WiseSeal® End Grain Sealant - 16 oz with Brush Lid
WiseSeal® is a water-based, stainable end grain sealant that protects freshly cut wood ends from checking and splitting. The convenient 16-ounce bottle includes a built-in brush lid for easy, drip-free application directly in the field. Unlike petroleum-based sealers, WiseSeal® allows subsequent staining and finishing without adhesion problems. Apply to end cuts immediately after sawing to prevent moisture loss and stress cracking. Works on all wood species including exotic hardwoods, pressure-treated lumber, and softwoods. Cleans up with soap and water.

Why Choose Stains & Finishes?
How to Finish Exotic Hardwood Decking
Wait for Acclimation
Let freshly installed boards acclimate for 2-4 weeks before applying finish. This allows the wood to reach equilibrium moisture and the pores to open slightly for better oil penetration.
Clean and Brighten
Apply a wood cleaner/brightener to remove mill glaze, dirt, and oxidation. Rinse thoroughly and let the deck dry for 24-48 hours before oiling.
Apply Penetrating Oil
Brush or pad a generous coat of penetrating oil (like Ipe Oil® or UV Plus) along the grain. Let the oil soak in for 15-20 minutes, then wipe off any excess that hasn't been absorbed.
Seal All End Cuts
End grain absorbs and releases moisture 10-12× faster than face grain. Seal every cut end with end grain sealer within 24 hours of cutting to prevent checking and splitting.
Pro Tip from Our Deck Specialists
Dense hardwoods reject film-forming stains and polyurethanes — these will peel within months. Always use a penetrating oil formula designed for tropical species.
