- Attractive through coloured finishes available in a wide range of shades
- Suitable for both renovation and restoration projects where authenticity and performance are essential
Why Use Lime Renders?
Lime plasters have been used for centuries in building construction and remain essential for the conservation of historic structures. Unlike cement-based renders, lime plasters are porous and allow water vapour to escape, helping buildings “breathe” and preventing trapped moisture. Any fine cracks that form can often self-heal, preserving the integrity of the surface over time.
By choosing lime renders, you ensure:
- Respect for the original building materials and construction methods
- Healthier interiors through improved vapour permeability and reduced risk of the appearance of mould or fungi
- Enhanced aesthetic quality with brightness, regional colour matching and a natural finish
- Reversible coatings that allow future restoration work without damaging the substrate

FAQ
Heritage lime render is a breathable, flexible plaster composed of lime, sand and water. It allows moisture to escape, prevents condensation and damage in historic masonry, and self-heals any fine cracks that develop. All of this makes it ideal for restoring buildings originally built with lime renders.
These renders are breathable, flexible, ideally suited to absorb building movement, impermeable to rainfall yet vapour permeable, reversible, easy to work with, limit the appearance of mould and fungi, and compatible with regional colours and textures.
Lime renders adhere best to traditional substrates, such as rubble stone, brick, soft stone, rammed earth, cob and hemp. They are generally not suitable for modern impermeable or cement-based surfaces unless specific preparation steps are taken. For each of our lime renders specific substrate information and preparation instructions can be found on their Product Data Sheets.
Lime render is softer, more flexible and breathable compared to cement render. While cement render can trap moisture and cause damage to historic masonry, lime render moves with the building and allows moisture to evaporate naturally.
Sika heritage lime renders come in various finishes such as float or sponge smoothed, medium scraped, brushed, spray textured and smooth spray textured. They’re available in a range of colours to suit different aesthetic requirements.
