Questions & Answers

  • Is the gallon size concentrated.?

    Hello! We recommend using the D/2 as it comes. No dilution is required for any size.

  • how many grave stones do think 1 gallon will clean. Thanks Pam

    Typical coverage is 250-350 square feet for 1 gallon of D/2. This depends on the size of the grave stones and porosity. 
    It's estimated that 30-40 marble upright veteran tablets can be cleaned with 1 gallon of D/2.

  • Last summer I bought a monument cleaning kit. Are they still available? I can’t find them.

    Yes they're still available! https://atlaspreservation.com/collections/monument-setting-compound

Amazing results and easy to use.

I don’t know why I didn't purchase sooner. D2 works amazing and keeps working after you’re gone.

Gallon with quart

D2 is the stuff. I like being able to refill the quart for application and new spay nozzle is an improvement.

D/2 Biological Solution

I took a class in Cemetry Headstone Preservation at our local College, back in 2018. This is the product that was recommended by our Professor. I have been using this product for many years now and it is the best product for the job that I have to do to clean, maintain and correctly preserve my family members headstones. I would never use any thing else.
