Pergola / August 27, 2018 / JulietteHughes
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 choice of materials to cover or roof the pergola depends on the buyers instincts as to the choices for durability permanency and availability. In tropical Australia zinc-galvanized corrugated sheets do not reflect infrared or ultraviolet much. White roofs reflect better. White or soft shades are better colors for a cool roof. As the Earth seeks to get greener the best choice of course is to enjoy traditional open roofed pergolas. Painting your Pergola Anything that is exposed to the harsh elements of nature will eventually need protection. Painting is one of the best ways to provide this protection.
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.
