Ljk Posted February 20, 2018 Share Posted February 20, 2018 I have a plywood horn that needs paint/coating, I would like a strong durable long lasting finish for inside of horn. Is duratex my best option or maybe some type of expoxy paint. Thanks! Quote Link to comment Share on other sites More sharing options...
pzannucci Posted February 21, 2018 Share Posted February 21, 2018 Either or. Depends how much work you want to put into it and what your resulting finish requirements are. If you want a smooth finish, go with the epoxy though may take a few coats. Rough one coat, duratex. Quote Link to comment Share on other sites More sharing options...

Just use a smooth roller when applying it instead of the texture roller they supply. Quote Link to comment Share on other sites More sharing options...

Thanks! Smooth finish is what I'm looking for so I will look into epoxy. I don't mind the extra work. Cecaa850 - We must been typing at the same, which coating would last longer and be easiest to work with? Might come down to cost.. Quote Link to comment Share on other sites More sharing options...

The key on both of these will be the base coat. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted February 21, 2018 Share Posted February 21, 2018 Duratex is really thick. It won't make a glossy finish but will lay pretty flat with a short roller. You can use a paint brush with it as well. Quote Link to comment Share on other sites More sharing options...
Ljk Posted February 21, 2018 Author Share Posted February 21, 2018 Was looking at home depot online and found a spray epoxy appliance paint. It's cheap only 3.79 for a can, I going to pick a can today and give a test run on a piece of scrap plywood. I will let guys know it works.

HPower Posted February 21, 2018 Share Posted February 21, 2018 With the use of some crumpled up cellophane or plastic, you can get a leather look to the finish. http://techtalk.parts-express.com/forum/tech-talk-forum/27527-durotex-leather-look I was going to try this technique when I built my F-20 sub but got scared by the size of the cabinet so I ended up using their textured roller for the "normal" look. I did test the leather technique on a small piece of scrap, and it did give a real leatherette look. Quote Link to comment Share on other sites More sharing options...

Might work for outside cabinet will keep it in mind. Picked up a can of appliance paint yesterday and it seems to work well. Did 3 light coats on a piece of plywood and so far seems durable. Took a screw drive and tapped the paint with no chipping. Scratched it with the screw and it did leave a mark but I,don't think paint was completely dry. Decided to try it on the inside of horn, maybe a few days but I post my findings. Quote Link to comment Share on other sites More sharing options...
moray james Posted February 22, 2018 Share Posted February 22, 2018 use a sealer/primer first after your surface prep.The sealer will stop paint from sucking into the wood. Remember the prep time that you spend will determine the ultimate quality of your finish. Pick a nice color for the inside. Quote Link to comment Share on other sites More sharing options...

Was not going to use a sealer but did not think about the paint sucking into the wood, good point! I am just going with black since there will be grill on the front of speaker. Sand, sand, sand till I am sick of it then sand once more, got to be the worst but most important part. Good points moray, thanks. Going to get back to it on sunday.

It is best to use a wood that will not be so rough after the first coat (raises from absorbing the paint) thus to minimize sanding. I do love sanding - NOT!!!

Using a pine plywood, had do a little Bondo work so I am just using .99 cent flat black from home depot to find the bad area's. (More sanding, yea!) Since I had to do a little Bondo work I am going to use some filler paint before spray the epoxy. As usual this project is getting more complicated the expected.

Does it dry to hard finish the like the do it yourself truck liners? If I used it after Bondo would it work as a sealer/filler? Wish I could look/buy it a brick and mortar store.

DizRotus Posted February 25, 2018 Share Posted February 25, 2018 It dries to a very durable finish. I spoke with the people at Duratex regarding covering Bondo. They said it can go directly over Bondo without primer/sealer. Quote Link to comment Share on other sites More sharing options...
