I've just completed polishing a test area for a customer who has 500 sq ft of marble flooring that has been waxed for almost 30 years with acrylic floor wax. Needless to say, after removing the wax buildup and honing and polishing a test area, the difference was like day and night and they would like the entire floor done. The test area was at a rectangular front door entrance bordered by a wood floor on two sides with a wooden T-molding border. About an inch or so from the T-molding and at the 90 degree angles I wasn't able to hone or polish very well. You could see picture framing in the corners and about a one inch line along the T-molding where I couldn't overlap with the diamond pads or polishing powder. All suggestions on how to handle these area most efficiently would be appreciated. There are many more 90 degree angles and areas under kitchen cabinets that may pose the same problem. I do have a makita and 5" diamonds and understand that all this may be handwork, but some of the angles may be too small even for the 5" diamonds. Is there a smaller backer pad that we could use with 3" diamonds? I'm not aware to this yet, and if so, I must get one. This is my first "major" job and any help would be appreciated.
