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 both Powder Coated & Non Powder Coated ModWood Clips?

For all ModWood clips


What type of fasteners are required to fix the clips to the 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 many fasteners are required per clip?

he KT88 requires one fastener per board space (6 per clip) and

the KT137 requires two fasteners per board space (8 per clip).


What Joist types are suitable for the KlevaKlip Top-Fix Clip?

Treated Pine, Kiln dried Hardwood, Metal RHS or C Purlins are suitable for use with the KlevaKlip System For Laminated Veneer Lumber (LVL) joists please check with your supplier for suitability. F14 unseasoned hardwoods are not to be used due to their high shrinkage rates.


What size gap does the KlevaKlip provide between each of the Deck Boards?

Modwood Composites will provide a gap of around 4mm when using the KlevaKlips. This gap may vary over time in different climatic conditions.


What dimensions are the KlevaKlip's?

KT88 Top Fix Clips L 535mm x W 60mm
KT137 Top-Fix Clips L 568mm x W 60mm


What height are the Klevaklips?

The thickness of the metal is 1mm and the nipples/ridges are around 2mm in height= Total 3mm


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


Lineal Meters of decking boards

Total Lineal Meters divided by 11 x 4.5 KlevaKlips per Square Meter
Example: 300 Lineal Meters of Decking divided by 11 =27.27 X 4.5 =123 KlevaKlip's


What adhesive is recommended when fixing ModWood deck boards to the KlevaKlip's?

Inex>Bond, Fuller Toolbox, Sikaflex 11FC,Selleys 3 in 1,Selleys Liquid Nails High Strength.


Approved Adhesives For KlevaKlip

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 4mm 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 the KlevaKlip KT series Top Fix clip directly fixed to concrete or tiled areas?

No, KlevaKlip KT Series 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.

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.
