Installation Instructions
Preparation of Area for Application
Brush off and remove any loose masonry or soot from the surface. Pre-dampening is not needed however some prefer to do so.
Pre-installation Tips
- Use only containers and mixing equipment that are free from other masonry or other residue.
- Clean plastic or metal containers work best. Dry mix desired quantity thoroughly first.
- Approx. Ten lbs. at a time is a good quantity to start.
- Use only clean, cold water. Hot water will quicken set time.
- For trowel/parge application add 6-8 cups of water for ten lbs. of Chamber Safe. Mix very thoroughly. For cast application add 8-10 cups of water for ten lbs. of Chamber Safe.
- Mix very thoroughly.
- Cast into form configured as may be needed.
- Quantity of water may be slightly adjusted by the installer to their preference.
Application
- Apply with desired hand tool (parge or trowel) over the desired area one to two lbs. (per trowel) at a time.
- Compress to assure no voids in the area of application.
- Apply first coating ½” to 1 ½” thick. If another coat is desired apply ¼” to ½” thick to obtain desired total thickness. If second coat is to be applied rough up or score the surface of the
first coat. This allows for superior bonding of the second coat application. - Allow first coat to air dry before application of the second coat.
