• Purpose: To create a flawless, smooth surface on walls and ceilings. It’s ideal for covering textured finishes, minor cracks, and imperfections.
• Materials: Specialist finishing plasters like Weber Mason Wall Putty or multi-finish plasters are commonly used.
• Benefits: Faster and cheaper than replastering, less mess, and ideal for renovation projects.
• Also known as: Skim coat, finishing coat, or setting coat.

💰 Skimming Cost Data

Based on our main plastering cost guide and industry data from LocalPros, here are the current price ranges for skimming.

🤔 When to Skim vs Replaster

Choosing between skimming and replastering depends on the condition of your existing walls and your goals. Use this guide to decide.

📋 Skim Coat Application Guide

For a professional result, follow these steps carefully.

🦏 Skimming Over Rhinolite

As detailed in our cement vs Rhinolite guide, Rhinolite requires special preparation before skimming.

• Test first: Perform the damp cloth test. If the plaster is powdery, it must be sealed.
• If powdery: Apply 2 coats of Paintcor’s RhinoSeal, allowing 48 hours drying between coats.
• Then: Apply a coat of PlasterPrime before skimming.
• Important: Never apply Fillercoat directly to Rhinolite without first applying Top Paints’ Bonding Liquid (24 hours drying).
• Alternative: For severely powdery Rhinolite, full replastering may be a better option.

🎨 Skim Coat Over Existing Paint

Yes, you can skim over existing painted walls, but preparation is critical. Follow this guide from Paintcor and industry best practices.

1. Assess the paint: Ensure it’s sound and not peeling. Remove all loose or flaking paint.
2. Clean: Wash walls with sugar soap to remove grease and contaminants.
3. Sand: Sand glossy surfaces to a matt finish to provide a key.
4. Prime: Prime exposed plaster areas with a suitable primer like AcrySeal (diluted 1:1 with water). For the entire wall, a bonding agent is recommended.
5. Apply skim: Apply the skim coat in thin layers as per the application guide above.

⚖️ Skimming vs Plasterboarding Cost

For ceilings, you might also consider plasterboarding (dry-lining). Here’s a cost comparison.

• Skimming an existing ceiling: R145 – R185 per m². This is the cheaper option if the existing ceiling is sound.
• New plasterboard ceiling + skim: R180 – R250 per m² (as per our cost guide). This is more expensive but creates a new, perfect surface and allows for insulation.
• Which is better? Skim if your existing ceiling is in good condition. Plasterboard if the ceiling is damaged, you want to add insulation, or you need to hide services.

📍 Skimming Costs by Major City

Here are estimated costs for standard wall and ceiling skimming (labour + materials) in different regions.

• Johannesburg & Sandton: R150 – R190 per m²
• Pretoria & Centurion: R145 – R185 per m²
• Cape Town & Bellville: R155 – R195 per m²
• Durban & Umhlanga: R150 – R190 per m²
• Stellenbosch: R155 – R200 per m² (higher demand for premium finishes)

❌ 7 Common Skimming Mistakes

1. Mistake #1: Inadequate surface preparation. Skipping cleaning, sanding, or priming leads to poor adhesion and cracking. See our preparation guide.
2. Mistake #2: Skimming over peeling paint. The skim coat will also peel. Remove all loose paint first.
3. Mistake #3: Applying the coat too thick. A skim coat should be 2-3mm. Too thick and it will crack or slump.
4. Mistake #4: Not controlling suction. Failing to prime a very porous wall will cause the skim to dry too fast and crack.
5. Mistake #5: Poor trowel technique. Leaving trowel marks or ridges requires extra sanding. A skilled plasterer is essential.
6. Mistake #6: Skimming over powdery Rhinolite without treatment. This is a guaranteed failure. Always test and seal first.
7. Mistake #7: Rushing the drying time. Skim coats need 24-48 hours to dry before painting. Painting too soon traps moisture and causes peeling.

Many of these are covered in our common mistakes guide.
