This EWI-060 Mineral Render is sold in the 1.5mm grain size but is also available in three other grain sizes. Other grain sizes are subject to a minimum order quantity of 40 bags and an average delivery time of 5-10 working days.
Mineral Render is designed to be either applied by hand or spray machine as part of an external insulation system or on a thin-coat render-only system. The Mineral Render needs to be sealed with an approved silicone external masonry paint to ensure the product performance is consistent. Warning: without Silicone Paint application, the topcoat will not be sealed and will increase the risk of lime bloom. This render is suitable for application onto EPS and Mineral Wool external wall insulation systems. It is a fabulous finish when installing with the Mineral Wool system, as it helps to provide a completely breathable system.
Because Mineral Render comes as a dry mix, it needs combining with water before application. You can do this using a mechanical mixture or manually with a paddle mix.
The render is applied to the substrate using a notched trowel. The render should be applied at a thickness that corresponds with the chosen grain size. For example, with a grain size of 1.5mm, the render should be applied at 1.5mm thick.
Once you’ve applied the Mineral Render it should take roughly 12 hours to dry (depending upon the weather conditions). Once set, you will need to use the EWI-005 Silicone paint to seal it. You can apply our silicone paint with a spray machine, a roller or simply by using a paintbrush.
Please note: alternative grain sizes are available, subject to minimum order quantities and lead times.
Comes in powder form in a 25kg paper bag.
Store in a cool, dry place. Avoid ingress of water. Shelf life: up to 12 months from the date of manufacture.
