Choosing The Right Caulk For Your Project


A successful do-it-yourself project depends on the details. From kitchen sinks, to baseboard gaps, to bathroom surfaces – choosing the right caulk for the job is critical to prevent long term damage, or the need to repeat your efforts.

While there are many different types of caulk, the most commonly used are acrylic and silicone.

Different types of caulk are designed for different purposes, and can withstand different conditions. Caulking has a variety of uses, including insulation, painting prep, and moisture prevention.

Acrylic caulk is easy to use, and cleans up well.

It provides a neat, clean seal and works especially well for painting preparation, because it can be used to fill gaps between walls, ceilings, and trim. It is important to note that silicone caulk, due to it’s rubberized, water-repelling nature, cannot be painted. Acrylic caulk must be used if you plan to paint over it!

Acrylic caulk can also be used to keep your home comfortable in the winter by sealing gaps around windows, doors, baseboards, and switch plates to keep the warm air in and the cold air out! It can also be used to seal water out, but since it shrinks and warps over time, it is not the best choice for this application. For bathrooms and sink areas, we recommend using silicone caulk.

Silicone Caulk remains flexible for most of its lifetime without peeling, cracking or distorting.

Silicone caulking is an excellent choice for outdoor use and for protecting the home from outdoor wet-weather conditions because it is long lasting and resilient. Just remember – silicone caulk’s moisture-repelling properties will not allow it to be painted.

Often referred to as “rubberized silicone”, this versatile caulk will stay waterproof and hold a barrier against moisture significantly longer than acrylic caulking. That’s why silicone caulk is preferred over acrylic caulk around showers, bathtubs, sinks and toilets. Leaks are never a good thing, but are even more dangerous when you assume they don’t exist following your sealing efforts.
