This silicone-based, brush-on waterproof seal soaks into cracks and dries into a clear, flexible film that moves with the surface instead of peeling away.
StormGuard goes on in one thick coat with the included brush, avoiding the need to tear out drywall or hire a pro. The cured film remains flexible as the surface shifts, keeping water out.
Spray sealants can leave edge gaps and peel when moisture hits, while rigid caulk often cracks with temperature changes. StormGuard is brushed on to form a thick, continuous coat that grips into the crack and stays bonded as conditions change.
It cures clear and invisible on wood, metal, tile, and stone, so the seal blends with the surface rather than leaving a patch behind.
The film stays rubbery, bending with the surface instead of cracking as the area expands or contracts. When you brush StormGuard onto the crack, it self-levels into a smooth, continuous layer, touch dry in about 30 minutes and fully sealed within 24 hours.
Because it cures as a single flexible sheet rather than a stiff crust, there’s no hairline gap for moisture to exploit. It stays bonded and flexible through summer heat and winter freeze, keeping the area dry.
Where to apply: it bonds to wood, metal, tile, stone, masonry, and brick—indoors or outdoors. Use on bathroom windows, pipe joints under sinks, shower grout, roof flashing, basement corners, and anywhere moisture tends to seep in.
| What Actually Keeps the Leak Out | StormGuard | Others |
|---|---|---|
| Full, Continuous Coat | ✅ Thick brush coat fills the crack with no thin spots | ❌ Aerosol mist misses edges and corners |
| Stays Flexible, Won't Peel | ✅ Rubbery film bends with the surface | ❌ Cracks or peels once the surface moves |
| Invisible Finish | ✅ Dries clear on tile, wood, metal, stone | ❌ Leaves a visible patch or white smear |
What’s Included: Jar of StormGuard agent plus a brush and spreader—everything you need to apply it.
- Find the leak and wipe the area clean and dry. StormGuard bonds to wood, metal, tile, stone, and masonry—so the same jar handles the window, the pipe joint, and the basement corner.
- Brush a thick, even coat over the crack with the included brush, and smooth the edges with the spreader. It self-levels into a clear film—touch dry in about 30 minutes, fully sealed in 24 hours.
- Let it cure and forget about it. The flexible film bends with the surface and stays invisible—no cracks, no peeling, no stain creeping back next season.
