Some home improvement products are truly magical, and caulk is one of them. Used to seal edges and corners in cracks, tile, and masonry, caulk can cure your drafty window problem or easily touch up your bathroom tile. It can even be used to repair old wallpaper that's starting to peel away from the wall or fill cracks in your driveway.

The rubbery substance comes in a range of formulas—including silicone, latex, and polyurethane foam—making it handy for various indoor and outdoor home projects. That is, of course, if you apply it correctly! If you need help getting started, we have you covered with a step-by-step tutorial on how to use caulk. Apply this process to any edges, corners, or holes in your home, and they'll be properly fixed up in no time.
