Old porch repair

Hello

I live in a 90+ year old fieldstone house with a roofed, wooden tongue & groove porch that needs painted badly. My problem is that all around the perimeter of the porch floor there is a gap (up to 1/2" wide) between the ends of the porch boards and the fieldstone walls. When blowing rain or snow lands on the porch, it melts into the basement room below it.

I previously tried caulking that gap with latex putty, 100% silicon putty and spray foam, but after a winter, those products remain stuck to the fieldstone BUT loose from the wooden porch boards, thus creating more openings for leaks. Im looking for a flexible product that can fill that gap and also "give" as the climate goes from one extreme to another.

Can anyone suggest a product and/or procedure I can use? Ive sc****d, wire brushed all the porch boards and cleaned up all the failed caulk and am waiting to give it a good paint job that will last.

Thanks kindly
Dee

Sounds like what you need is flashing and a porch deck that slopes away from the house. Also check the grade under the porch to make sure everything slopes away.
There's nothing I know of that will do what you are asking. I doubt the gap is the main problem. A tongue & groove deck will not keep out water completely.
It's pretty hard to keep water from getting through an old field stone foundation especially if water is collecting against the wall. Check that any downspouts are led away from the building.

Thanks kindly for your reply, but I think you may have misunderstood some of what I said.

The house, as well as the short walls around the porch (balastrades?), are fieldstone and there is no cut out at the floor level for water to run thru those fieldstone porch walls if the porch boards were sloped as you suggested..................... unless you can slope the entire floor in two different directions (across and to the front) to make the water eventually run across the porch and then down the porch steps (which are located in the front and on the end of the porch, which is actually in the center of the front of my house)!

I don't have any leaking between the tongue & groove boards. Im sure many good coats of oil base paint over the years is to thank for that. It only leaks around the edges of the porch where each board meets that fieldstone. My issue is finding something that will bond to the boards and the fieldstone.

My foundation is cement block. No leaks there either.

I thought of using backer rod stuffed into the gaps and then spraying it with that black rubbery substance in a spray can.

All the putty and silicone you put probably failed because 1/2" is a wide gap.

Can you attach a photo? try loading a photo on a site like photobucket, then give us the link.

The best concept is to get rid of the water safely rather than in having it collect where a problem could (and probably will) arise later on because of that. Do the pics, it will greatly help us be able to help you. Some of the gapped area close-in and some from a distance so we can see and understand the situation as a whole including where the water will have to drain to.
