To cope with the latest trend of home designs, homeowners would like to do a facelift on their homes. They start choosing home decors, wall paint colors, new furniture and anything they will need on their home renovation. One of the considerations that homeowners look into is exterior painting.
The process of exterior painting can be similar to interior painting, yet the former uses different types of paints. Preparing and maintaining exterior surfaces is significantly different than preparing indoor surfaces where weather damage and wear and tear is generally not a concern. Thus, exterior house painting planning needs more effort and time.
General Preparation
Before you start painting, a thorough inspection of your home is necessary to find signs of peeling, blistering or chalking. Also, check water damages that manifest as rot or discolored areas. Identify areas of mildew and mold that need to be taken care of. You must then remove lighting fixtures, decorations, shutters, mail box etc. Moreover, items that cannot be removed, such as air conditioning unit, condensing units and the like, should be covered with a canvas or cloth to avoid paint spatter and chips falling on them. Remember to turn off power supply prior to removing electrical fixtures.
It is also recommended to cover the immovable bushes with a canvas and if required, you need to pull the bushes away from the walls by tying them with a cord to avoid hassles while painting. Shades for exterior should be cautiously designated as well. They should complement the neighbors’ color scheme to give better symphony to the external environment.
Surface Preparation
Surface preparation is a very important activity that will directly affect the end result of the painting process as to exterior painting. It’s not only critical in getting good results but it actually saves time while making the painting exercise economical. Proper surface preparation can be considered as a make or break job because even the best paint will not adhere properly on the walls if they are wet, dirty or loose.
First Primer Coat
When the walls to be painted are stained, porous, has water damage or mildew, a primer coat is important. A primer is particularly useful when we are painting a dark color over a light color or vice versa. Primer also produces a smooth surface. It makes the surface less absorbent, thus increasing the spreading ability of the paint.
Putty Coat
In the case of fresh painting or walls that require total overhauling just like fresh walls, putties are generally used. They are not be used for repainting or touch up activity, however.
Second Primer Coat
Generally, repainting services require a single coat of primer. Two primer coats are required on fresh surfaces or on surfaces that need considerable leveling and removal of undulations. Attention to the application of a second primer should be that coat is applied only after the putty coat has completely dried.
Finish Coat
Commonly, two coats of finish coat are required to get the desired finish and color. It is essential that each coat must be fully dry before the application of next coat.
