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.
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).
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.
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.
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.
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.
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.
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.
