In addition to our jewelry, we carve stones by sandblasting names,
designs, etc. We do hundreds of them each year. These are natural
stones, such as granite, fieldstone or any other stone hard enough to
hold up. They weigh from 3 lbs to over 3000 lbs. We seal and coat
them with a sealer called Litho clear. It is the same material used
by the monument industry in cemeteries. Besides coating and sealing,
it tends to bring out the color in the stone. (like when people spit
on gem rough at a show, yuk) It lasts very well outside in the
weather. It is a product of Cleveland Lithichrome Inc. Fort Scott,
Kansas, as part of their line of colors for the monument and stone
industry. It is a silicone bonding resin, which they claim is the
nearest organic material to natural silica in weathering resistance.
You spray it on, but not too heavy. You don’t want it so thick as to
peel. It dries in minutes, especially if it is a windy day. It is
available in aerosol cans but much more expensive that way. We buy
it as a liquid and spray it in a little cheap sprayer called an
"Airmite spray gun" Sells for about $35 or so. It has easily
interchanged bottles to hold different colors & solutions. The
bottles are available in glass or plastic… Plastic is best, as the
glass sometimes sticks to the sprayer if you don’t use it often. Buy
some extra bottles with the sprayer. Easy to clean, just wipe the
tube, stick the tube in solvent and give it a couple shots and you
are done. It also makes a wonderful sprayer for pripps flux. When
using the Litho clear, if you see cobwebs forming in the air, add a
little solvent to the clear,until it stops. The Litho and Airmite
sprayer are available from
