I noticed that your technical info gives a coverage rate of 100-200 square feet per gallon. Does that mean 100-200 sq.ft. per coat -- or is that for the required two coats? I'm doing a deck and railings totaling about 650 sq.ft. and am wondering how much stain to buy. (Deck is weathered and neglected about 25 yrs. old -- not smooth, new wood, so stain will probably really soak in.)
First coat applies at 150-200 sq feet while the second coat applies at 200-300 sq. feet. It averages 100-150 sq. feet for 2 coats. You will nee 6-7 gallons for the two coats.
