Some common mistakes to avoid when laying 19 x 90 decking planks.
The most common decking planks we supply are 19 x 90 in size. On occasions, decks are not installed correctly leaving customers frustrated. Here are some tips to avoid future decking installation problems.
- Substructure must always be sufficiently raised off the ground and preferably above a permeable surface so water does not collect in puddles underneath.
- Noggins should be used to keep the stringers square and rigid while gum poles can be used to help carry weight and prevent bounce in the deck.
- We suggest using a 2 to 3mm gap between slats for 90mm planks and 6 to 7 mm gaps for the wider 140mm plank (there will be some expansion & contraction depending on the season).
- Proper spacers should be used not only to ensure constancy of the gaps used but also to pull the planks perfectly straight.
- There must be at least two stainless steel screws per fixing onto substructure at 450 spacing.
- The holes for the screws should be predrilled (otherwise decking ends will split), and the screws should be counter sunk.
- The stainless steel screws should be ideally a 5×50 or 5×50’s.
- Decking; especially Garapa (cement stains Garapa) should be regarded as a finishing product so do not install it if cement or any other labour work is still to be done in the area.
- Oiling of a deck can increase the stability of your deck over time.
