Question on whitewashing the coop??

[Ohio Chick]

Hello all, I'm hoping someone can help me. I want to whitewash the inside of my coop that is in the process of being built now. I've read that I'm supposed to use hydrated lime & not the garden lime. My question is where do I buy it? I bought what I thought was the right stuff but I'm not sure now. The only hydrated lime I've found was at Menards & it's a mortar type, builders lime Type S. Is that the right stuff?

Did you try it? Did it work?

No, I haven't tried it yet. I'm not sure I want to try it in the coop first. It's cost way to much money & time building the coop to ruin it possibly. I was hoping someone on here could help out before I opened the bag.

You could try it on a scrap piece of wood, maybe.

I think it will work. This is based on internet research; not first hand experience.

Whitewash needs calcium oxide or calcium hydroxide.

I think yours is Carmeuse Type S Miracle Morta-Lok Masons Hydrated Lime. The MSDS link says that is Calcium Magnesium Hydroxide.

The magnesium in it makes it take either a long time or a high pressure to fully slake. But it looks like the "type s" part of the label means it is already slaked.

A similar product for sale on Amazon has reviews that talk about successfully using it to whitewash. https://www.amazon.com/Mutual-Indus...ilder&linkId=e898669cc064fd7883b4e7cc9227b058

Thanks so much. I did try it on scrap first & it does appear to work. It takes a really long time to dry but it does turn white. Tomorrow I tackle the coop, yay!

One thing I didn't see on many websites... wetting the surface to be whitewashed helps the whitewash bond to that surface better. It was a comment from someone in Portugal - where whitewashing is still very common.

Hmmm, very interesting, nothing I saw said anything about that. It does seem to have trouble adhering to the plywood so I will definitely try that with a squirt bottle today. I would think the Portugese would know what they're talking about if they do it all the time. You've been a huge help, I really appreciate it.
