Roundtower Performance Woodlath Render is a high-performance, dry pre-mixed fibre-reinforced basecoat render, specifically formulated for use on traditional vertical and horizontal wood lath systems. It features a fast-setting formulation that significantly reduces the risk of slump, cracking, or delamination—ideal for time-sensitive heritage plastering applications.
Manufactured using only conservation-approved ingredients, including:
-
100% pure Natural Hydraulic Lime (NHL2)
-
High-purity CL90 Hydrated Lime (Lhoist)
-
Vicat Prompt Natural Cement for rapid setting

Graded natural sands
-
Natural additives and reinforcing fibres
The result is a breathable, vapour-open render that provides excellent adhesion to timber lath while offering a robust and flexible base for lime finish coats.
