Modwood - Frequently Asked Questions


How Does the KlevaKlip Work?

KlevaKlip is a multi-board concealed fixing system, working on a "fixed pitch" principle, that provides consistent gapping of the boards. As each board is inserted into the KlevaKlip, it tightens the previous board, providing significant holding power of the board into the clip. This mechanical holding is supported by the use of adhesive to provide a look, longevity and feel that is difficult to obtain with conventional fastening systems.

Where can I see images of Snap-LOC clips and both Traditional Powder Coated & Non Powder Coated ModWood Clips?

For all ModWood clips


What type of fasteners are required to fix both clips to Timber or Steel joists?

Timber joists use 8 gauge 25- 30mm Button Head Galvanised screws with a head size less than 2mm or Galvanised Connector Nails 32mm x 3.15. Metal joists use 10 gauge 18mm wafer Head galvanised self drilling screws with a head size less than 2mm or equivalents can also be used. When using Stainless Steel clips, it is essential that you use stainless steel fixings. Use counter-sunk heads if button heads are not available.

TIP: Time saving benefits can be achieved by utilising Coil Nailer gun to secure the second and subsequent rows of KlevaKlip's into timber joists

How do I calculate how many KlevaKlip's I will require for my deck?

There are three methods you can calculate your Klevaklip numbers or use the Modwood Decking Calculator that calculates how many Modwood deck boards, KlevaKlips, Adhesve & fasteners to be used on your deck
ModWood Decking Calculator


Per Square Meters (PSM)

Coverage 4.5 KlevaKlip's = Approximately 1 Square Meter
Example: 20 Square Meter Deck X 4.5 = 90 KlevaKlip's


Square Meters of Deck Per Box of KlevaKlips

Top Fix Clips (40 Clips) 9 Square Meters


What adhesive is recommended when fixing ModWood deck boards to both types of KlevaKlip Clips?

Snap-LOC Clips

Any Polyurethane-based MS-type outdoor adhesive is acceptable

Traditional Metal Clips

HB Fuller Toolbox Original, Sikaflex 11FC,Selleys 3 in 1.

Can Klevalip be used for screens?

Whereas it is quite common for privacy screens to have a gap between the boards of 12 - 20mm, the KlevaKlip system provides a maximum gap of just 4.5mm between boards. In a screening situation with the wind behind the screen, such a small gap can effectively cause the screen to act as a "sail". This can generate substantial pressures on the boards/screen - in very strong winds, this pressure can be in excess of 200kg/sqm.

Inserting boards into clips at height can be quite awkward, particularly without adequate manpower or stable footing. In a worst case scenario, this can cause significant "tearing" along the side of the board during insertion into the clip, thus significantly reducing the holding power of the clip.

Given the above information, KlevaKlip Systems P/L do not recommend the use of KlevaKlip products for screening when the screen is subject to wind velocity from behind the screen of greater than 40 km/hr, or when the screen is greater than 2.4m in height. In such instances "face fixing" of the product with screws or nails should be done.


Can Klevaklip be used in ceiling situations?

Due to the difficulties in fully supporting boards whilst they can correctly be inserted into a KlevaKlip, KlevaKlip Systems P/L does not recommend the use of KlevaKlip products in situations of ceilings and soffits.


Can I fix both types of KlevaKlip's directly fixed to concrete or tiled areas?

No, Both Snap-LOC and Traditional Metal KlevaKlip's cannot be directly fixed to concrete or tiled surfaces. Battens made from Treated Pine, Steel or aluminium with an absolute minimum of 50mm in height and approximately 50mm in width can be fixed to the concrete or tiled surface to aid ventilation to your deck and substructure. Battens should run in the direction of the fall of the concrete or tiled surface. Avoid closing in any sides or ends of your deck to aid further ventilation.


Can I use Snap-LOC clips in Bushfire-rated areas?

No, Metal clips should be used

What type of clips can I use in Coastal regions and around salt or chlorinated swimming pools?

The Snap-LOC clip fits all environments. If you are in a Bushfire-rated area Stainless Steel clips must be used.

How can I remove a ModWood Board from the KlevaKlip?   

You can remove the boards as long as you have access at one end of the board. You will need to break the adhesive bond between the clip and the board with a stanley knife or similar tool. Next step (2 people preferable) down each side of the board you will see the uprights which hold the board into the clip- You need to prior both uprights apart with a knife, screwdriver or similar tool whilst  lifting the board up vertically. You will need to do this at each upright approximately 450mm centres.

To replace board clean of the adhesive from the clip, replace adhesive and engage board into clip.

Further information about engaging the board into the clips can be found on our web site

My galvanised clips have some rust spots on the edges - should I be concerned?

No - it is typical that some minor surface corrosion appears on the cut edge of galvanised products. The galvanising is still chemically bonded to the surface of the steel, therefore, provided you have installed your clips in line with the KlevaKlip Corrosion Resistance document, your surface corrosion will remain of a cosmetic nature and won't affect the performance of the clip.
