What happens here

Similar to the staple test, the creator attempts to hang his full body weight from the house wrap secured with cap nails. Initially, it holds for a moment, but then the house wrap tears, and he falls. This is also marked as a 'Fail'.

Goal: Assess the pull-out strength and integrity of cap-nailed house wrap under stress.

Tools and materials

  • Heavy Equipment — To provide an elevated anchor point for the wooden board
  • Wooden Board — The test apparatus for the pull test

What they say

Hide

If you go heavy on the staples compared to using cap nails, you're probably the same for pullout, but cap nails are supposed to be better for water. I don't like cap nails, but I know some places require them. That hurts.
