Preventing Plastering Mishaps: Common Errors to Avoid


Plastering is a crucial part of any construction or renovation project. It is a skilled trade that requires proper training, experience, and attention to detail. Even while it might appear simple, there are a lot of typical mistakes that can result in plastering disasters. 

These mishaps can be costly and time-consuming to fix, so it’s important to take preventative measures to avoid them. 

The sections below will discuss some common errors to avoid when plastering.

Error #1: Poor Surface Preparation

One of the most common errors in plastering is poor surface preparation. The area to be plastered must be dry, clean, and free of dust and debris prior to the application. 

Nothing doing this step can lead to the plaster not adhering properly, resulting in cracks and other imperfections. Any loose or flaking paint or plaster should be removed, and any holes or gaps should be filled with an appropriate filler.

Error #2: Incorrect Mixing Proportions

Another common error in plastering is incorrect mixing proportions. The manufacturer’s directions for mixing plaster should be followed, with the correct amount of water added to achieve the desired consistency. 

If too much water is added, the plaster will be too runny and may not adhere properly. Conversely, if too little water is added, the plaster will be too thick and difficult to spread evenly.

Error #3: Inadequate Coverage

Inadequate coverage is another common error in plastering. When applying plaster, it’s important to ensure that the entire surface is covered evenly. 

Failure to do so can lead to uneven drying, which can result in cracks and other imperfections. If the plaster is not applied evenly, it may be difficult to achieve a smooth finish.

Error #4: Insufficient Drying Time

Proper drying time is essential to achieving a smooth, even finish. Rushing the drying process can lead to cracks and other imperfections. Generally, plaster should be left to dry for at least 24 hours before any additional work is done. 

It’s important to ensure that the room is well-ventilated during the drying process to prevent moisture buildup.

Error #5: Poor Tool Handling

Poor tool handling is another common error in plastering. You must use the right tools for the job and to use them correctly. For example, a trowel should be used to spread the plaster evenly, while a float should be used to achieve a smooth finish. 

It’s important to clean tools thoroughly after use to prevent the buildup of plaster, which can affect their performance over time.

Doing a Plastering Job the Right Way

1. Deal with Existing Plaster Damage

If you’re working on a renovation project that involves existing plaster, it’s important to address any damage before applying new plaster. Common types of damage include cracks, holes, and dampness. 

These issues can be caused by various factors, including age, water damage, and structural issues. It’s important to identify the cause of the damage and address it before attempting to plaster over it.

2. Choose the Right Plastering Material

Choosing the right plastering material is crucial to achieving a successful outcome. There are many types available, each with its distinct properties and uses.


For example, lime plaster is ideal for historic buildings, while gypsum plaster is better suited for modern construction. It’s important to choose a plaster that is appropriate for your specific project and to follow the manufacturer’s instructions for mixing and application.

3. Get Professional Plastering Services

While DIY plastering can be a cost-effective option, there are many benefits to getting a professional plasterer. Professional plasterers have the experience and expertise to ensure that your project is completed to a high standard. 

They can also provide advice on the best plastering materials and techniques for your specific project. Professional plastering services often come with a guarantee or warranty, giving you peace of mind that your project is in good hands.


Preventing plastering mishaps requires attention to detail and proper techniques. While these common errors can be avoided, it’s important to remember that plastering is a skilled trade that requires proper training and experience. 

It’s usually preferable to see a professional plasterer if you’re unsure about your plastering skills. They can provide expert advice and ensure that your project is completed to a high standard.
