Ask the pros at your home improvement store for advice. They have the products and know- how to fix them right. Photos always help!

Appliance epoxy by rustoleum is pretty water proof.they also sell bathtub paint and marine paint or boat paint at home depote or whichever like store you shop at. The bathtub repair paint however is very expensive usually like almost $30 a can where is the appliance epoxy is 399 I believe last time I bought some say it works almost as well pretty much the same product very simular for a 10th of the price.

I like marine paint for exterior stuff myself. Rustoleum sells it in the quart. They also have a newer spray called Never Wet you can put on anything you want to repel water.

Hi Mike. Hope this is the answer you are looking for. Peeling - Window Sills and Frames - Sherwin-Williams

For exteriors, use SWP® Gloss Oil Based Enamel or SuperPaint® Exterior Latex High Gloss Enamel for surfaces exposed to standing snow and rain to help keep water from entering the wood. On new wood, use an oil-based primer and two topcoats of exterior gloss.

Hi Mike,

Be sure to clean and sand the areas to be painted, then use a marine paint, Rustoleum has a product that works very well, you can get it a diy stores.

Hi Mike - We have these kinds of windows/frames in our bathroom and it gets a lot of moisture. We used deck paint and it's been working great. Hope this helps! Holly

Most of the time when paint fails prematurely, you need to look at the surface first. Latex holds up very well to moisture from above since it creates a durable barrier, but moisture from under the paint will cause peeling almost immediately. This could be caused from moisture wicking through the wood from a leak, or wood that is new and hasn't seasoned thoroughly, or due to poor bonding.

The first two issues require investigation, but a poor bond simply means surface prep. Was the surface clean and smooth? Did you use a high quality primer and allow to dry thoroughly prior to painting? The failure to apply primer to raw wood is one of the most common causes of premature paint failure. Many paints advertise "paint + primer" but this is NOT a substitute for a surface prep primer such as Kilz.

I would prime first and use latex paint. It could be your top coat, make sure the top coat you used is not water based.

Try RustOleum enamel paint. I used on a porch rocket last year and it held up great. Started doing windows this year. So far, so good. No blistering or peeling.
