Hi! Can anybody please tell me how to make plaster from from cement??
I’d agree in part, with Just Me, and no offense to others, but you can buy pre-mix. I’ll assume, without offense to you, that you don’t strictly mean Plaster, but a mix for perhaps doing a textured finish on the wall, similar to stucco, trowled on. You do state concrete wall, as one answer missed that, but not that it’s block, or a pre-formed slab vertical to you. Around a house I had built in 1992, the walls are block, with “cement” trowled on. No wire mesh, no lath strips. The house itself was “stuccoed” in a fiberglass blend, also trowled on, no wire mesh. After 16 years they hold up very well, only being painted once in that time. Any bag of pre-mix will explain some mixing procedure. Obviously a mix with fine aggregate. For your purposes, I’d suggest the consistency of mashed potato. The process in mixing is simple. Just set yourself up with the proper tools, some container to mix and scoop from, add water slowly until a consistency is achieved, and have at it.
