It does a good job of sealing the exterior walls of a basement when applied liberally over a sound foundation. Helps to install a gravel and drain system at the same time.

If you are wanting to use it on the inside - forget it. A product like drylok would be better. The outside is the best place to seal a foundation wall.

Too messy! and doesn't dry to a hard film like paint does, isn't a good base to apply paint to.

In addition it is a good idea after the first coat on a fresh foundation to apply at least 15# tarpaper before it tacks off and then apply another coat. The tarpaper will help keep down abrasions by rocks, etc when it is backfilled. Also, not only is it messy it smells like you are stuck in a road resurfacing nightmare forever.

The asphalt coatings do not last forever. Even the best deteriorate and become brittle after a few years, but the crital times are then behind you. Definitely do not use on the interior.

Drylok is not your only option. It is a paint-type material. Avoid the "big box" masonry paints (Behr, etc.) - they are just paints.

Thoroseal has been around a lot longer that most of us and has been used on commercial industrial and residenetial contrete repairs and waterproofing. It is a cement-based coating that is messy to apply (pancake batter consistancy on to wet wall) and very durable and effective. You can mix it from a dry form or possibly premixed (white or gray). Can apply anything to it or can texture a finish coat.

If you are finishing your basement you should be aware that the most common entry for water is the joint between the fllor and the wall. The floor shrinks and pulls away from the wall slightly. Not a big opening but enough especially if you do not have drain tile.

It is not a bad idea to open the joint slighlty and force hydraulic cement (generic item available at the bad box stores) into the opening. Just follow the instruction on the package.

One you finish your basement, you will find it almost impossible to repair any leaks, so do it before finishing when it is open.

If you go with drylok USE THE LATEX!!!! It may cost a $1 more per gallon but doesn't have the nasty odor that lingers with the oil base. Before they came out with the latex formula, I've coated basement walls with the oil base drylok and had the homeowner to cry later about how bad it stunk up the whole house.

If you are buying based on smell, there are other proven products that work well and they are not "paint".
