Hello everyone , just wondering has anyone got a solution to my problem !! We have always used a machine to apply the parex monorex render and there's never been a problem . Changed companies now and were hand applying the stuff and every so often I'm having these small lumps and bumps on the panel .they seem like little air pockets , so as I notice them I scrape the lump out and lay it back in but I'm not sure if there's an easier way around it . Are we mixing it too stuff maybe ? I don't know !! Thanks for any replies
