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. 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. 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. Application of a water repellent preservative with fungicide is an excellent idea before painting because it prevents absorption of water by wood which may cause decay. Here are the steps to paint a Pergola: Remove the furniture and any decorations you may already have. If there are growing and climbing vines, protect them with plastic sheets and tie them up so that they will not be in the way. Also remember to water them if the painting takes more than a few days. Wear a mask, a head cover and protect your eyes with safety glasses. Also wear an apron or old clothes to protect from paint splashes. 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.
Causes of Discoloration of Pergola roofs Over time, Pergola roofs may get discoloration due to dirt, fungus, mildew or moisture. Also, any iron fittings may rust and cause red stains which may react with other pigments or stains. To prevent this, stainless steel nails may be used and a constant vigil kept to encourage the Pergola to stay dry. A commercial mildew remover or other multi-purpose cleaners and help keep the roof spotless. Stains that are caused by the reaction of water deposits on the wood may also be removed by washing it with cleaners. Chalking is another form of discoloration which is caused by weathering of paint or disintegrating of pigment particles, which appear as a powder. Restoration painting necessitates cleaning by paint strippers, bleachers and oxalic acid based solvents to remove stains.
