We have a 450 sq.foot "utility" area (ground level, not a basement, but it is where our HVAC, water heater, laundry, freezer, storage, exercise equipment is). Floor is slab concrete, walls cement block. 45 year old home, original contractor cheap tiles over the years have loosened and the remaining ones are easy to pop up. We do not have ground water or dampness problems in this area. We have gotten so much advice from friends, coworkers, home center folks that I need kind Metafilter folks to steer us to solution for our snowflake needs. Details inside.
The remaining adhesive residue does not seem thick, and home center person said we could use long handle blade tool to scrape, then apply a primer coating with self-stick resilient tiles that are the thicker type squares (that can be butted or spaced for grouting) since the thickness will prevent the concrete roughness from being visible in the vinyl surface.
But I also see this
interesting video about non-square resilient flooring that are floating and (unlike snap together plank flooring) they adhere via overlap adhesive. Wouldn't that save us the scraping up of the old residue?
People also warn us about this utility area flooding (overflowing washer, hot water heater leak) and the water getting under a floating floor and molding. But this is concrete slab and vinyl, right, and if the water could get between couldn't it also evaporate out over time? And except for sheet goods you would always have that danger in a utility area, right?
Estimate from a contractor to sand, seal and stain was $1700 (over $4/sq.ft) plus we worry how much dust they might create. We are willing to do the job ourselves, unless that is unwise. We are most concerned about not picking a solution that is just plain wrong for the application, than about beauty. But cost or value counts too of course. We could afford the $1700 range if we knew we were spending it wisely.
My Googling and Metafilter search turned up plenty of advice on flooring, some old, some on the floating plank floors which would be totally inappropriate for this area, or on ceramic or other more expensive solutions. But I think my problem is a "which to do" as opposed to a "how to do". Thanks in advance everyone!
