For our customers looking for a caulking, we try our best to help pick the best product for their application.
Our best most
versatile caulk is the DAP ALEX PLUS. This is an all around caulk that can
be used on a large variety of construction materials. This is a painter’s caulk
with added silicone for adhesion, flexibility and longevity. It has a 35 year
expected life in most applications and can be used indoors and outdoors. This
product is easy to apply and easy to clean up.
It provides a waterproof seal and keeps air from passing
through cracks. It is an excellent product for weather proofing a home. The
cured caulk is mildew resistant.
The caulk can be cleaned up with soap and water before it
dries. It has very little odor and is low VOC.
The ALEX PLUS will
stick to wood, metal, glass, tiles, drywall, brick, plaster, painted surfaces
and most building material. It is perfect for sealing windows and door frames,
molding, vents, baseboard, siding, corner joints and almost anywhere you need
to cover a crack or seam.
The cured caulk can be painted in about 2 hours. You should
apply it above 40 degrees.
For projects that
need the ultimate in adhesion or waterproofing silicone stands up to extremes.
For many projects in the bathroom, like shower doors,
silicone provides a much better seal and longer life. The DAP 100% silicone
that we carry has an expected life of 50 years.
Silicone is an excellent adhesive, so for outdoor projects
that need strength and a waterproof finish, silicone is the best. It will also
withstand extreme temperature swings, from -40 to 400 degrees. The cured
product is flexible and will not crack, crumble or shrink.
The product needs to have air movement to fully cure. You
can’t use it in a closed, confined space. Excess product has to be cleaned up
with mineral spirits. The product is very sticky and you only have 5 to 10
minutes to smooth or tool the product. It is much easier to use a caulking tool
to finish silicone rather than your finger.
Silicone is not recommended on cement, brass, iron,
galvanized metal, wet surfaces, oily woods, stove pipes or chimneys.
100% silicone can’t
be painted.
For some bathroom projects that need something stronger than
a bath caulk, silicone is the answer. It is also great for exterior projects
like gutter leaks and weatherproofing around doors, windows and siding.
In
most cases, the easiest product for the average homeowner will be caulk.
