Not necessarily.  Many contractors will encourage you to replace all the siding on the house.  You can however, replace individual pieces of siding or sections of siding without having to replace all of it.

Usually the lower siding boards get the most weather.  They are exposed to more rain and more sun than the siding boards up closer to, and shielded from the soffits or overhangs.  If a siding board is swollen or soft then it should be replaced.  The first indicator of the siding going bad is on the chimney.  Because the chimney receives very little heat from inside the house it has a tendency to have more moisture inside and therefore weathers the siding more quickly.  If the chimney siding starts to go bad it may be only the upper portion of the chimney, above the roofline, that shows weak first in that section and can be replaced.  It is not uncommon to replace all the siding boards on the chimney with Hardy Siding.  When you look at the siding on the house you need to look underneath the bottom drip edge or weather bead of the siding board.  If looking at the bottom you begin to see fractures or cracks in the bottom of the edge then you have to check see if the board is soft.  This is one of the main problems that Georgia-Pacific and Louisiana-Pacific siding has.  Due to the fractures in the bottom edge of the siding it will absorb rain or beads of water that hang on the bottom drip edge of the siding.  That will cause the siding to continue to swell and rot.  If the siding has these fractures and is still solid you can use a thick primer or even a caulk that is wiped off to help fill these small fractures so that it will absorb less moisture.  This process extends the life of the siding.  If there are no fractures, no soft siding and no swelling there is no reason to replace the Georgia-Pacific and Louisiana-Pacific siding.

Another problem that occurs but less frequently is that Georgia-Pacific and Louisiana-Pacific siding appeared to have nail heads that were sunk too deeply by the nail gun of the contractor.  That does not happen occasionally but generally you observe that the nails have remained in position and that because the siding has swollen at the bottom edge, there are holes where the nail head was.  This is easy to remedy if the siding has not swollen too much by simply filling the nail head with caulk and wiping off excess caulk.

Another less frequent problem with the Georgia-Pacific and Louisiana-Pacific siding was that it would sometimes spall of the surface of the siding board.  This appears as if small chips of the siding has occurred.  Again this problem can be solved by sanding lightly by hand and then using a good acrylic primer.  This is not a long-term solution but generally will get you through another painting season.

You can do a lot of single boards or sections of the house without having to replace all the siding.  If approximately 30% of the boards need replacement then it may be worth considering full replacement at this point.  The siding boards can be replaced with Hardy Siding.  If you have textured siding, Hardy siding has a similar texture.  It’s not exact but is in most cases difficult to discern the difference from a short distance that there is a slight difference in the texture pattern and also the bottom weather bead edge.  

Why should I add mildewcide to my paint?

Yes, there is a mildewcide that is exceptional and gives years of resistance to mildew.

There is a vast difference in mildewcides as far as their effectiveness.

Quality paint comes from the factory with 1% mildewcide.  That is helpful and usually gets 4 years or so before you start to see mildew buildup on your home

In government testing of mildewcides based on a good, fair, poor, rating there is only one mildewcide that received a good rating.  MX3 made by the M1 Company is the best out there.  It is the only one that scored a good rating.  All the rest scored fair or poor.  This product is also environmentally friendly.

We add MX3 to every gallon of exterior paint we use and see most of all our clients’ home mildew free or only a very light build up after eight years.

The advantage of using this mildewcide for the homeowner is it is unlikely that they will have to pressure wash the house between paintings.  This, of course, saves the cost of pressure washing the house.

How can I get rid of old paint?

There are two fairly easy ways to dispose of old paint cans.  It’s not too difficult but takes a few minutes to do.

If your city does not have a day they set aside for disposal of paint products then there is a good solution and you don’t have to wait for the yearly date.

If you will open the can, usually it’s a partial gallon of paint, add kitty litter and stir the kitty litter into the paint, leave the top off, and let it dry.  Don’t skimp on the amount of kitty litter because the paint must be dry solid.  Replace the lid and set out for your garbage.  In most cities this is a legal and appropriate way to dispose of old paint.

 

The second method is to spread out newspapers on your pine straw areas and pour the paint out on the newspaper and let it dry.  When it’s finished drying, simply roll up the newspaper and put out for your garbage man.  

If the paint is still good, do not dispose of it, it can be used as touchup paint.

If you are using latex acrylic paint you need at least two hours of sun for paint to dry before the rain comes.  If heavy rain is forecast or several days of rain are coming in the next few days, you will need about six hours of good sun to dry the paint thoroughly enough to not be affected.  Paint will dry to the touch in one hour or so depending on the heat of the day.  It takes about five days of normal weather for paint to dry all the way through and for the paint film to reach its maximum hardness and durability.

If it rains before the paint surfaces dry the rain will wash some of the paint off that were painted last.  This is rarely a problem because the surfaces, when dry the next day, can just be repainted.

Exceptions to this rule would be if you are using oil base pant.  Oil base takes longer to dry and therefore rain should not be in the forecast for about 24 hours.  Oil base paint is not recommended on exterior surfaces in southern climates.  The oil base paint weathers very quickly in a sunny climate and loses its gloss and does not have the flexibility it needs to endure the hot sun.  It will generally crack and peel much more readily then acrylic paint.  It is also begins to break down in three or four years and becomes very susceptible to mildew which feeds on the resins in the oil base paint.  It is subject to rapid color fade and chalking.

How soon can you paint a house after the rain?

Generally if the surface is dry to the touch you can paint the surface if using acrylic paint.  The acrylic paint allows small amounts of moisture to pass through the coating from the surface to the air.  It is a rare occurrence for acrylic paint to bubble due to moisture.

If using oil base, which is not recommended, you must have a perfectly dry surface which may take one or two good days of drying weather.
