At Roundtower Lime, we supply a curated range of natural, breathable paints designed specifically for external traditional buildings and conservation projects. Our range includes limewashes, lime paints, and the internationally respected Beeck mineral paint system, all of which offer vapour permeability, durability, and aesthetic authenticity.
These paints are ideal for solid masonry, lime plaster, stone, and other breathable substrates, allowing moisture to move freely through the wall while providing exceptional weather resistance and colourfastness.

Frequently Asked Questions (FAQs)
Why is breathability important in paint?
Breathable paints allow moisture vapour to escape from walls, preventing damp buildup, mould, and paint failure. This is essential for solid masonry and lime-plastered walls with no cavity or modern damp-proofing.
Can I paint over modern emulsion or acrylic paint with mineral or lime paint?
No – both lime and mineral paints must be applied directly onto breathable substrates. Any non-breathable acrylic or plastic paints should be fully removed beforehand to avoid adhesion or breathability issues.
Are Beeck paints suitable for exposed external locations?
Yes – Beeck Renosil is specifically formulated for external applications, offering high weather resistance, colourfastness, and long-term durability even in harsh coastal or wet environments.
Can I colour-match my paint choice?
Yes – we offer a wide range of natural mineral colours and can assist with finding a suitable match within the Beeck and lime pigment range. Custom colours may also be available on request.
