Hold Out

Hold Out is a reactive, penetrating catalyzed potassium siliconate solution concrete water repellent that fuses within porous substrates of concrete, brick, stone, and mortar. It combats freeze/thaw damage, scaling & spalling, and limits the penetration of salt and stains like oil, gas and grease. Hold Out is breathable with minimal impact to traction coefficient. Hold Out creates a very durable cross-linked insoluble methyl-silicone internal membrane.

• Can be applied to concrete same day after bleed water is gone

• Does not change the color of the concrete

• Deeply penetrates porous surfaces, it provides excellent water repellency, while allowing surface to breathe.

• Almost zero impact to traction coefficient.
