I'm new to this so not sure if I'm in the right place for seeking advice, but here goes.
Have a place in central Portugal (near Tomar), that we'll be moving to permanently in the near future. I've got several outbuildings that I have plans for. The inside of all of my outbuildings are bare brick or cinderblock. My question is this - would I use the same or similar materials to plaster the insides of these buildings? (I'm not a builder but a competent and confident DIY'er). In similarly built outbuildings in the UK I have used a base coat of sand & cement (6-1 with plasticiser), then 2 coats of multi finish. In the house, depending on the conditions I'd either skim with multi finish or use plasterboard then a top coat.
Sorry this is a bit long winded, but can anyone offer some advice re products and method. Thanks in advance
