Spackling is all fun and games to apply and smooth out until you have to cover the outside corners. The awkward angle, variable dry time, and extra smoothing or blending required calls for a bit more finesse and planning. However, Red Devil has got you covered with the application and prep tips below!
-First off, be prepared to make time for at least 3 layers of spackle for this area. You don’t want any show through on outside corners and the sharp angle doesn’t allow you to distribute spackle as thickly.
-Following from this, the first layer should be the heaviest as you want to cover the initial wall flaws or texture effectively before adding the blending layers. Cover all the space you need to between the corner joint and the wall using your putty knife.
-Since the the second layer and third layer is intended to deepen coverage and smooth out the spackle into the wall surface, use a larger putty knife of 10″ to apply. The wider putty knife plate will give a more widespread, polished coverage.
-After you have applied the third layer, you may switch to a 12″ or larger putty knife to smooth out any edges or mistakes.
-The position of the putty knife you use to apply the spackle should be so that one corner of the knife is aimed alongside the corner bead and the other corner is facing the drywall surface.
