Copper Sulphate, so far so good

Now for a little experiment: While I was looking for information on staining concrete I found that most of the brown stains contain some form of Iron Sulphate. It just so happened that I had a left over bucket of Copper Sulphate that was used for weed control in our pond. Hmmm, copper instead of Iron... blue instead of brown... I found a couple other forum references and figured "what the hell, I'll give it try". I can always cover it with epoxy if I don't like it. I'm sure some will love it, and some will hate it. I think it looks great. No real reason to do this, other than the fact that I had the Copper Sulphate, and I just like trying different stuff. Although, if it lasts, it only cost me 87 bucks :)

I mixed about 5 gallons of water with 2 quarts of crystals and kept stirring it every few hours for a day or so. I used one of those 1.5 gallon hand pump sprayers to apply it. I did 3 applications, brushing off the excess powder between coats (wear a good respirator, it's not deadly, but it is an irritant). While I like the look I have, 1 or 2 coats would give a lighter blue/green.


Once it was stained, I put down a coat of "Kure-N-Seal W". Basically it allows you to seal your concrete as soon as the surface moisture is gone. They claim it slows the curing process ( read stronger crete) and protects the surface. It was perfect because there is no way I'm waiting 28 days to seal it. I need to start using the shop, and once I put my sh*t in the shop, I'm not taking it out 30 days later to seal it :). I know, I know, it's not optimal concrete protection, but I figure the worst case scenario is... the garage sinks and I build a new one. It'll basically be a wood shop / metal shop, so I don't really need industrial protection.

The sealer goes on milky white and dries clear. It was a little scary at times wondering what the final outcome would be. It went from ugly white powder, to blue/black (with clouds?), to the final blue/green copper I was hoping for. So the slab was poured on Friday, and I was ready to move in on Tuesday, sorta ;)

I didn't want to start a "new garage" thread because I tend take take YEARS, to complete stuff, but I thought this came out really cool. More pics HERE.

I'm working on something similar. Won't have any pics for a couple of weeks though.

I like the way yours turned out, it gives me hope for my project. Nice mottling. I'm curious if yours will continue to change as it cures.

Wow, I like it. Wish my concrete was nice enough to just do something like this on it.

Walk into a bass pro-shops and look down,it may look similar.
Spanish Fort, AL is the last store I have seen and its nearly identical to your garage. Of course the sealer is an epoxy ;)

How long will it remain blue? The blue stuff is copper sulfate pentahydrate. Anhydrous copper sulfate is white. When the water of crystallization is lost, it will turn white.

Dunno, I'm hoping the sealer will make it last, but that's why i titled it so far, so good ;)
i was actually amazed the bucket of crystals wasn't white. Its been sitting around for close to ten years.

UV light will not affect an inorganic metal salt. However, loss of water will. As long as there is bound water, it will remain blue.

Very cool. I'd be interested in seeing how it holds up as I really like the look.

Kayak for the name, life preservers along the wall, I smell a nautica themed garage. Hang some old thick rope along the walls and a tiki hut bar in the corner.

Looks great!
