Really improved the place
Installed Diamond Grid-Loc floor over an asphalt base floor, and I am being generous in calling it a floor. It was uneven and dirty but after a bit of sweeping and blowing clean with a leaf blower I had it to the point I could cover it over. The tiles went down fast and neat. Because of the pattern that I wanted, needed lead-in lines for the landing gear, I had to modify the sequence for putting the tiles down from the recommend procedure but all went well, very well. Brightened up the place immensely, looks great, works great! Very happy with the outcome. The only additional advise I can give is this, the diamond pattern is very aggressive on your knees and hands, if you plan to be down on your floor working on a project think about using the Coin Grid-Loc tiles instead. Much more human friendly for the long term. Since my floor will get damp to wet at times I am happy with the additional traction the diamond pattern will give.
