Ipe Seal® end grain sealant is a wax emulsion proven to increase the structural integrity of hardwoods and thermal wood end cuts. Designed to prevent checking (drying splits) in deck boards, freshly sawn logs, lumber, turning blanks, and other exposed wood ends. Ipe Seal® creates a bond that extends the life of wood. Apply to end cuts on exotic hardwoods, thermal wood, and composite material as well as hardwood siding end cuts. Ipe Seal® seals the ends of logs and lumber to protect against costly degrade during air-drying before processing or kiln-drying.
