blue board joints
Does any one know what products you use to hide the joins in harditex blue board sheets. I have just made a garden wall and have 1 join on a feature wall that I need to cover up well. Also do you need to seal the board or does painting suiffice?

Dulux have a system for trowlling blue board joints to a waterproof paintable smooth finish. I cant remember the name of it but have used it and it does a great job.
The base coat is acrylic and the top coat is grey and sandable.

I used Acratex - this is a cement based product by (I think) Wattyl. I found that no matter how much I tried to smooth the joints, they were always noticable in 'glancing light' - ie from the side as the sun set. There were 5 joins each 3 meters tall and even after using a grinder to try to feather the joins they still stuck out. I ended up redoing the joins and then spreading a light smear of the compound over the whole surface so there was no break in the texture where the joint compound finished and the sheeting was exposed. The whole lot was then painted with a textured finish.
