Grasping the Concept of Plaster

Plaster is a mixture comprising lime, cement, sand and water that has been utilised for centuries to create long-lasting surfaces on walls and ceilings. It serves as a foundation for paint and wallpaper while providing a pleasing finish. Before applying plaster, it’s vital to prepare the surfaces by removing any paint, dirt or debris. If needed, address any cracks or holes by patching them with plaster before commencing.

Varieties of Plaster

Numerous plaster types exist that you can utilise depending on your requirements and preferences. The most used varieties include:


  1. a) Gypsum plaster: 

Also referred to as plaster of Paris, gypsum plaster is straightforward in mixing and application.


  1. b) Lime plaster: 

What is lime plaster? Lime plaster has been used for many centuries as a traditional material. It offers breathability and flexibility, making it suitable for houses or buildings with moisture issues.


  1. c) Cement plaster:

Cement plaster is a mixture of cement and sand, creating a lasting and water finish. It is commonly applied to walls and surfaces.


Tools and Materials

To begin your plastering project, you will need tools and materials. These include:

a) Plastering trowel: 

A metal tool with a handle is used to apply and smoothen the plaster.

b) Bucket and mixing paddle: 

These are used to mix the plaster with water until it reaches a smooth consistency.

c) Hawk: 

A flat square board with a handle on the underside that holds the plaster while working on it.

d) Jointing knife: 

A blade designed for scraping off the plaster and creating clean edges.

e) Sandpaper: 

An essential tool for sanding down any patches or imperfections in the dried plaster.

f) Drop cloths or plastic sheets: 

These are necessary to protect the surrounding area from splatters or spills while working with plaster.

g) Primer for plaster: 

A treatment used on surfaces to enhance the adhesion of plaster.

h) Paint and wallpaper: 

Choose the desired finish to be applied after the plaster has dried and been sanded.

Applying Plaster

Now that you have gathered all the tools and materials, it’s time to begin applying the plaster. Start by following the manufacturers’ instructions to mix the plaster powder with water. Stir thoroughly until you achieve a creamy consistency. Using a hawk and trowel, scoop some plaster onto the trowel. Apply it to the wall or ceiling using small strokes and work from top to bottom, ensuring an even application. Once you have covered the surface, use the trowel to smoothen out any ridges or bumps.

Polishing and Finishing

After applying a layer of plaster, allow it ample time to dry completely before proceeding. The drying duration can vary depending on weather conditions and the type of plaster used; it may take up to a day. Once fully dry, you can begin polishing by dampening the surface using a sponge or spray bottle. Employ light motions while using the sponge to smoothen out any imperfections in the plaster. Allow drying time before applying layers if needed.

To achieve the desired smoothness, repeat the polishing process between each layer.


Sanding and Priming

Once the final layer of plaster has dried and you’re satisfied with its smoothness, it’s time to sand the surface. Use sandpaper to get rid of any patches or uneven areas. Be cautious not to sand too aggressively and damage the plaster. Once you have a smooth surface, wipe away dust using a damp cloth. Before applying paint or wallpaper, it’s crucial to apply a plaster primer. This will create an adhesive surface.
