Questions & Answers

Ask a Question

  • I have a bag of this already, previously ordered. Can I mix any dye in with it? And also, when it finally sets up, should I be able to scratch it with my fingernail?

    Iron oxide pigments can be added up to 5%. We recommend using solomon colors which is designed for adding to mortar mixes.
    No, once the mortar is fully hardened you should not be able to scratch it with your fingernail. In rare situations where a soft mortar is needed we would recommend using the NHL 2.0 or the Lime Putty as the binder then adding your own sand.

  • Good Morning, I'm in the process of working on some tab stones and slotted bases. I noticed there is a special lime mortar for this repair. My issue is the shipping for the large bag is outrageous. Is there anything you could recommend that I could buy locally from Home Depot or Lowes?

    I can't say what products may be suitable from your local hardware store, but we do offer the historic pointing mortar in 1-gallon buckets which should be more reasonable to ship!

  • How does one chose the type of mortar for a headstone fitting into a slotted base?

    Typically for reseting a headstone into a slotted, or keyway, base we recommend using moderate strength fine. High strength fine will also work.

  • What do you suggest for a keyway with greater than 1/4 inch space between the keyway and the table stone. Tablet is marble and the keyway is granite.

    You can use the historic pointing mortar - moderate strength fine - and build up the areas around the stone!
