hello,,,im on renovating my gable end,,,the paint which was on it must have been on for a few decades I reckon,,,a lot of it was almost falling off,,,spent weeks removing it all with a turbo jet wash and loads of patience,,,i now have a fresh clean sound tyrolene surface,,,so I was wondering what next to paint it???,,,do I put the masonry paint straight onto it or is it best to use a watered down version for the first coat???,,,and what about weather conditions???,,,whats best to paint in???,,,will it dry too fast in the sunlight???,,,is it best to do it on a cloudy humid day etc???,,,should I put some anti fungal stuff on first before paint???,,,any advice from you painters who are in the know greatly appreciated......
