why do you want to paint it, sand it back and stain and varnish it.

A lot of insurance policies do not allow for candle burning--huge liability, and after having to repaint a place after soot and wax stained the wall (and the carpet) and several burns in the carpet, that kind of hit it home.

I am rehabbing a house with pet urine stains throughout the upstairs subfloor.

We have hard water in our area and hard water mineral stains in the toilets and sinks are common.

., if they stain, you can just lightly sand them out and reseal to a new looking counter.My brain is fried at this point and any and all thoughts are appreciated.

Use tans, darker grout as posible, use grout sealer to prevent stains, and use PORCELAIN tile just make sure your patient or keep eyes open for sales on it and store it away when under 2 an sf.

depends on the income class...i do lower to median income tenants..no ceiling fans, no icemakers, no dishwashers, no garbage disposals, no carpet..anything that's not required by minimum housing code is something that they can braek and will expect you to fix...carpet will need to be changed between tenants...i paint my hardwood floors brown instad of sanding and staining bc most tenatns will put rugs down on them anyawys...i try to use commerical grade VCT tiles as mucha s possible.you can buff them and clean them up pretty easily...just think durability...you want stuff that will last and look decent in 5 years still...

i'd inspect the carpets to make sure the stains are not more then just normal ware and tear.

After we tossed the garbage and ripped up the carpet and linoleum this is what we have: both bedrooms have water stained hardwood floors, bathroom and halway floor rotted, mold around bedroom windows, 6 of 8 windows are broken/damaged, duct work for HVAC is damaged.  

I used to use epoxy but fusion is also very stain resistant and acrylic so easy to use....not cement based but it looks cement based.
