Retrofit access panel in older plaster walls?
Victorian house with horsehair plaster—anybody added a clean access point without cracking the whole wall? Need to reach the radiator valve.

Plaster hates vibration, so no hammering. This access panel comes with a scoring guide that lets you cut precisely with a utility knife. I removed a small section, buttered the edges with plaster mix, and pressed it in. The plastic flexes just enough to follow the wall's curve without stress fractures. Looks original once painted; valve access without ruining the period charm.
