Plastering Sand

An essential element, plastering sand is combined with cement and water at certain ratios to achieve proper plastering material. When purchasing plastering sand you can either find it as its own separate material as shown below or pre-blended with cement.


Plastering Sand


If you purchase sand which is not already pre-blended, on-site, you’ll add your materials together to create the plaster. For proper adhesion, you’ll need to cure your walls before and after plastering. Use a wet covering or sprinkling method to ensure you have the proper conditions for using plastering sand. 

Plastering sand is a versatile product and can be used on both exterior and interior walls. However, it cannot be applied on smooth surfaces. You’ll need to rough up your walls before application to ensure the project holds. 

Note as well that plastering sand can be prone to cracking or shrinking from the drying and ageing process, so this may require further attention in the future for repair.

 

Gypsum Plaster

Made up out of gypsum, this plaster is used to build up the finish of your walls to a strong and durable state. You’ll get this plaster in a dry format that, when mixed with water, will set and harden. You won’t need to add sand when using gypsum, making the preparation a little simpler than other materials. 

Since this type of plaster tends to draw moisture, it’s best used only on some interior walls and ceilings. It can be applied to both smooth and rough surfaces.


Avoid using gypsum in bathrooms or kitchens as the higher levels of moisture can cause the gypsum to absorb water and develop issues. 

Gypsum plaster can achieve a fine finish and is often used as a topcoat in plastering projects. It’s less prone to cracking, making it a great choice for your walls’ longevity.

 

Bonding Plaster

This is a versatile plaster that can be used to create a great first coat, called undercoat, for your project. Also called a scratch coat, bonding is an essential foundation for finishing plaster. It can be applied to concrete or tiling, and you won’t need to rough up these surfaces for bonding to adhere.



Bonding is also used on new walls or those that need patching. It allows upper coats to grip once it is scratched with a nail to create a rough surface for adhesion. It can be used both on the interior and the exterior of your home.   


Summary

Whether it’s a new wall or a repair, using plaster is a tried and true method of home improvement. All it takes is some skill and the knowledge of what materials you need. 

After reading your article, you should know what kind of plaster your job needs. Using this will ensure the best results. Now it's time to hire a local plasterer and get your project started!
