Best paint for inside walss of outbuilding?

[Lobster]

I have an outbuilding used as a workshop - it's actually an extension of the back of the detached garage - which I want to paint internally, mainly to make it brighter and easier to see stuff in my old age.

I'm wondering what best to use? Structure is single-skin grey breeze-block, and does appear completely dry; ie no dark patches on the walls anywhere. Is there any reason not to use bog-standard white emulsion, or should I be thinking differently? Presumably exterior-grade paint isn't appropriate?

Thanks David

i'd use a Dulux Weathershield/Sandtex type paint. a bit more durable (and expensive)

Well I did wonder about that - it always says "not for indoor use" though doesn't it, implying there's a reason (other than cost) not to do so?

I'd use lime paint. Its long lasting, incredibly cheap, you never need remove any because the next layer rebonds any old paint, and it tends to fill in rough surfaces, making them smoother wit each repaint. Also dried drops can be removed within 24hrs using just a hose.

Mix builder's lime with water to make a putty. Mix the putty 50/50 with water, paint it on.

Follow-up...!

I've actually already got a fair amount of white Sandtex masonry paint which has been stored in the garage for some time; including over that really cold winter a couple of years ago. In other words, I'd be very surprise if it hadn't got frozen during that time.

All paint says "protect from low temperatures", but as I haven't done, is it worth risking using this? I haven't dug it out and opened the pot yet, but assuming it will stir up properly into what looks like 'normal' paint, is it OK to use?

You will probably find that the emulsion has broken down and you will not be able to stir it back properly. That's what happened to me with a tub of emulsion. I now bring it into the house for the winter.

Well, I was using paint that had been in a room where the water storage tank froze - it painted ok and hasn't fallen off.
