It is the drying time between coats that takes so much time.

You don't need multiple coats and it can be painted right away.

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.

After it has dried good do 3 coats of poly, make sure to use the stuff specifically for floors.  

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.  

my typical cleaning procedure includs steam carpet clean and professional cleaning of the interiors, fresh coat of paint and thought that should cover it all. 

But I see many people online and more than a few in real life who are paying stupid amounts of money for "mentoring" from people teaching basic stuff with a top-coat of unadulterated BS.  

I have been happy with the Cabot products at Lowes...Read the instructions on the can, if I remember correctly, you can only recoat within an hour or so because it contains teflon and so will repel the second coat if fully cured.

I believe the LR needs a door that shuts the LR off, there must be a closet (coat closet will technically be sufficient) and an egress window/door, which all LR should have.
