How to use
Surface preparation
The substrate should be sound, dry, fully cured (not subject to shrinkage) and free from oil, grease, dust and other contaminants. Any laitance or surface treatment materials must be removed by mechanical means such as grit blasting.
Application
Apply KingFloor Primer C diluted with 3 parts of potable water with a low pressure spray to the prepared surfaces; Brush and roller can be used for small areas.
Apply 2 coats of KingFloor Primer C; The second coat should be applied at a right angle to the first coat.
The second coat may be applied as soon as the first
coat has initially dried. Drying time will depend on the substrate and the ambient conditions. If the over coating time is exceeded the first coat must be abraded with sand paper prior to the application of the second coat.
Cleaning
Tools and equipment can be cleaned with water when product is still wet. Hardened materials should be cleaned mechanically.
Limitations and notes
- KingFloor Primer C should not be applied at temperatures below 0°C.
- Do not apply if rain is expected within 8 hours.
- Do not apply to surfaces treated with curing compounds.
