Application Guide:
- 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.
- Formwork: Construct leak-proof formwork, ensuring a grout head is maintained. Coat formwork with oil for easy removal.
- 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.
- Placement: Use gravity flow with a header box or pump for large volumes. Ensure continuous flow and avoid air entrapment.
- 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.
