Removing Pad Staples, Preserving Chalk Lines and Other Things You Always Wanted to Know But Never Asked
First, examine how you currently get all the staples from the pad off the floor when pulling up carpet. You might use a pair of pliers and simply pull them up. You might use a staple remover; it works faster than a pair of pliers, but it is still a lot of work. I prefer something faster and easier. After all, time is money.
Here is a suggestion to help improve the look of floor vents. Put tackless all the way around the vent. This gives a solid base for the vent covers to sit on, as well as providing a cleaner, finished look. If you are concerned about stretching over the vents, either pound the pins down or face the front and the back toward the wall.
