Protecting Oak Staircase From Plaster

[Lincolnshire Ian]

Hi folks

As we creep towards the end of the build I'm starting to think about how I can keep plaster off the oak stair parts. I have been told by several people that a splash of plaster on oak can turn it black. 

I have coated the oak elements with three coats of Osmo which I am hoping to help and then I will use delicate surface frog tape and some plastic sheeting to try and cover every part of the oak. 

Is there anything else I should be doing? 

Thanks

Our builder used X-Board Paper to cover all the treads and risers while the plastering happened.

 

Seems to be holding up so far but the key is to make sure the edges are all taped up and keeping them taped up as they do get knocked and come loose.

I have used Antinox sheeting carefully folded and trimmed over the treads and risers and either antinox again or automotive bodyshop masking plastic sheet, the type that has a static side to it so it holds its self in place, all taped with Blue dolphin exterior Masking tape, https://www.pmhardware.co.uk/product/2-blue-uv-resistant-masking-tape/ 

The tape is brilliant, my plasterer recommended it, it's a smooth plastic type finish so everything wipes off of it rather than soaking in, it sticks well and leaves no residue when removed.
