It’s so fast and easy to apply, it doesn’t really matter. Apply small amount to applicator, apply in small sections (2ft x 2ft) wait 90 seconds, wipe off. It sure makes everything look good and so much nicer to wash. Try to keep it out of the elements for several hours to a full day to let it cure.
