A pourable mortar for filling holes in concrete, inside and out
Flowpatch® is an easy to mix pourable material, ideal for quick repairs to level concrete, inside or outside. Its very strong formula will harden quickly and will accept heavy traffic including forklifts only 2 hours after application.
We recommend Watco Flowpatch Deep Fill® for repairing or levelling deeper holes between 10-200mm in concrete flooring.

The substrate should be clean and free from oil or contaminants. Any loose material should be removed from the surface. If possible wire brush the surface. Edges of the repair should be cut to depth to avoid feather edging in heavy wear areas. Watco Flowpatch can be applied to damp (not wet) concrete.
Remove the bag of powder from the plastic bucket and use the empty bucket or other suitable container for mixing. To mix, add the powder to water. Use a ratio of 175–225ml of clean cold water to 1kg of powder (as a guide approx. 3.5 units of powder by volume to 1 unit of water).
Due to the short working life of the mixed product, we recommend you carry out the mixing near to the repair, not near to the water source. It’s also useful to have a bucket of water nearby, so you can quickly immerse and clean the tools after use. Put the water into the empty bucket or container and gradually add the powder stirring constantly to achieve a pourable slurry. For small quantities mix by hand using a flat bladed tool such as a spatula, and for larger quantities use a mixer fitted into a slow speed electric drill. Do not add excessive water or drying time will be extended and the performance may be impaired. As the mixture hardens quickly, pour the Flowpatch into the hole to be repaired immediately. We do not recommend re-stirring as this could potentially weaken the final repair. Do not mix more than you can use within a few minutes (5–10 minutes at 20°C). The remaining powder can be stored for future use.
When a smooth consistency is achieved, simply pour Watco Flowpatch in to the hole. If the product has been properly mixed it will self level and will need minimal trowelling. Watco Flowpatch can be applied to any depth between 5mm and 100mm, Flowpatch Deepfill can be applied to depths of 10-200mm. Repairs in lightly trafficked areas can be feather edged, but thin edges are not recommended for medium or heavily trafficked repairs.
Extensive testing is what makes us the most highly qualified paint and repair manufacturer on the market. Our screeds and repair products are tested in areas of tensile, compressive strength and flexural strength.
Our key test for Flowpatch:
Typical compressive strength at 20°C:
Day 1 | >20N/mm2 |
Day 7 | >35N/mm2 |
Day 28 | >45N/mm2 |
