As a homeowner, knowing how to plaster your walls to achieve a smooth finish properly is important. However, many people make common mistakes that can result in a less-than-perfect outcome.
This article discusses the plastering mistakes to avoid to get a smooth finish.
Not Preparing the Surface Properly
One of the most common mistakes people make when plastering their walls is not preparing the surface properly. Make sure the wall is clean, dry, and clear of any dirt before beginning the plastering process.
Any bumps or uneven surfaces should be sanded down, and any holes or cracks should be filled with a suitable filler.
Skipping the Sealant
Another critical step often overlooked by many is applying a sealant to the wall before plastering. Sealants are necessary to provide a good bond between the plaster and the wall surface.
The plaster may not adhere correctly without a sealant, leading to an uneven finish. A sealant also helps to prevent moisture from penetrating the wall, which can cause the plaster to crack or peel over time.
Mixing the Plaster Incorrectly
Mixing plaster is an art that requires precision. One of the most common mistakes people make is not mixing the plaster correctly.
If the plaster is not mixed to the right consistency, it can lead to a lumpy or uneven finish. The plaster should be mixed in small batches, precisely following the manufacturer’s instructions.
This will ensure that the plaster is mixed to the correct consistency and there are no lumps or air pockets.
Using the Wrong Tools
Using the right tools is crucial when plastering. Many people make the mistake of using the wrong tools, resulting in a less-than-perfect finish.
A plastering trowel is the most important tool when plastering, and it’s essential to choose the right one for the job.
A trowel that is too small will make the job harder, and a trowel that is too big will make it difficult to control the plaster.
It’s also essential to have a hawk, which is a flat tray used to hold the plaster, and a mixing paddle to mix the plaster.
Not Working Quickly Enough
Plastering is a time-sensitive job, and working quickly to achieve the best results is essential. Many people make the mistake of not working quickly enough, resulting in an uneven finish.
Plaster sets quickly, so it’s important to work in small sections and apply the plaster as quickly as possible. If the plaster starts to dry before it’s smoothed out, it can lead to an uneven finish.
Not Sanding between Coats
When plastering, applying several coats to achieve a smooth finish is essential. However, many people make the mistake of not sanding between coats, resulting in a rough or uneven finish.
Sanding between coats helps to remove any bumps or imperfections, allowing for a smoother finish. Letting each coat dry completely before sanding is essential to avoid damaging the plaster.
Not Allowing Enough Drying Time
Allowing enough drying time between coats is crucial when plastering. Many people make the mistake of not allowing enough drying time, resulting in a less-than-perfect finish.
It’s essential to follow the manufacturer’s instructions on drying times for each coat of plaster. Rushing the drying time can lead to cracking or peeling of the plaster, which can be difficult to repair.
Plastering is a delicate process that requires attention to detail and precision. You can get a clean and expert-looking finish by avoiding these common blunders. With the tips provided above, you’ll be well on your way to achieving a beautiful finish on your walls.
