Sealing Cast Stone
The advantage in sealing your stone mantel is that it will be much easier to keep clean. For example should a child write on it with crayon or coffee or catsup be spilled on it, you can easily clean it off. Although we recommend a specific brand of sealer, any good quality clear stone sealer will work. We suggest a product made by Chemprobe Technologies, Inc. (800) 760-6776. It is called Prime-A-Pell and comes in both water based and oil based liquid. Either works well and will not change the color or texture of the stone. It is easy to use and should be applied to a clean, dry surface. Thoroughly saturate the stone almost to the point of running. Drying time is 6-8 hours.
