Which mortar for blast stone wall?

[Joniblom]

Hello!

What do you experts or experienced people say:

Which mortar should I use to grout a wall made of blasted stone?
There aren't any major forces on the wall, and I have the drainage under control. I'm just wondering which type of mortar is best for pointing a blasted stone (granite) wall.

Thanks in advance!

This one, for example, cement mix?

"must not be used in statically load-bearing structures," which is the definition of a wall, so it's probably not suitable.

Cement mix A?

"used for minor repairs," that's not perfect either.

Masonry mortar M2.5?

the one that should be used?

Hi! I've just finished constructing such a wall and did the grouting with Cementbruk A from Bauhaus. It turned out really well and feels very stable after that. It took 12 bags for this approximately 5-meter-long wall.

But look at that, it turned out nicely too!

I'm testing Cementbruk A or alternatively Murbruk M2,5, possibly holds up better against frost. I guess it's important to have completely sealed joints to avoid frost damage?

As a beginner, you learned a few things. Among other things, you should take the calculated number of bags of mortar and multiply it by x2. Here is the result.

Nice job, it turned out very well

Thank you Mr. Lee!
It took a heck of a long time when you're a perfectionist. But now it should stand there for a while.

Are these kinds of walls frost-resistant? Or does the mortar release? How should the stones be cleaned before masonry?
