Hello to everyone, New to this site, and after some advice on the Product in the heading. I've rendered over about 300m2 of old brickwork (about 110 years old, and Durisol block, in NHL 3.5. Not too many problems with that. I've been advised to use the Eco Mortar R series finishing plaster, as it apparently is more hard wearing, which is needed in the property i'm working on. I did a test with the Skim coat on Friday, and found it to be of a 'doughy' consistency, not a problem when laying it on in two passes, but I did have real problems in trowelling it up, I found that the eco mortar doesn't fill in like gypsum plaster, and it doesn't close, in the same way either. I have no experience in using this product, hence the test panel, I trowelled it as I would trowel Multi Finish, that wasn't great, then I used a sponge float, removing the fat, then pushing it back on again, slightly better results, but not what's required. The issue on this job is that all of the internal walls and party walls have been roughed-Skimmed With Sand and cement -Multi Finish, so it's a nice smooth finish, the external walls are Durisol block, which are made up of reconstituted timber, so these walls have to breath. Am I being over ambitious in thinking that I can achieve a smooth finish with the R series Plaster finish, or am I (probably) going wrong somewhere in the process of trowelling up? Any advice would be greatly appreciated.
