I run across this problem all the time even when the issue is just Grout with ceramic or porcelain tile. The customer always wants everything to dry evenly and it's just an impossibility.50-50 bleach and water spray will reduce the mildew and that's probably all that can be done.No sealer is going to help because all they do is slow down penetration time once the shower is wet for a few minutes it passes through the sealer.If you add a topical coat sealer you'll just make it worse.I usually tell the customer in this situation it's going to be what it is because it's a bad choice of tiles and nothing can be done unless you tear it out and put in a different floor.I've tried so many times to try to fix these type of issue with no resolve.Not everything can be fixed.I see quite a few of these basket weave white marble surfaces.Besides the black,orange and pink mold and mildew, I see what I think is damp stained white marble.I cant get a real good pic of the caulking but it appears somewhat degraded.To me this is representative of a shower base that has moisture under the stone.This may be the result of the install. Check the moisture and tread lightly.Putting topical coatings on shower stall floors can be risky.Water is one powerful element to mess with-wins every time.The moisture in the pan will evaporate upwards. You can do the math.On Mon, Apr 24, 2017 at 6:39 PM, Mike Alston <realmikealston@gmail.com> wrote:I will be going to back to her home in a few days and take a moisture reading. Will share the results when I do. Than you all for all your help.
Sent from my iPhoneLooking at the pictures the color around the perimeter seems to be a pinkish/orange color. This can be caused by a build up of soap. If this is the case try a good soap film remover to remove the wax soap build up them try a proper mildew remover or bleach. to best clean the mildew.Bill SelikGourmet Stone CareOn Monday, April 24, 2017 10:44 AM, Blain Haeg <blain@goldstandardfloorcare.com > wrote:
Without knowing the results of the moisture reading, your solution to scrub the heck out of it, followed by a color seal may be adequate.Likely, regardless of a previous sealer application or any sealing that you provide post-cleaning, this floor will continue to have problems that can only be rectified by frequent scrubbing and cleaning.Mosaics on high-use shower floors are always a bad decision. Less grout = less maintenance, in my opinion.On Apr 24, 2017 12:20 PM, "Mike Alston" <realmikealston@gmail.com> wrote:Good afternoon Pros, a customer has a newly installed shower that is porcelain walls and marble mosaic floor. She had the shower installed last August and has been experiencing stains and molding for several weeks. I told the customer not to use the shower for a few days so I can take a moisture reading before we just jump to conclusions.
Before I left she told me the installer was a friend of a friend and did it seal it. She sealed it herself with products from the local hardware store. However, she was sure how long after the installation she did. Laticrete sent her their color seal but she is reluctant to use it. Would a good cleaning and color seal take care of her problem?
