Waterproofing a Painted Surface
I need some help! I bought a house that has an older wooden garage that has been painted a few times. When it rains, the water seems to seep all the way through the wood. When I go in the garage and put my hand to the inside wall, it's very damp. Are there any ways I can waterproof this wood without scraping all the paint off the garage? The inside of the garage is not painted or sealed.

Do you know what type of paint is on the wall already? There are some specialty products (like spray paint that can be used as a super primer on oil paints) that might be helpful. You also need to be careful that you dont accidentally trap moisture in the walls.

I'm not sure about the first coat, but there is a coat of Glidden Speed-Coat and the latest coat was a Sears Weatherbeater Exterior.

The paint itself (a quality one anyway) will provide water resistance and protection to the wood

You have to scrape the loose any peeling or badly adhering paint off before re-painting, and primer any bare wood areas

If it still leaks with a quality coat of paint on it, then the leaks are due to some thing else, like needing caulk in the cracks or roofing issues or something

Have you checked the roof? If the siding was installed correctly, whether painted or not, the inside walls should not being be getting that wet. You may have other issues...
