The Heritage Lime Harling is a substrate preparation layer which is ideal for use on heritage restoration properties. The Lime Harling essentially creates a roughcast effect, which provides a mechanical key for further materials to bond to. Due to the presence of lime within the material, the Heritage Lime Harling is completely vapour-permeable and offers a strong adhesion to substrates with a high salt content.
The Heritage Lime Harling is a watery slurry which is intended for machine or manual application on external walls. The product should create a rough surface to aid the adhesion of further lime-based materials. This product is suitable for application onto substrates with a high level of absorption, or those that have been previously painted.
