Q: What surfaces does the self-adhesive window felt strip stick to?

A: The strip is designed to adhere to most clean, smooth, and dry surfaces including PVC window frames, painted wood, glass edges, tile, and plaster walls. For best results, ensure the surface is free of dust, grease, or moisture before applying.

Q: Can the water-absorbing felt strip be reused or repositioned?

A: This strip is designed for a long-term, permanent bond. Once applied, it is not intended to be repositioned. If you need to replace it, simply peel it away and apply a fresh strip to the clean surface.
