Enviromin mineral finish
Direct fix to a suitable masonry wall and can be used with either mineral wool insulation, expanded polystyrene or phenolic insulation depending on the requirements.
Suitable for installation on external solid masonry substrate walls (where masonry includes clay and calcium silicate bricks, concrete blocks and natural and reconstituted stone blocks, concrete or no-fines concrete).
Suitable for use on existing or new, residential and non-residential high-rise buildings up to and over 18 m in height in the United Kingdom (UK).
The System can be designed for a 30 or 60-year service-life durability as required.
A mechanically fixed external wall insulation (EWI) Mineral wool, EPS and Phenolic options available. EPS and Phenolic systems are Euro classification B-s1, d0.
MW insulation in slab form is bonded and mechanically fixed through the glass-fibre reinforced basecoat layer, into the solid masonry wall. The System is completed with one of two available render finishes. Also available with a flexible brick slip finish to re-create a brick appearance with lightweight slips.
Must include a minimum of one stainless steel fixing per/m² of MW insulation, or per insulation batt, whichever is the lesser, fixed through the reinforcing mesh and MW insulation, in addition to the other MW insulation fasteners normally specified.
The System is classified as Euroclass A2-s1, d0 according to BS EN 13501-1.

Preparation | Prior to commencement of work the supporting wall must be finished and free from protrusions and uneven jointing.Guidance for specification option: Prior to commencement of work the supporting wall must be finished and free from protrusions and uneven jointing. The flatness of substrate surfaces must be checked using a straight-edge tool spanning the storey height. Irregularities greater than 10 mm in a 1 m² area, must be made good. Longer fixings may be required in areas that have been levelled to ensure the correct embedment depth is achieved. |

Application | Finish coat.Guidance for specification option: Primer is optional dependent on finish specified; consult manufacturer for details. EnviroSil Top Coat The render should be stirred, and a small amount of water may be added (to a maximum of 2 % by volume) if required. Apply onto the primer coat with a stainless-steel smoothing trowel and float to a thickness of 1.0 - 3.0 mm (thickness determined by grain size) and rub with a plastic float in a circular motion to create the required finish within 5 - 15 minutes after application. A straight edge can be used to help ensure a flat surface, and wet sponges, wooden boards or similar tools can be used to create the desired textured finish. Wipe clean all exposed nosing, cills etc. EnviroMin Mineral Render Top Coat. The render is mixed with between 6.5 to 7.0 litres of cold water. Apply onto the base coat with a stainless-steel smoothing trowel and float to a thickness of 1.0 - 3.0 mm (thickness determined by grain size) and rub with a plastic float in a circular motion to create the required finish within 5 - 15 minutes after application. |
