A fine-toothed saw can be used to cut plastic trim. The finer the teeth, the smoother the cut.
Plastic trims, whether rigid or flexible, can be cut using tools such as a miter saw, handsaw or hacksaw. The most important factor is that the saw has fine teeth, which helps minimise chipping and ensures a cleaner result, especially for rigid PVC trims.
Before cutting, always secure the trim properly and cut with steady, controlled motion. For thinner or more flexible profiles, hand tools may be sufficient. The best tool depends on the type of trim, its thickness and the level of accuracy required.
