I would suggest you get some thicker skin as they say as this business will get you doors slammed in your face, people yelling at you for calling them on the phone, hate mail back for sending them mailers, and much more.

But what happens is every once in a while you get a tenant that trashes all the carpet and now you have to deal with replacing it all.Its so much easier having the thicker vinyl plank so that you no longer have to deal with those kinds of turnover costs and effort.

However it is oil based and a little thicker than normal paint.

An additional note, of the three different quad-glazed windows we examined for use in renovation of our own house, they all required a minimum of 2x6 wall thickness and would probably work better in a thicker 2 x 8 stud wall.Insulated spacers in a triple glazed vinyl window (I've yet to find one with a real insulated frame) will probably give you the best performance / cost ratio.  

the first two posts are a great suggestion, just want to throw another option at you to consider, you can use a grinder with a concrete blade and use it like a sander and blend the batch into the original wall area to make the patch blend in better with the wall then use a basement paint like Drylock or a water proofing that is painted on the walls, its a little thicker then just concrete paint and will help to cover up the patched area.

I am guessing from the amount of stain on the base board and the fact you said the "floor guys" said it was thicker than normal it is excess stain. 

Was a tough phone call to make, but I guess I'll need to develop thicker skin.

Finishes can vary in the thickness of the plating... the thicker the better. 

It will go on much thicker than latex (water-based) paint.

No problems there just a bit thicker floor than usual.
