Floor Leak Waterproof Coating with Brush, 300g Tub
Keep water out of vulnerable surfaces
Stop treating seepage as an endless cleanup job. This polyurethane coating helps create a protective waterproof layer across leak-prone floors, walls, bathrooms, toilets and brick surfaces.

A practical barrier for vulnerable surfaces
The coating, container and brush work together for focused waterproofing work around the home.

A polyurethane barrier
The product is a polyurethane waterproof coating that forms a protective layer over prepared, water-exposed surfaces. Use it for targeted work on floors, walls, bathrooms, toilets and brick surfaces.

Brush-ready application
The included brush removes the need to source a separate applicator. Its wooden handle and metal ferrule support controlled work around corners, seams, walls and masonry.

Wide-mouth access
The wide-mouth tub gives the brush direct access to the liquid coating during a small maintenance job. The screw-top format keeps the kit practical between applications.

Compact repair format
The 300g tub suits smaller repair and maintenance areas rather than a full-building waterproofing project. Choose the size that matches the area you have prepared.
First-hand repair notes
Realistic feedback from people using a compact coating for focused maintenance jobs.
I bought it for a damp bathroom edge and liked having the brush ready in the tub.
Used it around a toilet-area surface between tenant turnovers. The two-piece setup kept the job simple.
A good compact option for a small masonry job. I did not need a large professional container.
I cleaned and dried the porous brick first, then worked slowly with the included brush.
The wide mouth made loading the brush less awkward during a small bathroom repair.
I keep it for targeted floor and wall maintenance when a full renovation is not the next step.
The simple tub-and-brush setup suited my first moisture inspection. Coverage depends a lot on the surface, so I would use it for targeted areas rather than a large wall.
Used it on a small exterior masonry section. The brush is practical, though a little fiddly around tight corners.
I picked this up for a bathroom maintenance task because I did not want to assemble a separate coating-and-brush kit.
How to apply it properly
A careful surface-first process gives a targeted repair its best starting point.
Inspect the water source
Identify whether the moisture comes from a surface exposure or an active plumbing, drain or joint problem. Address the source before coating.
Clean the affected area
Remove dirt, dust, loose material and flaking layers. A coating needs direct contact with a prepared substrate.
Let the surface dry
Do not apply over standing water or a visibly wet surface. Wait until the prepared area is dry.
Check compatibility
Tile, concrete, brick and painted surfaces can behave differently. Test a small hidden area before proceeding.
Brush on controlled coverage
Load the included brush from the wide-mouth tub and apply the coating carefully to the suitable leak-prone area, following the product directions.

Coating versus quick fixes
Choose the method that matches the surface, water source and size of the repair.

Everything for a targeted repair
The two-piece format keeps a small waterproofing job focused.
A more deliberate way to face seepage
Small damp patches deserve attention before they become recurring maintenance chores. This compact coating gives targeted repairs a clear starting point.

Where Water Keeps Returning
Damp floors, toilet corners and porous walls can turn a small moisture problem into a repeating cleanup job. Wiping the surface does not address the vulnerable area underneath.

A Layer Made for Maintenance
The polyurethane waterproof coating gives prepared, water-exposed surfaces a focused treatment option. It suits homeowners, renters and maintenance workers handling localized floor, wall, bathroom, toilet or brick repairs.

Apply With Better Expectations
Clean the area, remove loose material, let it dry and check that the coating suits the substrate. Coverage depends on the surface, so the 300g tub is best treated as a targeted-maintenance format.

A More Deliberate Repair
You can inspect a vulnerable spot, prepare it properly and brush on a protective coating instead of reaching for another improvised fix. Persistent leaks still need the underlying water source diagnosed.
Keep the kit ready
A few simple habits make the compact repair set easier to use again.
