I have only one frame of plasticell which I got with a NUC I purchased and it seems to be working out okay

However, yesterday I was at a new beekeepers house and they had purchased a kit that only had plasticell in it for the hive body and super frames.

We went to help them look at their hives yesterday and almost every single frame had wacky comb, that was sort of rolled over exposing the base plastic.
I'm wondering if they should have brushed melted wax onto the plasticell to help the comb to stick?
Anybody know about this product and how to use it or run into that issue?
It was a shame but the rolls were actually attached to the tops and bottoms of the frames as well as bulging out from them. We had to cut it all off, and there were bees hatching and larva all over the place. I think the new Beeks may have forgotten to check the box after they added the next super.

They called us because last Saturday they had a swarm about 40 feet up in their woods and wanted to know what to do. They had also brought home a baseball sized swarm remnant from their workplace and just put it in the used NUC box with some plasticell (not in frames) leaning against the wall. Hopefully today, they will get more frames put together.

As I recall my husband used those plasticell frames once and they had wax coating them. The bees didn't seem to like them so he's not using them now.

The plasticell did have some coating on it, maybe it didn't adhere well to the product and that's what caused the rolling. I told them to try and phase out the plasticell, maybe they will do so. The husband didn't seem to happy about the bees, he said it was the wife's idea and so she got the hive kit for Christmas, but he is doing all the work.

We've found that the bees don't like the plastic frames. We do use the wax coated plastic foundations but some you order don't have enough was on them. You need to rewax these. We are going to a three quarter inch waxed strip in brood frames. The right combination of bees will draw the comb in no time. By just using the strip, in makes it a lot easier to recycle the wax when it gets dark colored.

Why would you recycle the wax when it gets dark colored?

For one thing it means the cells are well used and could potentially harbor mites or diseases. The insides get larger due to all the garbage left in them by successive generations of bees and the varroa love that.
Also it is a big attractant for wax moths, all that leftover protein
For them to dine on. It also seems to more susceptible to mold and mildew if the weather is wet or very humid

I haven't had too many problems with new plasticell frames, but the older ones do tend to get tunnel comb. I generally use medium wedge frames without foundation, or deep wedge frames with either 20 lb fishing line for reinforcement, and alternate one piece plasticell frames in between til the bees get the idea. I suppose I may need to recoat the wax on some of my older plasticell frames at some point

I'm sorry to be so slow getting back to you with my reply on the wax. Just because the wax is dark doesn't mean you can't recycle it. When you melt it down and strain it you get most of the stuff out that turns it dark. Usually melting and straining two or three times gives you beautiful yellow wax that you can reuse in your bee keeping or if you have enough, sell it. Candle makers love bees wax.
