I can only say that in my experience it is better than Nitromors, so it would be interesting to know what you find it is not so good on. I'm only an amateur, so I've not used it on much. As I indicated earlier, Eco Solutions is slower, but if left overnight then it does a better job (in my limited experience), probably because as you indicate it does not dry so fast, so it can carry on acting for longer. In fact it can leave the wood damp, and I assume the wood should be left to dry out. Pros might not like it because it is slow, and the wood possibly needs to dry out. So if you are a pro decorator in a hurry, it might well be rubbish. But for home use, it's good.
Shall we now all have a big argument about which scrapers are best, and which plaster filler to use? I like Gyproc Easi-fill. Or am I just pushing a product?
nail on head about pro use and speed for sure and Eco is normally a terrible product to use on fine furniture as in the restoration game but of course this doesnt make it a rubbish product per se. For home fitting use doors skirts etc, aside from health stuff, eco stays wet as you say over night this means you can give one thick coat and leave it unlike nitromores typoe where by time you got to the end of the skirting, its dried out so you can only do small sections at a time. The main thing you have to watch with eco is discolouration to the wood. The worst part of using it is its slimy and dosnt evapourate as you rub it off. Also cos water based used on oak with wire wool leaves black staining but of course you can remove this with oxalic acid afterwards.
I suspect the main reason people ahev probs with this stuff is 1) not leaving it on long enough 2) taking the finish off with wire wool too soon (should be removed by scraper as much as possible) obviously stripping mouldings is more tricky but patience is the key
