When it comes to giving your walls a smooth, flawless finish, two common terms often come up: plastering and skimming. But what do they really mean? And more importantly, which one is best for your New Zealand home? Whether you’re building a new house in Wellington or renovating a classic villa in Lower Hutt, understanding the difference between plastering and skimming can help you make the right decision for both quality and cost.

What Is Plastering?

Plastering involves applying a thick coat of material to bare walls or ceilings to create a durable, even surface. It’s often the go-to solution for new builds or homes with damaged walls that require a full structural repair before painting.

In many Wellington and Lower Hutt properties, plastering plays a crucial role in achieving long-term wall protection, especially in older homes where cracks or uneven Gib surfaces are common. For homeowners planning full renovations or new constructions, opting for professional plastering services is often the first step in the interior finishing process.

Plastering isn’t just about looks , it strengthens walls, provides some insulation, and creates a perfect base for whatever finish you choose next, whether it’s paint, wallpaper, or decorative plaster.

What Is Skimming?

Skimming, on the other hand, is a technique used to apply a very thin layer of plaster usually over already-prepared or painted surfaces. It’s a common choice when walls are generally in good condition but have minor imperfections or patchy textures.

It’s frequently used before repainting to ensure a smooth, high-quality finish, particularly in homes where an interior painting project is underway. Skimming can also help unify the texture of walls where previous patchwork repairs have left noticeable differences.

For rental properties or homes getting a quick makeover, skimming is a cost-effective way to breathe new life into tired walls without the time and expense of full plastering.

Plastering vs Skimming – What’s the Difference?

While both processes aim to create smooth walls, the key difference lies in the thickness and purpose of the plaster applied:

• Plastering: A thicker layer (usually 5-15mm) applied on new or damaged walls.
• Skimming: A very thin layer (1-3mm) applied mainly for surface smoothing and finishing.

Plastering is more labor-intensive and typically costs more, but it provides a stronger, more durable surface. Skimming is quicker and less expensive, making it ideal for minor repairs or surface preparation.

Choosing the Right Option for Your NZ Home

In New Zealand homes, the choice between plastering and skimming often comes down to wall condition and renovation goals. For example, if you’re refreshing a rental unit for re-letting in Petone, skimming may offer a quick and cost-effective upgrade. But if you’re dealing with damaged plasterboard or renovating an older home with cracked interior linings in suburbs like Naenae or Eastbourne, plastering is usually the better long-term investment.

We’ve seen this first-hand in Upper Hutt and Petone, where traditional villas often require both, plastering to restore the base, and skimming to refine the surface before painting. Homes in coastal areas like Eastbourne or Wainuiomata can also benefit from this two-step approach to tackle moisture-related damage.

Local Knowledge Matters

Unlike overseas trends, NZ homes particularly in the Wellington Region deal with a unique combination of seismic movement, moisture, and rapid temperature changes. These conditions influence not just the materials we use, but the techniques required to achieve long-lasting finishes.

With years of experience across suburbs like Naenae, Eastbourne, and Wainuiomata, knowledge of common Gib issues, paint failures, and previous surface treatments allows for recommending approaches specific to the home’s history and structure.

For example, older homes might have been plastered with traditional lime-based materials, which behave differently than modern gypsum plaster. Understanding these nuances is vital for ensuring repairs bond well and last.

Planning Your Next Wall Upgrade

If your walls are showing signs of wear or you’re preparing a space for resale or rental, addressing the plaster layer is often one of the most cost-effective ways to add value and visual impact. Whether it involves full re-plastering or a skim coat prior to painting, a site assessment will give a clear picture of what’s needed.

Some signs your walls might need plastering include visible cracks, large dents, water damage, or exposed plasterboard sheets. If the walls just feel rough to the touch or have slight texture differences, skimming may be enough.

How Long Does Each Process Take?

Plastering usually takes longer because the thicker layers need time to dry properly, typically between 3 to 7 days, depending on conditions. Skimming, being thinner, can often be completed and dried within a day or two.

Keep in mind that humidity and temperature in NZ can affect drying times, especially in winter months or damp coastal areas like Eastbourne.

Common Questions About Plastering and Skimming

h. Preparation with plastering or skimming is key to a professional-looking paint job that lasts.

Is plastering or skimming better for rental properties?
Skimming often makes sense for rentals because it’s quicker and cheaper, giving walls a fresh look without major renovation costs. However, severely damaged walls may require plastering for durability.

What kind of plaster is used in NZ homes?
Gypsum plaster is most common for interiors, but cement or lime-based plasters are sometimes used, especially in older homes or wet areas.

Can skimming be done in bathrooms or kitchens?
Skimming is fine on dry walls, but moisture-prone areas usually need moisture-resistant plaster and proper waterproofing.

Final Thought

Understanding the difference between plastering and skimming allows you to make more informed decisions about home improvement projects. Both have their place, it’s all about the condition of your walls, your budget, and the finish you’re after.
