Effective Techniques for Pressure Washing Before Painting

Pressure washers come in various models that release the water at different levels of force.

For homeowners who want a quality and long-lasting exterior paint job, cleaning the surface first is essential. A pressure washer is the fastest and most effective way to tackle this task. However, not all pressure-washing techniques are created equal.

Here are some of the most effective pressure-washing techniques for removing surface build-up before painting:

Get the right equipment

Pressure washers come in various models that release the water at different levels of force. Gas-powered pressure washers are high-powered; using one before painting could damage the surface. To avoid this, using an electric-powered pressure washer with a maximum PSI of 1,500 is best.

Furthermore, the nozzle type plays a big role in properly getting the job done. It's best to use a wide spray nozzle rather than a narrow nozzle. This will help steer clear of damaging the surface and allow more surface area to be washed at once, letting you complete the entire job faster.

Test the pressure

Depending on the condition of the building's external finishes, having the right equipment isn't a guarantee that the pressure washer won't do some serious damage. Therefore, finding a discreet spot to test the pressure and determine whether it's too high is always best.

Start low and then incrementally ramp up until you find the ideal pressure setting that's strong enough to wash but not enough to damage.

Clean from the top down

When pressure washing an area, always start cleaning from the top. This will ensure you don't have to go back over the same area because the dirty residue has trickled down and undone the hard work already completed.

Keep a safe distance and angle

A pressure washer should never come into direct contact with the surface. This can tear the finish apart and lead to costly repair works that must be addressed before painting begins. A good rule of thumb is to stay roughly 6 inches back.

Furthermore, the angle at which the nozzle is held is equally important. When pressure washing before painting, always aim the nozzle slightly downward from a 90-degree angle. Doing so will avoid damage and stop any water, dirt, and debris from being forced into the building through openings.

If water makes its way inside, then water damage can become a real issue that could result in a costly repair job.

Turn to the pros

Each surface is unique in terms of condition and material. If homeowners are unsure what equipment and techniques are best suited for the job, it's best to turn to a pro. Contact a trusted painting specialist for expert advice on pressure washing your home before painting.
