Determining whether your walls require plastering or merely a fresh coat of paint can be a challenging decision. The appearance and condition of your walls play a significant role in maintaining the aesthetic of your home.
Whether you’re renovating or simply refreshing a room, it’s essential to differentiate between the two to avoid unnecessary work and costs.
In this guide, we’ll explore the key indicators that can help you decide whether plastering is necessary or if a new paint job will suffice.
Common Signs Your Walls Need Plastering
Plastering is a specialised task that involves applying a layer of plaster to the walls, which gives them a smooth, even finish. However, plastering isn’t always the right solution. Sometimes, a simple paint job can restore the look of your walls. Here are several signs to look for to determine if plastering is required.
Cracks In The Walls
One of the most common signs that your walls may need plastering is the presence of visible cracks. These cracks can appear in various forms, such as:
- Hairline cracks: Small, thin cracks can form due to natural settling of the house or temperature changes.
- Large cracks: These typically indicate more severe structural issues that may need plastering or even repair work on the wall structure.
If the cracks are deep or have worsened over time, plastering may be required to restore the integrity of the walls.
Damp Patches Or Mould
Dampness is another clear indicator that your walls need attention. Moisture can seep into walls due to leaks, poor ventilation, or rising damp. If you notice any of the following, your walls likely need replastering:
- Damp patches: Wet spots on your walls that don’t dry out over time.
- Mould growth: Black or green mould growing on your walls is a sure sign of dampness.
In this case, plastering will not only restore the aesthetic but also help with moisture control.
Uneven Surfaces
If your walls appear uneven or bumpy, it could be due to poor plastering jobs in the past or wear and tear. Uneven walls can make it difficult for paint to adhere properly, which may affect the overall finish. When walls are severely damaged, plastering may be the most effective solution.
Peeling Or Flaking Paint
In some cases, peeling or flaking paint can be a result of moisture or age. However, if the underlying plaster is cracked or damaged, paint will not adhere properly, causing it to peel off. If you find this issue in several areas of your home, replastering may be needed to provide a stable surface for painting.
Bulging Or Warped Walls
Walls that have started to bulge or warp may indicate that the plaster is no longer secure. This could occur due to issues such as dampness, improper application, or the house settling. If the bulge is severe, plastering will be required to level the surface.
Signs Your Walls Only Need A Paint Job
While plastering may be necessary in some cases, there are times when a simple paint job is enough to restore the look of your walls. Here are some signs that your walls might only need a fresh coat of paint:
Fading Or Discolouration
Over time, paint can fade or become discoloured due to sun exposure, smoke, or everyday wear and tear. If your walls appear dull or yellowed but are free from cracks or other issues, a fresh coat of paint may do the trick.
Stains And Marks
Stains from spills, dirt, or fingerprints are common on walls, especially in high-traffic areas like hallways and kitchens. These stains are often superficial and can be cleaned or painted over to restore the wall’s appearance.
- General stains, such as water marks, grease stains, or general dirt marks, can often be removed with a thorough cleaning. If cleaning doesn’t work, a new coat of paint will likely cover up the stains.
Textured Walls Or Wallpaper Removal
If you have textured walls or wallpaper that has begun to peel, it may need a new coat of paint. Textures such as stucco or popcorn ceilings can sometimes make walls look dated or damaged, but a good paint job can update the appearance without requiring extensive plastering.
Minor Nail Holes Or Dents
Small holes from nails or dents caused by everyday activities are standard in any home. These issues can be fixed easily with a patching compound and a new coat of paint. If the damage is isolated to a small area, this will not require replastering.
No Major Structural Issues
If your walls appear smooth and stable with no visible cracks, bulges, or signs of dampness, all your walls likely need is a coat of paint. If the underlying plaster is in good condition, you can save yourself the expense of replastering.
How To Fix Wall Damage: Plastering Vs. Painting
Now that you know the signs for both plastering and painting, let’s look at how to address the damage.
When To Replaster Your Walls
Replastering is typically needed when the damage is more severe, such as when the plaster has cracked, bulged, or is affected by dampness. The process involves scraping away the old plaster and applying a new coat to restore the wall to its original condition. Replastering is ideal if the damage is extensive or if you’re preparing to repaint the walls for a smoother finish.
When To Simply Repaint Your Walls
Repainting is a less intrusive option when the damage is superficial. It is an excellent choice for refreshing the colour, covering minor stains, or fixing light fading. If the walls have no significant structural issues and are free from cracks, painting is usually the best and most cost-effective solution.
How To Know Which Option Is Right For You
To determine whether your walls need plastering or just a paint job, you can try the following:
- Assess the damage: If the damage is limited to surface-level issues, a paint job may suffice. If the damage is more extensive or structural, consider plastering.
- Consult a professional: A plastering expert can help assess the condition of your walls and recommend the best course of action. A professional can provide guidance on whether plastering is necessary or if painting will restore the appearance of your walls.
Conclusion
Determining whether your walls need plastering or just a fresh coat of paint can be a tricky decision. The key is to identify the extent of the damage. If the damage is superficial, a new coat of paint will usually suffice.
However, if your walls have deep cracks, dampness, or significant structural damage, plastering will be required to restore the surface. When in doubt, consulting with a professional will help you make the best decision for your home.
Frequently Asked Questions
How Can I Tell If My Walls Need Plastering Or Just Painting?
To determine whether your walls need plastering or just a paint job, inspect the surface for cracks, bulges, or damp patches. If there are visible deep cracks or structural damage, replastering may be required. On the other hand, if the walls are mainly stained or discoloured without significant damage, a fresh coat of paint should suffice.
How Much Does It Cost To Replaster A Wall Compared To Painting It?
Replastering tends to be more expensive than painting, as it involves a more intensive process that includes removing old plaster and applying new layers. The cost will depend on the size of the area being worked on, the extent of damage, and whether additional repairs are required. A simple paint job, however, is a more affordable and less labour-intensive option.
Can I Repaint My Walls If They Have Minor Cracks?
Yes, minor cracks can be fixed by patching them up before repainting. If the cracks are hairline or not severe, simply filling and smoothing them out should be enough for a fresh coat of paint. However, if the cracks are large or getting worse, it may be a sign that replastering is needed for a more lasting solution.
