Bathroom Caulking

Here ya go, Dottie. The secrets are caulk softener and Tub & Tile caulk. DAP is the brand I've always found at Home Despots and the like.

Another tip is to fill the tub with water before you caulk so it does any settling and opens up the gap. Otherwise, it might pull apart (if the flooring isn't 100%) and let water seep down.

What does the discoloration look like? Is it more mold? One thing I recently learned is that mold many times grows from the inside out out. For example, from behind the tile which is wet due to failed grout joints.

I am in the midst of a bath room project that had greenboard. There was always mold growing. The green board was totally soaked behind the tile.

I wouldn't panic yet. Mold grows easily behind caulk and will disrupt the seal if it wasn't clean when the caulk put in. Contractor told me to clean with straight bleach and let dry before caulking - worked for me.

Thanks. I will be careful to clean it good before I re-do it and use Clorox to kill the existing mold.

This is only the area around the shower door, where it meets the tub. I used DAP before....the problem may very well be the way I prepped and applied it rather than what I used.

If it is on tile, and you can use a razor blade scraper, I would do so. Then take denatured alcohol to be sure you get all the soap scum, as it almost assures failure if left on surface. I don't think brand matters - DAP and GE? are the only memorable brands. I would use only silicone for shower (non-paintable).
