Q: Can it be used on green treated lumber

Pressure treated lumber has to be dry.

Q: Can you use a regular wood stain after applying?

Yes the clear MARINE can be painted or stained. Or you can purchase a tint for SEAL-ONCE and use the MARINE as a sealer and stain. MARINE Features: • Clear formula can be painted or stained after treatment • Tinted formula provides additional UV protection • Available in 11 semi-transparent tint colors • Eco-friendly, Non-toxic; will not harm pets, plants, people or marine life • Ultra-low VOC, Water based • Can be applied around or over fresh or salt water • Flexible, breathable barrier, Stabilizes & protects wood • Prevents warping, cupping, wood rot & decay • Resistant to salt water spray • Prevents mold, mildew & algae growth • Soap and water cleanup

Q: I want to use this on a 6x6 wood beam at the opening to my walk-in shower (floor to ceiling). No direct shower spray. Will this seal it?

Yes you may use it for this specific application. As suggested in a comment down bellow, you would want to make sure that it is fully cured before using the shower. Typically it would take 48 hours to cure but it may take longer depending on the environment.

Q: does this work for the interior of a sauna , safe to sit on?

It dries to a hard, smooth finish, is non toxic and nice to look at. Would be safe to sit on...other types of recreation may require caution.
