Cuprinol Fence Sprayer - alternative advice sought
 

Just got one of these for Xmas, and it works a treat.

OK it says do not use it with other products, and I understand
creosote causes a problem with plastics.

But can I use this sprayer to spray my outside wall with 'exterior
emulsion' ??? Or would it be just to thick.

Or any advice on what product would go throu it, that could go on my
walls.

TIA
