We are completely remodeling a 1985 beach condo with a plywood subfloor. We purchased Home Depot's beautiful Allure Plank to install in the entire condo (including kitchen & baths). We removed the carpet & tile and there are uneven places in the subfloor, in addition to some water damage to the subfloor (currently dry). Also, some of the sheets of plywood are screwed in and others are stapled in. The staples are not level with the flooring and we are concerned that this might damage the floating vinyl flooring. It appears that this flooring will be very easy to install (part of the reason we purchased it), but we want it to last & want to be sure that we prepare the floor properly. Unfortunately, there aren't any instructions with this flooring regarding floor prep. Can you please give us some recommendations to ensure that the end result is not only beautiful but durable. Thank you!
