Using 8 year old masonry paint - bad idea?

[dangti6]

Usually I'd probably not give this a second thought, but having recently used expired silicone which failed to cure, I am wary.

 

I have a large 10l tub of white Sandtex masonry paint which I bought 7 or 8 years ago. It's unopened and hasn't been stored in freezing conditions.

 

If it's deteriorated, what negative effects could I expect? It's to throw on some internal blockwork to brighten up a garage opposed to being used externally where I wouldn't take any risks. When I open it, if it looks like paint and smells like paint I will probably hope for the best at £35/40 a tub.

Doing it for a client? No, don't take the risk.

For yourself, go for it.  

Worst that could happen would be adhesion/colour change I reckon. Nobody dies.

For myself. I have done 2 coats of 'fresh plaster paint' which is fine but no doubt I will be making a dusty mess out there over the years and I figured as I already had this stuff, a 3rd coat of that would give me a more washable layer whereas the emulsion would probably get dirty quite quick and smudge/rub in when wiped.

40 pounds is not worth taking the risk.
