Pool Patch Perma Repair Cement Mortar 3 lb White — Fast-Setting Underwater Waterproof Repair

Pool Patch 3 LB Perma Repair White is a fast-setting, high-strength cement mortar designed to patch and repair concrete above or below water quickly and permanently.

Whether you need to stop a leak in a swimming pool, fix a crack in a concrete holding tank, or repair pipe and structural concrete exposed to moisture, this waterproof mortar sets rapidly and bonds strongly to most cement surfaces. The chloride- and metal-free formula is engineered to resist hydrostatic pressure and freeze-thaw cycles while remaining shapable once cured. It can be mixed on-site, applied under water if necessary, and finished to match existing contours and textures.

How fast does Pool Patch set and when can it hold water?

Pool Patch is formulated for rapid setting so repairs can be completed and tested sooner than standard mortars. Its quick hardening minimizes downtime and reduces the waiting period before returning a pool or tank to service.

• Fast-setting formula designed for quick turnaround.
• Can be applied under water to stop ongoing leaks.
• Ready to shave and shape shortly after curing.
• Resists hydrostatic pressure once fully set.

Can I use this product underwater and on different concrete surfaces?

Yes — Pool Patch is specifically formulated for both above- and below-water applications and bonds to a wide range of concrete surfaces. It’s suitable for pools, concrete holding tanks, pipes, and other wet or submerged repair sites.

• Works effectively on submerged repair areas and dry patches.
• Adheres to concrete, mortar, and similar substrates.
• Chloride- and metal-free, safe for many structural environments.
• Can be colored or finished to blend with existing surfaces.

How do I mix and apply Pool Patch for best results?

Mixing is straightforward: combine the powder with clean water to the desired consistency, then apply by hand or trowel. The product’s workability lets you mold and shave it into shape before it hardens.

• Mix small batches to maintain workable time.
• Apply directly into wet or dry damage; press firmly to remove voids.
• Tool or shave surface after initial set to match contours.
• Follow safety and manufacturer mixing ratios for optimal strength.

What durability and environmental resistance can I expect?

Once cured, Pool Patch delivers a durable, waterproof repair that withstands hydrostatic pressure and freeze-thaw cycles. The formulation does not contain chlorides or metal additives, helping reduce corrosion risk in adjacent steel elements.

• Waterproof and resistant to sustained hydrostatic loads.
• Freeze-thaw stable for outdoor installations in temperate climates.
• Chloride-free to minimize corrosion concerns where metal is present.
• Can be finished to match texture and painted or colored if needed.

Who is this for? Pool Patch 3 LB Perma Repair White is aimed at pool service professionals, facility maintenance teams, contractors, and homeowner DIYers who need a fast, reliable cement repair solution for wet or submerged concrete. It’s ideal when speed, water resistance, and a strong bond are priorities — for stopping leaks, repairing damaged concrete, or restoring contours in shaded or submerged areas.
