We purchased a older house and all the paint on the walls, trims, and doors were in oil. I had no experience with paint at all. At this paint store, the lady we very patient. She took her time out to educate me and gave me advice on my huge project. I had to re-paint the whole house. She taught me about using primers. How to test paint...if it's oil or water based. How much paint is need for how much space. She even gave me same great advice on colour selections and what brand to use. Now that I am done with my project, I think back and realized I could of never done it without the great service Markham 2000 has provide me. They thaught me everything I know.
