Lythic Day-1 is a troweling aid and curing agent that extends finishing time and reduces surface drying without weakening the slab or adding excessive water. It retains water during curing, with performance to equal a membrane-forming curing compound, even though there is no membrane, film, or residue left to remove. It becomes a permanent part of the slab that strengthens the surface and makes it water-repellant. Lythic Solutions, Inc. 360-694-5347. www.lythic.net [WOC Booth S12747]
