I agree...don't re-tool!
Also, my firebricks chip pretty easily on the edges - is this normal
?...firebricks are pretty soft so chipping will occur even if you are pretty careful...you can smooth off the egdes once the floor is laid using a angle grinder...
Even on my garage floor they are very uneven I'm going to have to level/grid the edges a bit...
Thanks
