Polyfilla Putty Gap Filler is a reliable and easy-to-use product for filling gaps and cracks around the home. It applies smoothly, dries quickly, and sands down well for a clean finish. Ideal for both interior and exterior use, it holds paint well and doesn’t shrink or crack over time. Great for DIY touch-ups and repairs.
