Several months ago, I took on a couple of bathroom remodel jobs and in all, I got called back due to mildew on the caulk. One job, I used GE Max 5000 Kitchen and Bath, another DAP and another job still Phenoseal and they all mildewed.

I cleaned all surfaces prior to caulking with bleach and know that the cure time was achieved since the homeowners weren't even around (on vacation).

Two questions?

1. What caulk should I switch to?
2. What can I do to make this job better?

Mildew can be prevented when the homeowner CLEANS THEIR HOME:laughing:.
Is it in the shower/tub area or sink/toilet area. Some clients need to know how to maintain what they purchase!

It depends on where the caulk is going, In a shower I would stay away from caulking as much as possible. If you had too, you might check at a tile supply like the Tile Shop. For around a sink or a counter I would think a standard silcone caulk would work......

Exterior: I pefer Solar Seal, your not suppose to use it inside through

Caulk where ever dissimilar materials join. :thumbsup:
Standard silicone sucks for mildew resistance. :no:

Ah... Caulking in a shower is a little different than around a sink.

Thanks for the info on where to caulk, I usually don't have to use it :thumbsup:

Try using Dow Corning 786 Mildew Resistant Sealant. Most of the stuff everyone else has listed is hardware store grade, which for the most part is garbage. This product should last you 10-20 years with out any problems.

The ingredient's that makes it resistant is formaldehydes..

The cheaper version of this product is called Dow Corning Tub Tile and Ceramic...:thumbsup:
