Can it be done in the school holidays?
Usually, yes, planned block by block. FloorGuard R50 needs seven days to final cure, so the programme puts the classrooms early in the holiday and the walkways and toilets around them, with every area cured before the term starts.
The primer and R50 are solvent-free and WB58 is water-based, so a block can be worked on while the school office next to it stays open.
