2 professional tile guys working together that know what they are doing would probably take 2 full day or 40-50 man hours to do a strip and wax job like that saltilo.....
It would probably take you 150+ hours to do it right the first time......
unless you had someone on the job site working with you showing you what to do.....then maybe you could do it in 2-3 days????
you got 3 choices imo:
- pass on the job
- do the (anderson) clean the grout only thing
which can still be tricky around the waxed tile!!!!
no buffer...using grout stick .....scrub only the grout lines....
then seal the grout lines!!!!!
3. hire a tile guy to work with you who knows what he is doing
and you take a small cut of the job...as learning experience...
however good experience as i have run into ceramic tile that has been waxed and didnt know it...always ask....
also you will run into more frequently color sealed grout lines...
that is a whole other problem in itself?????
