Painting your home can seem like an overwhelming task due to the many obstacles and problems that may arise. Before you begin painting you will need to clean and prepare the surface of your home or the new paint may not be applied to your home properly.
It will also be critical that you choose the right kind of paint to use. In general the best time of the year to paint the outside of your home is during the late spring and early fall.
During these times of the year, it is generally sunny and warm. This allows the paint to dry rapidly with no interference from rain and other things that could alter your paint job.
The sun is also less intense than it would be during the summer, which is better both for the painter and for the maintaining the true color of the paint. As you prepare your home for a new paint job you may notice that there are several problems that have arisen with the old paint job that you will need to repair before you apply the new paint.
One of these potential problems would be the peeling of the old paint. Peeling occurs when the paint was applied to wet wood.
It can also be caused by the moisture in the home making its way out through the wood. The best way to deal with this problem is to install some exhaust fans to allow the moisture to escape in other ways.
However, if these do not work or if the peeling continues, you may want to consider using latex primer and latex paint. Latex primers and paints allow most of the moisture to continue working its way out through the paint instead of blocking its passage.
With normal paints, the moisture builds up under the paint forcing it away from the wood. By allowing the moisture to escape, the paint will not be forced to separate from the wood.
However, moisture is only one cause of peeling. Dirty and glossy surfaces on paint can also be the cause of peeling.
If you find areas of your home are peeling, you must scrap the loose flakes off and sand the surface until it is smooth before you can start repainting your home. It is likely that some of the primer will be scraped off during this process as well.
The areas in which this happens will need to be re-primed before they can be repainted. Wire brushes can be a great tool for removing peeling paint from a larger area.
Another problem that may arise in your old paint is called alligatoring. Alligatoring is when the original paint shrinks into small patches leaving the original surface susceptible to the outside elements.
This problem results from the top coat of paint not adhering to the primer below. It is possible that the two paints were non-compatible or that the second layer of paint was applied while the first was still wet.
As with peeling paint, you will need to scrape of this paint and sand the wall down before you can apply a new coat of paint. Be sure to re-prime the wall in the areas that are bare.
Another problem that may arise in your old paint is called blistering. Blistering is when the paint formed a bubble due to moisture or simply improper painting technique.
Again, you will need to scrape these blisters off, sand, and re-prime the area in order to prepare the area for new paint. In order to fix the source of the problem you will want to examine the area.
If you can see dry wood beneath the blisters when you scrape them off, you will know that the problem is due to moisture. However, if you find a solvent behind the blister, you will know that the blisters were caused by painting with an oil-based or alkyd-based paint in weather that was too warm.
The extreme heat caused the outside layer of the paint to form a skin, under which the solvent was trapped. This is the primary reason for why the best seasons to paint are late spring and early fall.
Another problem that may have occurred in the old layer of paint includes wrinkling. The wrinkling occurred when the new paint was applied and it ran and sagged into a series of slack, skin-like droops.
Wrinkling can also occur when you use too much paint or when painting during cold weather. Before you can re-paint you will need to sand the wrinkles.
