XCR Resin delamination

I've been refurbishing a kayak paddle (blades) by sanding back and applying coats of XCR laminating resin. All has been working well until I tried to apply multiple coats without the full 24 cure in-between.

I noticed in one of the easy composite videos that you can apply another coat once the first has reached the tacky stage (about 2 hours), so I followed this procedure applying three coats with 2 hours in between, then letting it all fully cure.

Now I have attempted to flatten the resin, the individual layers are beginning to delaminate one by one. Is there any reason for this?Crying
