How do I handle a FLAT crack repair area that use a lot of epoxy?

The StitchDog™ 4000 epoxy has a low viscosity and is designed to penetrate deep into a crack line.  When you have a wide and/or deep crack that causes a lot of epoxy to leach into the substrate, you can use one of 2 techniques.


1.  After laying an initial bead of the StitchDog™ 4000 you determine that the crack will leach a lot, you can place sand or Portland cement directly into the crack line followed by another bead of the StitchDog™ 4000.  Continue to add sand if excessive leaching is still happening.


2.  After laying an initial bead of the StitchDog™ 4000 you determine that the crack will leach a lot, place a bead of StitchDog™ 4020 as close to the crack line as possible.  Work the StitchDog™ 4020 into the crack line with a putty knife then complete the repair using the StitchDog™ 4000 


Can I install an overlay or coating product over a StitchDog™ repair?

Yes!  The StitchDog™ system can be prepped for painting, polishing, overlays, plaster, brick, CMUs and other decorative coatings without any bonding concerns.  Please note the StitchDog™ epoxy needs to off-gas for 24 hours.  We recommend waiting before installing any coatings or overlay products that might be affected by the off-gassing.
