Excellent quality control
St. Charles, IL
I just finished installing a 22 X 24 ft garage floor (light and dark grey tiles). It took about 4 hours to install the whole pieces and another 3 hours to make and install the edge cuts. I used the center-cross method to start the installation and simply filled-in the quadrants. Each tile fit perfectly with its neighbors. And, there were NO defective tiles.
I found that cutting 7mm samples with a utility knife was extremely difficult and, therefore, dangerous. I contacted customer support and was told that another option was to use a shear cutter. I bought one on Amazon for about $130. I may never use it again. But, it was the right tool for the job.
One caution. In extended, direct sunlight, the darker tiles will expand and buckle. The dark grey tiles at my open garage door rose about 1/2 inch off the floor after an hour in the sun. However, after closing the door to block the sun, the tiles returned to their normal dimensions in about 20 minutes. This is manageable.
I highly recommend this product and the company's customer service.
