Outline:
- What engineered timber actually is (real timber wear layer over plywood core)
- Wear layer thickness — the deciding factor (2mm+ usually OK, under 2mm not)
- How to check what you have without lifting boards
- Difference between engineered and laminate (laminate can’t be sanded at all)
- Number of times an engineered floor can typically be sanded
- What happens if we sand and hit the plywood layer
