Getting everything ready
When all of the debris have been removed and the
cleaners are dry, it is time to put down the caulk. If you are using 100%
silicone (and you should be), it is a very good idea to first tape the joints.
Using masking tape, put a piece of tape on either side of the joint. The
exposed joint should be anywhere from 1/8" - 1/4" wide. You should tape all of
the joints before applying caulk.
Get a small cup or coffee mug and fill it 1/2 full of
water. To the water add a bit of liquid soap. Put your fingers in the water
and rub them together. Your fingers should "slide" over one another. If they
do not, add some more soap.
Using a razor knife, trim the plastic tip on the
caulk tube. Cut near the end of the tip, it is better to put on too little
caulk and add more later than to put on too much and have to pull it off. The
cut should leave the tip with a 30-45 degree angle cut.
