Answered on 31st May 2022 - Member since Apr 2022 - report"Yes, you can dash over dash, but I recommend you make sure none has blown. In other words, hollo. If everything is soun,d give it a good cover of PVA, or better is SBR from most builder merchants, then scratch coat to get it flat bead up around doors and windows, then on the dash coat same as before PVA it this will hold it back as well from drying to quick that's the last thing you need apply thing coat on render and then dash don't take it too lightly its a skill to dash"
