PROSOCO GuardEXT Concrete Sealer – Exterior High-Gloss Protective Coating (5 Gallon)

GLOSSY SEALER FOR EXTERIOR CONCRETE

Consolideck® GuardEXT is a durable, non-yellowing protective coating designed to enhance and protect exterior concrete surfaces. It significantly improves stain resistance while adding a long-lasting, glossy finish to concrete flatwork.

Ideal for steel-troweled, broomed, or stamped concrete, GuardEXT enhances the appearance of standard gray, chemically stained, integrally colored, and color-hardened concrete. It protects against spills from food and petroleum-based products while maintaining slip resistance.

Easily applied with a pump-up sprayer, GuardEXT dries quickly—typically within 60 minutes—and is ideal for use on surfaces previously treated with LS®, LS/CS®, or Blended Densifier.
