Acrylised Wood

[demigod]

I planning on building my first guitar sometime and i want it to have a natural finish. |in http://www.sevenstring.org/forum/ex...n-abasi-custom-8-string-guitar-completed.html I read about acrylised wood.... and i dont have a clue what that is could someone care to clarify?
Other than that, how do i do about painting a natural finish guitar? How many layers of sealer etc i should apply?

Acrylised wood is wood with acrylates (similar to CA glue) iimpregnated into it, usually under pressure, for hardening.

Here's a page with different types with different kinds of impregnated woods.

IIRC the wood is saturated with an acrylic under a vaccuum. I think you sacrifice some resonance and lightness for incredible strength and solidness in the process, but depending on which part you do it to, this probably doesn't make a huge difference.

If anything filling the voids, and increasing the strength would increase what you are calling resonance, through a decrease in the damping. Assuming the stiffness increases to a greater extent than the density, resonance would occur at higher frequencies respectively. Damping is a very import factor regarding the amplitude of resonant peaks.

Aah i see. So it improves sustain basically?
And what should you use for a regular clear finish?

true, it would technically increase resonance, but it would shift it as well. you would get a brighter and less midsy sound, or something to that effect. really though, you wouldn't notice it much. and yeah, it would technically sustain more because of the increased density.

I don't know if you actually need a finish on it, but if you want to finish it, i would make sure the acrylic and the finish won't react with eachother, and that the finish will sit on the acrylic.

Yeah. But lets forget about the acrylised wood for a bit, and say i just whant to gove regular wood a clear finish. what paint should i use?

 

[MF_Kitten]

the industry standard nowadays is polyurethane. the older less current one is nitrocellulose. Then there's the option of waxing it, and other similar approaches.

Ok cool all i wanted to know thx MFkitten

There are some water based lacquers now that behave more like Nitro, without the health effects or some of the pain in the arse too. I know a guy who used to shoot nitro likes them a fair deal. Polys are the most durable, and resistant out there though.
