Warmshell Mesh Coat is part of the Warmshell Exterior Wall Insulation system. It is designed to be applied directly to Warmshell insulation boards, providing protection for the boards and ensuring a good surface bond for the finish coat. Once applied, it still allows the wall to breathe and provides additional protection against the weather.
Warmshell Mesh Coat is made from natural hydraulic lime combined with natural and recycled aggregates and so can be confidently used for ‘green building' or to meet specific environmental requirements.
Warmshell Mesh Coat is part of the lime green Warmshell system, a breathable external wall insulation system and requires a reinforcement mesh and a protecting top coat of Lime Green Finish WP .
Availability
20 kg paper sacks.
Coverage
One 20kg bag will cover approximately 1.8m2 at 10mm thick on a flat background.
This does not include any allowance for wastage.
Surface Preparation
Site planning must be addressed before starting work.
Ensure all board surfaces are suitably fixed, with tidy fitted edges and misses suitably filled. Board surfaces must be dry and free of any material that may impair adhesion.
Attention should be given to the correct water detailing to ensure an adequate drip from the bottom bead.
Mixing
Warmshell Mesh Coat should be mixed either with a suitable render spray machine or drill and whisk with 5-6 litres of clean water. Typical mixing time is between 5-10 minutes.
Application Guidelines
Typical Thickness: 10mm
Temperatures: above 5°C and below 30°C.
Apply Warmshell Meshcoat in 2 passes on the same day. Following the first pass embed the Warmshell 660 Render Mesh, covering the entire area, overlapping the joins by 100mm. Apply the second coat of the Warmshell Meshcoat immediately to achieve the final thickness.
Thoroughly scratch in a horizontal direction no deeper than 3mm, using a render comb to produce a key.
Curing
Prevent from drying out too rapidly. Lightly spray each coat with water if it is hot or the product is drying too quickly.
Use Lime green Finish WP as the final coat
