Lythic Solutions has announced new Lythic SPD Protector, which it calls a major advance in stain protection for exposed concrete floors. Lythic SPD uses a different type of chemistry from other stain protector products: a twopart polymer combined with nano-sized colloidal silica that bonds better and shields the concrete more effectively.
“Lythic SPD Protector was exposed to very strong acid — muriatic acid — and to oil for a full 24 hours in laboratory testing,” said Lythic president David Loe in a news release. “There was no damage to the concrete. Any visible effects were easily buffed out of the Lythic SPD Protector layer. Yet, the product does not feel like a coating. It is clear, not overly glossy, and thin enough to maintain a real concrete look and feel.”
Lythic SPD Protector can be applied to almost any troweled, burnished or polished concrete. It resists staining and etching while still allowing moisture to evaporate from the slab. It is shipped as a two-part solution that gets mixed 1:1 immediately prior to use. It is rolled on with a short-nap mohair paint roller, and it dries in about two hours to approximately 1-mil thickness.
SPD is compatible with dyes and stains and is warrantied not to peel. Maintenance with the Lythic cleaning system fortifies the surface to keep SPD effective in blocking stains and etching. Lythic Solutions estimates that the material will add about 30 cents per square foot to the cost of finishing a floor.
