How long does it take for my mantle to be made and shipped out?
We typically require 3-4 weeks of lead time to manufacture and ship a standard mantle.
What is the material of the mantle and how much does it weigh?
Indoor mantles are made from our own proprietary mix of gypsum cement, and marble aggregate. It is substantially stronger than most gypsum cements.
Outdoor mantles are made from a new type of fiberglass reinforced cement, cast to imitate travertine marble.
Our mantles typically weigh only 200-500 pounds, and can be installed by a crew of two people in half the time of a carved stone mantel.
Are you a green manufacturer?
Our special gypsum Mix includes as much as 15% recycled byproduct, which adds substantially to its strength.
Our new exterior cement uses ½ the manufacturing energy of regular cement, while developing 1-1/2 to 2 times the compressive strength. This allows us to develop stronger lighter products which saves shipping fuel.
Our marble aggregate comes from Marble, Colorado just north of Aspen, about 150 miles from Denver.
Our cement comes from Southard,Oklahoma, 700 miles southeast.
We recycle 75% of our rinse water.
Are your mantles fireproof?
Yes, they are 100% fireproof, with zero contribution to flame spread measured by ASTM standard E136-94A.
Can your mantles be repaired if damaged?
Yes, Cast products were historically difficult to repair, but we developed products for just that situation. Many small scratches can be sanded away with 80-220 grit sandpaper much like marble. We always include a repair kit with instructions for minor chips and screw holes, including a blemish hiding compound. For larger problems we can send a repair professional, or talk you through it.
How do I clean my mantle?
Most household bathroom or kitchen cleaners work fine. Avoid oily cleaners meant for wood. Always test any cleaner on an unobtrusive area first.
How do I remove stains?
First identify the stain.
A. Coffee Tea, or various food and drink stains: Mr. Clean is our first choice for stains. Followed by Bleach (for coffee stains), and finally Bar Keepers friend contains oxalic acid and must be used with caution, but as a last resort.
B. Red wine, Grape juice or acidic red/purple stains. These are tough, and we highly recommend that you keep these drinks away from your mantle. Clean up any spills immediately, as these acids can eat into the surface. Periodically seal your mantel. (see below)
Can I set potted plants on my hearth, or shelf?
Never place a potted plant on your hearth or shelf. In Colorado especially, the acidic soils can leave a ring in the surface.
Should I apply a sealer to my mantle?
Yes, it’s a good idea to seal the hearth and top of the shelf especially every few years. We recommend OKON W-1 or W-2 acrylic-siloxane penetrating sealer, by Zinnser. After applying the product, test it by sprinkling water on the surface. If it soaks in, apply a second time, or until the water sits on top. What we like about this product is that it doesn’t affect the surface appearance as much as other sealers we’ve tried, and it’s very effective.
