Many homeowners and renovators in Cape Town, Stellenbosch, Paarl, and Somerset West often confuse skimming with plastering. While both involve applying a finish to walls and ceilings, they serve different purposes and require distinct techniques. Understanding the difference helps you hire the right contractor and achieve smooth, durable walls for your home or office.
1. What is Plastering?
Plastering is the process of applying a thick coat of plaster to bare brick, block, or concrete walls. It:
- Levels uneven surfaces
- Covers cracks and gaps
- Creates a base for painting, skimming, or tiling
Plastering is usually applied in 2–3 coats and can be rough or smooth depending on the intended finish. For example, a commercial office in Bellville required full plastering on exposed brick walls before painting and decoration.
2. What is Skimming?
Skimming, also called skim coat, is the final, thin layer applied over plastered walls. It:
- Provides a perfectly smooth finish for painting or wallpaper
- Hides minor imperfections in plaster
- Enhances the appearance of ceilings and walls
Skimming is usually done in one or two thin coats and is highly recommended for interior walls in modern homes. A recent home renovation in Stellenbosch involved skimming all living areas to give a clean, sleek look.
3. Key Differences Between Skimming and Plastering
| Feature | Plastering | Skimming |
|---|---|---|
| Purpose | Base coat, levels surfaces | Smooth finish, cosmetic improvement |
| Thickness | 8–12mm | 1–3mm |
| Surface | Applied on raw walls | Applied on plastered walls |
| Tools | Trowel, hawk | Trowel, sponge float |
| When Used | During initial wall preparation | Before painting or decorating |
Understanding these differences helps homeowners hire the right service for their needs, whether for a new build in Paarl or a ceiling renovation in Somerset West.
4. When to Use Each
- Plastering: New walls, walls with cracks, uneven surfaces, or after demolition
- Skimming: Existing plastered walls, ceilings, or minor repairs needing a smooth finish
For example, a Bellville client had plastered walls with small imperfections. Skimming was enough to achieve a flawless finish without re-plastering the entire area.
5. Choosing the Right Contractor
Hiring an experienced contractor ensures the work is done correctly and lasts longer. Look for:
- Years of experience in both plastering and skimming
- References or portfolio of past projects
- Use of quality plaster and skim coat materials
A contractor familiar with Cape Town conditions, like coastal humidity or older homes in Stellenbosch, will adjust techniques to prevent cracking or peeling.
6. Benefits of Skimming and Plastering
- Smooth, professional-looking walls and ceilings
- Enhanced durability and longevity
- Better paint adhesion and aesthetics
- Increased property value
Local example: A renovated home in Paarl had all living spaces plastered and skimmed. The result was smooth, modern walls ready for painting, impressing the homeowners and improving property appeal.
