Heat Curing Process for RUTLAND Indoor Cements

To properly heat cure your RUTLAND cement product indoors, we recommend following the steps below.

Begin by starting and maintaining a kindling, or small fire, and allow it to burn for one hour. After that hour has passed, gradually build the small fire up to a roaring fire (at least 500°F) and maintain the larger fire for an additional hour.The entire process should take approximately 2 ½ hours.

If a heat cure is required and is not performed within 21 days of application, the cement or mortar will become brittle, fragile, and chalky. It will eventually lose all adhesion, falling out over time. For step-by-step instructions, check out our how-to video below.
