Rake marks and rough surfaces come down to the same root causes: machine condition, tooling match and technique. Start with coarse 30/46-grit stage metal-bond discs on a walk-behind grinder, work the whole deck, then progress through 80, 150 and optionally 300-grit stage resin pads. Diamond abrading removes the thin, weakened laitance and sharp surface layer that catches bare feet, leaving a level, even, anti-slip surface.

Aggressive exposed aggregate, weathering, and efflorescence make the deck surface feel like sandpaper under bare feet.
Getting this part right saves a full re-pass later.
What you should know before starting.
A common starter set on a Husqvarna-style equipment is a coarse metal disc such as a Husqvarna single-bar segment disc at 30 grit stage for aggressive stock stripping, followed by 60/80 grit stage to begin flattening.
Use a 270-580 mm planetary or single-disc walk-behind grinder matched to your plate system.
Contractors who skip this stage usually end up redoing the floor.
The key points in practice.
Abrade in overlapping 30-40% passes, keeping the equipment moving.
This is where most crews get it right - or lose time.

The key points in practice.
Fill cracks wider than 3 mm with a flexible concrete caulk, and fill popouts with a fast-setting cementitious material patch, letting it cure 24 hours before abrading.
This is where most crews get it right - or lose time.

Whichever equipment you rent, confirm the plate system matches your discs (Husqvarna Redi-Lock, Lavina, WerkMaster, etc.) before leaving the yard.

This is also the moment to round sharp control-joint edges slightly so they do not catch bare feet.

A: For most jobs, No — if you stop around 150-300 grit stage and use a non-slip additive in the sealing layer, the deck stays grippy. Stop at 50 grit stage if you want a more aggressive texture; go beyond 300 grit stage only indoors.
A: In short, In most cases 0.5-1.5 mm is enough to take off the coarse layer. Do not abrade deeper than 2 mm on a thin residential slab, or you risk weakening the top.
A: The practical answer is, For a small deck, yes with a cup wheel, however you will leave swirl marks. Renting a walk-behind grinder gives a level, even outcome and is far faster.
A: For most jobs, Wait until the deck is fully cleaned and the sealing layer has cured (in most cases 24-48 h). Wash away grinding slurry before it runs into the pool.
