Painting Trim Using Lacquer Toner. FISHEYE RESOLVED!

What happens here

The root cause of the widespread 'fish eye' problem was identified when the customer revealed they had recently cleaned the wood trim with lemon oil. The speaker issues a strong warning: lemon oil is one of the worst products to apply to wood trim if there's any intention of ever refinishing (re-clear coating) or painting it. Products like lemon oil leave a residue that is highly incompatible with lacquer and paint, leading to severe adhesion issues and the formation of fish eyes. This highlights the critical importance of knowing the history of surface treatments before attempting any new finish.

Goal: This step reveals the cause of the 'fish eye' problem – previous application of lemon oil – and strongly warns against using such products on wood intended for refinishing.

the top of that glaz yeah so you kind of just have to just deal with the situation as it goes and then I did the one door jam called the customer in said is this going to be acceptable to you if not we're going to have to do something else the customer really liked it and so we just continued going on with where we were we're going to be showing you in this video some video footage of us using toners and how we're going about using it and spraying it and leaving it and just spraying it and then back rushing it but the fishy problem we were John you were spraying with one of the doors and you kind of noticed something and asked had a question and yeah you know start to spray one of these doors in the fish eye you could see it in kind of a swooping pattern and typically when you see that contaminant you'll see it in a couple of places specifically um but that the the the swoosh was a little un ual swish swoosh swirl white Mark White Mark and so we we came to find out that um in the recent past it had just been had lemon oil applied all over the yeah and I think I think John even asked me I think it looks like somebody's um wiped these things down with lemon oil I went and contacted the customer who's prepping this place to get it ready to be painted and um all the trim being painted and stuff and I asked him what cleaners they were using to clean and get ready and they said lemon oil and lemon oil is one of the worst things you can ever put on your wood tram if you're ever thinking about Rec CLE coating it or ever thinking about painting it you never want to put any type of lemon oil on it and I just recommend to the customer just you know for the rest of the project just to clean it with warm
