Yes

We recommend the use of Sika flex 11fc for the following reasons:
1.      It is like putting your foot into a sock before you put into a shoe - it just feels better
2.      Adhesive adds a cushioning when walked on
3.      Adhesive takes the ‘clickety clack’ sound out of the completed deck when walked on
4.      It also adds a massive strength boost making it suitable for cyclonic areas up to category 2 strength. 

5mm or 3/16” consistent (USA)

No ,you just need standard square edged boards

Any sized merbeau board

Yes, the top of the weather closing on the clip finishes 4mm lower than the top of the deck allowing sanding and polishing.

No, check your joins at the end of the job and check for any discrepancies which may need adjustment.

The outside board is the anchor, it must be straight and well held. Please refer to video for demonstration.

14 per square meter if using 140mm boards or 22 deck claws for 90mm wide boards.  It is far more cost efficient in labor and deck claws to use the 140mm wise board. 

Please refer to the video for instructions.

With a small flat screw driver flick back the clip weathering closure and expose the two screw heads. With a slow speed battery drill fitted with a T10 driver bit slowly unwind the screws to as many clips as you need to remove the damaged board. Again with the small flat screw driver and hammer tap and flick the stainless steel deck claws out of their engaged position, then with a long blade adjustable cutting knife cut down between the nylon spacer and the edge of the board you are taking out, this will cut through the deck tape. We recommend you put on top of your joists before you install your boards, the bond that the joist tape has to the top of the joist will release as you work your way along with a pinch bar, simply cut small lengths of fresh joist tape to replace the tape you have removed. Install new deck claws , apply fresh sika 11fc and refit a new board, and finally engage the deck claw screws and weathering closure.
