How to Use FP McCann Priming Slurry
Application Guidance
- When using this product, good site practice should always apply. FP McCann cannot be held responsible where workmanship has failed to meet the relevant European and British Standards.
- Freshly laid paving should be protected from frost and inclement weather.
- Cement based products will take longer to harden and set at lower temperatures, and should not be used below 5°C. When site temperatures are below 10°C allow extra time for hardening. The base or paving should not be frozen before or during application.
- Prior to use, all surfaces (base and paving units) must be sound, clean and free from any loose material or any other contamination including oils, grease and curing membranes.
- All absorbent substrates should be pre-soaked with water but free from puddles or standing water.
- The primer should be applied by trowel or stiff brush to a thickness of 1mm-2mm.
- When priming prior to the application of Paving Mortar, it should be applied onto the supporting layer/roadbase immediately prior to the application of the laying course.
- When applying to the underside of paving units do so immediately prior to their placement upon Paving Mortar.
- Allow a minimum of 12 hours before light foot traffic and 1-2 days before vehicular traffic, depending on site conditions.
Mixing & Water Guidance
- FP McCann Priming Slurry should be mixed using the correct amount of water by using a mechanical mixing method such as using a suitable slow speed high torque drill and mixing paddle or larger amounts mixed in a suitable mixer pump system.
- Mix to a consistency suitable for the intended application. Typically, a 20kg bag should be mixed with 5 – 5.5 L of water.
- Mix product for a minimum of 3 minutes until a homogeneous consistency is achieved.
- Ensure mixed mortar is used within 60 minutes of mixing.
- Adding additional water or trying to revive a mix that has begun to go off will greatly reduce performance.
