I believe that careful prep work pays off. I make sure that I mask my areas carefully before I start any paint job.
Despite my best efforts, I will sometimes get a little bleed-over. This problem can be difficult when the paint is on a newly finished staircase. One way to regain a nice sharp edge is shown below:
- A rag is placed over a putty knife.
- A little Goo Gone is dripped on the rag.
- The edge is carefully scrapped.
- A new sharp edge is formed!
