Pergola / August 24, 2018 / JulietteHughes
The pergola has evolved from its famous brick and stone posts of 19th and 20th century to modern wood designs of the 21st century. The idea of modern wood design of pergolas is its affordability and increasing popularity in modern garden designs. But because brick and stone are weather resistant hardwoods such as Western Redcedar and Coast Redwood are used instead to match with the pergolas made of brick and stone. As the normal use of a pergola is being an arbor for vines some architects introduced pergolas as a structure made as a protection from rain or direct sunlight.
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.
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.
