I have put two coats of render on the blueboard joins and the brickwork in pics. I used Rockcote Premium Render. Is there an external top cote which I could use which is easier to apply? Any imperfection in the render is easily seen, especially in glancing light. The render mix has very grainy sand and is hard to trowel smooth. I am looking for a topcote which is less grainy. I intend to cover the wall with dulux textured roll-on paint.
I now have a healthy respect for guys who do rendering for a trade. They make it look easy.
