Looking at a home that I’m interested in but it has plaster walls that are cracked everywhere (just the top coat).  

There are protective electrical coatings which exclude the air and prevent corrosion, that is what the utilities use to ensure their lines are protected.

My property manager is quoting 4k for one coat. 

Hello dear fellow investors,I've just bought an easy fixer upper that only needs cosmetic improvements (a fresh coat of paint, new flooring, tiles in the kitchen and bathroom, clean the pool).

Rustoleum has a product for coating tile that you could try.

I could get the 12mm laminate for 2.82 on sale, but I feel like it’s so much more durable and thicker then the Lpv I’m honestly shocked that the Lpv 22mm holds up better holding the 2 samples you wouldn’t think so

Should I apply another coat of stain? 

. ; 5) Pets may leave gauges in the flooring from nails; 6) Compared to LVP they do not add any more $ in value LVP is nice because: 1) It's less expensive and easy to install; 2) Is water proof and scratch proof; 3) The thicker wear layered planks i.e. 12mil or higher will last longer than hardwoods unscathed; 4) its pet proof; 5) In the off chance that many years down the line there is wear on the floor, you can replace them still for cheaper than you can refinish hardwood flooring, and its a new floor again. 

@Tyler White quartz often comes in 3 mm, so look for other product lines if you want thicker.

I saw one repository list where somebody had written with one, an amount next to the land, which I presumed is how much it actually coated, and that anyone could go and purchase it for said/written amount as I mentioned...
