i am looking for a waterproof foam to seal a gap between a brick wall and plastic in a hard to reach area?
Answers:
Most DIY outlets have a polystyrene foam in an aerosol can. They have a flexible plastic spout to get into places. You will have a few minutes to push it in with a spatula or similar and it is best to apply in several goes to build up a layer. Its permanent and waterproof. Good luck.

i had a problem with my skylight leaking in my roof, i didn't have the proper stuff to use for it, so i used bathtub caulk- it sticks to most anything and is waterproof and not very expensive.
spray foam, very easy to use spray it in the gap ,watch it expand, cut off the excess, all DIY shops sell it
no problem
i use gap filing expanding foam in those tight jobs, it seals and there is also heat/flame resistant...
don't have the name here, i will mail to you tomorrow
there is one called no more big gaps .its waterproof and can be sanded and painted.its simple to use and can be got at any diy store.
Use the spray foam. It will expand greatly overnight. Allow to dry a few days then "trim" it flush.
was it a new build , if so get builders to sort it
I've used "Great Stuff" to seal cracks between the railroad ties in my retaining wall. It has worked well but the instructions on the can warn that it is subject to attack from UV light.
I spray painted all of mine black. it has been in place about 8 years,.
