Has anyone used this? Wonder if it's up to the contract flooring side of things or if it's just suitable for domestic
No, but I personally think it's the hardness of the nails that needs looking at. Concrete nailers are usually pretty good but usually get let down by the nails as they can bend in certain concrete floors. I doubt it'll go into powerfloat as said the nails will bend before you can give a true test on the nailer itself. This one is at a reasonable price. https://www.tradediscountshop.co.uk/shop/tds-concrete-pinner-2564/
