Resbuild Polyester Mortar is a versatile, rapid curing, high strength, two pack mortar suitable for many applications in building and civil engineering. The product consists of a low viscosity unsaturated polyester resin BASE component, and a FILLER component consisting of graded minerals and catalyst. Resbuild Polyester Mortar has a non-critical mix ratio, which allows the consistency to be varied from pourable to trowellable without adversely affecting curing times or strength.

For rapid repairs, bedding, jointing and profiling of concrete, masonry and brickwork. Repair of in-situ and pre-cast concrete. As an adhesive for bedding and fixing kerbs, brick slips, manhole sets, concrete slabs, etc.

Resbuild Polyester Mortar will have hardened sufficiently after 1 hour at 20°C or 2 hours at 10°C, to allow full trafficking or overcoating. Full mechanical and chemical resistant properties will be
achieved after 7 days @ 20°C.

Remove all laitance, spalled concrete, grease, oil, dust, and other contaminants by mechanical means e.g. scabbling or needle gunning, to provide a sound, clean
substrate. Any exposed reinforcing steel shall be fully exposed by cutting out around its full circumference, and cleaned by hand abrading or wire brushing to remove rust, scale, etc.

A 6kg pack yields 3.30 litres of mortar, sufficient for 0.66m² @ 5mm thickness.
