I have never seen a cheap way to level an old floor that was inexpensive that also worked. One of your problems is that the floor is painted, so before anything will stick to it, the paint must be removed and a new profile must be created on the concrete. There are a lot of products out there with big claims, just beware. No company will warranty their product without proper surface preparation.
The best way to create a new profile is from shot blasting which is expensive. Scraping and acid etching would not open the pores of the concrete, it would more likely fill them in.
I have had more luck with using bulked-up 2 part epoxy (not epoxy paint) to level a floor. But, epoxy is expensive.
I have used epoxy-stone (GoldenLook) to level cellar floors with excellent success. However, I would assume you would be looking at an installed price of no less than $8.00/sqft.
You would be best off doing nothing instead of going with a method geared towards saving money. |
