Thank You

Can Decktec be used with composite boards?

Yes. Although most composite systems have their own fixing options, there are still plenty of profiles that require traditional top fixing. So long as the boards are within Decktec’s size range, Decktec is an essential addition for getting the boards down straight and fast.

Can Decktec straighten bowed boards?

Absolutely. In fact, Decktec will guarantee the fixed spacer which has been tested to 1200kpa will not fail even with a bowed 140 x 28mm board.

Can you use the Decktec Decking System on Steel Joists?

Yes, Decktec’s deck strips will fit a 50mm steel joist section. As it is recommended by manufactures to install a membrane between timber and steel, Decktec’s deck strips may be positioned with a button head screw, Decktec recommends BUILDEX Smooth Top Teks®

How does the Decktec Decking System deal with variation in timber widths?

The patented removable spacer compresses to accommodate oversized boards, as well as the 1mm sacrificial ridges on the fixed spacers. Any undersized boards will need to be nudged to even out the gaps.

How thick is the Decktec Deck strip?

The base of all Decktec’s products is 2mm thick.

How do you “boarder off” using the Decktec Decking System?

The border may be set out in the same traditional manner. Decktec suggests using the Tear-Away strip under your boarder boards to ensure the surfaces finish flush.

How do you finish the last board’s when using the Decktec Decking System?

With Decktec’s Tear-Away strip, you have the option to lay the Tear-away strip to accommodate the last few boards (depending how much area you need to make up) allowing you to creep the spacers. Alternatively, run the deck strip all the way to the end and scribe the last board.

Should I lay my boards in pairs?

Yes, laying boards in pairs either side of the removable spacer ensures progressively maintaining a straight deck every time with the fixed spacers doing their job in correcting bowed boards.

How do I set up using the Decktec Decking System?

Determine the position of the leading board, set and fix Decktec’s deck strip on the two outermost joists. Run a stringline or laser between the two and fix off the deck strip’s on the remaining joists keeping straight to the line.

How do you join the ensuing strips to ensure a watertight finish?

Position the adhesive joining pads (supplied in the accessory pack) sticky side up at the centre of the join. Continue with butting the next Deck strip into position. Continue this process until the full length of the joist is covered.

How wide is the spacer?

The spacers provide 5mm gaps for the 86mm and 90mm range, and 6mm for the 140mm, 135 and 136mm range. Decktec does not recommend smaller gaps than this as they are more likely to trap debris and dirt, and timber also needs room to swell with seasonal changes, with some species more than others. Insufficient spaces can lead to binding resulting in cupping or even popping off the joist.

What size joists does Decktec suit?

Deck strips will cover up to 50mm wide joists.

How long are the strips?

86mm Deck strips are 1092mm, 90mm Deck strips are 1140mm, 135mm Deck strips are 1132mm and 140mm Deck strips are 1168mm. Please note the 135mm system will work with 136mm boards.

What is the product made of?

100% recycled polypropylene. Decktec is UV stabilised. Made in Australia to handle the harshest conditions.

How many fixings do I need to secure deck strips to the joists?

Generally, Decktec would recommend three clouts evenly spaced. In temperature variations throughout the day the Deck strips may rise between fixings and contract as it cools down again, this will not affect the function of the Deck strips. In environments with variations over ten degrees, Decktec recommends an additional fixing at both outer ends.

How many Square meters does a 24pk carton cover?

Approx. 12.5m2

How many Square Meters does the 6-pack cover?

Approx. 3.1m2

What’s the price per square meter?

Decktec offers many advantages for under $16/m2

What’s the price per lineal meter?

On average Decktec will cost $7.32 / lm

What’s included in your Decktec Decking System?

With every Carton or 6-Pack, you receive adhesive joining pads, fixing clouts and instructions.

Is it normal for the Deck strips to buckle?

With temperature variations throughout the day the Deck strips may rise between fixings as it gets warmer and settle again as it cools. This will not affect the function of the Deck strips as boards are laid. Testing has shown Decktec’s Deck strips will move 1mm over a lineal metre with every 10 degrees of change in temperature.

Can you lay out the entire deck prior to fixing off boards?

Yes! One of the many advantages of Decktec is the ability to position all the decking boards before fixing them off! In the case of an extremely twisted board, a fixing here or there may be required to hold the board. Once all positioned, flick a chalk line through the unique stand-up spaces, then simply fix off with perfect screw lines! Decktec recommends using talc powder for the chalk line to avoid staining the timbers.

Do you need to fix the joins progressively?

Although not necessary, prior to fixing down the deck, Decktec recommends fixing the joins first to keep them tight.
