KRYSTALINE Block F main features

  • Krystaline BLOCK F is a high-strength waterproof fiber-reinforced shrinkage compensating grout that is specially designed to repair leaking cracks, holes and joints.
  • Its fast setting time allows for fast repairs in cold weather and high humidity environments.
  • Krystaline BLOCK F is a fast setting, higher strength replacement for Krystaline Dry for use when rapid set is required to protect the repairs being made. It is specially formulated with our proven crystalline technology which combines chemically with water and concrete to form millions of needle-shaped crystals. These crystals grow in all directions to fill any capillary pores of the grout to block the passage of water.

KRYSTALINE Block F application

  • Krystaline BLOCK F is mixed (3.5 parts powder to 1 part clean water by volume), and applied to the prepared substrate using a trowel. Do not mix more than can be applied within 10 minutes.
  • For deep patches or overlay applications thicker than 13 mm (0.5 in.) mix Krystaline BLOCK F with clean 10 mm (0.375 in.) pea gravel (approximately 3.5 parts powder to 1.5 parts gravel to 1 part clean water by volume).
