Hi guys
On a job at the moment and the background is quite uneven . Normally I would give a base coat in Ocr before topping with weber pral m.
I've got a load of parex scratch render off other jobs , could I use them as a base coat then top with weber

Do you dampen down the OCR before topping with pral or go straight over?
