It was a long day, but it was worth it.
First was spraying on the cleaner/activator, then pressure washing, next was rinsing it thoroughly. After it was completely dry the first coat was applied. The overhang at the sides took the longest as it required brushing the coating on, the top was done with a roller. Once the first coat was dry, the second coat was applied.
The difference between the roof and the top of the slide is very apparent. Bad weather is in the forecast, so it will be a week or so before the slides are done. They are in much better shape than the roof was, but doing them all now makes sense.
