InstaTrim's wedge shape covers gaps between surfaces and has patented flexible wings on either side for extra coverage and protection against dust, dirt, moisture, air movement and bugs. InstaTrim flexible molding has many uses. It can be used as a finish trim to cover sloppy painting on wall corners, as a caulk strip to keep moisture from seeping through gaps around a sink, along a backsplash, bathtub or shower, as tile edge trim in bathrooms and kitchens or as a flexible quarter-round moulding on baseboards and floors. Apply InstaTrim to window and door trim instead of weather strips to keep your energy bills low, use it as wood edging to cover uneven gaps around baseboards, floors and wall cabinets or apply this peel and stick caulk on the base of a toilet to keep your bathroom sanitary and easy to keep clean. InstaTrim gives you a perfect line every time in just minutes. InstaTrim is so much easier to work with than caulking, it leaves no mess and does not need time to cure, it's also paintable. It adheres to nearly any surface - tile, ceramic, wood, vinyl, laminate, metal, concrete, granite, stone, wallpaper, paint, wallboard and more. If you plan to use this self-adhesive, flexible trim to replace old grout or caulk, make sure you remove all traces of silicone from the surfaces before installing InstaTrim. Instructions for proper silicone removal and surface prep are included in the package. Also look for our 3/4-inch wide InstaTrim if your gap is just a bit wider. Color: White. Material: PVC.
