Using sand paper remove all paint until the surface is completely prepared. Apply a water-repellent and fungicide if necessary. Using a paint-sprayer spread evenly from the farthest end to the back. High Volume Low Pressure (HVLP) sprayer is more efficient and smooth. Use a paint roller to get a smooth finish. Give a light coating on the roof of the Pergola. Fill in the gaps and allow the paint to dry for up to four hours. Apply a second coat of paint on the roof of the pergola. Allow the paint to dry overnight.

So while buying wooden pergolas ask their manufacturers if they are partially notched or fully notched. Buyers should be aware that notching creates interlocking joints and this fortifies the structure. Also notching insures that all your timbers stay straight and true over the decades because they cannot move. Most manufacturers skimp on notching partially or completely to reduce their construction costs and will tell you that hardware will take care of the issue. It does not. If just one of your Pergolas timbers has hidden stresses in it (quite common) as it weathers over the years it will turn twist or sag.
The pergola has evolved from its famous brick and stone posts of 19th and 20th century to modern wood designs of the 21st century. The idea of modern wood design of pergolas is its affordability and increasing popularity in modern garden designs. But because brick and stone are weather resistant hardwoods such as Western Redcedar and Coast Redwood are used instead to match with the pergolas made of brick and stone. As the normal use of a pergola is being an arbor for vines some architects introduced pergolas as a structure made as a protection from rain or direct sunlight.
