Can you lay new astroturf on top of old astroturf?

Yes, you can lay new astroturf over old astroturf, but it's important to ensure the existing surface is clean, dry, and in good condition. Any uneven areas or damage in the old turf should be addressed to prevent issues with the new installation. Additionally, proper drainage and stability should be evaluated to ensure the longevity and performance of the new turf layer.
