No, mist coats don't build as well. You either thin by 50% and put 6 coats on or don't thin and apply 3.

I'd agree with this. Actually, use a brush and you will do it in two.

Personally i use a sealant, breeze blocks just keep taking the paint.

Well...in our case, two coats covered it. Which would be the equivalent of sealing and doing one. & I bet after one, it need another to get the bits that didn't quite work!
Seriously: brushing is hard work (versus roller), but you can work it in better....

Did this last year on my double. Proper grudge job, hated it. Watered down white emulsion was fine. Using it neat was an utter nightmare, you’ll see.

I did my Garage recently, 48m2. First side wall I sealed first then used used sandtex masonry paint, took 3 coats to cover fully.
I then applied sandtex direct to the blocks on the other walls, took 3 coats also. So no point whatsoever in sealing first. I could have left it at 2 coats, but my OCD knew it would be much better covered with a 3rd!
I also applied with a brush. Roller just didn’t cover properly at all. Brush I could apply thick and work it in.
Took me about 100 ltrs of paint in the end! Good job it was on offer at screwfix!!

I did my bare breezeblock garage with Sandtex smooth white paint and it looks ace in my opinion. The (detached) garage was very old and dusty when i got the house so I did my best with a wirebrush to get all the dust off the bricks, painted with watered down pva which seemed to do a reasonable job but didn't really seal them as the first coat still soaked in quite alot. the paint was more expensive than cheaper normal emulsion but i think it looks better and is more durable than the normal paint i used for a previous garage.
i used 3 coats but wanted a perfect finish and the 3rd coat was really to sort out any imprefections and bits i wasnt happy withhe second and 3rd coats i really slapped on in large amounts.

a 7x3m2 by 3 meter high (roughly from memory) garage took me 25l. The prices on the paint vary alot but it cost me about £60 for 3x10l tubs.

I will post a pic up if i can figure out how to do it and any ones interested?

2 coats of the cheapest white emulsion I could find. I used a large "fence" brush so I could work it into the holes etc.

Hard work, but satisfying once done ! Reduced the amount of dust in the garage dramatically and it was amazing how much brighter it felt.

What are the pros and cons of using Sandtex versus emulsion?

My garage is under my house (a terrace of houses built on a concrete-framed and based structure, with wall infill done with breeze blocks, as shown below. What paint type do people think would be best for this?

Use cheap boggo emulsion. Don't bother watering it down but do use a masonry brush instead of a roller for the first coat at least.

Y'all probably laugh but I recommend you get a 12 inch plastic plastering blade, mix up a nice creamy mix of fine sand cement. Skim it over the breeze blocks and fill that surface. Its real quick. Then paint it. You'll use way less paint, much easier to paint & have smoother wall.
