Product Details

TotalBoat Underwater Repair Epoxy is a must-have for your boat's emergency repair toolkit. This versatile 2-part epoxy putty stops leaks, fills voids, & patches holes in fiberglass, aluminum, steel, wood, and concrete surfaces including hulls, seawalls, decks, docks, concrete barriers and pilings, and much more. It also cures underwater, & even underway.

Cured putty resists abrasion and impacts, and prevents further metal corrosion, or wood and concrete erosion. If the repair is below the waterline, cured putty can be overcoated with TotalBoat TotalProtect or 2-Part Epoxy Primer before overcoating with antifouling paint.

Available in 2-Pint, 2-Quart, and 2-Gallon Kits for repair jobs of different sizes.

Not for use in potable water, & once cured, is not sandable.

Appears to work for pool step repair.
By Mike from SC

Verified Purchase

I used this to repair a crack (on the lower step) of my pool steps (fiberglass). So far, so good. I thought the final color was white. It's not, it's gray. Might have to apply another "coat" to totally seal the crack because I think it's still leaking. Haven't done it yet as the pool is now too cold to get in to do the final application. Will update after the final repair. appears to work as planned.

Bottom Line Yes, I would recommend to a friend
