Hurricane CAT 4's advanced technology makes it the new industry standard of 2-part urethane sealers and provides premium surface protection. Its Armor Bond joint stabilization hardens joint sand to prevent sand washout. It provides deep color enhancement with gloss finish using T3 True Tone Technology. It has an added antifungal that protects the sealer film from mold, moss and algae. Hurricane CAT 4 is a concentrated water based film forming sealer that comes as a kit and requires mixing and dilution before use. Recommended for professional use only.

Surface Enhancement

  • Deep color enhancement with gloss finish - the extent is dependent on the surface

Joint Stabilization

  • Hardens joint sand which reduces sand washout, weeds and insect infestation

Durable Surface Protection

  • Guards against salt, mild acid, alkali and other corrosives
  • Provides stain resistance which makes cleaning and maintenance easier
  • Antifungal film protection protects sealer film from mold, moss and algae


Armor Bond

  • Creates strong joint stabilization

T3 True Tone Technology

  • Deep color enhancement with gloss finish

Durable Surface Protection

  • Ideal for high traffic areas where durability and chemical resistance is desired

Fungal Guard

  • Added antifungal protects sealer film from mold, moss and algae

Breathable, Immediate Application

  • Will not trap naturally occurring efflorescence and/or moisture
  • Can be applied on most new, clean and dry surfaces without waiting

Dry or Damp, Two Coat Application

  • Apply to dry surface for optimal joint stabilization performance
  • When sealing without joint stabilization, can be applied to a dry or damp surface with no pooling or ponding of water present
  • First coat should always be a flood coat for ideal joint stabilization - applying at 80-120 sf per gallon (of mixed and diluted product)
  • For optimal performance, apply two coats

Proprietary Two-Part Water Reducible, Clear Aliphatic Urethane Chemistry

  • Concentrated sealer packaged as a kit containing one 5 gallon pail with 4 gallons of Part A and 1 gallon of Part B. Mixing required.
  • Water dilution required providing options for desired level of sheen and strength of joint stabilization
  • Will not yellow under exposure to sunlight

Film Forming, Water Based, LOW VOC Sealer

  • Consistency of water, milky white in appearance when applied. Dries clear.

Not recommended for marble, granite, ceramic tile and polished, honed or high gloss surfaces as they do not have enough surface texture to absorb the sealer.

PERFORM A TEST IN A SMALL AREA TO VERIFY PERFORMANCE AND APPEARANCE BEFORE APPLYING. Due to the variability and physical make-up of natural stone this step is required to verify desired performance and appearance.


  • Variable speed drill, paddle mixer
  • Clean five gallon pail(s)
  • Low pressure, high volume sprayer such as an airless sprayer or hand held pump-up sprayer
  • Foam squeegee for joint stabilization
  • Slit foam roller
  • Paint shield


Sealing With Joint Stabilization

  • 80-120 square feet
  • 7.4-11.1 square meters

Sealing Only Without Joint Stabilization

  • 200-300 square feet
  • 18.6-27.9 square meters

Coverage per gallon once mixed and diluted. Single application. Actual coverage may vary depending on type, age, condition, joint size and porosity of the surface, application method and other local conditions such as temperature. For more uniform coverage, a second coat should be applied as soon as practical after the first application has visually cleared and is dry to the touch, which is usually one hour.
