- How to mix mortar using 2 different types of sand and Tigre NHL 5 (Natural Hydraulic Lime). Use a bucket to measure by volume, not by weight!
We do this mix in a 1:2 ratio- 1 part NHL 5 and 2 parts sand by volume.
Dry mix everything first. Then slowly add clean, potable water, and mix thoroughly. After it's mixed, transfer to another bucket, and mix again!
*NHL is highly caustic and precautions should always be taken, like wearing gloves, proper clothing and a mask! - Навчання та стиль
Thank you. Exactly what I needed to know! I'm off to mix some mortar.
That worked out amazing, looks like a million bucks once you were finished. Thanks for the video!
Glad you like it, and thanks for watching!
Great organised mixing set up for posting stone walls.
What would you recommend to to mix Hot lime mortar for plastering walls (Quicklime slaked with a sand) ? Do I slake before mixing with a paddle mixer, or use a Baron mixer or Roller pan mixer ?
Hi, in terms of vapor permeability ( damp regulation on old brick and mortar walls) is there a difference between NHL5 and NHL 2? I want to plaster a cellar wall.
Everybody and their mother seem to add Portland cement. I looked up NHL5 and sand, and found you. I'd love to build a cob house on a stone foundation, cement free.
What are your thoughts on stone foundations without cement in the mortar?
Go for it! We are building a stone foundation for our log house now with NHL 5 . Cement has its place, but often it is a terrible fit with natural stone/log. The British seem to have understood this for years and years. They don’t allow it’s use on listed historic buildings. America is yet to catch on, I guess?
@@Montana_Ranch_Rescue It's not as common as you'd think. Most of our old buildings aren't listed and still get re-pointed with cement
Hi . What color did you get from this mortar when dry ?
Do you need to treat the mortar after apply on wall to prevent cracking etc ?
Can you help with this on a video etc
Thanks
The color was a lavender hued brown which matched the stone.
To prevent cracking and failure you need to keep NHL mortar damp for 72 hours minimally after installation.
