Guide

Putting-green turf specs and stimp, a real-numbers Arizona guide.

Face height, gauge, backing, UV package, and infill each move stimp — the measure of putt roll speed — in predictable ways. This guide covers what to spec, what to reject, and what stimp target fits which use case. Real numbers, no catalog fluff.

The honest version: The putting-green industry ships a lot of "premium putting turf" that's polypropylene face, latex backing, and untuned crumb rubber infill. It looks fine on install day and produces uneven, slow, inconsistent stimp within 90 days in Arizona sun. The face is the smallest part of a real spec — backing, UV package, and infill are what determine whether the stimp holds. If a spec sheet doesn't call out fiber type, backing chemistry, UV rating, and infill mass, it's not a spec sheet.
01

Stimp targets by use case

  • Family backyard, low-experience: 7–8 stimp (forgiving).
  • Serious backyard practice: 8–10 stimp (member-club feel).
  • Country-club practice green: 9–11 stimp (matched to on-course).
  • Teaching / academy green: 10–12 stimp (tour-prep).
  • Championship / tour-adjacent: 11–14 stimp (specialty install).
02

Face height → stimp (rough guide)

  • 20mm face + heavy infill = 7–8 stimp (forgiving, soft roll).
  • 17–18mm face + tuned infill = 8–10 stimp (member-club feel).
  • 15–16mm PGA-spec face + light uniform infill = 10–12 stimp (tour-adjacent).
  • Exact stimp driven by material + install technique — spec both.
03

Non-negotiable material specs

  • Face fiber: nylon or high-tenacity polyethylene. Never polypropylene.
  • Gauge: 3/16 or 3/8 tight-gauge for putting face.
  • Backing: dual-layer polyurethane. Not latex.
  • UV package: rated for Arizona solar exposure (10+ year fade warranty).
  • Infill: rounded silica or zeolite. Not raw crumb rubber for putting face.
04

Base spec (yes, again)

  • ABC (aggregate base course) — 4–6" compacted in lifts on commercial greens; 3–4" on residential.
  • Never quarter minus. Quarter minus holds moisture, compacts unevenly, produces low spots.
  • Laser-graded to target percolation and drainage plan.
  • Drainage engineered to storm tie-in on commercial; to yard drainage on residential.
05

Infill: the tuning knob

Infill mass controls how upright the face fibers stand — heavier = softer, slower; lighter and uniform = faster, truer. Rounded silica and zeolite outperform crumb rubber on stimp consistency and Arizona heat mitigation. Commissioning is iterative: add infill, brush, stimp-read, repeat until target is hit. A green delivered without documented stimp readings hasn't been commissioned; it's been installed.

06

Common install failures that ruin stimp

  • Quarter minus base — settles unevenly, produces low spots within 12 months.
  • Latex-backed panels — dimensional swings in AZ heat, seam failures.
  • Polypropylene face — flattens fast under sun, stimp drops.
  • Untuned crumb-rubber infill — heat retention, uneven mass, inconsistent stimp.
  • No documented stimp readings at closeout — nothing to hold anyone accountable to.
07

Stimp maintenance over time

  • Weekly brushing to stand fibers back up.
  • Quarterly infill top-up.
  • Annual comprehensive brush + stimp re-verification.
  • Cup rotation on a documented schedule.
FAQ

Common questions.

Stimp is a measure of ball roll speed on the putting surface, taken with a stimpmeter — a ramped device that releases a ball at a controlled velocity. The distance the ball rolls (in feet) is the stimp reading. Tour greens run 11–14; typical PGA member-club greens 9–11; forgiving amenity greens 7–8. Synthetic greens can be engineered to any target in that range.

Rough guide: 20mm face with heavy infill = 7–8 stimp (forgiving). 17–18mm face with tuned infill = 8–10 stimp (member-club feel). 15–16mm PGA-spec face with light, uniform infill = 10–12 stimp (tour-adjacent). The exact stimp is driven by pile height, gauge, backing, infill mass, and how tightly the green is brushed — spec both material AND install technique.

Face fiber: nylon or high-tenacity polyethylene (not polypropylene). Pile height: 12–20mm depending on target stimp. Gauge: 3/16 or 3/8 tight-gauge for putting face. Backing: dual-layer polyurethane, not latex, for dimensional stability in Arizona heat. UV package rated for AZ solar exposure. Infill: rounded silica or zeolite tuned to mass, not raw crumb rubber.

No. AE uses ABC (aggregate base course) under every synthetic surface, including putting greens. Quarter minus is a turf-base myth we actively fight — it holds moisture, compacts unevenly under traffic, and produces the low spots that ruin stimp within 12 months. Read our AE brand rule on this in the site's paver base guide as well.

Infill mass controls how upright the face fibers stand — heavier infill = softer, slower roll; lighter, uniform infill = faster, truer roll. Rounded silica and zeolite outperform crumb rubber on stimp consistency and heat mitigation. Infill is tuned during commissioning by adding, brushing, and stimp-reading in cycles until target is hit.

Weekly brushing to stand fibers back up; quarterly infill top-up; annual comprehensive brush + stimp re-verification. Cup rotation on a documented schedule to distribute wear. AE ships every green with the maintenance cadence tuned to expected traffic volume.
