Frequently Asked Questions
Do I need to add an oil finish or topcoat to my floors after applying the lye?
Yes. Wood Lye is not a finish. Lye-treated wood remains unfinished and must be sealed with an oil finish such as Diamond Oil Active or Master Color Oil for protection and durability.
Do I need to neutralize the lye?
For Oils, reactive lyes, like Antique and Driftwood Lye should be neutralized with Intensive Wood Cleaner prior to oiling.
For Waterbased Finish, all lyes should be be neutralized with Intensive Wood Cleaner prior to finishing.
Should I apply more than 1 coat of lye?
One coat is sufficient when applied according to the recommended coverage rate.
Why does the lye look uneven and splotchy after finishing with oil?
Can I mix or layer lyes?
Can I use Wood Lye on Pine or should I use Softwood Lye?
Wood Lye can be used on Softwoods like Pine; it has a milder effect than WOCA Softwood Lye.
