ben2008 Posted November 10, 2020 Report Share Posted November 10, 2020 (edited) I'm sure this has been discussed many times on here, but here goes anyway. After you finish a fretwork and want to apply a black backer board how do you go about applying it? I have a small scroll saw project I'm working on . A "Butterfly clock" that I want to apply a small black background to it. I have some 1/8" plywood that I will spray paint one side black, then cut to size. What should I use to apply it? Thanks in advance Ben Edited November 10, 2020 by ben2008 OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
jollyred Posted November 10, 2020 Report Share Posted November 10, 2020 I generally use Aileen's clear tacky glue. Just put small drops in the area I want the glue, then spread it around with my finger. I do try to keep it away from the edges of the frets, and keep the glue thin. Once the overlay is in position, I will use a pin nailer to secure it from the back, if the wood is thick enough to keep the nails from going all the way through. Otherwise, I don't bother with the pin nails. The nails are just in case the glue should fail, so I only use a few around the edges. I have some 3/8" pin nails, so most of my projects are 1/2" finished thickness. Pin nails are also good for reinforcing butt and miter joints in thin material.

Denny Knappen Posted November 10, 2020 Report Share Posted November 10, 2020 I use Titebond 11, but then I stain the backer with water soluble stain. ben2008 and OCtoolguy 1 1 Quote Link to comment Share on other sites More sharing options...
dgman Posted November 10, 2020 Report Share Posted November 10, 2020 I too use Aileen’s Tacky glue. If the area is wide enough, I apply it with the bottle tip, otherwise, I apply it with a toothpick. I apply it thin enough to not get any squeeze out. If I do get squeeze out, I clean it up with the other end of the toothpick. As far as painting the backer board, I use flat black spray for two reasons. Flat paint cures faster. You want the paint cured before you glue it. Second, I apply my top coat after the backer is installed. That way you are not putting a finish on top of a shiny paint.

munzieb Posted November 10, 2020 Report Share Posted November 10, 2020 I use Spray contact cement to attach to backer and use CA glue along the edges to hold it down. The material is a 1/8" pattern and a 1/4" luan backer. I use a black acrylic paint that dries very quickly. I did a YouTube video a while back and the latter half address what you are asking about. https://www.youtube.com/watch?v=G2Zpr7AY7og&t=274s jollyred, OCtoolguy and ben2008 3 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted November 10, 2020 Report Share Posted November 10, 2020 Not sure if you was asking what type of glue or how to apply.. I won't go into glue types as everyone will have their favorite glue, car, boat etc... I use a plastic garbage sack.. but you can use wax paper etc.. Lay the bag / paper out on the workbench.. pour a appropriate amount of your favorite glue and I use a plastic body filler spreader to spread the glue out as evenly as you can.. Dip the back side ( this is important.. make sure you dip the right side you want to glue, I've messed this up more than once and dipped the front side ) into the glue and press it down so it gets glue on it good.. lift it up and stick it onto the backer.. Clamp or put weight on it however works best for your situation. Put the bag out somewhere so it can dry and you can peel off the glue or shake the bag and most the glue will peel off, then you can still use he bag for its normal purpose, lol GrampaJim, munzieb and ben2008 1 1 1 Quote Link to comment Share on other sites More sharing options...
teachnlearn Posted November 10, 2020 Report Share Posted November 10, 2020 Saw a youtube the other day. Wasn't scroll saw, but noted his glue technique. He put strips of glue spaced, then put CA glue 'crazy glue' in the spaces. He held it in place enough for the CA to grab. CA glue can be used as a two part, so the glue in applied to one piece and the instant set is applied to the other piece. It eliminates the pin nailer, clamping, or putting weights on the project. Filed this technique away in my brain to use if I'm short on clamps or a pin nailer isn't available. One additional missed 'clamping' technique is taping a few places. Little off track from glue. I'm covering some of the responses that could or couldn't be used from lack of equipment or space. RJF kmmcrafts and munzieb 1 1 Quote Link to comment Share on other sites More sharing options...
teachnlearn Posted November 10, 2020 Report Share Posted November 10, 2020 Couldn't edit my post; the instant glue technique could be used on a production basis. RJF munzieb and kmmcrafts 2 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted November 10, 2020 Report Share Posted November 10, 2020 I should have posted a link to the body filler spreaders.. I use these to spread the glue out evenly on the wax paper or plastic trash bag.. one spread out you just set the piece to be glued to the backer into the glue and then put it on the backer.. https://www.harborfreight.com/4-in-putty-spreaders-20-pc-69564.html munzieb 1 Quote Link to comment Share on other sites More sharing options...

Ctutor Posted November 11, 2020 Report Share Posted November 11, 2020 I use Titebond clear. It goes on white but dries perfectly clear Any minor spillover that I do not catch is no problem because the backer board color shows through munzieb, OCtoolguy and ben2008 2 1 Quote Link to comment Share on other sites More sharing options...
NC Scroller Posted November 11, 2020 Report Share Posted November 11, 2020 I use Weldbond glue. It is white and dries clear. It works with painted and stained backers. I apply the glue with a small paint roller I covered with foam pipe insulation. The glue goes on the back of the piece you are attaching the backer to. munzieb, OCtoolguy and ben2008 2 1 Quote Link to comment Share on other sites More sharing options...
WayneMahler Posted November 12, 2020 Report Share Posted November 12, 2020 I use Titebond 2. Just enough glue on the back of the art work to hold it. If I get any sqeeze out I clean it up with a piece of paper towel and a toothpick. Works great for me. ben2008 1 Quote Link to comment Share on other sites More sharing options...
ben2008 Posted November 12, 2020 Author Report Share Posted November 12, 2020 Thanks everyone for the comments and tips. There are some I'm going to try, then I'll pick which one works best for me. Very much appreciated. Ben Quote Link to comment Share on other sites More sharing options...
crupiea Posted November 12, 2020 Report Share Posted November 12, 2020 When i think the glue will ooze out and bee seen i brush on clear tacky glue. I put the glue onto the fretwork side. Takes a while but its nit as bad as you think once you get going. If it not in an are that oozes out I just use wood glue. I always use a paint brush to apply it either way. Doesnt take as much as you think. ben2008 1 Quote Link to comment Share on other sites More sharing options...
tomsteve Posted November 13, 2020 Report Share Posted November 13, 2020 ive been using bob smith medium ca for years for backers. run a bead around the perimeter on the back of the fretwork, dabs here and there and on fragile parts. set it on the backer. put a piece of ply over it and some weight. done in 2 minutes. if any squeezeout, it dries clear kmmcrafts, munzieb and ben2008 2 1 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted November 13, 2020 Report Share Posted November 13, 2020 I often wonder how chemical resistant the different glues are.. I glue to unfinished wood.. wait 12 -24 hours for glue to dry.. then I soak in Danish oil for about 10 minutes.. pull out and set another 10 min. then wipe off and let dry.. I've not had any issues with the chemicals loosening the glue bond... but it's something I constantly worry about.. I use the Tite-bond translucent glue.. always have and always will mainly because I haven't encountered any issues with it... afraid to try anything else.. because of this method and worries of a disaster, LOL Any thoughts on the chemicals and the glue? ben2008 1 Quote Link to comment Share on other sites More sharing options...

With Aileen’s Tacky glue I can have my project in oil 15 minutes after gluing. Been doing this for 20 years without failure. kmmcrafts, ben2008 and danny 1 2 Quote Link to comment Share on other sites More sharing options...

Yes, it does dry clear, however, I still clean up any squeeze out as it will inhibit oil absorption. ben2008 and kmmcrafts 1 1 Quote Link to comment Share on other sites More sharing options...
Foxfold Posted November 13, 2020 Report Share Posted November 13, 2020 I just use a pva glue because Tony has lots of it. Put it onto my fretwork and the put on the backer, clamp and wait. Not 'professional' no doubt but it works for me munzieb and John B 2 Quote Link to comment Share on other sites More sharing options...
