Re: travertine | | WetDec will be along shortly I reckon....
For my two-penneth, if the floor isn't huge I would work my way through a range of sand papers - start with fine grade and work through to extra fine / wet&dry to give a uniform finish. Clean away all dust and slurry and seal properly with a good quality penetrating sealer.
If the floor is large, then it may be best to call in a professional! |
