Stop letting rain ruin your paver installation.

This 40 lb bucket is the professional hardscape contractor's secret weapon for beating unpredictable weather, tight project schedules, and last-minute installation headaches.

Why Choose Techniseal STORM Over Traditional Polymeric Sand?
Traditional polymeric sand fails the moment the weather turns. One unexpected rain shower can ruin an entire day's work, wash out joints, trigger haze, and force costly do-overs. Techniseal STORM changes everything. This pre-mixed, wet weather paver jointing compound installs in rain, over damp pavers, in high humidity, and during changing forecasts — no tarping, no delays, no rescheduling, no wasted product.
STORM is the only true multi-weather polymeric sand alternative engineered to cure in wet or dry conditions, deliver a permeable joint that drains properly, and stay flexible through harsh freeze/thaw cycles, soil movement, and extreme Northeast winters. It's the professional jointing compound trusted for patios, walkways, pool decks, flagstone installations, porcelain tile pavers, and large-format slab hardscape projects.
