Dust-free mortar makes a fine fixer
COMBINING epoxy resin with finely graded aggregate results in a non-dusting repair compound for filling holes, gaps or cracks.
Surrey-based Watco says its Concrex repair mortar is resistant to chemicals, including petrol, lactic acid, caustic soda and cutting oils, and cures to an impervious non-slip surface in 3-6 hours without shrinking or lifting. It comes in 10kg (22lb) or 50kg (110lb) packs.
For use in cold winter months or in cold stores, Concrex Cold Set can be used in temperatures as low as 10C, Watco says. Prices of the two are £38 and £50/10kg pack, respectively (01483-425000).
