 NHL 5:
  • Eminently Hydraulic lime is specified when strength and high freeze-thaw resistance are necessary.
  • Used for applications such as building or repairing wall head copings, pointing and parging the water table or foundation of a building and making lime concrete. Sea-bearing walls can be built and repaired with NHL 5 since it has only trace amounts of soluble salts.

    GOAL!! This NHL stuff works very well. So far the 66lb bag I got has outlasted 300 lbs of sand. I had a tough basement job, and the mix ratio I used was this: 1- 1/2 can of quickrete play sand + 1-1/2 can of quickrete all purpose sand, and 1 can of the St. Astier NHL 5 and 1 can water. Though be advised that the 1 can of water NEVER GETS FULLY USED so it is really a bit less than that.The above is a basic table that I varied. At times I went 3 cans of fine play sand+ 3 cans of all purpose sand and 2 cans lime with maybe 1&1/2 can water. Other times I bumped it up to 4.5 + 4.5 cans of each sand to 3 cans lime and maybe 2 cans water.The can size doesn't matter, but I used larger tomato soup type cans...I mean probably 3 times the size of Campbell's. I dry mixed everything in a large portable tub...then I slowly added water. Again be very careful when adding water...even my formula here is more by eye and feel as far as the water, but the dry ingredient is spot on.And I got the basic mix formula off of you tube, but tweaked it slightly.Now the nightmare of the wall in the basement is looking very good now, and I have attached before and after photos of this great product result.I will definitely be buying more St. Astiers.Always wear gloves, respiratory, and eye protection when working with this stuff.
