The grab-and-go putty that matches texture for invisible stucco repairs.

For small cracks, holes, and surface defects in concrete or masonry, this premixed compound spares you the dust and mess of mixing powder. Straight from the pail it is a thick putty that sticks to vertical surfaces without sagging — the manufacturer says it offers superior adhesion for repairs indoor or outdoor, both vertical and horizontal.

Buyers report exactly this kind of experience: one reviewer used it to patch foundation areas that had started to crumble and crack, noting the color matched well and application was easy. A different owner said the cement-heavy texture matches existing stucco well and that the repair becomes invisible after proper drying and paint. At 1 quart, it covers roughly 3 square feet at ⅛ inch thickness, so you get enough for several moderate cracks without leftovers going bad.

Unlike the Quikrete hydraulic cement which hardens in minutes, the Akona requires full cure in 7 days before painting, meaning you need patience. Most reviewers found it straightforward, though one reported damaged containers in shipping.

The emergency plug that stops flowing water in under five minutes.

When water is actively seeping through a basement wall or around a pipe penetration, a standard patch will simply wash out. This Quikrete formula is a true hydraulic cement — it sets in 3 to 5 minutes and actually expands slightly as it hardens, locking itself into the hole. The data confirms it is built to block running water or leaks and works both above and below grade, meaning it can handle soil-side moisture pressure.

The catch is speed: you mix a small amount, knead it like clay, and press it into the leak within about a minute before it firms up. The bag weighs 10 pounds versus the Henry floor patch at 12.5 pounds, making it noticeably more portable for getting into tight crawl spaces. Use it in swimming pools, foundations, and sealing around concrete pipes — just clean the surface first and never apply on loose debris such as dirt, algae, or mildew.

Unlike the Rust-Oleum epoxy that cures in 8 hours and bonds permanently with no shrinkage, this is a true quick-fix tool. It is the right choice for stopping a problem now, but for large horizontal patches you would want a slower-setting product that gives you time to screed it flat.

The epoxy that chemically bonds to concrete and refuses to crack again.

Most patching compounds rely on mechanical grip — this Rust-Oleum formula is a true epoxy that permanently bonds concrete at the molecular level. The data says it will not shrink or crack, which is the most common failure mode for cement-based patches on garage floors or steps that endure temperature swings and foot traffic. It is a low odor, no solvent formula so you can use it indoors without fumigating the house.

Rated for use on concrete floors, walls, steps, and masonry, this 24-ounce can covers moderate repairs. Full cure takes 8 hours, so unlike the Akona stucco patch which needs 7 days, you can walk on the repair the same day you apply it. The liquid form mixes easily — a clean, elegant finish is what the maker promises, and the epoxy chemistry means it bonds to damp concrete better than standard cement patches do.

Against the Quikrete hydraulic cement (10 pounds for active leaks), this Rust-Oleum epoxy is the smarter choice for dry, structurally sound surfaces where you need the repair to last under stress — just note that at 24 ounces it is sized for smaller jobs and does not stop running water.

The gallon-sized pail that covers big floor patches without mixing a single batch.

When you have a large area — say a removed air conditioner hole in a patio floor or a section of crumbling basement slab — the last thing you want is to mix multiple small batches of powder. This Henry product comes premixed in a 1-gallon pail weighing 12.5 pounds, which is measurably heavier than the 10-pound Quikrete bag, reflecting its ready-to-use wet compound. The container measures 7.6 inches long, 7.6 inches wide, and 7.8 inches tall, so it fits on a standard bucket shelf.

It is a liquid-form, concrete-compatible compound made in the United States, designed for floor-level patching where you trowel it on and screed it flat. Unlike the Rust-Oleum epoxy (24 ounces for permanent small repairs), this gallon volume gives you the sheer quantity needed for more substantial patches without running back to the store mid-job. The included components are simply the floor patching compound — open the pail, stir, and apply.

There is no set-time or cure data in the product specs, so you should treat it as a standard cementitious patch that needs several days to fully harden. It is the right pick when your priority is coverage area and ease of use over specialty bonding or water-stopping performance.
