Most likely, one of the primary goals you have for your home is to maintain the value of your investment. Exterior residential painting may well be high on the list of important things to do. If you are a do-it-yourself type person there are many steps to doing the job correctly. If you are not, you may want to hire a professional to do the job for you. Either way, the right preparation is essential.
Your primer should be of very high quality. This will hold true for both pre-painted or bare wood surfaces. The top coat will only look the way you want it to if you put a good primer in place. Depending on the type of siding and its condition, pressure washing your home is step number one. This will remove your old flaking paint and get rid of your dirt, wasps’ nests and mildew. You should then remove any remaining loose paint followed by sanding the house to prepare for the primer coat. Using a cleaning agent with bleach is a great option for removing the mildew. If you live in an area that has continual high humidity, or live near a body of water, a mildew inhibitor may well be in order. Exterior residential painting is effective only if done properly.
If there are any gaps between the siding boards or masonry, you should consider using caulk to seal the spaces. Be sure you use the correct caulking material on each surface. Be sure to check your metal areas such as gutters, flashing, etc. for peeling paint. This should be removed with strong brush or metal brush. Primers are available for metal as well as siding. Acrylic paints mildew somewhat less than oils, but still will mildew. If this is an issue at your residence be sure to use a type that will slow the development of mildew.
Masonry can present other issues. If five years old or less, it may leach through your painted coating. This can be avoided by application of muriatic acid diluted according to directions on the container. This is a very strong acid and precautions must be taken. Rubber gloves and safety glasses are a must.
Masking tape applied to light fixtures, door knobs, door bells or other immovable objects will help considerably with the cleanup. It takes a little more time, but will be worth the effort in the long run. Remember to protect shrubs, walkways and other common areas.
Using an expert exterior residential painting contractor may be the best option if you are under time or other restrictions. It is more than a one day job. Take your time. Do your prep work and remember primer must be high quality, or the topcoat will not look the way you would like it to and may ultimately peel and put you back to square one.
