Sanding primer ?

[mikeallan257]

I have one quick? question about primer. Without getting into specifics, when you sand your primer, should it sand off down to the wood easily? I used 3 coats of primer, I sanded it down lightly and it went to the bare wood rather easily in alot of areas. Oh, it dried for 4 days before I did any sanding also. My question would be is this normal and do I just keep primering until I achieve full coverage or is this a bad brand of primer?

Thanks for your advice,

Mike.

Mike - I dont even sand my primer. ( unless I have a run ) I use water based paints and never had a problem.

What grit paper are you sanding the primer with? The primer will sand off quite easily. Just give it a light sanding. Just enough to smooth it out.

Great looking lure!

I used 220 grit. Perhaps the primer didn't bond to the sealer? I used the envirotex method of warming the lure in the oven and sealing with envirotex.

Here are a couple of sample photos. I sanded because I had read in other posts that you may not have good adhesion with the paint if you don't.

It appears to just be over-sanded, as stated above, you really only need to scuff the primer, to level the surface and make it rough enough for good paint adhesion. A light scuff with 320 is usually enough, and use less pressure near any edges, or you'll be right thru the primer and down to the wood.

Scotchbrite green lightly in two directions. If you have a drip or sag then use sand paper or drag a razor blade (sharp edge trailing or vertical) across it to scrape off the lump.

 

Works well for me using BIN red label primer.

i would give the sealer a lite sanding scuff it up also not so much pressure sanding the primer-take it easy- good luck
