How to Skim Coat with a Roller for Beginners?
An uneven and damaged wall can easily be recovered through the skim coating process. This process uses drywall mud to create a thin coat on wooden, brick, masonry, or metallic surface. A Skim coat can be applied using hand, paint roller, or spray rig. Then by a drywall knife, it is smoothed out.
For beginners, the skim coating needs to apply using a paint roller because it is easy to use and lets you finish a project quickly. Use of hands is not recommended since the process will become time-consuming. In contrast, a spray rig is suitable for professionals.

Using an electric drill and mud puddle, make a mixture of drywall mud in a large container. Adding water is mandatory to mix the powdered form and then stir it.

Continue mixing water into the drywall mud until it becomes thin enough to be used using a roller. When the mixture gets a milkshake consistency, stop mixing more water.
Step 03: Pour the thinned drywall mud into a container
Take a paint tray and pour down the thinned drywall mud in it. Use a roller with a ½” nap cover to roll 3’ X 4’ (WXH) sections. Ensure doing this 1 section at a time. This will help you in smoothening out the surface before the coat dries.
Step 04: Apply the drywall mud
Firmly hold a drywall knife and use it to apply the joint compound over the wall. Apply an adequate amount of joint compound over the wall, and light coverage of the wall is undeniable. Sand the wall if required using fine-grit sandpaper.
Step 05: Continue the process and let it dry
Don’t rush when moving to the next section. Heavy lines will not be visible when you overlap slightly. Continue the same process until you finish one coat of drywall mud. 2/3 coats may require depending on the wall’s damage. Before you apply paint on the surface, ensure proper drying of the drywall mud.
