Pergola / August 27, 2018 / JulietteHughes
This will cause your beautiful Pergolas lines to be ruined. Moisture Issue: Less expensive materials often last longer in dry climates while they may weaken gradually in the moist and harsh climates. Consider the amount of moisture in your local weather and long-term decay issue. Drier gentle climate areas are easy on pergolas but the quality of wood becomes an issue whenever there is significant moisture or weather extremes. Manufacturers Warranty: Before buying an arched pergola make sure that you can get replacement parts in future years even though your pergola is custom-designed.
It gives colour to the wood and also conceals some of the natural defects and characteristics that may stand out obscuring the real beauty of the wood. Paint is also beneficial because they prevent moisture damage and rust. Acrylic paints are the best choice for painting pergolas as they provide the best protection. The durability of pergola depends on the materials chosen for its construction. As the roofs are permanently exposed to the elements of nature the paint chose may fade easily. Also materials such as fabric may fray or fade and plastic or fibreglass roofs may get warped or change colour.
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.
