Feather and Smooth Additional Coats

What happens here

Allow the previous coat of joint compound to dry completely (this typically takes 4-6 hours, or longer in humid conditions). Once dry, apply a second and potentially a third thin layer of joint compound using a wider taping knife, such as a 10-inch or 12-inch mud knife, or a specialized curved knife as shown. The key is to feather the edges by applying more pressure to the outer edges of the knife and gradually lifting the inner edge as you spread the compound. This technique thins the compound towards the edges, making the transition between the patch and the original wall invisible. Work meticulously to avoid creating ridges or bumps, ensuring each layer is thin and smooth.

Goal: Apply subsequent thin coats of joint compound, extending the feathered edges further out from the patch to blend it seamlessly with the existing wall texture.
