Last night I used euco diamond hard on my new concrete floor. The floor was smooth, power trolled, a very nice finish. I applied the diamond hard with a deck stain sprayer and the temp was ~70'F. I moved the liquid around on the floor vigorously with a stiff broom. It seems like it soaked in but at each area where one pass met the next (I did about a 4 foot section at a time) there is a line. 12 hours later the line is still there. Why did this happen? Will it lessen in time? Would an extra coat help?
