The present invention relates generally to wall repair compounds such as joint compounds, spackling compounds, and the like used to repair imperfections in walls or fill joints between adjacent wallboard panels. Particularly, the present invention relates to such a wall repair compound comprising a dust reduction additive that reduces the quantity of airborne dust generated when the hardened compound is sanded and also exhibits improved adhesive properties. The dust reduction additive also imparts adhesion to the wall repair compounds to which it is added, for example to a joint compound. The dust reduction additive comprises micro-crystalline wax or micro-crystalline wax emulsion.
