If you do a lot of home repair you may find that you will need to use caulking at one time or another. Caulking is made from many different materials and for a variety of purposes, but all have one common use, and that is to fill cracks, gaps, and seams. Caulking is a rubbery, flexible substance similar to thick toothpaste that is used around windows, bathtubs, sinks, siding and more to help seal cracks and gaps. Depending on the type of caulk, it can last between two and thirty years.
Caulk is sometimes sold in small squeezable containers for easy application, but will be found most often in disposable tubes used in a caulking gun. The gun works with a trigger to push the caulking through a small tip that is then applied in what is referred to as a bead, or strip. The following information can help you make an informed decision the next time you need to purchase caulking.
Latex caulk, while easy to clean with water, does not have a very long life, so is a good caulk for weather stripping or anything that you would want to redo regularly. Most latex caulks are paintable, but are also sold in a variety of colors that can be matched to paint or tile. Latex caulk is best used on small projects and is available not only in the large tubes, but also small single-use varieties.
Acrylic caulk is similar to latex in that it is very easy to clean. It has no odor and lasts a bit longer than latex caulk. Acrylic caulk will usually take paint and is often used on exterior siding and to seal around window trim and doors. Acrylic Latex Silicone has many of the same features as the previous two, but has the advantage of lasting longer and being very easy to apply.
Silicone caulk is by far the most versatile of all the caulking available. It can be used anywhere and is often favored for areas where there will be a lot of water, such as bathrooms, kitchens, and exterior siding. Silicone caulk also works extremely well around tile and faucets. Silicone caulk does not take paint, but can be purchased in white, brown, tan, and even clear. Silicone caulk lasts the longest of any of the others and can be removed without too much trouble.
Other types of caulking include rope caulk, butyl, and foam. Rope caulk is sold pre-formed into strips or ropes that are flexible enough to work with your hands. Rope caulk is ideal for weather stripping because it can be removed when winter has passed without much fuss or mess. Butyl caulk is similar to acrylic caulk in clean-up and uses but may shrink a little with time. It is not recommended for areas with very cold weather. There is also something known as expansion foam. Although this foam is not technically a caulk, it can be used in similar situations. Foam is sold in aerosol cans and expands after it is sprayed into an area, leaving seams well filled with good coverage. It is very difficult to clean and make take a while to dry completely.
Before you begin your project you must remember to follow a few simple rules. One thing to remember is to never apply caulking in cold weather. Most caulk will not adhere well to a surface in temperatures below forty degrees. It is also advisable to not caulk a crack or seam when it is too humid. In lower humidity, the surface (especially wood) will have less swelling and be easier to mend. As with all products used for your home it is a good idea to check the individual manufacturer’s directions and hazards before starting any project.
Caulking is a great for sealing areas on the exterior or interior of your home, and can keep unwanted water from entering your home at various cracks and seams. The next time you need to use caulking choose the appropriate type for your project and you can get the job done right the very first time.
