Hard wood installation problem.?

Question

I was watching a friend of mine, who was doing hard wood installation for the first time, he used Hydrolic nailer with a noisy compressor, for each plank he was nailing 3 special nails into the groove of the plank, BUT when trying to insert the next raw, we noticed small gaps, even if you hit them with the hammer the gap want go away, the cause was that the nails inside the groove in first row where not fully flushed with the surface, by using a big nail and hammer we manually pushed those nails inside the groove, after that the gap disapeared and with little effort the second plank was fitting perfectly.
So where did we do the mistake, why the nailer didnt insert the nail deep enough??
Thanks for answers.

Answer 1

There is a depth adjustment on the air nailer. Hard to tell you where to look without knowing which model or even a brand of the gun but most have an adjustment. Usually takes a hex key or torx key to make the adjustment.

Also, if the compressor is not producing enough air volume, the hose is too small or there is a leak in the air system you can have the same problem.

Answer 2

There should be a setting on the nailer for how deep to set the nails in. Once you get the depth set right you should be fine. Also make sure you are putting in the nail at the correct angle.

Answer 3

Read the directions with the nail gun. The nails need to be set deeper. Find the adjustment on the gun and turn it up a little until the nails are flush. Once you get it set right, then it will make the job go easier. good luck.

Answer 4

Was he really nailing into the groove???? If so, that's the problem. The nailing should be on the top inner edge of the tongue, not in the groove.

Answer 5

You probably just needed to set your nail gun to a higher pressure.
