[Closed] Painting inside garage

I just used white emulsion on my breeze block. I was told later I should have put some pva glue in the paint to stop it soaking into the brick so easily so I needed 2 coats. I used a shaggy pile roller.Do the ceiling as well 🙂

I wallpapered mine.

ceiling is asbestos, will i die?

Shaggey roller.

Cheap emulsion watered down for a quick first coat, Normal emulsion or sandtex if you prefer

Yes you will die (eventually we all do)

Definitely seal the surfaces with a watered down paint.

I just used Wickes masonry paint on the inside of my garage. It went on fine, but required two coats - first coat was a bit wishy washy.
I used a large brush rather than a roller. Only got one wall done so far - too much crap to get out of the way on the other walls!

Don't be lazy and always do two coats. I have typed and am correct. End of thread.

Mine took ages and ages, blockwork and brickwork just soaked it up, was using some left over masonry paint.

Didn't use pva in your paint see for an undercoat 🙂

Ok, so going for watered down emulsion then masonry paint.

How much watered down is watered down roughly?

Why on earth do you want to paint it?

Personally I'd board it out then paint it if at all. I'd be concerned about damp lifting the paint and it looking patch. At least bare brick looks intentional.

I think you've got most of the answers above.

Watering paint down really depends on where you start from. There are people (like me) that spend time getting the consistency of paint right so the balance between application, thixotropy and final appearance is as good as it can be.

I'd say it won't need much water. You'll be trying to get it to look like a thick "wash". You don't want to go so far as for it to look the same consistency as water but I'm struggling to think of anything to compare it to. My suggestion would be not a lot. Get a separate mixing pot take some paint out. Add a little water mix and see how it goes. You want something to wet the surface easily and soak in but not just drip everywhere. Experimentation is the key.

Prep is key so make sure the surface is free of dust, grease and dirt. Check the temperature (humidity, dew point, and substrate temperature 😉 ) as a lot of paints, particularly water based don't like <10C. I'm holding off on a few jobs until it warms up.

25% water (ish)

Chuck some PVA in to if you like. 5 litres is cheap at Screwfix compared to B&Q and it won't hurt the undercoat
