Hi, Welcome to factory !
Garden ornaments such as decorative wall plaques or small statues that are carved from genuine sandstone can be expensive to buy. A less costly alternative is to make your own sandstone castings using ordinary builders sand, or even play sand. When the sand is mixed with epoxy resin, which is readily available from craft stores or DIY stores, the resulting material looks very realistic. When using a heavy material such as sand in a mold, make sure the mold is sturdy since a thin latex or silicone mold will not be strong enough to support the weight of the sand and will distort.Free quote
