Quik-Cote (1200ºF Insulating and Finishing Cement)

Quik-Cote is a mineral fiber hydraulic-setting thermal insulating and finishing cement. It is a dry mixture of mineral fiber pellets and other insulating fillers blended with hydraulic setting binders and corrosion inhibitors. When water is added, a highly plasticell nameement is formed with excellent trowelling and palming characteristics. The wet cement takes a hydraulic set in about 2 hours and, upon drying, provides a smooth, off-white, monolithic finish on the applied surface.

“Quik-Cote” is used to form a hard, monolithic finish over fibrous insulation products. It is also used to seal joints and point cracks on compound type (calcium silicate) insulation materials. It is commonly used to insulate valves, fittings and other complex shapes.


“Quik-Cote” insulates and finishes in a single operation. It is applied by trowelling or palming to a single desired thickness and should not be applied in more than one coat. A metal fabric is recommended when trowelling over fibrous materials. When applied indoors, “Quik-Cote” requires no further treatment and may be painted if desired. However, for outdoor applications, it is mandatory that a permanent protective coating be applied 24 to 48 hours after the cement is set.
