In my quest to find something easy to work in but showerproof I've been wondering if it is possible to waterproof a jumper. I have a couple of poly-cotton sweatshirts that are a very tight weave and I wondered if they're take a wash in or spray on waterproof? If so would it actually waterproof them at all? I'm not expecting downpour proof but resistant to light drizzle.

A compromise garment will always be a compromise.
If the coating process doesn't work well, then what?
Buy a waterproof shell. It doesn't have to come with bragging rights.
Maybe buttons/snaps/buckles to open the front that you can't do with a jumper.
I buy the same rain suits that the Public Works guys wear around the village on rainy days.
Duct Tape for patching.

There is a water repellent treatment for wool that might work upto a point and of course there are the various DWRs.. I don't think a sweat shirt can be waterproofed but just made somewhat repellent.
Everything's a compromise isn't it? A waterproof shell is more bulky than a jumper for working in, you get much hotter in the summer and it catches on everything.
I don't know what happens if the coating process doesn't work, hence the question. I assume it'll just be less waterproof rather than damage the item but if I pick up a second hand one to experiment on it'll only waste a couple of pounds.
I do find the poly cotton to be slightly resistant but looking to increase the resistance.

The easiest way to test is take a DWR spray and see what happens. As a first guess it helps but it is not going to be a raincoat.
The main problem is that they are meant to absorb moisture. You might have success with one of those with a smooth reverse side but if it's a fuzzy one I think it might be hard to stop it wicking water inwards. Maybe try a treatment that can be removed by washing it?
Yes, in my opinion the idea is nonsense.
It's possible to waterproof cotton tent sheets, that was a military standard in both world wars in all armies, and this is in use until now.
A jacket made from such a fabric works well for a few minutes of spray. But there isn't really a reason to do it, because ultra light rain jackets work better and are very cheap.

Don't hold back.
I've already explained why I don't want to use a waterproof jacket. I wouldn't say the suggestion is nonsense but I find them too bulky and hot at this time of year to work in. I put the one I have on and removed in if a couple of minutes work as it cought on several brambles and I began to steam up like a plum pudding.
Now, what SaraR says makes sense. The jumper I have in mind is sold as a sweatshirt but I think that's just the name and it's not really designed to wick moisture. It does have a felty inside so a spray on waterproofing seems the way to go. I have a bottle laying about so no harm in trying.
I've worn a few riding hoodies for skiing when it's been hotter and no snow forecast. They all have a DWR coating and range from thick hoodie into full soft shell, seem fairly resistant to showers etc. latest one from planks is ... if that helps at all. Not had a cotton or wool blended one they all seem to be polyester.

The result will be that it absorbs less water and that makes it somewhat warmer, at least when the rain stops (dries faster). Also less weight to carry around.
A spray-on waterprofing on the allready treated shirt will give some more effect but on a fabrik of that type it is something to try but not put that much hope on a big different.
