interior shed paint in cold weather

[TryAgain1]

I have just finished insulating the inside of a standard wooden shed and although the temperature does not get that cold I really need to paint the inside of the shed.

The temperature inside the shed still varies too much from 1 degrees C to about 14 degrees C in Winter

The paint needs to be:
- Breathable, colour white (to see aswell), and able to set at temperatures of 1 degrees C. I could use paint needing 5 degrees C or higher IF I put a heater inside the garage whilst painting
-Not expensive


What sort of paint can I use? Few options I came across

- Limewash paint - most need 5oC to dry so radiator needed
- Sandtex Ultra Smooth Masonry (https://www.toolstation.com/sandtex-ultra-smooth-masonry-paint-25l/pAB650) - min 5oC so radiator needed
- Wethertex PP77 All Weather Pliolite Smooth Masonry Finish (https://www.rawlinspaints.com/produ...ather-pliolite-masonry-paint-smooth-matt.html)
- Pure brilliant white Smooth Matt Masonry paint, 10L (https://www.diy.com/departments/pur...RChAyTstdlMNK3elMGCmK3LHaTZBtZgId__IEhIfKNEL4) - min 5oC so radiator needed
- Zinsser 1Ltr Smooth White Masonry Paint (https://www.screwfix.com/p/zinsser-...nZJ8lyiw#product_additional_details_container) - 10oC needed so needs a radiator

I need the inside of the shed painted in the next week and I know this is a rubbish time for painting given the cold weather but I need to shift stuff back into the shed.

What paint should I use?

What is the substrate your paint is going on to? If you’ve insulated it a presume the paint won’t be going onto the inside face of timer, unless you’ve insulated from the outside?

Insulation is on the inside. The paint is going onto interior plywood/interior pine. No insulation on the outside (yet!)

Zinsser BIN is shellac suspended in alcohol. You can apply it as low as -1°C. (Interior use only).

Cost wise, not cheap. The second coat will cover more than the first.

Wash brushes in household ammonia.

Do not use a foam roller. The alcohol will make it go floppy.

Finish sheen- slightly lower than eggshell paint. A very durable finish, so long as you do not touch it with meths or ammonia. More durable than most waterbased finishes.

It stinks whilst you are applying it, but it is just alcohol that you can smell. The smell disappears as it starts to "dry". Inside during the summer, I expect the smell to be gone in under 15-20 minutes. I have never used in it in a shed at this time of the year though. Inside, cure time is about 3 days, waterbased eggshell/emulsion is 5-9 days, oil based upto 4 weeks- these are cure times, not times until touch dry.

Waterbased paints cure through a process called coalescence. The water evaporates off and the molecules bond down. If the temperature drops below 5°C you risk the water freezing before it has evaporated. 5°C is a slightly clumsy figure though. If you are applying waterbased paint on a cold but sunny day, you will probably be ok. That said, you are working in a shed and will not have any sunlight.

You can have it tinted if you go to a proper decorators' merchant. Colour match will not be perfect though if you are working off a colour chart. The shellac paint is slightly off white to begin with.
