Exterior Painting in Potomac: What We Do Differently

Power washing in Bethesda

#1.  Proper Power Washing Techniques

When power washing or pressure washing your exterior, we let the chemicals do the work, not high pressure.  We leave the high pressure on Time Share salespeople.

We use the least amount of chemicals that kill mildew and get rid of dirt and pollen collected in the home.

Our cleaning products will not harm your plants or flowers!

FYI – We insist that the chemical stay on for 15 minutes.   

That’s the amount of time necessary to kill the mold spores. 

If not, the mildew will grow back much faster.

#2. The Moisture Meter

It doesn’t matter how much prep or the type of primer and paint you apply; the paint will peel if the wood is damp. 

Moisture is the number one reason paint peels.

The moisture content needs to be under 16% to be considered safe for painting.

#3.  Choosing the Right Primer

There is no “one size fits all” for exterior primers.  Whether you are painting Georgia Pine or pine from Canada, it’s not the same primer.   

What happens if you choose the wrong primer?  The paint will peel.  


Because the wood, primer, and top coat of paint are not expanding and contracting at the same rate. 

With the sharp changing seasons of Potomac, it is essential to have all three surfaces expanding and contracting at the same rate.

When choosing Klappenberger & Son, we can advise you on which primer will work best with your surface. 

#4.  Exterior Painting in Potomac:  One Coat or Two?

Besides applying two coats satisfies the warranty, it also extends the paint job’s life for years.

For example, the picture on the right clearly shows where someone brushed the edges and seams and then painted the exterior wall with a roller. 

The areas that received two coats have significantly more paint left.

Applying a second coat of paint usually adds about 30-35% to the total cost of the job.  Considering it can extend the paint job’s life by five years, it is a wise investment.

                               #5 Proper Weather Conditions

Everyone knows you can not paint in the rain, right?  How about the temperature?  Most manufacturers like the temperature to be lower than 90 degrees and above the mid-’30s for at least 24 hours.  If paint freezes before it fully dry, it can lose its ability to cure fully.  

Also, if it rains before the paint cures, water can penetrate through the paint, causing bubbles. 

Therefore it is best not to paint when the chance of rain is above 40% for the next 24 hours.
