SILICONE RENDER

Silicone render is the breathable, flexible, lightly textured and coloured finish that decorates and protects external wall insulation (EWI) and thin coat render systems.

The base coat, mesh, primer and silicone finish components within EWI systems, that are used to cover the insulation, can also be applied directly onto masonry, render carrier board and ICF construction. This is why the installation of these elements without insulation is often referred to as “silicone render only”.

The way in which the silicone finish is manufactured means it can be mixed to closely match all of our Monocouche XF colours, RAL codes and even some well know paint manufactures colour titles.

We have worked in partnership with several industry leading silicone render system manufacturers for many years and are certified to offer their systems on a fully warrantied turnkey supply and install basis.

EXAMPLES OF SILICONE RENDER

SILICONE RENDER (ONLY) A BASIC GUIDE

MASONRY CONSTRUCTION

The benefits of high performance silicone render can be enjoyed on projects constructed entirely of masonry.

Silicone render can also be installed where masonry panels are present within a scheme that has insulated or render boarded surfaces also to achieve a consistent finish throughout.

A high polymer base coat is applied at 10mm over the masonry and when suitably dry the base coat is primed in preparation for the final through colour decorative silicone layer.
Alkali resistant mesh is imbedded between the two base coat layers whilst wet.
10mm PVCu are installed to encapsulate the base coats and give definition to the finished product.

Silicone render onto stable masonry system thickness guidance:
10mm of base coat + 1mm – 2mm of silicone finish = approx. 12mm.

TIMBER & STEEL FRAME CONSTRUCTION

In timber frame, steel frame and SIPS construction, where the insulation is achieved within the framework structure or internally, the silicone render system is installed onto the enclosing render carrier board.

High polymer base coat is applied in two coats to the render carrier board and when suitably dry the base coat is primed in preparation for the final through colour decorative silicone layer.
Alkali resistant mesh is imbedded between the two base coat layers whilst wet.
PVCu and mesh beads are installed to encapsulate the base coats and give definition to the finished product.
Silicone render onto render carrier board system thickness guidance:
6mm of base coat + 1mm – 2mm of silicone finish = approx. 8mm + thickness of render carrier board.

A system using a 12mm render carrier board would total approximately 20mm in thickness from the outer face of the battening.

The required battening configuration onto which the render carrier board is fixed may differ between system manufacturers and building warranty providers with some requesting a single vertical batten and others both vertical and horizontal. We strongly advise seeking confirmation of the required battening layout from your warranty provider to ensure that building warranty guidelines will be met.

If you require a warranty for the total render carrier board and silicone render system all components including the render carrier board, fixings and the silicone render system should be purchased from the same manufacturer and as Importantly installed by a contractor who is registered and certified by them.

EXISTING PAINTED MASONRY OR RENDER

We offer a warrantied specification for silicone render onto existing and stable painted masonry or render.

After review, if the painted substrate is deemed to be suitable this method of install would remove the need to remove the paint or render therefore saving time, cost and intrusion.

To achieve warranty, we would have to prepare the substrate by methods such as anti-fungal cleaning, scoring, priming and or installing mechanical fixings to ensure sufficient key and connection with the masonry behind.

We may also need to remove the opening reveals and heads to ensure the new system meets with the existing window and door frames correctly.

Silicone render onto existing painted masonry or render system thickness guidance:
10mm of base coat + 1mm – 2mm of silicone finish = approx. 12mm.

INSULATED CONCRETE FORMWORK (ICF)

In ICF construction the silicone render is installed directly onto the ICF structure.

High polymer base coat is applied in two coats to the ICF structure and when suitably dry the base coat is primed in preparation for the final through colour decorative silicone layer.
Alkali resistant mesh is imbedded between the two base coat layers whilst wet.
10mm PVCu are installed to encapsulate the base coats and give definition to the finished product.

Silicone render onto ICF construction thickness guidance:
10mm of base coat + 1mm – 2mm of silicone finish = approx. 12mm.

Monocouche XF

Best Practice Guide

MonoBase XF applied to 4mm thickness onto masonry

MonoMesh XF imbedded into entire MonoBase XF layer

Monocouche XF finished flush with 15mm UPVC beads

Total system thickness 15mm + depth of bead bedding

MonoMesh XF alkali resistant mesh is imbedded into the Monocouche XF or MonoBase XF at material junctions and surrounding openings to absorb stress.

In the case of XF Best Practice we advise that MonoMesh XF should be overlapped 100mm at the edges.

Diagonal strips of MonoMesh XF (stress patches) are added to further reinforce across the corners of openings.

SUBSTRATE PREPARATION & INSTALLATION PARAMETERS

Masonry substrates should be stable, clean, suitably dry and free from dust and loose material
Newly constructed masonry should be allowed to dry sufficiently before render system install
Mortar jointing should be flushed level with the surrounding masonry
Levelling preparation should be carried out with MonoBase XF
Direct contact with the masonry should be made without contamination
Wiring and pipework for external accessories should be chased into the masonry
Do not apply in temperatures below 5c, above 30c and immediately before a frost or heavy rain
Do not apply to gypsum plaster or painted surfaces

MATERIAL COVERAGE GUIDANCE

A 25kg bag of Monocouche XF will cover up to 1m² at 15mm thickness

A 25kg bag of MonoBase XF will cover 4m² – 5m² at 4mm thickness

A full pallet of Monocouche XF or MonoBase XF contains 40 x 25kg bags (1000 KG).

MonoMesh XF is supplied in 50 m² roll (1m x 50m) coverage is 45m2 per roll allowing for 100mm overlaps

Total System Thickness: 15mm + depth of bead bedding

The above information is supplied as a guide; material usage is completely dependent on specific substrate type and condition, and should be confirmed at site.

MONOCOUCHE XF & RENDER CARRIER BOARD

Monocouche XF will bond successfully to render carrier boards with the support of MonoBase XF and MonoMesh XF. However, there is an unknown risk of movement within the supporting timber or steel framework, that may cause deflection, forcing the render to crack. For this reason, Monocouche XF is not guaranteed in these applications and a thin coat silicone render should be considered.

UPVC PROFILE BEADING:

15mm UPVC angle/corner beads are installed to rendered corners giving definition and providing protection against impact.

15mm UPVC drip/bell beads are installed at the base of elevations to force water to fall away from the finishes below and protect against rising damp and capillary action.

15mm UPVC stop beads are installed to give neat and level termination at elevation boundaries and material junctions.

15mm UPVC expansion/movement beads are installed over expansion joints within the masonry substrate.
