Silicone Sealer stained grout

[Westcoast]

Hello,

What is the best silicone sealer to use over grout around the tub? I used GE sealant Silicone II, clear sealer for kitchen and bath, and now the grout has a "wet" look which is not what I want. The grout now looks darker where I have used the silicone compared to the rest of the shower. I made sure that the area was clean and dry before applying.

Any suggestions on a different product?

Hi Monique :)

What brand/color grout do you have? As the silicone cures, it may lighten up. GE clear silicone also tends to fog after it cures, and starts going through wet / dry cycles.

The grout is Mapei "bone" kericolour. I did the sealant over a month ago and it still has a wet look which is darker than the bone colour.

Do you find that this is necessary after using the Mapei coloured caulking?

Hi Monique :)

I'm confused. You mention using two different products - GE Clear Silicone & Mapei Bone Caulk. Where did you use what, and where is the problem with what problem? Did you put the Clear over the Mapei Caulk? :scratch:

Did you seal the grout prior to caulking? It's not uncommon for a clear silicone to darken unsealed grout.

On the tube of acrylic caulk by Mapei it says "not for use in areas prone to constant water exposure" so I put the sealant directly on top. Should I have put a grout sealer on first before the silicone? Thanks John for your advice.

Hi Monique :)

Yes, I would have sealed the grout, then applied the silicone caulk.

Thanks John! Now I know what to do for next time...
