Stone Restoration
Continued from page 20
The terrazzo foyer and concrete stairs had to be honed to remove any old coatings and restore con- sistency. The stairs required strip- ping and honing to remove the years of finish and waxes that had been applied. The terrazzo foyer was honed with Triple Thick 220 grit and 400 grit diamonds, and finally polished with Majestic 5X Gold and a natural hair pad. Border edging was completed using 220 grit and 400 grit AA5 Turbo resins on a Makita slow speed right angle hand tool, prior to each grit on the floor machine. Stairs were honed with a 400 grit ELF electroplated metal-bond diamond.
At the request of the homeowner, a matte finish topical sealer was applied to all of the tile, grout, and concrete stair surfaces once every- thing had sufficiently dried. About three applications of the sealer were eventually applied. Nothing topical was applied to the terrazzo.
The tile, concrete and terrazzo surfaces all turned out looking very good. The contrast between the be- fore and after was very sharp. This
was another historic and unique home project that was completed with outstanding results.
As always, I recommend sub- mitting a test area to confirm both the results and the procedure prior to starting a stone or hard surface restoration or maintenance project. Also, the best way to help ensure success is by partnering with a good distributor. I have worked with
Braxton-Bragg for many years. They really know their products and can help with technical sup- port, product purchase decisions, logistics, and other pertinent proj- ect information.
