I hired a Powernailer P50 to do my floors with, and I've been practicing on it with some spare flooring and a piece of ply. I've got it adjusted correctly to the height of my flooring, and the psi is right on the money of what the manufacturer recommends. I'm finding though that I'm getting a bit of splitting - do I have to adjust the psi, or is it just the nature of the solid hardwood and the fact it's only 1/2" thick (with a matching thinner tongue) that's causing the issue?

Any ideas or suggestions?

AA,

Make sure to use the recommended 18 Gauge cleats (these are thinner to reduce splitting) and back of on the pressure, if 70-80 psi seats the cleat that is all you need.

typicaly you'll get alot of splitting sometimes. As long as the cleat or staple is going into the body of the wood floor through the tounge you should be fine. Make sure you use 30 or 15lb roofing felt under the wood. It helps with the staples or cleats bond better, plus it's a semi moisture barrier and sound proofing
