What Is Stucco?

Stucco seems to be a lovely finish that is frequently seen on homes. It was a type of cement plaster. Therefore it’s solid and long-lasting. However, it has a spongy feel and is fragile when flexed. 

That is, we should avoid soaking stucco or allowing far too much water to enter the crevices. We should also avoid using excessive force. If the soil is prone to shifting, stucco homes do not settle properly.

Bear this in view, and you must exercise caution while removing dust, debris, and dirt off stucco surfaces. You can get cracks and breaks rather than dirt buildup. Then it’ll be much more of a blight!


Ways To Pressure Wash A Stucco Surface

Stucco is a sensitive material with a roughness that can be quickly harmed if pressure cleaning is done incorrectly. Cracked or peeling regions are susceptible to high-pressure cleaning, and grime can sneak into cracks the water didn’t access. Cleansing stucco needs much more simply knowing how to use PSI, but a preset of 1,600 to 2,600 PSI is usually sufficient. The plaster may be brought back to life with a bit of understanding, the correct materials, and a little elbow grease. Here are the ways on how to pressure wash a stucco surface:


#1. Examine your stucco surface

The very first step is to look for any evidence of deterioration on the stucco layer. Examine the area for any fractures, cracks, or even other holes. Moisture may seep through the gaps if you clean before even checking the stucco surface. Mold spores might begin to form as a result of this. Mold spores grow in damp environments, as many people are aware. This might result in flooding harm to the walls in certain circumstances.


#2. Fill the cracks

When you see any holes in your plaster, you must fix these before actually cleaning. Minor scratches are simple to improve on your own. Microcracks and minor chips are examples of this. We use an outdoor acrylics glue that nearly matches the stucco surface perfectly to fix minor flaws. This is available at most big home improvement outlets and neighborhood businesses. To cover the damaged or chipping area, use the sealant.


#3. Rinse the stucco surface

This is essential to polish the stucco layer after thoroughly evaluating it for cracks and mending them. You’ll have to start by rinsing the area with water. All loose dust, dirt, or residues will be removed. You may do this with an ordinary garden hose and an adapter or use a power washer. When pressure washing stucco, use a nozzle with a 30- or 45-degree angle at a pressure of no more than 1,600 PSI. Because stucco is permeable and sensitive, applying too much pressure might cause harm. The distance between the sprayer and the plaster surface must be at least twenty-four inches. Wash the surface in a steady stream at a 45 ° angle to prevent damage.


#4. Use the cleaning solution

Two liters of hot water, ½ cup Boric acid, and two teaspoons of wet dish soap are combined to form this cleaning fluid. It is indeed time to use the cleaning fluid now that you’ve got it. Use the solution at a lower setting with a 70-degree nozzle for stucco power cleaning. Keep a distance of 18–24 centimeters between the tip of the nozzle and the plaster surface.

Allow the solution to settle for 10 minutes after administering it. Make sure the solution doesn’t dry out since cleaning that off will be more difficult. Keep it wet by softly sprinkling this with water now and again.

#5. Scrub the wall

To thoroughly erase stubborn stains, you’ll need some additional Care in the shape of a paintbrush. Wash the spots off with a small brush, whether by yourself or with the assistance of a revolving brush adapter. Wash the sites in parts while applying gentle yet forceful pressure.
