For those that have their drywall all figured out, measured, and hung up, the next step in completing your new wall is mudding the cracks and corners, and sanding it out for a smooth finish.
When you are preparing to start mudding your drywall, you will want to make sure, first and foremost, that you have the steady hand to do it. To make it come out smooth will require a little bit of an artistic technique. If you are confident in your abilities to make it look great, then the next thing on the list are the materials.
Go to your local hardware store and pick out the joint compound. When you return with it, apply the joint compound around all of the corners of your drywall. Start with the ceiling and work your way down. Follow up all of your compound applications with a fiberglass tape over the top of them. Let that sit overnight.
While you are waiting on the compound to dry, go ahead and apply mud over all of the dimples in your drywall made from nails and screws. It often won’t take a lot of mud to patch these uneven dips in your drywall. Also, apply mud over the tape. If you take your time to smooth the mud out a little with a knife, you won’t have to sand the completed product as much after it is done drying.
The mud and compound can harden quickly. So, if they are spilled on something, take some time after finishing everything to clean it off as soon as possible. It is a lot harder to clean off after it dries. It will take two more coats of mud to go over your wall. The next coat of mud you apply should completely cover all of your tape. It is easiest to start with the ceiling and work your way down. This time, you will want to apply a generous amount of mud, at least two inches thick.
The final coat that you apply will need to be the one that you handle with the most care. This coat will need to be sanded and delicately smoothed it out for the best looking finish.
