LesCoat is a concrete stain block with a surprise ending — it's peelable.
Les Stever, the inventor of LesCoat and owner of Stenciled Concrete Stains in Lansdale, Pa., says he was looking for something that blocked the migration of stains and came up with this product. "It is like a peelable caulk that blocks stain migration on concrete, and is also sandblast-proof," he says. "It is the same as regular caulk; the only difference is you can peel it off when finished."
Since 2002, contractors and homeowners have been sponging LesCoat on over stencils or drawing it straight onto the concrete with various techniques, such as using a squeeze bottle, to create decorative effects. Stever says it is so simple, it is almost foolproof. "If you make a mistake, just peel it away. Try that with scoring."
LesCoat is a proprietary, water-based, gel material. After it is applied and allowed at least 24 hours to dry, it is sandblast-resistant and impervious to acid- or water-based stains as well as water-based or solvent-based sealers. It can be peeled completely away after the stain or dye sets, or in stages to allow for the use of multiple color applications to give an infinite array of designs and effects.
As far as Stever knows, there is no other product like it. "There is no other way to get this effect. It is a method in itself," he says.
