Hurricane CAT 4 – Durable 2-Part Urethane Sealer with Joint Stabilization

Hurricane CAT 4 sets the new standard for 2-part urethane sealers, delivering premium surface protection and deep color enhancement with a gloss finish. Built with Armor Bond joint stabilization, it locks in joint sand to prevent washout while reducing weeds and insect intrusion.

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 the first application has visually cleared and is dry to the touch (usually after 1 hour).

Important

Always test in a small area before full application—especially on natural stone—to confirm desired appearance and performance.
