The job took around three hours, I am going to re-sand using kiln-dried sand on the next dry day.Tools I used were a combination of flat surface cleaner and turbo nozzle, then I have a dual lance I used the low pressure side to swill down with. The weeds were a nightmare I have a little hand tool to remove these and I have advised my sister to buy some weedkiller which she has and she is going to apply it today.
