Paintint/sealing old concrete

I have a home built in 1920, that does have a poured concrete foundation (not cinder block). The foundation is solid, but has crumbled a little in some spots. On one wall, I wire brushed the loose material. My question is whether or not painting it with DryLok to seal it will work well? The foundation is basically dry and solid now (after correcting some bad landscaping) but does produce effluroesence. I basically just want to seal it and make it look better. I have some dampness in the summer months.

Thank You!!

Drylok may be a good solution, but It only works with bare concrete. The walls must not have ever been painted before. Of course, make sure your downspouts drain well away from the house also.

The concrete has been painted before. However, much of the old paint has blistered off, but the paint is still on mostly the upper walls. Any suggestions? I have extended the downspouts away from the house, which has helped a lot. The concrete seems very porous. I was told that concrete used to be mixed with a lot of dirt, which is why it has tended to deteriorate over the years. I think I am getting the deterioration and crumbling under control, but would just like clean it up and seal it now.

Thanks, Todd
