EWI basecoat cracking

[i_am_fubar]

So, I may have screwed up my render.

EWI-220 base coat over EPS with mesh embedded. Applied 5-7pm when it had cooled to just below 25C.

Nightmare to apply, got grabby and pulled about the wall before I have got it flat, so the finish is hideous.

It refused to firm up by 10pm to float it, managed to wet n' rub 5:50 the next morning. But south facing wall and I'm guessing it dried out too fast and now it's showing cracks. That said, it feels solid to a knocking so I don't think it's coming off.



I've just ordered £500 worth of primer and silicone render. And am hoping I can get some feedback before I risk trying to polish a turd.

OP,
Perhaps you've attempted to do too much with not much experience?
Maybe its time to get a pro view on site because, given the poor background, & your seemingly lack of experience, then your proposal ref silicone render might end up even worse - hopefully, you can cancel or put on hold any new order?

Hey, this is practice for a pool . I have two walls that aren't really visible to practice on. Plus some offcuts of EPS to make a dummy training sheet. Going to shoot my shot

Ref the cracking, technical have advised that proving the bonding to the eps is fine and the cracks are hairline it will be fine. Lesson learned on how critical the weather is - and that's not something the pros can change
