Theres got to be an easier way!

9mm twice isnt as strong as 18mm though and even ring shank nail can still pull out? I only ever screw it down

Its not often I use ply anymore, I've been converted to hardi boards. Thing with the nails is you can put about 4 times the amount in a board,in half the time. With addy, grout and tile weight its very secure, and dare I say it, more secure than screwing?

mmm... each to there own I think, I've never really got on with nails over the years, and only use them for things like wooden beading. Screws 'pull' the ply down to the floor and hold it there.

I know what you mean though, its time consuming screwing all those screws in.

On the subject of drills my Makita LXT 18V 3.0ah (11 months old) has just got the flashing lights of doom on one battery from the charger to suggest its had it. These batteries are damn expensive and I've heard loads of tales about them failing just after the guarantee has run out.

In fact its a year old in a weeks time.

screws have a weakness between where the thread finishes and the head starts. next time you shear a screw look at how small the section is, for a long time we had to use ring shank as screws were considered too weak, ringshanks wont hold chipboard flooring down so the chipboard screw was developed and is the only screw that should be used to hold chipboard floors down, with ply screws are not so good as they seperate the laminates while srewing in, the best way to fix ply down is with ringshanks as the downward force breaks the laminate downwards as it drives through forcing the downward facing laminate into the rings preventing the nail from pulling up again

having just read bobs post I remember that if you are overboarding over chipboard use chipboard screws if you are overboarding over ply or timber use ringshank

When I was taught about ply lining I was told to always drill a pilot hole if screwing down to stop the screw pulling the layers apart and leaving a void between floor and ply. Making a tedious job twice as long. Hence staples if I do ever ply line

Turbo gold scews (screwfix)

I use one of these with a compressor



It fires up to 50mm lg. ring shank nails at a rate of up to 3 nails per second so you can put a lot of nails in quickly. I usually use it to prep for vinyl tile 6mm ply with 22mm nails or 9.5mm with 27mm nails. You can set the depth as well. I have it so it just breaks the surface of the ply and no more.

BS5385 recommends screws..

If ring shanks wont hold down chipboard they wont down ply either, nails pull out screws dont.

Simples


Each to their own i guess but ill continue to screw down my ply

Always use screws...... Usually a 40 - 50 mm 5.0. Have ripped up many plyed floors in he past, and when I have to do it, I hope it's been nailed, as it's much easier to remove than a screwed one.......

NEVER underestimate the power of wood!
Fluctuation in temperatures and humidity will bend wood and I have seen a limestone tiled floor section lifting. When walked on, it was flexing considerably.
The nails were over 100mm long. I was asked to repair somebody else's work... the weight of the limestone and fixing material was quite considerable but it didn't help keeping it down.

Think about it... wood was used by the Romans in quarries to split sections of marble blocks.

I have one of these:

Quik Drive® Auto-Feed Screw Driving Systems

It is truly amazing, screws are expensive but the time saving is unreal. There is a clip on there racing a guy with a DeWalt impact driver, its no contest.

now that is what I would call a really useful tool
