Pergola / August 24, 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.
To paint a pergola for lasting protection it is important to follow the traditional procedures such as preparing the surface which include removing old paint using sandpaper to permit absorption and applying preservative towards the end of the painting. Preparation of the surface is very important before painting as it decides how much time the effect of painting will last. Any remnants of oil or dirt on the surface of the wood should be removed thoroughly. Using sand paper with 50-60 grit create an appropriate surface for good absorption of paint. If the wood is more than two weeks old or if it had been lying outside in rain sanding brushing and cleaning becomes essential.
2. Do the pergola plans take into account the sun? Since the purpose of the pergola is to protect people under it it is crucial that you take into account the path that the sun takes when it goes over your garden. If you want it to catch the sun you will still have to take the path of the sun into account. Therefore you should only approve the location of the pergola after you have confirmed that the suns path has been analyzed. 3. What materials do the pergola designs specify? Traditionally wood is regarded to be the best material for building pergolas. The reason for this is the fact that wood pergolas turn out to be cheaper than pergolas made from other materials.
