Q: We have just sandblasted the underside of our redwood deck to remove all of the paint the previous owner used. We now want to seal and preserve it so it won't have to be done again for 10 years.
The deck is on the east side of Lake Tahoe with full sun on the top. It is about 30 feet off the ground and the underside gets no direct sun. Moisture is a problem due to snowmelt.
