Yes, Bor-Ram can be applied to any type of wood including the subfloor as long as the wood has not been painted, stained, or sealed and it is raw wood. There will be no issues with covering the subfloor with laminate after the Bor-Ram has had time to dry which is usually only 24 hours. Bor-Ram has been discontinued by the manufacturer, so we recommend that you use Bora-Care. Bora-Care is also a borate product that is used for wood treatments against wood destroying insects.
