Polyseal™ 309-A Low-VOC, Solvent-Based, Low Viscosity, Non-Yellowing, Acrylic Cure & Protect for Concrete ChemMasters’ Polyseal 309-A is a low-VOC, solvent-based, acrylic cure & protect for concrete. It is low viscosity for deeper penetration and produces a clear, non-yellowing, low gloss continuous film which effectively cures fresh concrete and protects concrete surfaces from freeze/thaw cycles, deicing chemicals, dirt and other contaminants. Uses Cure freshly placed exterior broom finish concrete to minimize crazing and shrinkage cracks. Promotes the full hydration of cement and helps to maximize concrete strength and durability. Protect existing exterior concrete from damage caused by freeze/thaw cycles, deicing chemicals, salts and other mild chemicals. Develops a clear, durable acrylic film which tenaciously bonds to the concrete surface. Advantages Allows concrete surface to develop full design strength by promoting complete hydration of cement. Low viscosity formula for maximum penetration. Highly breathable coating is less likely to whiten. Minimizes spalling due to freeze/thaw cycle exposure, hair line checking, premature cracking, dusting, and other common defects that result from improperly cured concrete. Protects concrete from deicers, salts and other mild chemicals. Compatible with most adhesives for resilient carpet & tile. Reduces maintenance costs—surfaces are easier to clean.
