advice blueboard can it be painted

[ceaser]

Hi guys some advice, I'm building a fence and putiing blueboard.
Q Can i paint sraight on the blueboard with stone finish paint.
Or it has to be rendered first.

I put up blueboard last year and the accepted method was to fill the joins, apply a skim coat, then a render coat, then paint it. You would at the very least need to fill gaps and apply a skim coat for it to look ok I reckon, but I'm no expert.

The key to it, like anything, is the prep. As long as the frame is ok and solid, the timber will not shrink/expand to great levels I would do the above. A skim coat plus top and texture coats, probably the mixes you buy in the bucket which have semi-flexible render for covering joins
