use rubbing alcohol to clean up any remaining caulk and soap
residue. Go ahead and skip this step if you don't want your
new caulk to adhere very long. To keep caulk from creeping up
the grout joints when you smooth the bead, apply strips of tape
along the sides of the joint before applying the new caulk.
are a couple of tricks to laying down a smooth bead. First,
make an angled cut across the tip of the tube using a nice sharp
blade. You want it big enough for the caulk to flow smoothly,
you want the angle to match the angle at which you hold the
gun to the joint, and you don't want any plastic jaggies left
on the tip to drag through your caulk bead. Next, apply the
caulk moving the gun steadily and surely. Do yourself a favor
and get a good caulk gun that has a smooth trigger action and
stops dispensing when you release the trigger.
smooth the joint with a moistened fingertip or a caulk-smoothing
tool. If you used tape, pull it up gently to avoid dinging the
the damage is limited, you just need to dig out the affected
joints. If there are gaping, nasty cracks, you're better off
digging out all the joints. The tool you need here is a grout
saw; they come with either a serrated carbide blade or an abrasive
blade. Working slowly and methodically, use the saw the dig
out the old grout. Wear safety glasses! To avoid scratching
or chipping the tile, pay close attention and don't go too fast.
Be sure to vacuum all the debris from the joints.
small areas you can pick up premixed grout that comes in a small
tub or tube. For larger areas you're better off mixing up a
batch of powdered grout. For greater strength and water resistance,
use a polymer-modified grout or mix up plain grout using a latex
apply the grout, scoop some out of the bucket and slap it on
the wall. Using a rubber grout float, work the grout into the
joints. Work the float diagonally across the tiles and angle
it about 30 degrees. To remove the excess, hold the float almost
perpendicular to the tiles, again working diagonally across
the tile has set up about ten minutes, it's time to clean off
the remaining grout. First wipe off as much grout as you canóuse
a clean grout sponge and make slow circular motions. Next shape
the joints by running the rounded edge of the damp grout sponge
along the joints. Finally, make a last cleaning pass with a
clean sponge. Use gentle pressure and make only one pass with
each side of the sponge before rinsing it.
the tile dries, a thin haze will form. Polish this off with
a clean soft rag.
