I am looking for a reciepe for a mortar mixture suitable to use with a limestone block foundation built in 1892.
The mortar in some basement areas is coming out like sand and I need to make repairs then be able to apply a thick cement paint.
Anyone with proven success?

Check your local historical society, any heritage-type
museums, or even stonemason’s union (especially the older
guys!). Farmer’s Almanac publishers might have some
Let me do some research in my own library and I’ll get back
to you next week.

I need a motar mixture to repair some holes that I found when I tore down the ivy that had been growing up the walls for many years. The house is a “Heritage” limestone house built in 1834-36…. The mortar that is holding the stones seems to have a sandy look and texture.
I would appreciate any help that you could give me. Thank you very much…Viv Lilly

I have a house built in 1891 with the same problem. The mortar is coming out like sand. Any advice would be appreciated.

I have a similar problem with an 1895 Victorian. Old mortar flowing like sand.
I have tuck pointed parts of my foundation years ago with something I now believe is too hard: 1 part portland, 2 parts sand. In spite of the mistake it has not done too badly. A crack or two in the block. From the June 1979 issue of Old House Journal, they indicate original mixture was 3 parts sand + 1 part hydrated lime (had not invented portland yet). Old House Journal was however at that time (according to my notes) suggesting to use 12 to 20 parts sand + 1 part portland + 3 parts hydrated lime.
Would appreciated knowing if anyone has tried anything similar.

Consider this: Straight Lime Mix: 0/1/3. That would be a mix, by volume of 0 parts portland cement, 2 parts hydrated lime, 3 parts sand.
An alternative would be K Mortar, 1/3/10. The addition of 1 part portland will make a slightly stronger mortar but might not be appropiate for local limestone materal vs harder stones like Indiana limestone.
