Default Can I make paper cones water resistant?

I'm using some cheapy bookshelf speakers out in the garage, and it often gets damp in there after it rains as the roof leaks.

Anyway, I can't really fix the roof as it's asbestos, so I was wondering if I could varnish the cones to stop them absorbing water?

Would this work or are there better things out there than varnish?

Mike,

Flat roof? If so it's only the felt that contains asbestos and it is hidden in the built up layering and covered with asphalt/tar. You can patch over it without disturbing the asbestos. Snap a pick of the damage to the roof and let's see what we can do about it.

What about WD40 for the cones?

Hi Mike,

I'm with Cal. Fix the roof! And if IIRC, Cal is also the man to talk to about the roof too!

I can't imagine anything you can do to make the paper cones stand up to water without impacting the sound (probably in a negative way). Water won't do anything positive either. Should have gone polypropylene (only kidding, even though the polypropylene is water resistant, the motor and the rest of the speaker won't like water). Hence, Fix the roof!

Oh, and be careful!

Regards//Keith

Rubber cement. It's cheap, readily available, and easy to apply.
Yes, it will change the characteristics of the drivers, but anything you do to make the drivers water resistant/proof will change their characteristics. Of course, you'll need to do something about the cabinets, too.
Or you could just fix the roof...

Well, it's 1am here now, so if I went and got a pic of the roof I might get mistaken for a burgler...

I'll get a pic of the roof at somepoint... It's corrugated, and it's very thin material... There's no felt or anything like that as far as I know.

Also, I'm not really too worried about changing the sound of the speakers as were free and don't really sound very good at the moment anyway... I'll try fixing the roof first tho.

I'm not recommending it, but here is something you might want to consider -

Liquid Plastic (spray on)

Plasti Dip Spray-On

Rubberize-it! (spray on)

They are all spray-on rubberized plastic coatings. Most commonly they come in can, and you dip the handle of a tool in the liquid plastic to give in a nice easy grip rubberized coating. Typically seen on the handles of pliers. However, all these are available in Spray-On.

I have a spray can of the Rubberize-it! that actually sprays a very thin coat, and could probably be sprayed on a speaker cone and the cabinet to seal it against water.

The spray I have is blue, but it is available in other primary colors and you might be able to get it in black.

These products are available in most hardware stores, lumber yards, and home supply stores (Home Depot, Lowes, Menards, etc...). Occasionally you will also find them in craft or hobby stores.

Again, I'm not guaranteeing anything. Check out a can, and decide for yourself.

Here are some links to spray and dip version - Unless they are thinned, the 'dip' versions won't work very well for you.

From Parts Express. "Wet Look". Comes in clear or black:

I'm guessing any poly wood finish would work if you are just messing around with junk speakers.
Or go high end and use Damar varnish like the full range guys put on their Fostex drivers.

Varnish or polyurethane cut 2:1 with mineral spirits. That might keep the weight down. Make sure that it doesn't dissolve any glue holding the surround, etc.
