What do you feel is the "best" way (or combination of ways) to apply Ready Seal as far as efficiency of product consumption, speed, and good results?
Sorry, hands down the best way to apply ready seal is a deckster deck sprayer. They can do it in half the time of any pad or roller easily and they don't create that cloud of death like airless sprayers do.
I use the adjustable gun cone spray tip at 75psi but I adjust the pressure down at the gun. Spray shield near the house and a flag/tarp device I created for the rails. I van usually seal a 400 sqft deck in 20 minutes.
