Mixing Sandtex with Dulux Smooth Silk?

[peterinscotland]

What would happen if I mixed equal quantities of white Sandtex Ultra Smooth Masonry Paint (Microseal) with a cream coloured Dulux Smooth Silk?

I have a good quantity of both and wondered whether it might save me buying new masonry paint. Would it start peeling off the wall within a year or would it still be likely to give several years' protection?

Regards

Peter

Your barking mad mate, what do you think will happen when you mix an interior paint with an exterior paint?

Mould growth, no resistance to the weather, peeling, flaking, discolouration and quite possibly the world will fall off its axis and we will all die.

Thank you for your comprehensive reply as to why this would be a DIYnot!
