Hi there,
I've just finished the first layer of render on our garage with a 4:1 ratio of sand to cement with a liquid plasticiser. I used wickes sharp sand for this layer since it said this was suitable for external rendering on the sacks.
I'm now doing the second layer, and want a smoother finish. The thing with the sharp sand was it was very gritty and quite difficult to work with for an amateur
I've just done a test patch using wickes building sand rather than the sharp sand as it is much finer... it applied like a dream, but on the sack it said it was suitable for mortar mix and interior render, didn't mention anything about using it externally. Is there any particular reason why i can't use this externally?
If i can, i would much rather use this since it is much easier to apply and gives a better texture.
