Licata Ecopure Bio

Masonry Mineral Wool Silicone Render

System Build-Up

Layer-by-layer system specification

Licata Ecopure Bio is an external wall insulation system for brick or block masonry substrates, combining non-combustible mineral wool insulation with products from Licata's Bio range. It is designed for projects where the environmental profile of the build-up matters as much as its thermal and fire performance. Licata supplies the complete system from a single source.

Raso Top Bio is used as both the insulation adhesive and the reinforced basecoat, encapsulating a heavy-duty 330g/m² fibreglass mesh. Siloxan Primer and Siloxan silicone render complete the system, delivering a water-repellent, breathable, low-maintenance decorative finish.

System Layers

Products

Layer 1: Substrate

Brick or Block Masonry

Existing or new masonry substrate in brick or block. Must be structurally sound, clean and free from contamination, organic growth, loose render or paint. Any defects or voids in the masonry should be repaired before insulation is fixed.

Layer 2: Insulation Adhesive

Raso Top Bio

Adhesive from Licata's Bio range, applied to the rear of the mineral wool board using the dot-and-dab or full-bed method to bond the insulation to the masonry substrate. Achieves the high adhesion values required for EWI systems in exposed conditions.

Layer 3: Insulation

Mineral Wool Insulation Board

Non-combustible mineral wool insulation boards, thickness specified by U-value calculation. Fixed to the masonry using Raso Top Bio adhesive and mechanically secured with EWI fixings. Boards staggered at joints and tightly butted with no gaps.

Layer 4: Mechanical Fix

Insulation Fixing

Mechanical EWI fixings, installed through the insulation board into the masonry substrate. Fixing type and density determined by pull-out testing and wind load calculations for the project. Fixings must be flush with or counter-sunk below the board face.

Layer 5: Basecoat

Raso Top Bio

Raso Top Bio basecoat, applied over the insulation boards in two passes to encapsulate the fibreglass mesh reinforcement. The first pass embeds the mesh, the second pass covers it fully. Allow to cure fully before priming.

Layer 6: Reinforcement

Fibreglass Mesh 330g/m²

Heavy-duty 330g/m² alkali-resistant fibreglass reinforcement mesh, embedded into the first pass of Raso Top Bio basecoat for enhanced impact resistance. Laps must be a minimum of 100mm at all joints. Additional mesh should be applied diagonally at all openings to prevent corner cracking.

Layer 7: Primer

Siloxan Primer

Siloxane-based primer, applied over the fully cured Raso Top Bio basecoat to consolidate the surface and provide uniform, controlled absorption for the silicone render finish.

Layer 8: Render Finish

Siloxan Silicone Render

Silicone render finish, applied over the Siloxan Primer. Highly water-repellent with excellent vapour permeability, anti-mould and algae-resistant additives and low dirt pick-up. Available in a wide colour range.

Benefits

Benefits of Licata Ecopure Bio

Bio Range Formulation

Built around Raso Top Bio from Licata's Bio range, for projects where the environmental profile of the specified materials is a priority alongside performance.

Non-Combustible Insulation

Mineral wool insulation is non-combustible, providing enhanced fire performance compared to EPS-based systems.

Breathable and Weatherproof

The Siloxan silicone render finish is highly water-repellent yet maintains high vapour permeability, keeping rain out whilst allowing moisture to escape from the wall.

Single Source Supply

Licata supplies the complete system of insulation, fixings, mesh, adhesive, basecoat, primer and render, simplifying procurement and ensuring full system compatibility.
