Caulking timing

Hi All,

I'm hearing conflicting info on when to apply a silicone caulk bead during a tile project.

Is there any time when you should seal a location, then tile up to it?

It seems reasonable to tile up to a transition, then push caulking into the joint to get a full seal.

I'm referring to the joint between wall tile and sink top, tub apron and floor tile, bath surround and tub shoulder, etc.

Also, I currently have a tub in place on shims on slab. i'm afraid of it slipping during the remaining work (and with drain installed), so should I put a thin bead of silicone at the apron/slab joint to secure it (didn't get a chance to set the tub in plaster), then floor tile up to 1/8" shy and then push a final caulking bead in?

Or I could glue/caulk the backside of the apron via an access panel, any thoughts?


Thanks for all your advice.

Personally I'd use latex caulk not silicone. It is easier to work with and cleanup. With latex just a damp sponge to remove excess and smooth before it dries. With silicon no easy way. Caulk is applied after tiling.

Thanks, that sounds easier to use latex caulking.

Something I read recently said it doesn't get as good a bite in the joint as silicone, though.

Sounds like either is fine, I'll go with whatever is easiest for each application.
