I hope im not going mad; I found some old (at least 10 years) paint stripper in cupboard and started to strip an eggshell painted plastered wall, no worries it bubbled up nicely and easy to strip it. Anyhow the tin run out so bought some no-nonsense stuff from screwfix and its absolute carp, it don't do anything and it smells like shampoo. So my Brother gave me some "Starchem Synstrip", said it would remove anything, in fact he says you cant even buy the stuff unless youre in the trade cause its so strong ect ect. So just tried that and nothing, a tiny bubble of paint and that's it. Now im left with half a wall stripped, and the other half wont budge even with the strongest paint stripper available. Its a travesty of justice imo that the EU decided to ban the old paint stripper, anyone have any ideas ?
