Move from recurring damp patches to a more deliberate repair plan. This polyurethane waterproof coating comes in a compact tub with its own brush for targeted work on floors, bathrooms, toilet…
Polyurethane waterproof coating for sealing leak-prone floors, walls, bathrooms, toilets, and brick surfaces.
- floor leaks
- water seepage
- bathroom moisture penetration
- toilet-area leaks
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
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.
The essentials at a glance

- 2 itemstub and application brush
How to apply it properly
- 1Inspect 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.
- 2Clean the affected area
Remove dirt, dust, loose material and flaking layers. A coating needs direct contact with a prepared substrate.
- 3Let the surface dry
Do not apply over standing water or a visibly wet surface. Wait until the prepared area is dry.
- 4Check compatibility
Tile, concrete, brick and painted surfaces can behave differently. Test a small hidden area before proceeding.
- 5Brush 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.

A more deliberate way to face seepage
- 1Where 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.
- 2A 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.
- 3Apply 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.
- 4A 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
- Close the tub
Secure the screw-top container after application.
- Follow the label
Use the product directions for brush cleaning and storage.
- Inspect the brush
Keep the wood-handled applicator clean and ready for the next targeted job.

Questions and answers
It is intended for leak-prone floors, bathroom and toilet areas, exterior walls and brick surfaces. Clean and dry the area, then test a small inconspicuous section to confirm the coating suits your specific substrate.
This is a surface waterproofing coating, not a diagnosis for failed pipes, drains, joints or hidden water sources. Find and address the source of an active leak before relying on a coating.
Coverage varies with surface porosity, application thickness and the area being repaired. Treat the 300g tub as a compact targeted-maintenance format, not a guarantee for a large wall or floor.
Those substrates differ in adhesion and preparation. Remove loose material, clean the surface, let it dry and test compatibility in a small hidden area before coating the full repair.
Yes. Apply only after cleaning and drying the prepared area. Do not brush over standing water, dirt, dust or loose material.
Caulk and tape suit particular gaps or joints, while this brush-applied coating covers a prepared surface area. The value is the compact two-item setup for targeted DIY work. A contractor is the better choice for structural damage, hidden leaks or a large waterproofing project.
