To attain a polished look when plastering walls, one must pay close attention to detail and use the correct technique. However, a less-than-perfect finish is often the consequence of a number of typical errors made by unskilled plasterers. A typical blunder is not priming the wall adequately before applying plaster. Not priming the surface before laying plaster, not washing the wall adequately, or failing to fix holes or fractures are all examples of such mistakes.
Applying an excessive amount or an insufficient amount of plaster is another typical error. If you apply too much plaster, it will be thick and uneven, making it hard to work with and even more likely to break as it cures. Conversely, if you use too little plaster, the finish will be uneven and won’t adhere well to the wall. If you want a smooth and long-lasting finish, be sure to apply the plaster uniformly and at the right thickness.
Inadequate drying time between applications of plaster is another typical error. It is important to wait for plaster to dry and cure completely before adding more coats; doing so can cause the finish to be weak and unstable. Before adding more coatings or embellishments, make sure the plaster has dried completely, following the manufacturer’s recommendations.
Plastering Mistakes: What They Are and How to Prevent Them
Plastering is analogous to fortifying walls with an additional armour layer. Like every other aspect of building, plastering’s advantages are contingent upon its correct application. When you make a mistake, you must own up to the consequences.
Despite appearances, plastering is a complicated process. A specialist is required to execute plastering work correctly.
Not Allowing Enough Time for Drying
Every plasterer knows that to prevent shrinkage, there must be sufficient drying time between applications.
However, with sufficient drying time when setting, plasterers in today’s market, who are in high demand, may be able to complete work on time.
You can end up with “high joints” if you apply three coats of paint without allowing enough drying time in between. When homeowners switch on the lights in their house and notice lines and joints in the plaster, it happens under specific lighting circumstances.
Luckily, it’s easy to repair because it’s caught early enough. Just add another coat if you’re dealing with shrinking and hollow joints.
But when the house is finished, the residents move in, and the joints are apparent when the lights are turned on, it becomes a big deal. Then a complete repair and painting are in your future.
Preventing shrinking and expensive repairs begins with using the correct product for the job and following the instructions to the letter, including allowing enough drying time.
Over Sanding
When discussing the first point, the problem of over-sanding is relevant. Nowadays, most plasterers set the home and hire a contract sander to smooth out the finish and hide any noticeable gaps.
Nevertheless, issues might occur when sanders ‘over-sand seams reveal them. The sole solution to this problem is to apply an additional layer, which necessitates more sanding.
You may prevent this issue using the appropriate grit sandpaper on your sander for the compound you have applied.
To prevent over-sanding, it is crucial to inform your sander of the recommended grit for sanding, as there is a wide range of tougher and softer compounds available. The difference between fixing an issue after it has already happened and preventing it altogether can be as simple as staying on top of things and maintaining open lines of communication.
Neglecting to Consider Fainting Light
It is common knowledge among plasterers that ‘glancing light’ must always be considered. Certain lighting circumstances, such as early morning, different seasons of the year, or rooms with floor-to-ceiling windows, can make seams and lines more noticeable due to glancing light.
Even if a plasterer does an excellent job setting, sanding, and painting the surface, it might still look uneven or show the joints in specific lighting or areas of the house. Glancing light is only sometimes a sign of poor artistry.
You can suggest goods and finishes that can lessen the effect of glancing light during the quotation phase, which is the ideal time to address possible glancing light issues.
Bright Lights: LEDs and Fluorescents
Problems abound for plasterers when working with fluorescent and LED lights. It is not uncommon for fluorescent lights to cast a shadow across the ceiling and even appear on the joints in the ceiling. LED light strips mounted on bulkheads are becoming more and more common, but they have the potential to shine a bright light directly onto your setting, drawing attention to any flaws in the plasterboard or the finish.
To head off problems later on, it’s important to know what kind of lighting the owner has in mind before beginning the project and to advise them on how their walls and joints would look under those lights.
Even with careful positioning and sanding, lights installed on walls, such as those in stairwells, will cast shadows on joints and faults. Preventing headaches later in the process is possible if you warn the homeowner about these problems.
Additionally, it might be useful to be familiar with the standard for inspecting plasterboard finishes. When checking surfaces for flaws or colour variations, these pertain to the “normal viewing position” and the “non-critical light” that hits the surfaces.
FAQs About Plastering
Why Should Plaster Be Kept Moist During The Curing Process?
Keeping plaster moist during curing prevents rapid drying, leading to shrinkage cracks and weakened bond strength. Spraying water or using curing compounds helps maintain optimal moisture levels.
What Are The Consequences Of Ignoring Environmental Conditions During Dumping?
Ignoring environmental conditions such as temperature, humidity, and ventilation can result in uneven drying, prolonged curing times, and an increased risk of mould or mildew growth on the plastered surface.
How Does Using Improper Tools Affect The Quality Of Plastering Work?
Using the right tools or equipment can make achieving a smooth and consistent plaster finish easier. Investing in high-quality tools and proper equipment ensures better results and reduces the risk of errors.
What Are The Risks Of Neglecting Quality Control During Placement?
Neglecting quality control can lead to inconsistencies in plaster thickness, texture, and finish, compromising the overall appearance and durability of the plastered walls.
How Can One Avoid Common Mistakes And Ensure A Successful Plastering Project?
To avoid common mistakes, following best practices, adhering to manufacturer guidelines, investing in proper training and equipment, and paying close attention to details throughout the plastering process are essential.
Negligently Selecting a Material for Your Tool
Equipment used by plasterers, such as mud boxes, bazookas, and taping machines, can have their useful lives drastically reduced if the materials used for them are not properly matched.
The most common area where plasterers get trapped because they use improper products is with taping machines. A plasterer’s crew needs to be well-versed in the proper use of tools and match compounds and supplies to the equipment and the task at hand.
The Ratio Is Wrong
Using the wrong proportions of ingredients is another common mistake. For the best consistency, a certain ratio of plaster to water must be followed. If not, the final product may be too thin or brittle. Take plaster and water measurements exactly as directed by the manufacturer.
Not Using the Right Plaster Mixture
Plaster that has air gaps and bumps in the finish as a result of uneven mixing. This can be avoided if the plaster is mixed well and consistently, making sure to scrape the bottom and rims of the container often to integrate all of the plaster.
Using the Wrong Approach
The technique used to apply plaster might also influence its final look. It is important to feather the edges correctly and avoid applying too much plaster in one place since this might result in uneven surfaces. A smooth, uniform finish requires the correct trowel and pressure when applying plaster.
Skipping Over the Sanding and Smoothing Bits
A perfectly smooth surface can only be achieved by meticulously sanding and polishing. You can prevent lumps and uneven textures by following this procedure. Ensure the plastered surface is smooth before applying the final layer using a sanding block and fine-grit sandpaper.
Using the Trowel Incorrectly
Using too little of a trowel is another common mistake, particularly among do-it-yourselfers. A smooth yet delicate finish can be achieved by trowelling the plaster too much, which weakens and brittles the material. It is essential to stop trowelling the plaster after it has reached the appropriate smoothness.
Difficulty in Fixing Core Issues
Plastering will not fix structural problems; ignoring them will cause cracking and other problems to persist. It is important to check for any hidden structural issues before plastering begins.
Plaster Thickness Regulation is Depressing
For optimal results, maintain a consistent plaster thickness throughout the project. It may be easier to smooth down and cover surfaces with paint or wallpaper if the plaster is of uneven thickness. Checking the thickness frequently using a straight edge will help you avoid this mistake.
Lack Of Airflow
Adequate ventilation is crucial to the finishing process and how quickly it dries. Proper ventilation is essential for the plaster to dry and cure correctly.
Need It Done Quickly
Plastering is a tedious yet rewarding craft that requires a lot of persistence and effort. If you rush to finish the job, you risk ruining the walls instead of repairing them. The walls of your home will look better if you take your time and do a good job the first time around.
Ignoring The Problems
Challenges in building projects are ever-evolving. There are peculiarities even in plastering. These things should be considered before you start working on the project. If you apply the wall plaster before doing the required homework, the situation will only get worse. Get a feel for the typical obstacles faced by people in this field by studying them.
Carelessness With Details
Plastering is a detailed process that requires precision. Not paying enough attention to corners, edges, and connections can make imperfections stand out. Make sure you thoroughly cover and smooth out every single place.
Disregarding Safety Measures
Safety is paramount during plastering since dangerous materials must be handled. Not using common sense safety equipment, such as goggles, gloves, and a dust mask, can lead to serious injuries or health complications. Use the right safety gear in a well-ventilated area.
Using Cheap Tools
Buying inexpensive tools may seem like a good idea at the time. Still, they will end up costing you more money because poorly done work is inevitable with inexpensive instruments. You should get good tools if you want your plastering to turn out well. You don’t have to break the bank to do it; what is important is that you purchase high-quality goods from a trustworthy vendor. Your tools will perform better and endure longer.
Not Cleaning Your Tools
Plaster gets all over your equipment after a long day of working with it, so it’s tempting to put them down, brew a cup of tea, and call it a day.
There will be a major issue when you come back the next day. Your tools may become useless from the solidified plaster, and you’ll need to scrape twice as much to remove the excess. Take a few minutes out of your session to tidy up your tools. Doing so will keep them in better shape and guarantee you are ready to begin the following session immediately.
Drying and Finishing
Common mistakes made when drying and finishing plaster include not waiting for it to cure fully before applying a finishing coat, improperly sanding the surface and incorrect priming or painting of the surface. Here is some guidance on how to stay away from these typical problems:
- Before applying a final coat or between coats of plaster, be sure the material has dried entirely. This way, you won’t have to worry about sagging or cracking.
- Make sure the surface is smooth using fine-grit sandpaper to remove any bumps or imperfections from the plaster. This will help smooth out any bumps and provide a more consistent look.
- Ensure proper priming and painting of the surface: When applying a primer designed for plaster, follow the manufacturer’s instructions. Wait until the primer is dry before painting.
- Avoid working it too much while smoothing it out to keep the plaster from thinning and weakening.
- Too much finishing coat could cause the surface to buckle and crack, so be careful not to apply it in a thick layer. Apply a thin finishing coat layer and allow it to cure entirely instead of priming, painting, or sanding.
If you follow these steps, you should not have any issues with the plaster drying and finishing processes and be able to achieve a lasting finish.
