caulk is the least expensive type of caulk. It is generally used for filling gaps in exterior
siding, and especially in places that will need to be painted (it holds water based paints well). It
can also be used to seal up frames, and around exterior windows and doors. It also can be used in
the interior of the house to cover mistakes in molding or trim that is to be painted. Acrylic caulks
do not always stand up well to extremes in weather. They should not be used around stovepipes or
other areas that get extremely hot. Many acrylic caulks have a silicone component which makes
them more flexible and more able to stand up to the weather.

caulk is the type generally used in baths and kitchens. It stands up very well to water and
adheres well to smooth and glazed surfaces such as tiles and metals. It comes in a wide variety of
colors to accommodate interior decorating. However, paint does not adhere well to it. It is flexible
even when dry and stands up well to temperature extremes, which makes it very versatile. It is not
always easy to apply; because it adheres so well, the slightest error can be problematic especially
in areas where there are aesthetic considerations. During application its odor can be disagreeable
for several hours. Silicone caulk can be used outdoors as well as indoors. It is often a component
in the more expensive, higher quality exterior caulks.

Bath is usually silicone. It may also have an anti-mildew chemical
added that will help fight mold in the damp corners of the house. It can come in squeezable tubes
that look like oversized toothpaste tubes. But these are often difficult to squeeze. When doing
large jobs, definitely opt for the standard tubes for use with a caulking gun . Here again, the odor
during application may be off-putting.

caulk is used in situations where connections between units must be water or air-tight.
A good example is metal roofing. The overlap is given a bead of adhesive caulk when it is
screwed to the plywood or OMB beneath, giving the roof a unified and impermeable structure.
Many adhesive caulks are water based, making for easier cleanup.

caulk is best used outside the house. It adheres well to most surfaces including
wood, aluminum, mortar, and plastics. This makes it excellent for use around gutters, down-spouts,
and other areas. Another advantage of butyl rubber is that it stands up well in extreme
temperatures. Krylon claims that their caulk remains flexible from -40 ° F to 180 ° F
