acid etch before painting concrete slab (workshop)?

[JDub]

JDub,
I'm currently researching paving paints etc. You did the right thing by acid etching. Acid etching apparently dissolves "latience" which I understand to be a thin layer of weak, powdery concrete that rises to the surface of a new slab during the curing process. Paint won't stick properly to it. So you're good to go. By the way, are you using a water based or solvent based paint?
Cheers.

I was actually walking out on the slab yesterday and noticed much of it was covered with a very fine concrete dust from the etching process.... so yep its probably done more than can be seen with the naked eye, I am glad I wasnt as lazy as I normally am and actually did it

Im using solvent based, Its White Knight brand (I think) Paving Paint.... clean up in turps... but I have a fair few old rollers so I reckon it will paint then chuck the roller...

I will post a pic in my Shed WIP thread next week once I have painted it.

Cheers
Joel
