4 Easy Tips to Minimise Cupping in Decking

In Queensland’s hot climate, decking boards that get full sun exposure are prone to drying out on the top which results in them cupping. To help minimise this it is recommended to:

1. Limit board width to 80 – 85 mm cover width.

2. Finish with a very pale coloured stain or paint i.e. light grey

3. Provide good sub-deck ventilation, particularly if it close to or on the ground

4. Use the correct fasteners (nails/screws) for the timbers being used – both joists and decking
