Best practices for using Poly Bak 69 from Holdahl5/14
Can anyone share their best practices for adhering Poly Bak 69 to a lumber banded MDF panel. These are doors and wil be painted with SW cv paint. Currently we are using contact cement and rolling it out than placing it in a vac bag for a couple hours. Than letting it cute before painting. We've done it before, but with the vac bag and had some of the panels bubble. Thanks.
Hey Phil --
If you have a vacuum bag, skip the contact cement. Roll out a nice even layer of any PVA glue you can get your hands on -- yellow glue will work OK, white is good, or if you've got time order a proper veneer glue from Veneer Systems or Vacuum Pressing Systems. I am presuming that you have and know how to use cauls in your vacuum bag. If not, go to the Vacuum Pressing Systems website and find out how.
This will be easier and give you a better product than the contact cement.
Thanks John, thats very helpful!
If you don't have a problem using urea glue, go with it. You'll get a much better bond in less time in a vacuum bag.
