How Stone Ridge reads

Stone Ridge is the lightest of our four gray blends. About three of every four chips are light (light granite gray, pale gray or white), so from standing height the floor reads as a soft, cool stone gray. Up close, the graphite chips give the pattern its definition.

There is no black chip. The darkest color is graphite, a blue-leaning dark gray, so the contrast is real but gentler than in Checkmate, where black sits right next to white. Graphite and pale gray both lean cool, which keeps the floor crisp rather than creamy.

Where Stone Ridge works

  • Garages, basements and shops that need light. A light floor reflects more of the room's light than a dark one, which helps in a space with few windows.
  • Workshops. Dark bolts, nuts and hand tools stand out against a light floor instead of disappearing into it.
  • Show garages, home gyms and finished basements, where the floor stays fairly clean and a bright, calm look matters more than hiding dirt.
  • Cool interiors. It pairs with white walls, gray cabinets and daylight-color LED fixtures.

Will Stone Ridge show tire marks?

Yes, more than our darker blends. With no black chip, dark rubber marks and grime stand out on Stone Ridge sooner than on Gun Metal or Midnight Granite.

The other side of that trade is light dust. Sawdust, drywall dust and dried road salt blend into the white and pale gray chips. For a daily-driver garage that tracks in a lot of mud, a darker blend is the easier floor to keep looking clean. For a shop where dust is the main mess, Stone Ridge works in your favor.

Full or partial broadcast: which base coat goes under Stone Ridge?

Stone Ridge works as a full broadcast or a partial one. At a full broadcast the chips are the floor, and the base coat should match one of the light chips (light granite gray or pale gray) so thin spots disappear.

At a partial broadcast, the base coat shows between the chips and becomes the floor's main color. A light gray base keeps the floor bright. A base tinted to the graphite chip makes the light chips pop and gives the floor more contrast. The flake guide covers how to choose between full and partial broadcast.

Matching an existing floor

Stone Ridge is comparable in color to Gravel (Torginol). Gravel also reads as a light, cool mix of grays and white with no black chip.

Before you extend or repair an existing Gravel floor, make a sample board from our chips, set it on the old floor under the room's normal lighting and compare. Email Adam with the floor's details before you order.

How much Stone Ridge to order

The broadcast style changes the order more than the floor size does. A 400 sq ft two car garage takes 2 boxes at a full broadcast but only 1 box at a heavy partial broadcast.

Floor Full broadcast Heavy partial broadcast
400 sq ft two car garage 2 boxes (67 to 80 lb) 1 box (8 to 16 lb)
704 sq ft three car garage 3 to 4 boxes (118 to 141 lb) 1 box (14 to 28 lb)
1,500 sq ft shop or basement 6 to 7 boxes (251 to 300 lb) 1 to 2 boxes (30 to 60 lb)

Full broadcast figures use the typical rate (0.167 lb per sq ft) and the planning rate (0.20). Heavy partial uses 0.02 to 0.04 lb per sq ft. These rates come from published manufacturer guidance and are typical, not guaranteed. Every box is $85 before freight. Size your floor in the flake calculator.

Questions contractors ask

What colors are in Stone Ridge flake?

Four colors at about 25% each: light granite gray, graphite, pale gray and white. There is no black chip, which is why the blend reads light.

Which existing color is Stone Ridge comparable to?

Gravel (Torginol). We list the reference only so you can match a color. Pro Surface Supply USA is not sponsored or endorsed by Torginol. Before you extend a Gravel floor, set a Stone Ridge test board on it and compare the chips in that room's light.

Is Stone Ridge too light for a garage floor?

Not if the trade-off suits the garage. It shows dark tire marks and mud sooner than a darker blend, but it hides light dust and makes dropped parts easier to find. For a garage that sees heavy mud, a darker blend such as Gun Metal or Midnight Granite is easier to keep looking clean.

What base coat color goes under a Stone Ridge partial broadcast?

A gray taken from the blend. A light gray base keeps the floor bright, and a base tinted to the graphite chip gives more contrast. The base shows between the chips, so it sets the overall color of the floor.

How much Stone Ridge do I need for a partial broadcast?

Usually one box. At heavy partial density, a 44 lb box spreads over roughly 1,100 to 2,200 sq ft, so even an 864 sq ft three car garage needs at most about 35 lb.

Is Stone Ridge a warm or cool gray?

Cool. Graphite and pale gray lean slightly blue, and there are no tan or cream chips. For a light floor with a warm cast, compare Canyon and Coastline.
