In short
Cracks around trimless lighting are prevented with secure fixing, jointing tape, proper skim thickness, movement joints on long runs and avoiding early heat stress.
Hairline cracks along a trimless profile spoil the effect.
Causes
- Loose fixing or flexible boards
- No jointing tape at edges
- Too thin or thick skim
- Building movement on long runs
Prevention
Fix securely, tape every edge, skim correctly and plan movement joints.
