Dipping Primer/undercoat

Recommended Posts

Hello guys, I am looking at moving to dipping my larger wood lures .Have till now sprayed or brushed a white undercoat/primer over sealed lure but for grainy wood I feel dipping might be quicker smoother.i am considering zinsser bin , possibly thinned , advice appreciated.

The fact that you mentioned 'grainy wood' makes me think that there is something wrong with your sealing procedure. All thoughts of wood grain should be gone by the time you come to apply undercoat.

 

The seal coat is not just about stopping water getting into the wood, it is more about fixing the grain, to stop it rising when you add a wet coat of paint. The seal coat will cause the grain to rise. You then sand it smooth. While sanding, you may have pierced some of the seal coat, so you have to apply another seal coat. Keep repeating until the grain stops rising and is fixed. Now the base coat should go on real smooth.

Cheers dave, I seal with thinned epoxy, however with light meranti no matter how much you sand you still have open grainy finsh to wood.I have until now added another coat off epoxy to get smooth, but this is very time consuming and a waste of epoxy.even with 1 un-thinned coat of e-tex on meranti you still get grainy finish, by grainy I dont mean raised grain, I mean the pores are not filled.

OK, nothing wrong with your method, just a difficult wood. What I would do with this, is pre-seal with CA glue first. Again sanding and re-applying. Because CA glue sets very quickly, not much time will be lost. This should ensure that one coat of thinned epoxy will be enough to complete the seal with a smooth surface result.

 

The other alternative is a skim coat of car filler to fill the troughs in between the grain. This stuff sands real easy and goes off quick too.

Cheers dave, it is a tricky but v. good wood.have often used c.a . In past still do occasionally on proto types, but I'm making more and more larger ones .I get good results with 2 coats white primer and sand, this fills and smooths any remaining grain pores.I am specifically asking will dipping be as, less, or more effective and if so how highly rated bin is for this? Cheers again.

you will have no problem dipping. rotate the bait or put it on a wheel/turner. dry time will be longer due to more primer on it. or try lacquer primer. dry times quicker. it bites into your epoxy coat for adhesion. we do this on cedar crank bodies

lacquer base is  solvent based. zinnser products are alchol or water based or shellac based. all the mentioned will work well,if you pre-sealed with epoxies like enviro-tex or new lustre 55 . . zinnser products alone without pre0seal epoxys will chek/crack on woods,especially cedars and softwoods. in climates with larege temperature changes even more so. we build musky lures here and do re-paints for clients and do production painting for other companies. with woods metals plastics foams theres differences in evey one for best results. seeing your building gliders I surmise your making musky lures?

I use e-tex to seal,mostly gliders, meranti and cedar, for pike.I am looking to streamline the process , hence the dipping.looking for strong ,dippable ,white reasonably quick drying primer that will even out small dimpples left in meranti after 1 coat e-tex sealer and be smooth enough with little sanding ready for painting.advice much appreciated.
