One of our contractors recently installed a (roughly) 500 square foot patio using Techo-bloc's Blu 60 in the Sandlewood color. For most contractors, one of the final steps to finish this project would have been the installation of polymeric sand into the joints between the pavers.
Problem: it was supposed to rain later in the afternoon on the day that the job was supposed to be finished. (With regular poly sand you cannot apply it when it is going to rain.)
Solution: EasyPro joint stabilizer by Unilock. Not only can EasyPro be applied when it is going to rain, but it is actually applied with water!
The whole joint stabilizing process took about 1 hour to finish the 500 sq ft patio. Here are some pictures from the job:
