Stapling fit from below spreader plates

[blankton]

This might seem a stupid question, but has anyone got any practical knowledge of stapling these up? 

 

I've got them fitted, but before I add insulatuon and seal the gap with plasterboard I want to get plenty of staples in, as currently there are only a few and there are some detectable air gaps. I've read the importance of many staples. 

 

The issue I have is that I'm really struggling to get staples in. The floor upstairs is a standard 22mm chipboard flooring, as used on new floors these days, it just seems too hard for the staples. 

 

I've tried two standard staple guns. One an old school manual gun and a tacwise electric stapler. These are both firing a medium thickness (18ga) staple. However, they just crumple up. The staples are 10.5mm across the crown, with an 8mm leg length. 

 

Thicker gauge staples are made in 15 or 16ga, but they seem to have either very long legs (25mm) or have an unusual shape, such as a curved crown. I would need to get a pnulatic stapler as well. I'm not against getting a pneumatic stapler, but I can't see any that fire a standard looking staple, but in heavy gauge wire (which is what I think I need). I've spent hours looking at staples. 

 

Aside from staples, the best solution I've found so far are 13mm clout nails (like you'd use on your shed roof), but this is very time consuming. 

 

Does anyone have any advice?

On a recent project I just used 1" 8's with small washers and a very long bit holder in the impact, as access was a bit tricky.

 

I've posted on here about stapling up from the underside, again into 22mm P5 Egger, and I did that with an air-powered stapler, and 10mm staples, which worked a charm. More the merrier, and the air stapler made it a quick and easy task.

Thanks. Do you have a link to the staples? I am trying to work out the gauge. 

 

If I can get a stapling system that works, it will save a lot of time. But otherwise I'll have to try screws and washers or clout nails.

It was a cheap B&Q DIY compressor set that I bought to do these types of jobs, and a lot kore to be fair, and came with the stapler.

 

If the job isn’t huge then I’d persevere with screws and washers. Clout nails would be my very last option.
