Builda Rep S62

Trowel grade overhead concrete repair mortar

Two-component polymer cementitious repair mortar for rapid overhead, vertical and masonry repairs.

  • Fast setting for rapid repairs
  • Suitable for vertical and overhead patching
  • Excellent bond to sound concrete
  • High compressive strength

Surface Preparation

Concrete must be clean and rough. Remove oil, dirt, debris, paint and unsound concrete. Mechanically prepare to minimum 3 mm surface profile

Reinforcement Treatment

Exposed rebar should be cleaned of rust and treated with anti-corrosion coating such as Zinc Rich Primer

Mixing

Small quantities may be mixed with a drill and jiffy mixer; use paddle type mortar mixer for larger jobs. Do not mix more than can be placed within working time

Application

Apply to prepared repair areas by trowel, consolidating firmly into the substrate
