Pressured treat fine deck which was sanded to bare wood will be treated with 1500 dark oak stain. Will I need 1 or 2 coats for 875 sq. ft. and how many gallons?
You should use the kit to prep the wood after the sanding. This will remove any sand dust and help the stain to penetrate deeper. Only one coat this time as two coats may not soak in properly after heavy sanding. You will need about 5-6 gallons for one coat.
