Three Year Old Slaked Lime Putty For Sale

Written by Andrew Morrison

Plastering straw bale house with lime I recently received an email from a gentleman named Curtis in Kansas who has literally 10,000 gallons of lime putty he is looking to sell. He used the lime to make custom plasters in his company for the last few years; however, the slow economy has forced him to close his doors. Once whipped up with a paddle, the lime putty reaches a beautiful, creamy consistency as shown in the photo. The putty was all slaked with water and mixed in a 300 gallon stainless steel mixer and then placed in 55 gallon drums or 5 gallon buckets to age. The lime  has great plasticity and consistency, is high in calcium, and is sourced from the Mississippi Lime Company in St. Genevieve, Missouri. It actually looks a bit like tofu before it gets whipped up…delicious!

Lime PuttyThe putty is all shrink wrapped and on pallets for easy transportation. They have a forklift and can assist with loading at their facility; however, all shipping arrangements are up to the buyers and all orders must be picked up from the seller’s facility in the Wichita, Kansas area. The putty has been stored in a temperature controlled warehouse and has never been subjected to freezing temperatures. They are currently selling the putty at $2 per gallon which is a very good price for such yummy lime putty.

Keep in mind that if you plan to use lime putty in the US, you will have to make it yourself by slaking hydrated lime. This is a slow, laborious and often dangerous process so you are much better off purchasing the lime pre-slaked. Unfortunately, there are not many companies that offer pre-slaked lime in the US. THat makes this deal even better. What’s more, the longer the slake, the better the putty, and three years is a very good time line for quality lime putty. Obviously shipping will come into play in regards to price, but I think it is still worth the effort and a good value. If you know others in your area in need of lime, perhaps you can share the trucking costs. You can reach Curtis to find out more or to place an order at this email address.

  1. How many gallons of this pre-slaked lime would would a 1200 SQFT straw bale home typically need to use?
    Also, is there a time limit to how long it will remain usable?
    These are 3 yeas old now. If it took 2 more years before these were used on a project, would it still be good?

  2. I’m not sure how to estimate the number of gallons you would need. Sorry. Perhaps they can help you figure that out or you can find a coverage chart somewhere on line. In terms of the life of the material…lime putty will last forever as long as it is covered and not exposed to the air. In fact, the longer is sits, the better it will be.

  3. Andrew is correct, as long as you prevent the lime putty from drying, it wont carbonate and will indeed improve.

    You will need 40 us gallons mixed with a dumpy bag of sharp sand 2000 1bs(900kg) this will cover 540 sq ft at 2/5th inch (10mm) This is a 3:1 ratio by volume.

    Get back to me if you wou like more help.

  4. I would imagine there is still some available as of today (April 17, 2013). I suggest you contact Curtis at his email address which I linked to in the article. Good luck!

  5. i have built an earth wood fired oven , and would like to plaster it with lime that has already been slacked. Need ten to fifteen gallons which would be plenty for future repairs. Would like to order some. Please contact with info on how . Thanks .

  6. Hi Haven. Please send and email directly to Curtis to connect on availability and pricing. his email is at the bottom of the blog post. I don’t have access to that information. Thanks!

    On another note, be sure that the lime will adhere to the earthen oven. I see a LOT of issues with the use of earth over lime.

  7. I know this is 2 years after publishing this Article about lime putty but I was wondering if there was approx 5 gallons left. Wanting to teach the buon fresco technique for an art class and looking for lime putty. I could not find the email for Curtis you mentioned was in the article So I am contacting you.
