Hardscapes 101
Pressure washing hardscapes like pavers, bricks, and blocks is essential for maintaining their longevity and appearance. Over time, these surfaces accumulate dirt, grime, algae, moss, and stains, which not only affect their aesthetic appeal but can also lead to degradation. Regular cleaning helps to prevent the buildup of organic matter, which can cause discoloration and even structural damage if left unchecked. With pressure washing, you ensure that these surfaces remain in optimal condition, preserving both their functionality and visual appeal for years to come.
Pressure washing with high-quality detergents also helps to maintain the integrity of hardscapes by preventing the growth of harmful elements like mold and mildew. These substances thrive in damp, dirty environments and can penetrate porous materials such as concrete, brick, and stone. Without regular cleaning, they can weaken the material, leading to cracks, erosion, and a higher risk of costly repairs. A professional-grade detergent designed for pressure washing can enhance the cleaning process, ensuring deep penetration and effective removal of contaminants while also protecting the surface from future buildup.
Introduction to Hardscape Products

How to Apply NMD 80™
Dilutions
NMD 80™ is diluted 4 parts water to 1 part NMD 80™. An EC Jet is recommended to ensure both proper dilution and application of NMD 80™. Ideal size of pressure washer for exterior cleaning: gas-powered ranging from 3 to 6 gallons per minute pressure washer not to exceed 3,000 P.S.I.
Coverage Rates
Coverage rates with NMD 80™ using an EC Jet will vary from 100-200 sq. ft. per gallon depending on the surface porosity, texture, ambient temperature, craftsmanship, severity of mortar smears, and severity of other post construction staining.
Application Instruction
Low Pressure Application
- Lightly pre-wet or flash-cool the surface (do not soak).
- Apply NMD 80™ through an EC Jet to the entire section to be cleaned. Start from the top and work down. Allow NMD 80™ to dwell for 5-7 minutes.
- After the initial application of chemical, scrape the large chunks of mortar with a long-handled scraper.
- Check mortar smears and tags to see if it crumbles easily.
- Reapply NMD 80™ without rinsing between applications to melt the remaining mortar residue and extend dwell time. Once there is no foaming, the surface is ready to be rinsed.
- With NMD 80™, the longer it stays wet on the wall, the cleaner the end result. This will also reduce the amount of rinsing required. After reapplication, scraping can be done further down the wall.
- Begin rinsing from top down. Use long even strokes that overlap each other. Caution: Do not allow the product to dry on the surface.
Rinsing
Proper rinsing techniques determine the final look and quality of the job. Generalized rules of rinsing would include:
- Low pressure rinse. The EC-Jet can be used as long as the ball valve to NMD 80™ has been turned to the off position.
- If using a pressure washer to rinse, use a 40-degree nozzle to reduce the potential for surface damage. Stay at least 8”-12” from the wall to avoid potential damage to the mortar joints. Do not use a zero-degree nozzle.
- Craftsmanship determines the appropriate pressure for rinsing. A thorough rinse job is recommended; however, our chemistry never requires flooding a wall. Pressures that mark or damage the surface should be avoided. If in doubt, follow the manufacturer’s recommended P.S.I. for the substrate you are working on.
- Always use overlapping horizontal passes to achieve a uniform appearance
Note: Sensitive surfaces such as sand faced brick, concrete brick, synthetic masonry and surface dyed substrates, need to be rinsed at low pressures. Use the EC Jet with the ball valve turned to the “off” position for rinsing or a garden hose with nozzle. The rinse pressure should be about 50 P.S.I.

vanadium, manganese, mineral oxide stains, pollution stains, concrete leaching, caulk bleed, hard water stains on glass, sealer overspray on glass, sealant stains, fresh tar stains
How to Apply OneRestore®
Dilutions
OneRestore® is always used undiluted.
Coverage Rates
Coverage rates with OneRestore® will vary from 75-250 sq. ft. per gallon depending on the surface porosity, texture, ambient temperature, craftsmanship, and severity of staining.
Application Instructions
- Pre-wet the surface (do not saturate) with water before applying OneRestore®.

- For most instances, a single application with a 5-to-10-minute dwell time will remove many of the stains.
- For deeper stains or very porous surfaces, a double application with 5 to 10 minutes in between applications will provide the best results. Do not rinse between applications.
Rinsing
Proper rinsing techniques determine the final look and quality of the job. A thorough rinse job is always recommended; however, our chemistry never requires flooding the surface. OneRestore® can be rinsed using cold water. Pressures that mark the surface should be avoided. When in doubt, follow the manufacturers recommended P.S.I. for the substrates.
Do not use a zero-degree nozzle
Caution: Do not allow the product to dry on a surface.
As a professional-grade window and multi-surface restoration product, OneRestore® contains a high level of proprietary components that include solvents, acids and soaps. This blend enables it to perform in situations that require industrial-strength cleaning capabilities. As with any powerful restoration product, care must be taken to use it as directed.
Since OneRestore® is a water-based product, the water portion of the blend will evaporate quickly on hot surfaces. This will leave the highly concentrated chemical behind.
OneRestore®’s high concentration of soaps must be thoroughly rinsed with water from any surface it is used upon. It is not designed to be wiped or squeegee-ed off the surface without a water rinse.
Principle Points Regarding OneRestore®
- OneRestore® ships and is considered non-hazardous/non-corrosive in its concentrated form. That is, it does not damage glass, paint, skin, or other substrates undiluted.
- Chlorine, the principal engine of OneRestore®, it is present in all water that is treated for consumption in the U.S.A.
- Neutralization has not been left to chance in this instance. OneRestore® is acidic and once you have applied the product to alkaline materials such as (limestone, mortar, aggregate, etc…), the two run over each other creating neutralization before the chemical runs off. Cleansol BC is used as a second step prior to rinsing to assure neutralization of any remaining residues.
Recommended Disposal of Spent Product
OneRestore®’s DOT shipping classification is non-hazardous liquid, not regulated by the DOT. The product does not contain any known hazardous ingredients that would be rejected or deemed inappropriate in its waste stream by a municipal sanitary treatment plant. Prior tests have shown this product can have a neutral pH after use on a masonry surface followed by the subsequent rinse.
If the product is not neutral, test spent liquid with either pH strips or a pH meter to determine the pH. We recommend neutralization with natrium perborate monohydrate, which may be available locally or can be purchased from EaCo Chem Inc. If the spent OneRestore® product has been collected, the next step should be to dispose of it to a sanitary sewer outlet.
It may be appropriate to check with the sanitary treatment plant in question if prior approval is desirable. (The SDS for OneRestore® can be used to indicate the hazards present in the product when contracting the water treatment plant to make this prior determination.)
EF-Fortless
EF-Fortless is a soap solution that melts powdery efflorescence and haze from cleanup efflorescence and helps to control its return. This product is mildly acidic and great for use on color sensitive surfaces since it will not discolor brick, block or mortar. It can be used on slurry-dyed blocks and similar substrates.
Simply apply EF-Fortless straight and wait for foam to collapse. Reapply as needed. No rinsing required. The amount of coverage will vary with the thickness of the efflorescence; with the most common powder type getting approximately 75 square feet per gallon. This product offers long-term protection. Surface can be sealed after one week.
Advantages of EF-Fortless

How to Apply AcrylicStrip
Dilutions
AcrylicStrip is always used undiluted.
Coverage Rates
Coverage rates will vary based on porosity, severity and type of coating, application method, and other factors. Proper testing will determine actual coverage rate.
Application Instructions
- Apply AcrylicStrip to a dry surface through a low-pressure application system; or AcrylicStrip can be applied with a dry brush, rag, or roller.
- Apply AcrylicStrip from top down using a side-to-side motion.
- Allow AcrylicStrip to dwell for a minimum of five minutes before doing a scratch test.
- If substrate is visible after conducting the scratch test, you are ready to rinse. If the substrate is not visible or the coating is gummy but not released, re-apply AcrylicStrip and allow to dwell for an additional ten minutes.
Rinsing
Use only cold water to rinse. Proper rinsing techniques determine the final look and quality of the job. A thorough rinse job is always recommended; however, our chemistry never requires flooding the surface. AcrylicStrip should be rinsed using cold water using either a pressure washer, garden hose, or water and brush. When using a pressure washer on wood, be sure to keep the nozzle at least six inches from the surface. Pressures that mark the surface should be avoided. When in doubt, follow the manufacturers recommended P.S.I. for the substrates.
Do not use a zero-degree nozzle.
Caution: Do not allow the product to dry on the surface.
Note: Certain enamels may be best stripped with LCS (Liquid Caustic Stripper). Alkyd enamel can be removed by first applying AcrylicStrip; allow several minutes dwell time; while still wet, apply Stripper Cream directly over the AcrylicStrip. After adequate soak time and a scratch test, remove with a scraper or high-pressure rinse using cold water.
Additional Info on Applying AcrylicStrip:
AcrylicStrip is best applied through a low-pressure application system, but can be brushed, wiped, or rolled on the surface. Coverage is expected to be between 250 to 400 sq. ft. per gallon. Results will be faster and more complete on horizontal surfaces.
Depending on the paint or coating involved, more than one application may be needed. Apply the chemical from the top down using a side-to-side spray. A small hand pump garden sprayer works very well for small jobs. Allow AcrylicStrip to sit on the surface for at least five minutes before doing a scratch test.
When you are doing the scratch test and you see that the coating is releasing from the substrate, you are ready to rinse. If you do not see the surface or the coating is gummy, reapply the product and wait an additional 10 minutes before retesting. Pay careful attention to sheltered areas under overhangs or railings, as these areas see less harmful weathering and fading and therefore may need repeated applications. Rinsing may be accomplished with a pressure washer, garden hose, or water and a scrub brush.
If you find that surface under your paint is gray or weathered, try some Britenol to restore it to the original color without harming the surface.
If you are using a pressure washer to rinse wood, keep the nozzle six inches from the surface.
Calcite Presoak

- Re-apply Calcite Presoak undiluted without rinsing directly to the same affected areas.
- Do a scratch test to determine if you can see the substrate beneath the calcite. If not, repeat steps 1 and 2.
- Once the substrate is visible beneath the calcite, Apply NMD 80 diluted 4 parts water to 1 part NMD 80 over the treated area. Heavy white foam will form. Calcite is completely removed once white foaming ceases.
- Complete with another application of NMD 80 diluted 4 parts water to 1 part NMD 80. As long as there is no white foaming, you are ready to rinse.
Note: Do not allow Calcite Presoak to run down the surface as bleaching may occur. Apply enough product to the calcite deposits without over soaking to avoid runs. If runs occur, rinse the excess immediately.
Rinsing
Proper rinsing techniques determine the final look and quality of the job. A thorough rinse job is always recommended; however, our chemistry never requires flooding the surface. Calcite Presoak and NMD 80 4:1 can be rinsed using cold water. Pressures that mark the surface should be avoided. When in doubt, follow the manufacturers recommended P.S.I. for the substrates. Do not use a zero-degree nozzle.
Caution: Do not allow the product to dry on the surface.
Why Clean After Installation
Hardscape masonry units have been used for years to enhance outdoor spaces, parks, campuses, country clubs and many other places. While they can create a very inviting environment, they can also have unsightly appearances.
These masonry units can inherently have a little dust or film on them from the manufacturing and storage process. Cleaning these units properly after installation, whether vertical or horizontal, will typically remove any dust or film and leave the units clean and crisp!
Regardless of whether they are clay or concrete pavers, natural or synthetic paving stones or concrete retaining wall blocks, it is very important to clean after installation to:
- Enhance the overall color
- Remove job site dirt and debris left behind by the installers
- Remove any imperfections caused by the manufacturing or storage process
- Allow the unit to properly breathe to help prevent future water derived staining
- Prepare the surface for sealing if desired
These masonry units can also have other issues on them before installation, such as:
- Efflorescence
- Scuff Marks
- Secondary Hydration or “Halos”
- Hard Water Stains
Proper cleaning with the appropriate chemicals and equipment can almost ensure that your customer will be completely satisfied with your service when you leave the job site.

The EC Jet is a quick coupling attachment to the end of your pressure washer wand. It is designed to dilute material 4 parts water to 1 part chemical. It is used with the application of NMD 80™ or SOS-50 for new construction cleaning.
Using NMD 80™ with EaCo Chem’s innovative EC Jet pressure washer wand, will reduce cleaning time 90% versus traditional bucket and brush cleaning.
The EC Jet allows for quick and accurate dilutions while spraying the chemical with the best nozzle. The open/close valve can also be used to shut off the chemical flow and allow rinsing without removing the unit.
For the best results, a 3 to 5 gpm pressure washer is recommended.
The Right Equipment
The proper equipment will always make the cleaning project go much more smoothly. You would never try to hammer a screw in, so why use the wrong equipment to clean hardscape?
Before you get started, make sure you have the following items with you:
A 3 to 5 G.P.M. unit is recommended with 2,000 P.S.I. for optimum efficiency. Unit should not exceed 2,000 P.S.I.
To help prevent any spills or drips on the paver surface. Should be wide enough and deep enough to capture any liquid if the bucket spills.
Quick couples to the tip of pressure washer wand. It comes with 30′ of hose to allow cleaning of 1,800 square feet of surface. To rinse, simply shut off the chemical intake valve.
TIPS NEEDED ON PRESSURE WASHER TO WORK WITH EC JET FOR PAVERS:
Quick connect nozzle necessary for use of EC Jet for Pavers.
Screwed into pressure washer wand. This type of system will not work with the EC Jet for pavers unless it is connected with an adapter.

The Cleaning Process:
Applying NMD 80™ with the EC Jet
Testing is always recommended prior to any cleaning project. Although this process has been tested and proven effective, every situation is different and can present different challenges.
Allow the test area to dry thoroughly before evaluating the final results.
After Pavers have been installed and before landscaping has begun, follow the procedures below to remove efflorescence, job site debris, and dirt:
- Lightly pre-wet (do not soak) the paver surface.
- Apply NMD 80™ through an EC Jet using overlapping strokes to achieve even coverage.
- Allow the product to dwell for 5-7 minutes. Do not allow the product to dry on the surface.
- Re-apply NMD 80™ through an EC Jet to melt away the remaining efflorescence, job site debris, and dirt. *With NMD 80™, the longer it stays on the paver surface, the cleaner the end results. It has been noted that longer dwell times produce a decrease in the water rinse.
- Begin rinsing from the highest elevation to the lowest. Use long, even strokes that overlap each other. Low pressure rinse is recommended through the EC Jet (turn off the soap valve and rinse). If a pressure washer is unavailable, a garden hose may be used.
*When using a pressure washer, a wide tip nozzle is suggested. Care should be taken near the joints not to “blow” the sand out.
Scuff Marks
The cleaning process after installation will always begin the same, pre-wet (do not saturate) the surface. The main differences will be in the dwell time of NMD 80™ or adding a secondary product, such as White Scum Presoak. Since every paver is manufactured under various circumstances, the process can also vary! Much like the normal cleaning process, testing is necessary to determine which protocol is appropriate.
Scuff Marks will generally occur when the pavers have peaks and valleys. This is caused by the layer above rubbing the peaks. Cleaning after installation will even out the appearance of the peaks and valleys.
The cleaning process is the same general cleaning after installation, however the dwell time for NMD 80™ needs to be extended to remove the scuff marks.
Allow the product to dwell for 7 to 10 minutes. Do not allow the product to dry on the surface. Re-apply as necessary to keep the product wet.
The key to removing the scuff marks is to allow extended dwell times.
Water Stains
Hard Water Stains can occur on concrete tiles due to the shrink-wrapping process that can trap moisture in it. When this happens, streaks appear on the surface, typically running down. Proper cleaning after installation will remove these streaks.
The process to remove hard water stains (streaks) from concrete tiles is the same as cleaning pavers after installation. Additional applications may be required, depending on the severity of the streaks.
Secondary Hydration or "Halos"
Secondary Hydration or “Halos” (shown below) can be present before pavers are installed. Cleaning after installation can remove these unsightly stains and restore the pavers to their natural color!
- Lightly pre-wet (do not soak) the paver surface.
- Apply NMD 80™ through an EC Jet (or pump sprayer dilutes 4:1) using overlapping strokes to achieve even coverage. Allow the product to dwell for 5 to 7 minutes. Do not allow the product to dry on the surface.
- While the NMD 80™ is dwelling, apply White Scum Presoak through a pump sprayer using a cone shaped nozzle only to the areas where secondary hydration or halos are present.
- Multiple applications of White Scum Presoak may be required to completely remove stains.
- Do not rinse between applications.
- Re-apply NMD 80™ through an EC Jet (or a pump sprayer diluted 4:1) to restore the appropriate color (presoaks can whiten the color).
- With NMD 80™, the longer it stays on the paver surface without drying, the cleaner the end results.
- It has been noted that longer dwell times produce a decrease in the water rinse.
- Begin rinsing from the highest elevation to the lowest. Use long, even strokes that overlap each other. Low pressure rinse is recommended through the EC Jet (turn off the soap valve and rinse). If a pressure washer is unavailable, a garden hose may be used.
- When using a pressure washer, a wide tip nozzle is suggested.
- Care should be taken near the joints not to “blow” the sand out.
- If there are still spots with secondary hydration present after rinsing, repeat steps 3 and 4 just to the areas where they are still visible. Thoroughly rinse again to remove remaining stains and chemical.
Oil Stains
Oil stains, such as the one pictured can be very difficult to remove. There are methods to absorb the physical oil, however the trouble comes with removing the stain left behind!
- Pre-wet (not soak) the area with water before applying the product.
- Dilution will vary depending on the severity of the stain from undiluted to 10:1
- Allow Hot Stain Remover to dwell 15 minutes to an hour. Hot Stain Remover should have an extended dwell time as it contains special additives that cause the stain to rise to the surface.
- Thoroughly rinse.
Rust
- You can use OneRestore® for rust removal.
- Single to double application may be necessary.
- Pressure wash rinse using appropriate pressure.
Efflorescence
Efflorescence can appear as a white powdery substance on the surface of pavers or retaining walls. It is also one of the most common and easiest things to remove. There are two simple remedies to this problem, NMD 80™ or EF-Fortless.
Applying NMD 80™ through an EC Jet (or a pump sprayer diluted 4:1) to a prewet surface, just as installation cleaning, will remove efflorescence on a larger scale. Multiple applications may be necessary based on severity of staining. Once there is no more efflorescence detected, a thorough rinse is required.
Applying EF-Fortless through a pump sprayer undiluted will also remove efflorescence on a larger or smaller scale. Rinsing is still required.
White Scum
White scum has a very similar appearance to efflorescence; however, it is slightly more difficult to remove. The process is the same as removing secondary hydration or “halos”.
As you can see by the example in the picture, the entire surface can be affected by white scum, therefore you will not “spot treat” certain areas. You will apply NMD 80™ through an EC Jet (or a pump sprayer diluted 4:1); then without rinsing, apply White Scum Presoak undiluted to the affected area, followed by another application of NMD 80™. Multiple applications of White Scum Presoak may be necessary, so testing first is extremely important to determine the correct number of applications needed. Once the white scum has been lifted, rinse thoroughly.
Additional Tips for Using NMD 80™ and SOS-50
• With NMD 80™ and SOS-50, the longer it stays wet on the wall, the cleaner the result and the least amount of rinsing is required. After reapplication scraping can be done further down the wall.
• Choose the rinse style: brick, split face and common block, natural stone, and precast use a high-pressure rinse. For smooth dyed block or brick and synthetic stone, use the EC Jet for a low-pressure (50 P.S.I.) rinse.
• The amount of foaming reaction will lessen with each application. When you apply NMD 80™ to a wall that is thoroughly cleaned, there will be little to no foaming as it contacts the wall. Rinse time will be dramatically reduced.
• Pressure washers equipped with a down stream chemical injector (after the high-pressure side) should have the injector removed before using the EC Jet. If the chemical injector is attached with a quick coupler, simply uncouple it and attach the pressure hose in its place. If the chemical injector is hard plumbed in place, simply place the chemical hose in a five-gallon bucket full of water when using the EC Jet.
