wood and concrete

I have recently added a basement to our cottage. Raise the house, pour the foundation and re-seat the house. This implies that there are U-shaped openings in the foundation walls to allow the steel beams that were supporting the house to be removed. I have put in windows and doors in those openings and I have "sealed" the top of the doors and windows with wood (like would be done on a wooden wall). In the exterior, I have attached roofing paper as a water proofing media and it has worked well over the winter and spring. Now I want to make this permanent. How? Can I stucco on the concrete walls and overlap on the roofing paper? What about expansion? Is there anything else I can put on that will make it look uniform? Remember that I am in Canada and we have +30C in the summer and -30C in the winter. Also this is a 3 season cottage. No Heating in the winter.

Thanks.

 

What you need is a bitimous clay product. You can get it in panel form or in paint. Ugldrylock is a good paint to use as it seals your foundation. You can chose to use water based or oil based. How they differ I am unsure. ~ Rob

 

Welcome to the forums Mike!

Drylok is a good water proofing block fill type primer but if I understand correctly it's not what you want. It would hamper efforts to stucco over it. I believe the oil base drylok is slightly better than the latex version but it's extreme odor makes it a no brainer to choose the latex.

You should be able to stucco over the raw masonry but you would need to install some lath over the tar paper in order to stucco over it.... but I'm not a mason - if one of the masons don't respond here, try reposting in the brick, masonry and concrete section of the forums.

 

I don't have an answer for you, but I would like to say good job. That's quite a feat you've accomplished!
