Spraygun

[gdf26562]

I recently finished lacquering a 1.5 x 1.5mt dining table, using Stylewood lacquer. Using a air compressor and spray gun, for some reason, which I can't fathom, on finishing in the light you could see the lines where I sprayed.

Obviously not a good look, I am unsure as to what I was doing wrong, one problem was actually spraying a large surface, and trying to get an even finish.....

I noticed when spraying that the spray left a thin film on the area that I had previously coated, My question is, how does one spray a large area without leaving lines, is there a trick with the lacquer, do I need a real low pressure. I have reead a little on it but can't seem to find an answer, any help would be appreciatted.

It sounds like you needed more thinners in the final coat.
Or did you spray it outside in hot sun.
Rub it back with some wet and dry and give it another coat. Being a table top you could lay a nice wet coat on without fear of runs.

You need to determine what specificaly is showing up as lines.

a couple of causes

insufficient build

material insufficiently thinned.


or most probable
overspray fron the later passes settling on previous passes that have partly gone off.

retarding thinners can be helpfull slows the drying & allows following coats to settle into prevoius. allows the coat to self level (a bit).

you may need to rub out final coat any way?

If you are spraying anywhere warm & dry retarding thinner is almost mandatory.

Thanks for the replies, thinking back on it I did not thin the lacquers which probably caused the lines, and the overdying, hopefully won't happen again.
