The Benefits of Using Saint-Astier Lime Products

Choosing the correct lime is one of the most critical decisions in building conservation. Saint-Astier Natural Hydraulic Lime (NHL) products are globally renowned because they work in harmony with historic masonry, helping solid walls manage moisture, movement, and long-term durability.

Why Choose Saint-Astier NHL?

Unlike dense, impermeable cement mortars that trap moisture and accelerate brick decay, Saint-Astier NHL allows moisture vapour to safely pass through the wall. This breathability ensures older buildings can dry out naturally after heavy rain or seasonal damp.

Beyond moisture control, Saint-Astier lime offers vital elasticity. Older buildings shift subtly with seasonal temperature changes and foundation settlement. A rigid cement repair will crack under this stress, but Saint-Astier NHL accommodates modest movement sympathetically.

Core Heritage Applications

Saint-Astier lime is a pure natural hydraulic lime, completely free from artificial additives like gypsum or cement. This purity makes it the premier choice for conservation-minded repairs. It excels in:

• Repointing: Renewing eroded joints while protecting softer historic brickwork.
• External Rendering: Shielding exposed walls without trapping internal condensation.
• Masonry Bedding: Laying traditional flint, stone, and period brickwork safely.
