Best way to glue bitumen pads.

oon_the_kid · 23rd February 2011, 02:01 PM

Hi,

Just wondering, I bought some bitumen pads to help dampen the vibration on the speaker cabinet walls (cabinet resonance). It already has adhesive on one side. I am wondering, what do you think is the best way to apply it? Should I use it as it is or should I add in extra glue?

My cabinet is the sealed type.

I have ad excellent results using 3M's glue adhesive in spray. When the already glued part is applied to the non-dried sprayd glue it melts and bonds as one. Experiment with it on a small wood surface before applying in your cabs.

If they come with pressure-sensitive adhesive already you'll probably be OK, however I've experienced some peeling in the past.

Make sure you press hard all over the sheets and avoid leaving any air bubbles - you might try using a dough roller or veneer roller to do this, if you have room in a pre-built cabinet.

It's also a good idea to lightly sand the areas of the panels where you'll be applying the sheets, to provide more surface area for the adhesive to grip - just make sure you remove all the sanding dust before application.

Finally, if you want to use some extra adhesive for a little added peace of mind, a small bit of contact cement from a tube or spray can has worked well for me also.

Just give the adhesive fumes 24 hours or so to clear before you reinstall the drivers, or they may damage them

I use bitumous paint. You just paint it on and you can use it as an adhesive to glue foam/other damping inside the cab. It also works out cheaper than bitumen panels.

This is the stuff I use, I'm sure there is something similar available in your vicinity:

I've always had trouble with them peeling over time. Try a staple in every corner.
