Will ArmorRenew ‘fix’ my deck wood or concrete?

ArmorRenew will fill in minor imperfections up to 1/4″. It is a coating that covers splintering and disintegrating areas. It is though not ‘magic’ and can’t repair rotted or severely damaged wood or large gaps and holes. Any unsafe or rotted boards should be replaced as necessary. Large holes in concrete should be repaired with a concrete patch. Raised boards should be screwed down with galvanized or stainless deck screws. If in doubt, contact a licensed contractor to review your deck or surface.
