Skamol Lime Mortar is a breathable, natural hydraulic lime (NHL)-based bedding and finishing plaster, formulated specifically for use with SkamoWall calcium silicate boards and other mineral substrates. It provides a strong, capillary-active bond while maintaining full vapour permeability, ensuring the moisture-regulating performance of the overall system is not compromised.
Designed for use in internal retrofits, damp remediation, and breathable insulation systems, Skamol Lime Mortar is ideal for adhering calcium silicate boards to masonry and for creating a flat, slightly textured finish coat on top of the boards.
Key Benefits:
✅ Capillary Active & Vapour Permeable – Allows moisture movement through the wall system, reducing condensation risk and enabling walls to dry out.
✅ High Bond Strength – Ensures secure, long-lasting adhesion of SkamoWall boards to mineral backgrounds.
✅ Cement-Free Formulation – Made with natural hydraulic lime for compatibility with traditional and breathable construction methods.
✅ Moisture Tolerant – Can be used in damp environments without risk of trapping moisture.
✅ Easy to Work With – Excellent workability and open time, suitable for hand or machine application.
✅ Prevents Mould & Damp Issues – Helps build a breathable wall system that resists mould growth and internal moisture problems.
Applications:
🔹 Adhesive & Bedding Mortar for SkamoWall Boards – Bonds calcium silicate boards directly to masonry, blockwork, or stone.
🔹 Levelling Uneven Mineral Substrates – Used to level walls prior to installing SkamoWall or other breathable boards.
🔹 Internal Damp Proofing Systems – Ideal for retrofitting cold, damp-prone spaces such as basements or external solid walls.
🔹 Heritage & Conservation Use – Suitable for use in traditional buildings where breathability and lime compatibility are essential.
