Glen,
Not all boards pickup epoxy equally but depending upon how it was sawn some can pick up a lot. I have experienced this and I had to make multiple batches because it would keep sucking epoxy away. This can be bad for a lamination or a joint glue up.
West System recommends a 2 step process, first being a wetting process. One can wait as long as the open time before applying the 2nd coat. If it did not get sucked away in that duration then it is likely to remain where needed for the time required to cure.
I assume this is a structural element, it may be best to consult with pros. I know melamine urea formaldehyde, phenol resorcinol formaldehyde (dark color may not be desirable) and polyurethane are used by industry but not sure of conditions that guarantee the structural strength.
West System does publish ASTM test results for their various products on the website but do not mention which particular ASTM test and for this reason it is hard to find test results that can be compared.

?All,
As you know I have been injecting the West System in to my totem pole for weeks now, not sure where it is going but The core of this log is a lot worse than I though.
At this point I am just trying to seal up the sides so I can invert it on the the head and do a pour down the inside.
That not my question, but in the time i wait for cure and to do it all again, i made the mistake of thinking.
How would the West System work for lamination?
I have a project coming, making some arched glue-lam rafters so to speak which I have done before and use Gorilla Glue, These are big enough that I am sure I can"t coat and clamp before the glue starts to go off.
Any thoughts on the bonding strengths, outside application on trying this.
Thank you all In advance as always
Glen
