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.
Depending on the type of fabric used these pergolas may avoid the transmission of heat which could cause fading or damages to the roof. A tough and durable fabric that may usually be used in the making of the sails of a boat can also be used to filter ultraviolet rays and other harmful natural elements such as sunlight and heavy rain so that people can enjoy their investment for a long time.
