Grouting tiles seems to me the most perverse building-related type of work: first you do your best to goop up your Nice New Tiles, (wait 30m), then you do your best to wipe and wash off most of the bloody gunk again.
Combined with my "love" for cleaning this is not a happy exercise.
Still and all it was to be done, and so I spent this arvo first prepping and then grouting all the bathroom walls. No photos right now, because during the work I was way too busy for snapping pix, and afterwards I had the joy of cleaning up the mess, and now I'm too tired.
