My neighbour has just kicked his builder off the job after i had an argument about his attempt a weber rendering. I've got to do it myself now but I'm not sure what product or brand I need to use. I want to use a thin coat silicone render so will need to prime and base coat. What's the best brand? Weber, ceresit or parex? I am a plasterer but haven't used much of the acrylic stuff. This is a rough idea of what I've got to deal with
