Application

Suitable for new builds and refurbishment.

Description

A reliable, economical and simple application lime-based EWI system to help improve the appearance and thermal efficiency of properties, reducing overall energy consumption. Available with coloured lime base render or brick slips for the decorative finish. 


Features and benefits


  • Tougher than cement-based renders.
  • A1 fire classification.
  • Self-cleaning properties. 
  • Traditional look and finish. 
  • Protects against algae and mould.
  • Weather resistant.
  • Over 700 render colours available.


Durability:



  • This system has an assessed anticipated lifespan in excess of thirty years.


Movement joints:



  • Where movement joints are present in the existing substrate, it is highly recommended that they are carried through the system. Please consult with the manufacturer for further details on where movement joints are required.


Design considerations:



  • Should the proposed project incorporate any unique design elements or curved elevations, please contact the manufacturer for recommendations or assistance.



INSTALLATION


Installer:

The system manufacturer, or a contractor approved by the system manufacturer. Installation shall be made strictly in accordance with Licata Building Systems Ltd instructions. Reference should be made to the project specification, method statement, drawings and all other relevant literature. Consult with LBS Ltd for latest literature and technical bulletins.



FINISHES


Primer:

Apply the Isolante LG Primer with a roller or brush to the dry base coat in an even pattern. Where possible always use the colour Primer to match the specified Topcoat finish. Allow to dry for a minimum of 12 hours. 


Licata Silicone Render:

Thin coat is a ready mixed top coat for external use, highly breathable, high water resistance and excellent mechanical strength. Silicone render provides a high resistance to algae, fungi, mould and to atmospheric agents. The careful choice of acrylic binders and silicone, ensures good durability and a gloss finish with pearlescent effect to the water drops.

Licata Silicone Render is suitable as a decorative finish in all work requiring high permeability to water vapour.


Siloxan Color:

A coating made with water-dispersed siloxane binder paste, ready for use and which can be pigmented. Siloxan Color is specifically designed for work on new or existing facades, as well as for the decorative phase of reinforced skim coating, and in LicataTherm external solid insulation. Owing to its formula, Siloxan Color provides complete protection for the facade against rain and atmospheric agents. The special additives contained in the formula guarantees excellent protection against algal and mould growth.


Brick slips:

The brick slip systems can be used across a range of different applications and substrates. Suitable for internal and external application on both new build or refurbishment projects. The brick slip systems are durable and weather-resistant with a 10-year guarantee if installed by a Licata approved applicator. A choice of acrylic or clay brick slips are available.




  • Acrylic Brick Slips: provide the traditional appearance of a brick finished building but with technology of a lightweight acrylic or mineral brick slip finish. Acrylic Brickslips are a suitable finish for external wall insulation systems used on new build or renovation of old buildings. It can also be used with timber-metal frame or modular where speed and weight are important in designs but traditional brick slips would not be recommended.
  • Licata Clay Slips: are a versatile thin brick cladding that simulates the look of traditional clay brickwork whilst providing greater insulation and more flexibility of style and application.

System performance

Thermal performance.

Preparation

Approved proprietary biocidal wash. Surfaces must be sound, free from loose material and clean.

Guidance for specification option:

Where an adhesive system is used, the surfaces must be sound, free from loose material and clean.

Where additional mechanical fixings are to be used, the substrate must be capable of sustaining the design loads.

Existing substrates that show visible signs of algae and mold will require treating with an approved proprietary biocidal wash prior to any render works.
