Brickwork Render System

Brickwork Substrate Silicone or Acrylic Finish
System Build-Up

Layer-by-layer system specification

The Brickwork Render System is Licata's standard render specification for direct application over brick masonry substrates. The system is flexible: an optional substrate primer and levelling coat are available where the brickwork requires it, and the finish coat can be specified as either Siloxan Color silicone render or Lerici acrylic render depending on performance and budget requirements.

Raso W160 or Raso Top 800 can be used as the basecoat depending on substrate condition and project specification. Both are polymer-modified and compatible with fibreglass mesh reinforcement and the Isolante LG primer system.

System Layers

Products

1
Layer 1: Substrate
Brickwork
Existing or new brick masonry substrate. Must be structurally sound, clean and free from contamination, organic growth, loose mortar and efflorescence. Rake out any defective pointing and repoint before rendering.
Layer 2: Substrate Primer Optional
Acril Primer or Aggrappante LG
A substrate primer is recommended on highly absorbent or variable brickwork to even out suction and improve adhesion of the basecoat. Acril Primer is an acrylic bonding primer for smooth or low-absorption surfaces. Aggrappante LG is a spatterdash bonding agent for dense or glazed brick where mechanical adhesion is required.

Layer 2: Levelling Coat Optional
Licacem 200
Where the brickwork face is uneven, particularly on older or handmade brick, a levelling coat of Licacem 200 can be applied to provide a flat, uniform surface for the basecoat. Apply to areas requiring build-up and allow to cure before the basecoat is applied.

Layer 3: Basecoat
Raso W160 or Raso Top 800
Raso W160 is a lightweight polymer-modified basecoat, lower in density and easier to work than standard basecoats, suited to less demanding substrates. Raso Top 800 is a higher-performance polymer-modified basecoat and adhesive for more demanding conditions or thicker build applications. Apply in one or more coats to the required thickness and embed the fibreglass mesh whilst still fresh.

Layer 4: Reinforcement
Fibreglass Mesh
Alkali-resistant fibreglass reinforcement mesh, embedded into the fresh basecoat. Minimum 100mm laps at all joints. Apply additional diagonal mesh at all openings and corners to prevent cracking.

5
Layer 5: Topcoat Primer
Isolante LG
Silicone-based topcoat primer, applied over the fully cured basecoat to consolidate the surface and provide uniform, controlled absorption for the render finish. Available in white and tintable to match the render colour, reducing the number of finish coats required.

Layer 6: Render Finish
Siloxan Color or Lerici
Siloxan Color is a silicone render finish: highly water-repellent, breathable, anti-mould and available in a wide colour range. Preferred for exposed elevations and where long-term performance is the priority. Lerici is an acrylic render finish, a cost-effective and durable decorative option available in a wide range of textures and colours.
