If you’re planning a home renovation in Cheltenham or across the Cotswolds, understanding lime plaster before work begins is essential. Lime plaster is a breathable, durable material that preserves historic charm while improving indoor comfort. But it’s not like modern plaster: preparation is key. This lime plaster guide will help you get ready and avoid common mistakes.
1. Assess Your Property
Start by inspecting the walls. Solid masonry, stone, and brick surfaces are ideal for lime plaster. Check for:
- Existing cracks or loose plaster
- Damp patches or rising moisture
- Previous cement-based coatings
Cement plasters are incompatible with lime plaster, as they trap moisture. You can read more about this in our guide Can you put lime render over cement render?
2. Plan Your Surfaces
Decide which walls or ceilings need plastering. Some surfaces may need lath or mesh preparation for better adhesion. Removing old, incompatible materials ensures long-term success.
We specialise in lime plastering for domestic buildings and can assess your surfaces for optimal results.
3. Choose the Right Lime Mix
Not all lime plasters are the same. Options include:
- Hydraulic lime – sets quickly, suitable for exterior walls or damp areas
- Non-hydraulic lime (lime putty) – best for interiors and historic restorations
Selecting the right mix ensures durability, breathability, and finish quality. Learn more about our lime plastering services in Cheltenham.
4. Consider Timing and Environment
Lime plaster sets slower than modern gypsum plaster. Temperature, humidity, and drafts affect curing. Avoid working during extreme heat or frost.
Plan your renovation schedule carefully. Proper curing prevents cracks and ensures a smooth, long-lasting finish.
5. Protect Surroundings
Lime plaster is safe but can burn skin on contact when wet. Dust is also an irritant. Protect floors, furniture, and yourself:
- Use drop sheets
- Wear gloves and goggles
- Keep the area ventilated
For professional application, our modern plastering and lime plastering team handles all health and safety considerations.
6. Prepare for Finishing
Decide whether you’ll apply limewash or breathable paint. These finishes maintain the plaster’s natural properties. Avoid non-breathable coatings like vinyl paint, which can trap moisture and damage the walls.
We often recommend breathable paint for lime plaster for a lasting, natural finish.
7. Work With Local Experts

- Finishing plan is ready
Following this checklist ensures your lime plaster project goes smoothly, preserving both the beauty and breathability of your home.
