My house is now blissfully, gloriously carpet-free. However, I was faced with tack strip that appeared to have been laid by someone who went a little crazy with the nail gun. Pulling the strip up the old-fashioned way (with thin crowbar) was tearing my floor up in a big way. To compound the pain, my tack strip is old and totally dried out, so in many areas it would splinter rather than pull up. Ugh. I needed a better method, so I experimented until I came up with one!
I filed one of my metal scrapers so it would be nice and thin. Then I grabbed it, my trusty flathead screwdriver, and my hammer. Wham bam thank you ma'am the carpet strip gave up the ghost SO easily!
I carefully drive the scraper underneath the tack strip using the hammer. Try to do this near a nail so you will get the full effect.
After the scraper is fully under the tack strip (I drive it under until I can see it peeking out the other side), I piggyback the flathead screwdriver onto the scraper and drive it under, too. You can see that this basically just pops the nail right out of the floor. Success! I keep doing this until I've got a clean piece of tack strip that has just been pulled right out of my beautiful floor. Then I sweep up and I'm d-o-n-e!!
