Many homes, especially older ones, have walls with uneven surfaces. The surfaces include wood panelling, brick and even horsehair plaster. Instead of ripping the whole wall down, you can paint over these surfaces using specific techniques that will give the area a brand new look for little cost. The same techniques apply whether you are painting indoors or outdoors.
Spread a tarp or paint cloth on the ground to protect the floor.
Clean the surface well with a damp paper towel or sponge. You want to remove all of the dust particles so that you have a clean surface to work on. Allow the surface to dry before you begin.
Start by painting the trim or the edges. Go slowly so that you only apply the paint where you want it to go. You can apply painter's tape first to protect the surfaces you don't want painted. It comes off easily after the paint dries.
Open the roller cover and take a few minutes to pull out any loose bits of cotton from the roller. You don't want these to end up in the coat of paint. Attach the roller cover to the roller frame.
Pour paint into the roller tray. Dip your paint roller into the paint and roll it a few times to even out the coverage of the paint.
Apply the paint to the wall in a "W" shape, making sure that you get even amount of paint coverage. Let the first coat dry according to the directions on the paint can and then apply a second coat. Fill in any missing spots. Repeat until the entire surface is painted. The roller type should allow the paint to cover all of the uneven surfaces.
