Its time toc lean my terracotta Ive spent the last two months fixing (damn british weather!!)...

Of course Ive had to work fast and in quite intensive heat thus not had as much time to clean off excess adhesive. I have managed to get the majority of it off now with a range of LTP products and am now looking to hire either a floor scrubber or a scarifier.

Which do you think would do the best job?? Im not looking to grind the surface down really as Ive spent alot of time building an awful lot of drainage points and levels. Am looking for one massive cleaning session then a few drying days before the final seal...
