How to build a deck with Modwood

KlevaKlip ModWood Install Video

Proper planning of your deck is critical to the final result.

Make sure your deck is even when you lay it out ready to put the boards on. Getting your first boards laid correctly will ensure the result is a great looking deck.

This video shows you the best way to assemble and connect your timbers using the KlevaKlip method.

Using KlevaKlip ensure no unsightly nails or seams will be visible and your deck will look professional and seamless.

Things to remember:

  • Make sure KelvaKlips sit squarely on the outside joists when positioning the overhang for the front full deck board and fascia.
    Note: the recesses on the sides of the clips are set at a width of 45mm to assist with positioning the clip squarely on standard 45mm joists.
  • Full deck board widths are recommended at the front of your deck and once this is obtained, place your other KlevaKlip's on the end joists towards the house to check squareness of your deck and to ensure the last deck board width against the house is not too narrow.
  • If you are using stainless steel clips, it is essential that you use stainless steel fixings.

Using Lysaght Firmlok Steel Joists


For fixing onto steel joists, although it is not mandatory, we believe a good practice is to apply a thin coat of adhesive to the top of your joists prior to laying the clips. This will give your joists better protection against Corrosion.

Tip: Putting a barrier between the joists and the clips is absolutely essential if you are using stainless steel clips onto galvanised joists.

Note: The special "knuckle nails" will not penetrate steel joists. Therefore before fixing the clip onto steel joists, simply turn it upside down and simply knock the knuckle nail straight.

Important Information

  • It is essential to read and follow the steps listed in the "How To" Fixing Instruction manual prior to installing the KlevaKlip system
  • Please ensure all the KlevaKlip's are clean, sound, dry and free of oil or grease. Thoroughly remove all loose particles and dust prior to fixing.
  • KlevaKlip is not suitable for non-square decks or irregular joist heights
  • The KlevaKlip Top-fix clip is designed to suit Timber and metal joists RHS 35- 50mm or larger in width.
  • Whilst the fixing of the boards into the KlevaKlip is fast and will save time over conventional hand fixing, it is important that extreme care is taken in installing your first row of KlevaKlip's. This will govern the straightness of your deck.
