Depends on the temp and humidity of the room the cab is in. Duratex dries dry to the touch in a few hours, but it's not fully CURED until about the 7-day mark. The "full cure time" is significantly reduced if you can put the cabs outside in the sun on a 80+ degree day or if you can make "a hot booth" with plastic sheets and electric heaters.


That's the long and proper answer. The short answer is this: If you don't care if you smudge/damage the duratex hidden by the mounting surfaces of the drivers, wait 48 hours and install them.

I have read somewhere, probably on Acryltec's website what the optimum curing conditions are for Duratex. What I know for sure is that the stuff likes heat. I've used the stuff for the past 8 years or so and have lots of experience with it. At least the rolled-on kind. Never used the spray stuff yet.


After a few hours it feels dry to the touch and you can roll on another coat. But if you try to pickup the cab the Duratex will come off on your hands. It doesn't so much "dry" as it does "cure."


The BEST advice is to just let it dry for at least 7 days, assuming you're the average DIYer and are Duratexing cabs in your garage/back patio/kitchen when the wife's not home. But hey, see my original post. After a couple of days it won't be rock-hard, but it'll be hard enough that you can mount drivers and move the cabs...gently.

I put a heater in my work space and got it up to about 90 degrees. Could apply the 2nd coat after about 40 minutes.
I did let the duratex harden up for a few days before I stated moving the cabinets around.

I put two 1000+W space heaters along with a house fan (for stirring the air) in the smallest room in my house, a bathroom, got the temperature up to 120F and made my own curing oven when dealing with Duratex on Sonotubes. It still took several hours to cure the Duratex.

ps: sonotube absorbs moisture from waterbased finishes and expands noticeably which makes getting a smooth, nice finish difficult because you get tearing at the seams after it contracts.

DuraTex needs high heat to cure properly. The easiest way for the DIYer to cure it is to put the cab in the sun for a couple of days. If you don't chances are the drivers will stick in place if you ever need to pull them.

Yea, i had them under the sun roof with the hole deck cordoned off with plastic not sure how hot it got but it hardened very quickly.

I would like to paint my sub cab with a metallic furniture paint by Rustoleum. If I am not happy with the results I plan to paint duratex over it. Does duratex stick on previously painted surfaces?

Speakers: Boston Acoustics VS260, VS325C
Subwoofer: Dayton Ultimax 18", Behringer iNuke 6000DSP

I am not sure about it, I have some rustoleum somewhere and if i can find it i will try duratexing over it to see what happens. I take it this cab is MDF?

So far i have only done two speakers in duratex, one pair of 5 cuft and one pair of 2.5 cuft. Neither of which had ever had paint on them before so i sanded, dry wall spackled then painted (after brushing the dust off).

Yep, it's MDF. I have some duratex but I haven't unpacked it. If the furniture paint looks good I plan to return the duratex.

It appears that deck restore paint gets better reviews for speaker use than actual deck use, lol.

With that said, I'm still very happy with Duratex.

I'll try the rustoleum only if someone can confirm that it will adhere to enamel painted surfaces...
