Title: Speaker Paint
Post by: John M. Roll on January 07, 2022, 06:24:10 PM
There are a few speaker coatings out there. Duratex comes to mind, but it's expensive. Is there a less expensive alternative or is this a "buy once, cry once" scenario?

For the cabinet(s) right?

Sherwin-Williams Polane-T.  I think it's available in as little as 1 gallon quantities.

Duratex and Exohyde are basically the same product in my book.  I've used both.  For the DIY'er, these are your go to products.  Coat cabinet edges and corners with a second coat for a bit more protection.  That said, Duratex is about 20% more expensive:  Currently $70/gal vs $82/gal.

Real truck bed coating such as LineX is really the way to go, it is tougher and thicker.  It will be more expensive, but IMO, worth it.

Best regards,

John

Duratex works out to about $10 per cabinet based on my experience, with the ability to touch up when needed. Its not that expensive in the grand scheme of things, and it has lasted 5 years on the floor monitors I built, with just ordinary wear and tear from weekly use. I agree Line-X or Rhino is the ultimate in pro audio speaker finish but takes a pro to apply it and Id assume it is probably 4x as expensive as a DIY Duratex job. I have wondered how the DIY truck bed liner that you can find at automotive supply houses (Herculiner, etc.) would hold up. Found this article about a guy who re-did an old bass cabinet with Herculiner a few years ago. https://www.talkbass.com/threads/herculiner-coating-on-my-speaker-cabinet.1341793/

Used Duratex for years for installed speakers, but not really pleased with durabilty for road-use. Last year started using ExoHyde, with somewhat better results, but still not as durable as I would prefer. ExoHyde seems to adhere to bare wood better. Right now Exohyde is back-ordered until mid-February, so I may have to look at using Duratex or a new product for a small order I am starting on.

It's best to sand the cabinet with nothing finer than 60 grit, and make sure it's dry and blown off of dust. 

Adhesion to old finishes will vary, but I've had decent results with rough sanding old commercial texture paints/lacquers used in the industry with the 60 grit, dusting off, and wiping down with a bit of alcohol or other spirits to degrease.

This is also a recommended procedure if taking the cabinets to a LineX shop for spraying.

Best regards,

John

from recollection... duratex outgasses water when curing.  rhino and other outgas vapors including cyanide... so depending on where you'll be finishing and curing that might be important... multiple costs of dura tex is what I prefer

A lot of larger shops go the Polane route in the off season.

A set of X-Array hangs outdoors here all season.  Between the depth offset into the cab and a robust grill water never is an issue.   Take em back to the shop, run the sweeps, paint and wait until next season.  Of course theyre not getting banged around in a truck.

As John mentioned, surface prep, surface prep, surface prep, no matter what product you decide to use.

We've had good luck with duratex but horrible experience with exohyde. We were hopeful the exohyde would perform as well as the duratex, but after fully curing, we had areas all over several cabinets that looked like the material had shrunk, causing it to crack and show the bare wood underneath. We sanded a few spots down to make sure there wasn't any filler beneath and it was only wood. Luckily we only opened one tub of it so we sent the rest back for PE and ordered more duratex to replace it. It's kind of a shame because the exohyde went on way easier than the duratex, but I guess the tradeoff was a wildly inconsistent surface finish that made it unsuitable for use.

I've done truck bed products like Line-X, Herculiner, Duratex and good old oil based paints.  The professional truck bed coating are super tough, but not a substitute for proper feet/skids and once you break through, a refinish is a real problem.  Herculiner turns white and chalky from UV exposure, so be warned if you do lots of outdoor work.  It's pretty rough on the hands too.  Oil based paint doesn't cover blemishes and doesn't have texture but it's actually pretty tough.  It takes forever to dry though.  Duratex is my preference these days.  No it's not indestructible or even close to a pro polyurea coating, but it's so damn easy to apply with no bad smells, I just re- apply as needed, which isn't that often.

I just bought a gallon from Parts Express.  Grabbed some spare rollers plus XLR's to get to $99 for free freight.
