Cove, details, drawings, and takeoff units
The edges of the floor are the job. Units must never get mixed.
- Explain integral cove vs. stick-on base
- Protect SF vs LF vs EA on every document
- Know when a shop drawing is required before an application
Why cove is not trim
Integral cove is formed with the resinous system so the floor and wall base are one. Height (often 4–6 inches, sometimes more), radius, and termination (reglet, cap, or into wall panel) are specified. Stick-on vinyl base is a different product and usually wrong for washdown rooms. Tank pads, equipment pads, drains, trenches, and door thresholds each need a detail. If the drawing is silent, we RFI — we do not invent.
Units you will live in
| Unit | Used for | Common mistake |
|---|---|---|
| SF | Field of floor | Forgetting deductions at pads or pits |
| LF | Cove, joints, terminations, trenches | Mixing with SF on POs and bills |
| EA | Drains, targets, tests, mockups, samples | Leaving them off the SOV |
| GAL / kit / drum | Material | Ordering by SF without waste and thickness |
Takeaways
- Details are where profit hides and where failures start.
- Never convert cove LF into floor SF in your head.
- No drawing, no application on complex transitions.
