An extended set version of MK-6/HY™; the material can be left in the spray system for up to 5 days. Designed for concealed commercial applications, for use on steel framed structures and concrete soffits. Can be applied from one central pumping station to a building of up to 50 storeys.
The product is lightweight, economical and fast to apply. To achieve accelerated set during application (15 minutes), Monokote® Accelerator must be injected into Monokote® MK-6/HY™ ES™ at the nozzle of the spray gun.
The sprayed material bonds tightly to the substrate forming a durable surface that does not dust or flake. It has fast setting characteristics which enable it to withstand adverse weather conditions encountered during the construction phase, and can be applied when the building is not weather tight. Being gypsum based however, it is not designed for permanent exposure, or exposure to extreme weather conditions - Monokote® Z-106/HY™ or Z-146 should be used in these conditions.
