6. Dressing the Sub-Base
(Optional)
After the sub-base has hardened, take the landscaping
rake or the backside of a regular rake and gently remove
stones sticking above the surface of the sub-base.
Sweep the loose stones off of the sub-base. You
will find areas where the sub-base has pits, etc. from
the stones being removed. Add small amounts of
30-35 grit sand and lightly spread it in those areas
before laying the putting green on the sub-base.
The sand will fill in the holes and make
the bottom of the artificial putting green smooth.
