Before using Resincoat Fast Cure Epoxy Crack Repair Filler, we recommend the area be thoroughly vacuumed to remove any loose material or existing debris which could cause the epoxy formula to set unevenly. If the crack is large enough, a wire brush should be used to clean out the area. For a clean application, angle grind the crack to achieve a better look. If you suspect the crack runs the complete depth of the epoxy add some kiln-dried silica sand to the bottom of the crack to create a bund.



We advise when applying this product the ambient temperature is at least 7°C.

1. Pour 100% of Part B into the Resincoat Epoxy Crack Repair Filler Part A tin. Thoroughly mix using a drill and paddle for a minimum of 90 seconds, until a uniform colour and texture is achieved.

2. Pour the formula into the crack, distributing it slowly and evenly as you go until the crack is filled.

3. Once filled, allow for the epoxy to fully cure.


PLEASE NOTE: The pot life of this product is 15 minutes. This means that once parts have been mixed, the paint will start to chemically cure after this time. Ensure you remove the paint from the tin in this window. The paint will then be workable on your floor for up to 20 minutes. 

Pot life = Time to harden in pot following addition of hardener

Working Time = Time to apply product before it becomes unworkable
