I'm about to embark on covering my lounge floor to eliminate the
undulating carpet effect.

I'm going for 3mm hardboard as recommended by my trusty Collins DIY
manual, and was thinking of using a nail gun to make the job a bit
easier.

I'm looking at the light duty brad nailer in HSS. Would this be
sufficent, or would I need something a bit more heavy duty?

Anything else I need to be aware of before I start?

Lay the hardboard at 45 degrees to the floorboards to avoid all undulations
being parallel to the walls - seems to 'feel' better.
