Rot needs four major components in order to continue growing:
- Food
- Moisture
- Oxygen
- Warmth
By cutting off just one of these components is enough to cause the rot to go dormant.
If rot areas are left the wood rot pores will continue to cause more rot.
This is why we recommend removing the rotten wood and replacing it with fresh wood that is sealed with several coats 521 Marine Grade Epoxy.
