Masonry Mineral Wool Mineral Brick Slips
System Build-Up

Layer-by-layer system specification

This is Licata's EWI system combining non-combustible mineral wool insulation with a mineral brick slip finish, the highest-specification option in the masonry EWI range. Mineral wool delivers enhanced fire performance, while mineral brick slips provide a lightweight, consistent brick appearance with low maintenance requirements. Licata supplies the complete system from a single source.

Raso Top 800 is used as both the insulation adhesive and the reinforced basecoat, encapsulating the fibreglass mesh reinforcement. A dedicated mineral brick slip adhesive bonds the slips directly to the cured basecoat.

System Layers

Products

1
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 should be repaired before insulation is fixed.
2
Layer 2: Insulation Adhesive
Raso Top 800
Polymer-modified cementitious adhesive, 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.

3
Layer 3: Insulation
Mineral Wool Insulation Board
Non-combustible mineral wool insulation boards, thickness specified by U-value calculation. Fixed using Raso Top 800 adhesive and mechanically secured with EWI fixings. Boards staggered at joints with no gaps.
View product
4
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. Must be flush with or counter-sunk below the board face.
5
Layer 5: Basecoat
Raso Top 800
Polymer-modified basecoat, applied over the insulation boards in two passes to encapsulate the fibreglass mesh. First pass embeds the mesh, second pass covers it fully. Minimum total thickness 4 to 6mm. Allow to cure fully before applying brick slip adhesive.

6
Layer 6: Reinforcement
Fibreglass Mesh
Alkali-resistant fibreglass reinforcement mesh, embedded into the first pass of Raso Top 800 basecoat. Minimum 100mm laps at all joints. Additional diagonal mesh at all openings to prevent corner cracking.

7
Layer 7: Brick Slip Adhesive
Mineral Brick Slip Adhesive
Dedicated mineral brick slip adhesive, bonding the mineral brick slips to the cured Raso Top 800 basecoat. Formulated specifically for use with mineral brick slip systems on EWI substrates.
8
Layer 8: Finish
Mineral Brick Slips
Mineral brick slips are lightweight, low-maintenance brick-faced panels bonded to the EWI basecoat. Consistent colour and texture across the elevation. Available in a range of brick tones. Joints pointed on completion.

Benefits

Benefits of Masonry Mineral Wool Mineral Brick Slips

Non-Combustible Insulation

Mineral wool is non-combustible, delivering enhanced fire performance and meeting the requirements of projects where A2 or better reaction to fire is specified.

Brick Appearance

Mineral brick slips deliver a consistent, low-maintenance brick appearance, with uniform colour and texture across the full elevation.

Lightweight Finish

Mineral brick slips are significantly lighter than clay brick slips, reducing dead load on the EWI system and simplifying handling and installation on site.

Single Source Supply

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