I have an extension to my house with a deck on top that acts as a roof. But the deck does not slope away from the house, so every time it rains, the deck fills with a puddle in its center. I have heard that I can build a slope on the deck using thin-set mortar and acrylic milk. Is this possible?

I have been removing old tiling from the concrete floor in the basement of my 60-year-old house. Underneath the tiles is an old layer of paint. The paint is so old that where it is not still adhering to the floor, it has turned into a powdery substance. Do I have to remove the paint on the floor before I paint again?

I have some wrought iron patio chairs. What is the easiest way to remove the paint and refinish them?
