You said your using acrylic there’s two different things. I find it hard to believe you’ve been applying render systems for 30 years based on your question, you mean in 30 years you’ve never rendered in winter and used an accelerator? I’ve not got aggressive you’ve F*****g wound me up with stupid questions. Why do you Think it would be ok to put one manufacturers accelerator into another top coat!!!I am using silicone,I haven’t got the stuff left over in a shed and I’ve been applying all render systems for over 30 years.I am very proficient at my job and was asking a simple question as I’ve never put accelerator in silicone render,why you’ve got so aggressive is a little bit confusing.The weather is f**k**g killing me as well as everyone else at the moment and I’m just trying to get a job finished as we’re I’m not getting 2 dry days in a row.Thanks for your positive response in these trying times.
