Can I Plaster a Wall Myself?
Plastering is an essential part of getting smooth walls, whether it’s a new build or a renovation. So, can I plaster a wall myself? Yes, but with lots of challenges. Getting a professional finish on your own walls is more than just slapping on a coat of plaster – it requires preparation, skill and the right plastering tools.
DIY plastering may seem appealing, but it’s a job that requires careful work and an understanding of how to deal with uneven surfaces, loose plaster and dried plaster. Below we’ll look at why hiring a professional plasterer generally gives you better, longer lasting results.
DIY Plastering Challenges
1. Preparation is Everything
Before you start plastering you need to prepare the wall correctly. This means:
-
Removing old wallpaper and clearing debris to get a dust free surface.
-
Repairing loose plaster or cracks in the existing plaster.
-
Cleaning the wall and applying PVA glue for better adhesion.
-
Making sure all tools are clean – a clean bucket and stainless steel trowel.
For old walls you may need to fix plasterboard sheets or stabilise rougher surfaces so your new plaster sticks properly.
2. Mixing Plaster
Getting the right mix is crucial. A power mixer or drill attachment will give you a consistent mix and no lumps that can ruin your finish. The mix should be smooth but not runny – often described as thick cream. Always follow the manufacturers instructions on your plaster product to get the right ratio.
Without experience mixing plaster can lead to plaster waste or batches that dry too quickly and add extra challenges.
3. Application
Applying plaster is not as easy as it seems. Professionals use good quality tools like a plastering trowel, bucket trowel and hawk board to get a smooth finish. The process involves:
-
Applying the first coat of plaster evenly, about 2-3mm thick to cover imperfections.
-
Using a stainless steel trowel at a slight angle to spread the plaster over the whole surface.
-
Allowing the plaster to dry slightly before applying the second coat, a thinner layer for the final skim coat.
-
Using a spray bottle to keep the plaster workable as you smooth rough edges and fill gaps.
Even with basic tools beginners struggle with trowel marks, uneven application and keeping edges clean.
4. Finishing
For a professional finish you need to make sure the plaster is smooth before it’s completely dry. A wet paintbrush or a light mist over the surface will help blend the areas together. Once dry you can sand any minor imperfections with fine grit sandpaper.
But DIY will give you rough edges, uneven surfaces and no perfectly flat finish that a professional plasterer will get.
Why You’re Better Off Hiring a Pro
1. Speed and Skill
A professional plasterer can plaster a wall quicker and better, they can handle rougher surfaces or damaged old plaster with ease. They know how to apply a thin coat evenly over the whole wall and get a smooth finish.
2. Right Tools
Professionals have the best tools – multi-finish plaster, plastering trowels and hawk boards – to get precision and durability. They also know how to keep tools clean throughout the process so the plaster doesn’t dry on them and ruin the finish.
3. Cost Effective in the Long Run
DIY plastering might seem cheaper but mistakes will cost you more to fix. Uneven surfaces, excess plaster or cracks in the finish will mean you’ll need to hire a professional anyway. A professional job will get you a perfect flat finish first time.
4. Consistency Across Multiple Walls
For whole house or large wall projects professional plasterers will give you uniform results that are hard to achieve with DIY.
When DIY Plastering Makes Sense
While professional help is recommended, there are times when DIY plastering might be okay:
-
Small Repairs: Fixing small cracks or applying a thin layer to patch areas.
-
Practice Spaces: Practicing on less visible surfaces like garages or utility rooms.
-
Non-Critical Areas: For areas where a professional finish doesn’t matter.
Even in these cases you’ll need basic tools like a stainless steel trowel, hawk board and a clean bucket to get decent results.
