Coves, curbs and terminations: where a traffic coating ends
The office-park coating crew reaches the first row of columns. A taped line is visible, but nobody can identify the detail that sets its height. The adjacent door threshold is lower than expected, so copying that line around the whole level could conceal an unresolved interface.
Treat every edge as a located interface between the coating and adjoining work. The cited instructions distinguish wall transitions, sealant details and other terminations for their particular assembly. The project’s current detail and finished levels determine what belongs at your column or doorway. An attractive continuous line is not evidence that all those conditions have been resolved.
Establish the edge before repeating it
- List the interface types. Mark walls, columns, curbs, thresholds, exposed slab edges and other boundaries on the zone plan. Attach the applicable detail reference to each type. Keep drains and designed movement joints linked to their own coordinated details rather than forcing them into the wall treatment.
- Check the adjoining finished work. Confirm relevant levels, threshold conditions, finish build-ups and receiving surfaces with the responsible trades. Record differences from the detail. Do not use an assumed future topping level to set today’s termination without the required confirmation.
- Confirm the actual components. Have the technical lead identify preparation, sealant, reinforcement, detail coating and termination materials where specified. Verify their sequence and compatibility through approved documents. A cove drawn in one system does not establish the same material arrangement for another.
- Review representative conditions. Agree which trial interfaces show the ordinary condition and important exceptions. Locate and record the review at the required stage. One column trial cannot settle a lower doorway or a different exposed slab edge merely because both involve a coating end.
- Keep concealed-stage evidence. Record the located detail work and required checks before the wear or finish layer hides it. Pair an overall view with a useful close-up and reference. Mark incomplete or questioned interfaces separately so a clean finish photograph does not replace the missing stage review.
- Release repetition within its limits. Give the crew the current accepted reference and the exceptions needing decisions. Coordinate protection and adjoining finish work. When a new condition appears, refer it rather than extending the trial’s acceptance beyond the interface it actually demonstrated.
Common mistakes
- Setting every upturn from one unexplained taped line.
- Assuming the next trade’s finished level.
- Photographing only the top coat after detail work disappears.
Checklist
The edge-detail record
- Located interface and current reference.
- Confirmed adjoining finished levels.
- Approved component and sequence information.
- Representative trial with clear limits.
- Concealed-stage evidence and exceptions.
- Current instruction for repeating work.
Check your understanding
The column trial is accepted, but the nearby door has a different threshold level. Can the crew copy the column height there?
