Just finished pressing a large job. Sipo veneer- similar to sapele.
Very open pores. The glue remains in the pores even after an agressive stroke sanding. Will not accept any clear coat (which was specified) it highlights the glue. Blocker was used. Any thoughts on my current situation? Anything to do next time?

Difficult situation to be in. As far as I know,no sanding will remove that. I'm curious..what was the glue application process like? It sounds like this was applied too heavy, not that this observation helps you in any way. Did you run samples in the press prior to committing to the entire job? Are we talking about 100's of square feet of veneer involved? My only thought on saving this would be to add a toner to your clear coat in order to blend out the surface but again......difficult situation. If a "clear" coat is specified, maybe that's unacceptable. Wish I could offer some miracle cure...maybe someone else can but.......good luck.

Chris,

Talked with someone else about this veneer recently, said it was very open poured. Although the blocker will eliminate bleed through on most veneers there are some, like the one you are using that no amount of blocker will prevent the pours from being filled. The only real solution is to either use the dark catalyst and if that isn't enough then tint the glue with water or alcohol soluble aniline dyes even further. You want to end up with filled pours that have a color close to the final stain color.

I know this is no solution to the current problem as the glue will not take stain, I'm only giving you a future solution that's pretty easy to do.
