In this video, you will learn about silicone and spray foam. There are many different types of spray foams and caulking. Repairing a bathtub is a common reason people need caulking. This can be a simple project that only requires minimal tools.
You want to make sure if you are using a knife that your tub is porcelain and not fiberglass. There are other tools like a pick that will get behind the caulking. Once you get the old caulking out, you might want to use some alcohol to clean the surface. Take a small tube of caulking. There is a lot to choose from. Some of them are silicone-based and there are fiberglass. YOu might consider using a caulking gun, or if the area is small enough, you could squeeze right from the tube. If you are applying from the tube, you’ll want to make sure you smoothly fill the crack with an even squeeze and steady push. Try not to start and stop. If you want, you could use your finger or a rag to spread it evenly. If you are interested in learning more, keep watching this video for more information.
