is it just me or has anyone also noticed shitloads of air holes in scraped render lately ?
If you prime walls it will help mate ! You need to catch the render a bit softer it will stop the problem
The reasons can be so many.... I just gave up. My best guess will be too thick top coat. Once you star ruling it off it moves down and creates lots of problems hence I always try to put more with the mesh. All this can be cured with the right suction and good timing when to hit it. In my opinion key coat has very little to do here. But try to hit it late with the ruler and you can be in much biger troubles. Go and figure it out. I am scratching my head every time it happens and adjustments are needed.
Just blocks mate it’s as soon as we started next day scrapes and has happened on every job we’ve been on, we’re not even brushing it anymore cause it’d just get stup
you don't get them same day scrape ? Like I said it's because the render is to hard
