I'm looking to upgrade our garage floor and have looked at racedeck and its competitors, the rolled flooring options, and epoxy coatings. I happened to be in Costco today and noticed that they have floating wood grain laminate flooring with attached pad for $1.69/sq ft. That's a very competitive price, but is their a reason why this would be a bad idea for a garage floor?
Whats primary use of the garage? Jacks, welding, grinding, etc will destroy it. Parking cars may de-laminate it similar to hot tire pickup on epoxy or the force of moving the car after time will pull apart the clicklock joints. The low cost stuff is just a picture of wood on top of cardboard with foam on the bottom.. Moisture will destroy, you would need a good sealed vapor barrior underneath for sure. Wet cars, snow/ice on cars, or water seepage under the garage doors will also destroy it.
I've seen this stuff fall apart in houses under normal living in just a couple years.. There are quality ranges of course, and poor installation that can add to the issues.
Not garage related but:
My favorite was a store demo at a high end flooring place when I was building my house and shopping for real site finished hardwood. The salesperson took a piece of $7sqft engineered wood floor, and gave the speech about it won't mold, split, warp, or scratch. And then said real wood ***** because it will scratch and dent moving furniture or dropping items, then pulled out a car key and starts to scratch the sample board looking at me saying 'see this stuff is scratch is proof, I'm trying to damage it and I can't, so normal use will never hurt it' well needless to say when I looked down the board was scratched all to hell... The awkard silence in the store was awesome. I held off and put in carpet til I could do more research, and will be doing real site finish on my own one day..
