How to prepare PY5 for anchoring dowels and bars

  • Holes should be either drilled using percussion drill or scabbled to provide roughened faces.
  • Pre-formed holes should be scabbled to provide a key.
  • Holes must be free from water, dust and any debris that might affect bond.
  • Dowels or bars should be either deformed or threaded; smooth bars are not recommended.

How to prepare PY5 as a flowable mortar

  • PY5 is the ideal accompaniment of PY4 when bedding ironwork.
  • Its flowable texture when mixed can be poured around the frame ensuring all voids are filled.
  • With its high early compressive, flexural and tensile strengths, this material creates a long lasting repair in the most arduous situations.

How to mix PY5 Polyester Resin Bedding Mortar

PY5 should be mixed by forced action mixer or by vigorous hand mixing with an appropriate tool:
  1. Add one tin of resin to the pack of filler/activator (or 2 tins of resin to the 2 filler/ activators).
  2. Pour resin from the tin into the outer bucket and slowly add the filler until a homogeneous mix is attained.
  3. Do not part-mix material. Use immediately after mixing.

How to apply PY5 Polyester Resin Bedding Mortar

  • Apply the PY5 material immediately after mixing.
  • Do not try to re-mix once initial hardening is evident.
  • Do not lay in standing water.
