So I finally got around to painting the floor this weekend in SikaFloor "Stone Grey". Two coats were applied - one on Sat. & one on Sun.
The result came up 'OK', but If I was to do it again I'd be a little more carefull with the application process...
For whose who may do this in the future, this is what I did:
The concrete was troweld off smooth (but not too smooth) when it was laid down.
6 weeks later (giving it time to cure) I had it ground to take the high spots off & to open the pours of the concrete up more.
A week later I acid eched the concrete with a 4:1 mix of Water & Hydrocloric Acid, then blasting it off with a pressure cleaner to nutrilize the acid.*
I then repeated this step twice more giving a solid week of drying time between etchings.
The paint was then laid down over the weekend with a lambswool rollar.
*(interestingly the first time I did this a LOT of brown 'muck' was ejected from the concrete, but decreased over the last two etchings...)
Two final jobs to do are finish hooking up the guttering downpipes & pumping expanding foam in-between the slab & the wall sheeting to stop the ingress of pests (like Salty).
And that is the end of this story!
I hope everyone gets a few ideas from my build - so any questions & comments are welcome
Cheers!
