How to plaster a wall?

Plastering is one of the final steps in finishing an interior or exterior wall. While applying plaster is a highly technical process that is usually best left to professionals, any homeowner can do it themselves provided they follow a few key guidelines. First, start with a batch of thick, freshly-mixed plaster. Spread the plaster onto a clean wall with a trowel, then use a handheld float to smooth it from corner to corner. After you’ve worked out lumps and inconsistencies, the wall will be ready for paint or wallpaper.
