Pressure washing is a highly effective method for cleaning brick and concrete surfaces, rejuvenating their appearance and removing stubborn stains, dirt, and grime. However, it’s essential to approach pressure washing with caution, as improper techniques can damage these porous materials. To ensure successful results and prevent potential harm, here are the dos and don’ts of pressure washing brick and concrete surfaces that we at NoFo Hydro would like to share today.
Do’s of Pressure Washing Brick & Concrete
1) Use the Right Equipment: Invest in a high-quality pressure washer with adjustable pressure settings and appropriate attachments for cleaning brick and concrete surfaces. A pressure washer with a PSI (pounds per square inch) rating of 2500 to 3000 is typically suitable for most residential cleaning tasks.
2) Start with Low Pressure: Begin pressure washing at a low pressure setting to test the surface and prevent damage. Gradually increase the pressure as needed, but avoid excessive force, especially on older or delicate surfaces.
3) Prep the Area: Remove any obstacles, debris, and loose dirt from the area to be cleaned before starting the pressure washing process. Cover nearby plants, landscaping, and delicate surfaces with plastic sheeting or tarps to protect them from overspray and potential damage.
4) Use the Right Nozzle: Select a nozzle that provides a wide spray pattern, such as a 25- or 40-degree nozzle, for cleaning brick and concrete surfaces. Avoid using narrow nozzles or turbo nozzles, as they can concentrate too much pressure in one area, leading to damage.
5) Apply Detergent: Pre-treat heavily soiled areas with a suitable detergent or cleaning solution designed for use with pressure washers. Allow the detergent to dwell on the surface for a few minutes before rinsing it off with the pressure washer.
6) Work in Sections: Divide larger areas into manageable sections and clean them one at a time, moving the pressure washer in a consistent back-and-forth or overlapping motion. This ensures thorough cleaning and prevents streaking or uneven results.
7) Maintain Proper Distance: Keep a safe distance of 6 to 12 inches between the pressure washer nozzle and the surface being cleaned. Holding the nozzle too close can cause damage, while holding it too far away may reduce cleaning effectiveness.
How Do You Pressure Wash Without Damaging Brick & Concrete?
1) Use Excessive Pressure: Avoid using maximum pressure settings, as this can cause damage to brick and concrete surfaces, including chipping, etching, and erosion of the surface material.
2) Direct Water Upward: Avoid spraying water upward or at an angle against the direction of the surface, as this can force water underneath the surface and cause damage or erosion over time.
3) Neglect Protective Gear: Always wear appropriate safety gear, including safety goggles, gloves, and closed-toe shoes, when operating a pressure washer to protect yourself from flying debris and splashback.
4) Pressure Wash Unsealed Surfaces: Avoid pressure washing unsealed or damaged brick and concrete surfaces, as water penetration can worsen existing issues and lead to further damage.
5) Ignore Joint Damage: Pay attention to mortar joints between bricks or concrete pavers. Avoid directing the pressure washer nozzle directly at mortar joints, as excessive pressure can dislodge or damage the mortar, leading to structural issues.
6) Overlook Drying Time: Allow adequate drying time for the cleaned surfaces before applying sealant or paint. Moisture trapped beneath the surface can interfere with adhesion and lead to premature failure of coatings.
7) Rush the Process: Take your time and work methodically when pressure washing brick and concrete surfaces. Rushing the process can result in incomplete cleaning, streaking, and uneven results.
