Regrouting bath tiles
The tiles on the wall for the bathtub are getting old looking and
some of the grout has black stains, likely from mold. Scrubbing lasts a week or so before the aged condition reasserts itself. Its a long time (25 years) since I last put them on and cannot remember the tricks to the trade. I'd like to do as little work as possible since there are so much more other "renovation" stuff I have to do too. First do I need to remove the grout and regrout? Or can I just apply fresh grout over the old? Only a few spots here and there have lost a little surface grout of flake thickness. This flake thick loss is not visible after I clean them. Can I scrub clean the whole wall and apply some form of polish then a sealer to restore the tiles? If so what brands should I get? My water supply is very hard and I think the dullness is from the film of soap-mineral deposits. |

Possibly you could avoid doing it all and instead only where you deem it necessary. |

However, in my case the grout was only a few years old, which would have made regrouting more difficult. I'd sealed the grout, but a small water leak caused surface rust stains from water coming up from under the grout. It turns out there are a number of products for "refreshing" grout that put the color back in. The cleaning products didn't work for me at all, although I used them to hopefully provide a better surface to work with. I just did it this weekend, & it looks wonderful. I have no idea how long it will last. However, the grout was white, & I bought a white pigmenting product. If I did it over, I think I would use a coloring agent to darken the grout, not make it light again. |

When my grout starts getting dark from mildew, etc, I clean it as best I can
with bleach and tsp, using a firm brush. Then I make a watery grout mix and spread it on like normal with a grout float. I let it dry, then wipe with a damp sponge, then a dry towel to polish. Not only does the grout look like new from the thin new layer, but the tiles shine like new as well. k "Alan Greenspam" wrote in message news:jybme.6448$Fb.3176@trndny07...
