Pre-purchase checks and compatibility
Confirm that the 148mm width and 18mm thickness suit your project design and intended span. Check that your workshop or site has adequate storage for a 5.49 metre length, and ensure you have appropriate cutting equipment (circular saw, table saw or hand saw) to cut the board to your required dimensions. Verify that your finishing schedule (paint, stain or veneer) is compatible with primed MDF surfaces.
- Measure your project space and shelf span requirements
- Confirm cutting and assembly tools are available
- Check storage space for a 5.49m length before delivery
- Plan your finishing schedule in advance
Installation and finishing preparation
The board arrives primed and ready for further finishing. Before installation, allow the material to acclimatise to your workshop environment for 24 to 48 hours. Inspect the length for any damage in transit. The primer provides a base coat, but you should sand lightly with fine-grit paper and apply your chosen topcoat (paint, stain or veneer) before final assembly. Ensure all cut edges are sealed with primer or paint to maintain moisture resistance.
- Allow acclimatisation time before cutting and assembly
- Inspect for transit damage upon delivery
- Sand primer lightly before applying topcoat
- Prime or paint all cut edges to protect against moisture
