Pro tip: You're probably mixing your mortar too wet for brick veneer

I see a lot of guys, especially on residential jobs here in Austin, using a soupy mix that's great for block but causes bricks to float and weep. For a standard Type N mix, I aim for a slump around 3 inches, which holds its shape when you grab a trowel-full. It gives you way more control on the wall and cuts down on cleanup. What's your go-to consistency for face brick work?

Man, you are so right about this. It feels like a lot of trades now just aim for the fastest, easiest way to do things, even if it hurts the final job. I see it everywhere, not just with mortar. People use the runniest paint, the thinnest tile adhesive, whatever gets it out of the bucket quickest. A proper stiff mix takes more muscle to spread, but that's the whole point. It means the material is working for you, not against you, and the finished wall will actually last.

My old boss in San Antonio used to say a good mortar mix should stand up like peanut butter, not run like pancake batter. He'd actually make us do a test patch and if the brick slid more than an eighth of an inch, we had to re-mix the whole batch. That stuck with me. A stiff mix is just so much easier to keep clean and you get way better lines.

Yeah, and it's not just about looks either. Like @nancycooper said, that runny stuff fails faster. I've seen mortar wash out in a few seasons on a garden wall because it was too wet. Same with grout in a shower, it just turns to crumbs. A stiff mix locks everything in place for good. That extra effort up front saves so many headaches later.
