The anti-mildew tape is flexible and it comes with a middle crease that can be folded into 90° for an optimum sealing in the seams between walls. Allowing you to smoothly adhere it through corners and curves without bubbles entering through. Ideal for bathtubs, toilets, sinks, stoves, windows, walls, and other surfaces that easily get mildews and molds. Simply clean the surface you need to stick on, remove the back film, adhere the caulk tape firmly and cut off the excess, then wait for it to dry off and you're done. No more caulking glues or time-consuming installation needed!
