Mark what must be removed and what may remain
Close and wide photographs distinguish loose edges from sound coating and show where scale thickens around joints or wet areas. The repair or coating team identifies material that may stay. A marked trial establishes an achievable finish before the same method is extended across the work face. Coating and scale removal can then continue without treating every patch as identical.
Agree what stays and what comes off
- Substrate and known weak or damaged areas.
- Existing coating, scale or contamination.
- Sections to strip and sound material allowed to remain.
- Containment for water, fragments and fine residue.
Trialling the method before full removal
Condition can change across one work face, with sound coating beside loose edges or thicker scale around joints. A marked trial gives the inspector or following trade a real surface to compare with the required finish.
The accepted trial method extends across the marked area while water and fragments are contained. The prepared surface is compared with the finish needed by the next treatment.
Our surface preparation service covers the work itself. If you are still defining the method, the note on jetting pressure and flow explains why substrate and deposit both matter. Send close and wide photographs for review.
Questions about removal limits and the prepared surface
Removal limit. The job details state whether sound coating may remain. The trial shows how both the coating and substrate respond before the marked area is extended.
Work inside equipment. Openings, geometry, isolation and recovery must allow the tool to reach the scale and return loosened material.
Handover for recoating. The coating contractor sets its acceptance condition and timing for the exposed surface and expected environment.
