A job requires a solid color not available from any of the tape makers.

How is this best dealt with? I saw online somewhere a discussion and someone said that paintable tape, PVC or maybe wood like maple or poplar, is laid out flat on a sheet and all sprayed up, then applied.

Seems that it might be a little complicated when using a bander.

Wrap it around a construction sono tube for concrete forming.

Check Dura-Edge. Largets colour selection I know of. They must have something close enough.

As for painting before, Im not sure how well that would go through the bander without scratching it up. I would be inclined to band, then stack and spray parts if you have really cant find a colour that is close.

If I dont see something one one of my sample chains, I usually take my melamine samples from Panolam, Flakeboard, Tafisa, etc and find the closest match. You can then use the melamine colour to find the edgeband.

We do this all the time. Edge your parts, stack them and paint them. Not a big deal. If we have finished end panels or finished bottoms, edge these parts and finish them as well.

This was a real problem for us too until we came across paintable pvc banding. No need for primer - just apply your topcoats. It has saved us a lot of time and works well. You can use maple as well but you have to prime before the topcoats. We wrap around a large smooth barrel to keep the continuous roll so we're not behind the bander all the time starting and stopping new strips. If your bander is clean, there shouldn't be any scratching. If I start to see scratching, it is either a dirty pressure roller or shoe plate on one of the trimmers. We'll stop to clean these items a couple of times during a large banding. This has saved us a ton of time. I would never band and then paint as you have to stack carefully to avoid overspray and sticking edges.

We've not had good success with paintable PVC edgebanding. It's super-convenient, and water-durable. But we've found that conversion varnish is a bit too easy to flake off of it, even when pre-sanding.

We use maple half mil and wrap it around a sono-tube and paint it. Works great.

We find it insidiously inefficient to cut the parts, stack them, then spray them. Usually by the time we are cutting case parts, the paint booth isn't shooting that color anymore. Having to waste time loading that color up is not good.

For what it's worth, we also don't use this on cabinets that see much moisture. Usually it's on cabinets that have appliances with trim kits that overlip the edgeband in some small way.

I would be inclined to band, then stack and spray parts if you have really cant find a colour that is close.
