Sealing Maple: Techniques
 
This is my second season building plugs and I just completed a series of Maple Donnies. I am about to move onto sealing them. After some research online and getting input from a couple other plug builders; I am going to be moving forward with epoxy sealing these plugs. I have never epoxy sealed a plug before, so I was hoping to get some input from builders here. Based on the research that I have done here, I am planning on moving forward with the following technique.

The following seems to be pretty standard:
- I plan on using Etex
- I plan on heating the plugs in small batches in a small oven for 20 minutes at 180 (or so) degrees prior to epoxy sealing.
- While the plugs are heating, I will mix up a small batch of epoxy; trying to time it out with the plug warming process.
- I plan on either pouring the etex down the through hole of the plug and catching it in a cup at the bottom. Another option is using a syringe to shoot the epoxy through.
- I will also brush the exposed wood grain with the epoxy.
- It’s a somewhat messy process the first few attempts.


I guess I am asking for clarification or tips/pointers on a couple items:
- Thinning the epoxy (Yes or No). If yes, how do you thin and with what material?
- Do you just epoxy the exposed wood grain (end grain, hook holes, lip slot, etc) or do you brush the epoxy over the entire plug and let it soak in? I hear differing opinions about this topic.
- If you brush the entire plug with epoxy; what will the plug look like when you’re completed. Will it have a shine to it? What’s the best way to know that you’re done?
- What sort of brush do you use to apply the epoxy? Foam, bristle, etc…? Does it make a difference really?
- How long do you let the epoxy coat dry before applying a primer coat?

I know that I am missing some steps, so any advice would be appreciated.

System three clear coat would be a better choice for sealing than Etex , that stuff is pretty thick.
Personally I would not mess with thinning it as it would be highly toxic fumes from the thinner needed.

BTW to be really waterproof you need three coats of epoxy sand or scuff between.

I use system 3 for over coating the painted plugs, 2 coats. Plan to use it for one of your maple plugs Kev. No thinning. Heat wood yes. Messy yes.

I was told to thin with denatured alcohol. Also was told not to thin at all. What I was told was to pour epoxy over the plug into another cup. So you're just pouring from cup to cup.brush off extra then wipe. Also to make your epoxy flow better is to warm the bottles in a hot water bath. It will be runny.

I see epoxy sealing as a viable step for sealing maple. I don't see it as a sealing method for doing large quantities of lures. It has to be extremely time consuming and messy. Being that end grain is where water would intrude, I would think pouring down thru wire hole, hook hole, eye cutouts and lip slot would suffice.

True Billy but isn't there exposed end grain when you taper a plug? But I agree ends if plugs hook holes and slots

I epoxy seal all my maple/birch this way.

Heated in toaster oven, 200 degrees for 15-20 minutes

I use etex and denatured alcohol to seal.

I heat my epoxy bottles up in hot tap water, helps thin it out a tad

I mix the etex like you would for topcoat.

Then I cut it with the DA about 25%, at first it won’t want to mix, but keep stirring and it will mix just fine

I remove the warm plug and pour the epoxy thru the plug, making sure it runs out of both ends, hook and eye holes, ill pour it thru the tail first and then flip it and pour it thru the nose, hook and eye holes, basically making sure the whole plug has had the epoxy poured thru it

I use cheap plastic cups, I’ll put maybe 1/4” of epoxy mix in the bottom of one cup and after 1 plug is done I just let it sit nose down to soak up more and then flip it when the next plug is done

I’ll do 3-4 plugs at a time and then wipe them down with lint less paper towels, like the brown kraft towels

If the plug has a lip slot I make sure to hang the plug tail down, so any excess epoxy doesn’t cure in the slot.

One you’re all done doing all your plugs, double check the bottom end for excess and wipe if necessary

Allow to dry 24 hours minimum

The results are a rock hard sealed plug, works great for softer woods too, helps make em less soft

Chris so u don't do the outside of plug, just the end grain?

Yes I do the whole plug, inside and out, not sure how I forgot to include I do the outside of the plug, guess that’s what I get for typing on break :)

Has anyone tried sealing with this first?

Interesting for sure.

Never tried it

Looked into that product. Sounds like it what we could use. Pricey compared to e tex but about the same as Sys. 3

Thank you to everyone who has replied so far. I'm going to be drilling the maple bodies this weekend and will make an attempt to Epoxy seal them. I'm going to start with 1 and see how it goes.

What do production plug makers use for birch/maple if they don't use epoxy? Also which system 3 epoxies is anyone using for sealing or top coating?

It would seem that you would have to through wire before sealing as the holes for through wiring and tail weights would get clogged or reduced to the point where the wire would not go through or the weight would not go in if you sealed first. So far I have been sealing with 50/50 spar urethane/mineral spirits with medium success, and etex for top coating.

Minwax wood hardiner worked awesome. I think that they stopped making it.

I have seen the minwax wood hardener in stores still, it just may be more difficult to find as the paint regulations for all the nasty stuff puts limits on what can be sold to retail. I have some and use it on maple and even on AYC sometimes. I like to use it for red cedar that I use on pencil poppers.

No the holes all stay clean with epoxy sealing, that’s one reason you cut it, it soaks in and doesn’t clog the holes for the wire or swivels

System. 3 clear coat Fred. Epoxy soaks in fast in a warm microwaved or oven heated plug. No need for thinning this product IMO. It is very thin to begin with. I use a pipe cleaner thru the thru hole and wipe off any excess epoxy with a paper towel after a few minutes. Just a messy process so have everything ready to go. Fumes on a warm plug are not very nice for several minutes after application so an exhaust fan is a plus. Personally I have not had any issues sealing birch with the spar concoction as I prefer birch over maple and use that for a few of my darters or AYC.

Hi Paul,

I still have to get together with you and get a couple of carbide bits, if you still have them.

I havent made much in hardwood to date, mostly needles. My issues have been that sealing reduces the diameter of the through holes and weight holes and i have to redrill, not that i have had much cracking. Maybe I will have to get some pipe cleaners. What are the advantages of system 3 over etex?

ProfessorM 12-16-2017 01:13 PM

I have plenty of inserts. I put my belly wgt’s in before sealing if your talking tail wgt hole make them bigger by a 64 and it should not be an issue

fishing bum wannabe 12-16-2017 01:55 PM

I had been putting my tail weights in after sealing. I make my own and unfortunately, even drilling over size they all don't fit. I am using wood molds which after a couple of pours are not teribally accurate in size. I hadn't thought about putting them in before sealing. I missed a nice looking tail mold on SOL earlier in the week that might have solved the issue of inconsistant diameter.

ProfessorM 12-16-2017 05:15 PM

I put the belly wgt’s in I do not put the tail wgt’s in before sealing but I would imagine if you sealed the plug and before it sets you then slide the tail wgt in that would solve the issue. I would imagine the issue is after it hardens up so sliding in while the epoxy is still damp would solve your dilemma

Fred, It might be worth it to buy a blank do-it mold and drill it out yourself for the tail weights, that is what I did and it works well.

Thanks Bruce. I have been debating doing that for a while anyway. I've had enough practice doing wood ones so drilling should be pretty straight forward. On the one that sold on SOL there was a fixture attached to the top of the mold that would keep the wires for the through hole centered. That looked very interesting. I might try that as well. I wish I had Paul's experience and access to a machine shop but I think I can muddle through on this one OK.
