Hi,
I'm about to replace the sealant around the bathtub but have a quick question.
First, assume that I've removed the old sealant (only around the bathtub edge where it meets the wall tiles), then cleaned the gap thoroughly with methylated spirit, and now ready to apply the new sealant (Dow 785+).
My question is what happens at the corners where you also have a silicon bead running up the wall between the corner wall tiles (see attached photo with red arrow).
Am I meant to also apply a new silicon bead on top of the old one running up the corner?.. if not then isn't there a risk that water will seep where the new sealant applied around the bathtub meets the existing silicon bead running down the corner wall? (hope that makes sense)
OR... am I meant to remove not only the old sealant around the bathtub edge but also the silicon bead running up the corners. Then apply sealant around both the bathtub AND up the corners right up to the ceiling?... which sounds like a lot more work!
In my bathroom the silicon bead running up the corners is in very good condition, it's just the sealant around the bathtub that has patches of black mould on it plus has come loose in spots.
Your advice here would be much appreciated :-)
Thanks
