"First time of using one of these, and I must say it made the job easier. I grouted a 15m squared floor in an hour. As long as you keep it at 45 degrees like plastering and the grout not to thick job done."
"I wish I had one of these years ago but then maybe I wouldn't have appreciated how fantastic this tool is. I can't emphasise how much I hate grouting, but this tool made it so much easier and possibly even a pleasure.
I was only doing a new shower area - about 6 square metres - but this float was worth every penny. It fully forced the grout into the joints and left a consistent finish.
One end as rounded corners, one end square, but I only needed the square ones. Large solid handle which was easy to grip.
