1.) Crack difficulty: Easy
A crack can run just a short length on the beam or the entire length of the beam. Both are easily fixed.
2.) Tools Needed:
3.) Flip the beam over. Wipe the inside of the beam with a clean rag. Remove any dust, dirt or debris that would prevent a good bond with glue.
4.) Apply a generous amount of the PL construction adhesive, Gorilla glue or liquid nails (use as directed) to the inside of the beam on the reverse side of the crack.
5.) Spread the glue with the spackle knife to make about an 1/8" layer of glue on the inside surface of the beam.
6.) Place the splint material into the glue. Press it firmly with a slight twisting motion to insure full contact with glue to both surfaces.
7.) Hint: Make sure the paint stirrers or tongue depressors that you use as splint material are running perpendicular to the crack.
8.) Make sure before the glue sets that the crack is closed tight and not pushed open.
9.) Leave beam untouched for 24 hours to allow the glue to fully cure.
