RE: [sccpartners] Travertine with bad grouting job John Freitag 18 Nov 2010 08:51 EST
Baird, If you go down to a 50 grit diamond plan on opening holes in the floor and you will probably need to fill all the holes. I would recommend staying away from that. I would approach the job by going in and cutting the grout down the approximately 1/8 of an inch then using a fine tool or other methods you may prefer to remove the grout. Then I would re-grout the floor using a non sanded grout but would use a latex additive to the grout. I would use at least 50 to 70 % latex and the remainder water when mixing the grout. The latex will improve the bonding of the new grout to the old grout. When using the latex additive the grout will cure much faster so your pot life will be short. Mix up small batches of grout. Even though most grout have latex already added you will need to add more. The latex additive can be purchased in Home Depot and other tile supplier. It's usually in the tile section by the setting materials and grouts. John E.

The tiles are not finished well, with much irregularity to the polish. The key point is that the grouting (traverfill or maybe just plain unsanded grout, probably the latter), is not well done. Some of the grout is flush with the surface but much of it is below the level of the travertine surface. The surface itself is smooth and scratch free, so I could otherwise finish it with one 400 grit hone and polish, but it looks like I will need to use a 50 grit diamond to grind down the floor to even out the grout, then work up from there. I'm wondering if it is possible to grout over the existing grout effectively (without it coming loose) and cut back on the number of hones?
