I'm about to replace a shower door and I never want to see gobs of white
caulk again. I want to see next to nothing at all, like a minimum of clear
silicone and with hopefully none of that showing on the inside and nothing
at all on the outside. Am I barking up the wrong tree?
Need to know the door frame and entry materials. If it is aluminum against
tile, you could use a sparingly applied bead of clear silicone sealant,
cutting off just the tip of the nozzle for a fine line. There may also be a
way to goop up the area behind the frame as it is installed, and wipe away
excess, then screw the frame down to the tile.
I think norminn is right, and sounds like he's had a practical reason why
*not* to fill the frame with silicone. It's likely better to keep from
filling the back of the frame with goop. Just mount frame on fiberglass, and
apply narrow bead of clear silicone caulk along the shower-side joint. If
you don't like the look of the gap on the outside, you could apply a small
bead of acrylic caulk, which you can find in various colors.. Silicone seems
to resist mold/mildew better than the paintable caulks, so that would be
best inside the stall.
Everyone has his own way of making a neat line with caulk, ranging from
using finger, masking tape, smoothing tool, etc. I just squeeze it on in a
pushing action, with minimal nozzle opening, and it looks great, without
messing further with it. Also, I second the advice that you have to have
both surfaces super clean for silicone to "take" and be waterproof. I use
Fantastic, rinse, dry, then alcohol or some other solvent to etch the
plastic wall slightly.
On the *super clean* issue, any tips on cleaning the old white caulk? Just
scraping or does anything soften it up?
One thing I have learned from the past is to pay special attention to the
junctions at the bottoms of the vertical members. Probably can't get *too*
much caulk under the ends of the horizontal member to seal that. Again,
visible silicone on the exposed part of those two joints also eventually
No. Make sure it is CLEAN - wipe with straight bleach and dry before
beginning. Tape the edges before you caulk, removed tape as soon as you
have put in the caulk. Clear silicone is nice. Don't "goop up" between
the frame and the fiberglass - unless you want to stand in puddles of
goop when you get out of the shower. More is not better. Don't ask how
I know :o)
When we changed doors I had to do the caulking. I found some at Home Depot
in a tube like a toothpaste tube...it is lots easier to control than putting
it on with a caulking gun. There is a clear that looks white when it is
fresh and turns clear when dry. I had best results with it.
