Should I add the sand first and then rubber, or visa versa?
Preferably, you should put the sand down first and then your rubber. We have found most quarries to be notorious for over-estimating how much sand you’ll need. Better to spread the sand out first, check the depth, then add in the rubber once you are satisfied that you are as close to the 1.5″ recommended sand depth and that it is spread as evenly as possible. Tip: consult with your local contractor about the possibility of having your sand “laser graded”. Laser grading eliminates the guesswork in spreading material, and often pays for itself with the time-saving attribute alone!
