What can I use on Masonite on a skateboard ramp to help protect from weather

Hello Cdog,

A Spar Urethane will give you the best protection. The paint protects against the sun, seals against rain and moisture, and expands and contracts with seasonal change.

Since riding a skate board is going to be rough on any surface I recommend checking the condition of the paint at least once a year. This will help make sure that the ramp stays protected. I hope this helps.

Cheers,

Chris
