Natural Hydraulic Lime render, formulated to rapidly develop strength to resit frost damage within 10 days.
Cornerstone Wintermix is a blend of Natural Hydraulic Lime and secret specially selected herbs and spices. This carefully formulated render rapidly develops enough strength to resist damage from any ice crystals forming in the render, while other work aids limit the size of any ice crystals that do form.
The strength gain is designed to take place within the first 10 days of curing, once it has reached this point Wintermix performs and behaves in the same manner as a standard NHL3.5 render.
Not suitable for cob or soft/friable masonry.
