Is your floor not flat? Do you only need to flatten certain trouble spots and don't need to self-level the entire floor?
Did you know that your floor is supposed to be within 1/8 inch in flatness for today's big tiles?
This video shows a technique for flattening a floor using inexpensive products available from big box home improvement stores.
And it works with both concrete and plywood subfloor.
I'm using Customtech Silk from Custom Building Products and similar products include Henry's Feather Finish available at Home Depot, Ardex Feather Finish, and Mapei Planipatch available at Lowes and Floor and Decor.
