Application Guide:

  1. Surface and Substrate Preparation: Ensure surfaces are clean, sound, and free of contaminants. Saturate with water for at least 4 hours, then remove excess water.
  2. Formwork: Construct leak-proof formwork, ensuring a grout head is maintained. Coat formwork with oil for easy removal.
  3. Mixing: Use a mechanical mixer. Add Penatech GP Grout powder to pre-measured water (2.2-4.0 litres per 20kg bag depending on desired consistency). Mix for 3-5 minutes.
  4. Placement: Use gravity flow with a header box or pump for large volumes. Ensure continuous flow and avoid air entrapment.
  5. Curing: Cover exposed grout with plastic sheeting, wet hessian, or curing compound.

Limitations:

  • Consult the manufacturer for grouting thicknesses over 200mm.
  • Adjust mixing and application for temperatures below 10°C or above 30°C.
