Concria™ Guard (Only in the USA)

High-Performance Sealer for fast power trowel burnishing

Concria GUARD is a patented, high-performance, acrylic copolymer sealer for use on polished concrete and all uncoated cementitious surfaces. Our patented formulation forms a shiny, protective film on concrete and natural stone, improving cleanability and chemical resistance of polished concrete.

Concria GUARD sealer is easy to apply, quick drying, nonflammable, UV stable, and it eliminates the need for floor waxes, liquid polishes, and conventional resin-based coatings. The sealer can also be burnished with ride-on trowels, making it much faster to apply than a sealer that requires the use of a high-speed burnisher.

Application procedure

You can use Concria GUARD copolymer sealer on both new and old polished concrete and dry-shake floors. Polished concrete floors also require Concria HARD lithium densifier.

Maintenance tips

  • Sweep the floor daily with a microfiber pad or dry dust mop
  • Do NOT use acidic cleaners (with pH below 7) to maintain treated floors
  • For peak performance and results, clean the floor daily by auto scrubber with diamond impregnated pads (DIP)

Though ConcriaTM GUARD will improve your floor’s stain resistant qualities, some acidic or oil products may leave a stain if left on the surface. Clean up all spills promptly to minimize any possible damage.
