No mine had old render knocked of so i just sprayed the wall to get all the dust of the day before putting the beads an s&c scratch coat and then waited a few days before doing the knrend then scratched it back the next day mate
Did a k rend job about 3 weeks ago and it's been a really cold day today an grey patches have appeared does anyone know what this is , it's never happened before so I'm a bit confused, all the k rend was applied to the right thickness and scraped the next day can anyone help
thanks

Hello,
can you use weber pral m as a monochoce on to brick that has had render nocked of ? Or do you need to apply a sand an cement scratch coat on to the background or can you use a bonding agent ?
Thanks
