Adhesive and Sealant Applications & Tools

   Why do people use their fingers to tool a joint?  Professionals use tooling knives or spatulas to smooth sealants after dispensing.  And they don't do it just to make the joint look good.
   Tooling is a critical step in the sealing of a joint.  Sealant manufacturers require that their products be pressed down into the void to ensure adhesion on both side and to smooth out all gaps and bumps from the surface..  Only after tooling is complete do you have an effective weatherseal: Air, Vapor and Water.
   You can't accomplish all that with your finger!
