to fix the loose plaster in your old house, you should be aware of the different steps to repair plaster walls:

Prepare The Repair Area

Say you are starting with repairing your bedroom walls. The first step is to prepare the room by covering the floor with a painter’s drop cloth and paper tape, and the taped area protects the floor from wet plaster or joint compound.

You should also seal the room with plastic sheets to prevent sand dust – like a dust mask – from fine-grit sandpaper used on plaster walls to sand lightly after the final layer has dried up, from flying and blocking vents. Preparing the room makes cleaning up easier.

Reattach Loose Plaster Compound

The plaster can get loose if it becomes too old and fall off. You can get the plaster reattached using drywall screws as the first step. If you directly apply multiple layers of plaster to the cracks, it will quickly become loose material.

Drill Holes Near Cracks On Plaster Walls

Drilling holes on two sides of the cracks prevents structural issues from arriving and for your plaster to stick well with the wall studs. Ensure a minimum distance of 3 inches between the holes for maximum effect.

Apply Adhesive Compounds Into The Plaster Holes

It would be best to vacuum the holes, apply conditioner and then inject the adhesive into the holes. You can remove the excess adhesive with a utility knife or a sponge.

Fill The Cracks

Mix the joint compound or patching plaster with water with the putty knife. Use the putty knife to fill the cracks with the plaster and cover with paper tape.

Sand The Plaster Down

Before applying paint over the solid plaster, it is essential to sand the plaster down. Use 120 to 150 fine-grit sandpaper to smooth the surface of the plaster. Once the surface is smooth and the cracks filled with patching plaster or joint compound, it is ready for paint.
