Application

Plaster is preferred to use on both exterior as well as interior but stucco is the best thing to use on the exterior since it owns rough texture and is more durable for exteriors than any other type of plaster. However, exterior plaster is far more versatile than that of stucco and can be applied to arrays of smooth surfaces like drywall or concrete. To apply stucco you will need to have your exterior surfaces correctly prepared.

Installation

Stucco and plaster both require well trained and experts to install. It is usually applied over a wire lath in three layers. Wire lath is used here to provide stucco a surface where it can strongly stick to. The three coats of stucco are-

  1. Preparatory or Scratch coat
  2. Brown coat with a thick and smooth layer, and
  3. This third coat gives the stucco a distinctive appearance. 

Plaster is also applied in the same way but has comparatively a thinner coat which is also referred to as gypsum veneer that can be applied as a single coat over drywall.

And, plaster can be applied to various types of surfaces directly even if it is smooth like drywall or concrete. Plaster can also be used to create molds with inexpensive and intricate designs to add more beauty and value to your home adding up the lowest cost possible.
