preventing mold

Killing mold on wood requires eliminating it at the root — surface scrubbing alone doesn’t work because mold hyphae penetrate wood grain and regrow within weeks. The correct approach depends on wood porosity: sealed or painted wood may respond to scrubbing and antimicrobial treatment, while structural framing or unfinished wood often requires sanding or replacement.
