weberend MT 124P

A high performance, multi-coat render system, incorporating glass-fibre meshcloth on a calcium silicate panel background, and a webersil TF top coat.

Features and benefits:

• Allows previously uneven masonry substrates to be rendered, and large areas can be rendered without the need for expressed joints.

• Provides weather protection.

• A wide range of finish coat colours are available.

• BBA approved when used in conjunction with Siniat Bluclad or Knauf Aquapanel Exterior panels.

• Suitable for use in areas where the local wind-driven rain spell index is less than 100 L/m² per spell calculated in accordance with BS 8104: 1992, and in situations where traditional renders are normally specified.

Applications:

Suitable for use on new build or refurbishment projects on steel or timber framed substrates. Can be used on buildings above 18 m in England and Wales and 11 m in Scotland.

System components:

• Weber fixings as specified.

• Substrate board.

• weberend LAC (first layer, 3 mm).

• weber standard meshcloth.

• weberend LAC (second layer, 3 mm).

• weber PR310 primer.

• webersil TF textured finish.

The installation must be capable of resisting all dead loads and design live loads, including impact and wind loads, and accommodate all thermal movements without damage.

System installation is to be strictly in accordance with Saint-Gobain Weber specification. Please note that any other manufacturer's products used within the system will invalidate the guarantee, and the performance cannot be supported.

Remedial work must be completed prior to the installation of Weber render systems.

All rendering must be in accordance with the relevant recommendations of BS 13914-1: 2005, Design, Preparation and Application of External Rendering and Internal Plastering, BS 8000: Code of Practice for Plastering and Rendering. Consult manufacturer for further details.

Recommendations:

Timber or metal frame structure is required, including support rails suitable to receive render substrate boards in accordance with manufacturers recommendations, providing an in-plane and of adequate thickness for appropriate support and stiffness (limit mid span deflections L/200 and cantilever deflections to L/150. Board mid-span deflections should be limited to L/500) to receive weberend MT reinforced render system within the stated deflection limits or edge protrusions.

Prior to installation of the weberend MT system, ensure the manufacturer of the proposed approved substrate boards are contacted to obtain their fixing recommendations and ensure the boards suitability in withstanding the necessary wind load requirements for the specific project.

Cembrit PB substrate boards must not be used when the building height exceeds three storeys/ 7.2 m.
