Ok, so I took the advice and bought a portable Terminator 1200 and Turbo Hybrid.
Bought the Groutmaster and brush combo. Bought some viper venom sealer and magic wand.
Where on this site can I go to get advice on the sealing part of this?
I stopped by a friends house today and she's got tight grout lines. Not sure how I would seal this. She's got travertine floors.
Travertine and most natural stone gets sealed. When doing ceramic (man0made) tiles, you only seal the grout lines. For natural stone, you will seal the entire floor.
Sealer should be a penetrating or impregnating sealer that is absorbed by the stone. It fills nooks and crannnies, pores and capillaries in the stone to help keep liquid spills out. It should not change the appearance of the stone.
A sealer can be applied to travertine with a flat mop or a finish applicator mop or even a moss rubber (foam) squeegee.
Some portions of the stone will be more absorbent than others. It is importnat to apply enough sealer to fill the voids but not too much sealer that will dry on the surface and become tacky or sticky. If part of the stone seems to dry quickly, you need to apply more sealer there. If some of the sealer is not soaking in but might start to dry on the surface, that needs to be wiped up or spread around to a dry area that needs it.
