- What is open-cell foam good for?
- Open-cell foam lets air and moisture through, so it is used for cushioning, padding, acoustic damping and breathable gaskets. It is not the right choice where water or vapor must be blocked.
- How firm is this foam?
- It is rated medium hardness with a 20-40 Shore OO durometer, which is soft enough to compress by hand but holds shape better than light packing foam. It is not a firm seating or structural foam.
- Will the adhesive stick to wood and metal?
- The acrylic adhesive backing is designed to bond to clean, dry, smooth surfaces such as wood, metal and plastic. Dusty or oily surfaces should be wiped first for a lasting hold.
- Can I cut it to a smaller size?
- Yes. Polyurethane foam trims easily with a sharp blade or serrated knife, and the square can be cut down to fit smaller areas. Cut before peeling the backing for cleaner edges.
- Does it absorb water?
- Yes. Open-cell foam soaks up water and takes time to dry, so it is a poor fit for outdoor or wet areas. Closed-cell foam is the better choice there.
