I am planning some work during Dec/Jan involving scaffolding, and taking the opportunity to touch up my exterior render.
In the past I have used Sandtex masonry paint but the specs state not to apply below 8 degrees C.
Is there a suitable paint for lower temperatures?
How critical is the 8 degrees limit?

Cheers All

Water based paints cure through a process called coalescence. As the water evaporates off, the product shrinks down and the elements bond together. If the water freezes, the whole process fails.

If you are applying water based emulsion on a sunny wall and the temperature is above 5-8 degrees for 4(?) hours, on the balance of probability, you will be OK, but there are no guarantees.

As @Wayners said, you can use a pilolite paint. They are oil based though.

If you are going to be using exterior oil based gloss paints at that time of year on woodwork, I would recommend that you gloss about 10am and stop about 2 pm. When the early dew comes down it will make the gloss look like eggshell. I once had the misfortune of doing two exterior jobs that ran through the whole of winter (over two consecutive winters). You may also find that any oil based gloss will be a pig to apply. Keep the paint warm and consider using an additive such as Owatrol oil to help it flow.

I'm painting external pebbledashed render during January so my original post was asking for advice on the most suitable paints for application at low temp. I obviously need to avoid water based paint if it is particularly cold.
