: : Dear Ken,: : This is one of those times that being wrong will work out for the : best.: : Even though logic says the veneer is saturated through and through, : if you sand and scrap the veneer well it will come clean. Ive have : done it many time without any problems.: : there is something that might not come clean though. On occasion : ureas that bleed through excessively, especially on maple, can leave : a yellow stain that cannot be gotten out.: : The long term solution is to back off the amount of glue you are : using. You should have almost no bleed through on maple when you get : it right since it is a closed grain wood.: : Sincerely: : Darryl Keil: Darryl - thanks for the fast reply. Yu mentioned something that : turned a light on. I was assuming the splotches of yellow were glue : that bled thru. Maybe it is urea and not glue that I'm seeing. I : have sanded it thoroughly with 220 paper but not tried a scraper : yet. How do I know how much to scrape/sand before I can conclude : that the yellow is urea? If it is urea, am I stuck?: Thanks again.Dear Ken,A couple of things. First, 220 grit paper is not anywhere near enough to remove any glue bleed thru, you must scrape. Nice full strokes with the scraper, dont concentrate in one small area, that is how you go end up going thru. If, after you have scraped the panel clean of bleed thru you see yellow staining, this is a chemical reaction between the glue and the veneer that cannot be removed. Its not urea but a chemical reaction.One of the best ways to get the feel of scraping a panel is to lay up a scrap panel and scrape it until you go thru. This is one of the best ways to get a feel of how much scraping you can do. You can scrape a lot more than you think, but actually scraping thru will give you a good sense of it.SincerelyDarryl Keil
