Pergola / August 25, 2018 / JulietteHughes
Your wood choice is one of the primary factors in determining the longevity of your pergola. Thicker Structures: Thicker wood pergola structures tend to last longer. Make sure you have compared wood thickness and the quality before buying. Check the amount and quality of fasteners your set includes. An easy way to compare 2 similarly sized Pergolas is to compare shipping weight. Shipping weight is an authentic indicator of the heft of competing products. Notching: Another important point to consider is notching. Notched pergolas last for longer times and have greater wind resistance capacity.
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.
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.
