Caulk is often used in household repairs, particularly when it comes to the upkeep of bathroom and kitchen areas. To avoid the issue of having to match new caulk to the old material or the existing color scheme of the room, clear caulk can be used in many cases. Additionally, if you want the color of the surface to show through a layer of this substance, clear caulk might be best. Choosing the best type involves finding one that will last as long as you need it to, is easy to apply, and does the job you need it to do.

Silicone caulk is frequently clear, which makes it popular among those who do not want to deal with matching colored caulk to a surface. It is typically the best kind of clear caulk to use in tub and shower repair, since it can boast a waterproof seal for years. Once applied, it usually stays flexible without cracking or drying. This also makes it appropriate to apply outside to keep water out. On the other hand, silicone caulk is often difficult to apply, and cannot be painted over.

If your goal is not to stop water leaks, but instead prevent air leaks, acrylic caulk might be the best choice for you. This is one type of clear caulk that is known for being easy to apply, and is ideal for stopping air from leaking in or out of surfaces. Many people apply this substance before painting in order to fill in any gaps, or around windows and doors to stop air leaks. It does not typically last as long as silicon caulk does, but its ease of use means nearly anyone can use it effectively.

Another choice for clear caulk is urethane, which is known for lasting about as long as silicone caulk does. Unfortunately, it is about as difficult to apply, and takes days to completely dry. Once it does, it is known for sticking to surfaces quite well, which is why it can be used for heavy-duty projects. It is often used to fill cracks in surfaces like vinyl siding and wood. As long as you wait long enough to let it dry, it is paintable, but only when it comes to water-based or oil-based paint. Since only certain types of paint can be used on this substance, and only after proper drying time, many people choose to keep it simple and use clear urethane caulk.
