The main decorative install layers were made up of four different polyurethane coats applied in different thicknesses and applications. To allow for sufficient curing it was only possible to install one layer a day.
The biggest issue with these systems is always contamination between layers, dust or detritus showing through the next day, so all operatives will be wearing Tyvek suits, over shoes, gloves etc to minimise contamination.
This process took a further 5 days allowing for 2 coats of PU 3320 pigmented seal coat.
