HOLD OUT

Description

HOLD OUT- is a reactive, penetrating catalyzed potassium siliconate solution that fuses within porous substrates of concrete, brick, stone, and mortar to combat freeze/thaw damage, scaling and spalling, and limit penetration of stains and damaging impurities such as oil, gas, grease, and salt. Hold Out™ is breathable with minimal impact to traction coefficient. Hold Out creates a cross-linked insoluble methyl-silicone internal membrane that will wear away only if the substrate itself wears away below sealer penetration.
