Nicolock and Cambridge Concrete Pavers – How to Maintain Them
When it comes to cleaning and sealing, you want to make sure you’re doing it right. The first step involves getting the stones ready. Start by removing any items touching the pavers, such as toys, chairs, tables, etc. Then, if you notice any weeds, pull them out gently. You want to ensure that you’re working on a clear surface. You can also use a broom to scrub any other growth away. At Gappsi, our installers and applicators make sure to do the job right, so you do not need to touch the pavers for any form of maintenance for a long time. While there are basic ways to maintain your concrete pavers without professional help, they might not work every time.
What Types of Cleaning Solutions Should You Use?
There are numerous cleaners for pavers. However, you want to stick to an effective and long-lasting solution. Before you take your pick, make sure to test the solutions on a single stone first to record its reaction to the color. 
Diluted Bleach
You can remove a number of stains by using bleach diluted with ten parts water. The stains this solution can easily remove are tobacco stains, wood rot, and beverage stains.
Water And Soap
Sometimes, hand soap or dishwashing soap is also effective in removing moderate stains and grease. You can make the solution easily by mixing some warm water with soap.
Simple Green
The best cleaning solutions for pavers are those that are chemical-free. You want to ensure that you’re using the least number of chemicals when working with any outdoor structure.

Furthermore, our team will also guide you about ways to clean and seal the pavers yourself.
Preventing Pavers From Fading
It’s important to acknowledge that sooner or later, your outdoor pavers will fade. This is usually because of prolonged exposure to UV rays. With time, you may notice that the aggregate is no longer accepting the color pigments, which will make them appear gray or white the more the color fades. The good news is there are a few ways to slow down fading. One way is to seal them appropriately. This way, the pavers will be able to resist wear and tear for a long time. However, the benefits of sealing don’t end here. Sealing also prevents Nicolock and Cambridge concrete pavers from water penetration, weather conditions, cracks and damages, moss, mold, weeds, and ants. 
How Frequently Should You Opt For Sealing?
At the time of installation, our installer will make sure to apply a sealer to prevent the fading of your pavers. However, doing it once is not enough. As a rule of thumb, you want to go for it every three to five years. If the sun is intense, you want to go for it every three years to maintain the rich appearance of your concrete pavers.
Preparation for Cleaning
Before you start scrubbing, a little prep work goes a long way in making the job easier and more effective. First, you’ll want to completely clear the paver surface. Move any patio furniture, planters, grills, or toys out of the way so you have full access to the entire area. Next, take a moment to pull any weeds that have popped up in the joints between the pavers. Once the space is clear, use a stiff broom or a leaf blower to sweep away all the loose debris like dirt, leaves, and twigs. Getting rid of this surface-level grime ensures your cleaning solution can work directly on the stains and built-up dirt. This simple setup is the first step in any effective restoration and sealing process.
Initial Rinse
After you’ve swept the area clean, give the entire paver surface a good rinse with your garden hose. This step does more than just wash away the last bits of fine dust and dirt. Wetting the pavers before applying a cleaner is crucial because it helps the cleaning solution spread more evenly and prevents it from absorbing too quickly into the porous stone. A pre-rinsed, damp surface allows the cleaner to sit on top and work its magic on the grime, rather than just soaking in. Think of it as priming the canvas before you start painting.
Specific Moss Removal
If you have areas with stubborn moss, mold, or algae, particularly in damp or shady spots, you’ll need to tackle them with a bit of extra effort. Before you apply any cleaning solution, grab a stiff-bristled brush and scrub these green patches away. Physically removing the bulk of the growth is much more effective than relying on a cleaner alone. It requires some elbow grease, but it ensures that when you do apply a cleaning product, it can penetrate the paver surface to handle any remaining roots or spores. Proper landscape drainage and sunlight can also help prevent it from coming back.
Moss and Mold Solution
Moss and mold can be persistent issues on outdoor pavers, especially in damp or shaded areas, but you can manage them with the right approach. Before you start cleaning, it’s important to prepare the surface. Move any patio furniture, planters, or toys off the pavers and gently pull out any weeds that have crept into the joints. This gives you a clear, unobstructed area to work on and ensures your cleaning solution can reach every spot where growth might be hiding. A quick sweep with a stiff broom can also help dislodge any loose debris or surface growth, making the next steps much more effective.
For a potent solution to tackle stubborn moss and mold, you can use a simple mixture of diluted bleach. A good ratio to follow is ten parts water to one part bleach. This can effectively kill the growths and help lift the stains they leave behind. However, you need to be careful. Always test your cleaning solution on a single, hidden paver first to make sure it doesn’t alter the stone’s color. Also, take care to protect any nearby plants or grass from the bleach mixture to avoid accidental damage to your landscaping. Applying the solution with a garden sprayer can help you control where it goes.
If you prefer a more environmentally friendly option, plenty of chemical-free paver cleaners are effective against organic growth. These products are safer for your surrounding plants, pets, and the local ecosystem. While DIY cleaning can certainly improve your patio’s appearance, preventing moss and mold from returning is the real goal. For a long-lasting fix that protects your investment, professional restoration and sealing can protect your pavers from moisture and inhibit future growth. This process not only cleans the surface but also seals the pores of the stone, keeping them looking beautiful for years to come.
Vinegar Solution
If you’re looking for an eco-friendly way to clean your Nicolock and Cambridge concrete pavers, a simple vinegar solution is a fantastic option. The acetic acid in white vinegar is a natural and effective cleaner that cuts through dirt, grime, and even light efflorescence without using harsh chemicals. To create the solution, just mix one part white vinegar with four parts water in a bucket. Before you start, clear the area of any furniture and debris, and be sure to pull any weeds from the paver joints. Then, pour the solution onto a section of the pavers and let it sit for a few minutes before gently scrubbing with a stiff-bristled brush to lift stains and restore their appearance.
Always test this solution on a small, inconspicuous spot first, as the acidity could affect the color or finish on certain types of pavers. This DIY method is perfect for routine upkeep and helps maintain the vibrant look of your patio or walkway. However, for deep-set oil stains or to ensure your pavers are protected for the long haul, consider a professional restoration and sealing service. A professional sealing not only provides a deeper clean but also safeguards your investment against the elements, prevents weed growth, and offers UV protection to keep the colors from fading.
Scrubbing Technique
Once you have your cleaning solution ready, it’s time to apply it. After giving the pavers a light rinse with water, pour your chosen cleaner onto the stained areas. The key to effective cleaning is using the right tool for the job. Grab a stiff-bristle scrub brush, the kind you might use for floors, or a push broom with firm bristles. Gently work the solution into the pavers using a circular motion. It’s important to be firm enough to lift the dirt but gentle enough not to harm the surface. Remember to avoid using wire brushes or abrasive scouring pads. These tools are too harsh and can easily scratch or damage the protective coating on your Nicolock or Cambridge pavers, leaving permanent marks.
A Note on Pressure Washing
Pressure washing can be a tempting shortcut for tackling tough dirt and grime, but it comes with significant risks. While effective, the high-pressure stream of water can be too aggressive for concrete pavers. It can etch the surface, altering its texture and color, or worse, blast away the polymeric sand from the joints. This sand is crucial for locking the pavers in place and preventing weeds. If you’re considering this method, it’s often best to call in professionals who have the right equipment and experience. At Gappsi, our team can restore and seal pavers using specialized techniques to clean them safely. If you decide to do it yourself, always use the lowest possible pressure setting and consider a round brush attachment to disperse the water flow and minimize potential damage.
Risks and Recommendations
Let’s talk more about the risks of pressure washing. When the joint sand is washed away, it compromises the entire paver system. The pavers can shift, become uneven, and create tripping hazards. It also opens the door for weeds and moss to take root much more easily. Damaging the surface of the paver itself is another major concern, as it can strip away the color and protective technologies like ArmorTec. Our recommendation is to always start with the gentlest cleaning method first, like a simple scrub with soap and water. If you must use a pressure washer, keep a safe distance from the surface and use a wide-angle nozzle to reduce the force of the water.
Important Warnings for Cleaning
Before you apply any cleaning solution to your entire patio or driveway, it’s absolutely essential to perform a spot test. Find a small, out-of-the-way area, perhaps behind a planter or near the edge of the installation, and apply a small amount of the cleaner. Let it sit and then rinse it off according to the product’s instructions. This simple step allows you to see how the solution reacts with your specific pavers. You can check for any discoloration or adverse effects before committing to the entire surface. This is a non-negotiable step, whether you’re using a homemade solution or a store-bought chemical cleaner. It’s a few extra minutes of work that can save you from a costly mistake.
Tools to Avoid
When you’re scrubbing your pavers, the tools you don’t use are just as important as the ones you do. As mentioned earlier, you should never use a wire brush or any kind of metal scouring pad. These implements are far too abrasive for concrete pavers. They will scratch the surface, leaving behind unsightly marks that cannot be removed. This is especially true for Nicolock and Cambridge pavers, which have specialized top coats that give them their rich color and smooth texture. Damaging this layer not only affects the appearance but can also reduce the paver’s resistance to stains and weathering. Always stick to stiff, non-metallic brushes to protect your investment.
The Final Rinse Step
After you’ve finished scrubbing and the pavers look clean, the final step is to rinse everything thoroughly. Use a standard garden hose with a regular spray nozzle to wash away all the cleaning solution and loosened grime. It’s important to be meticulous with this step, as any leftover soap or chemical residue can leave a hazy film on the surface once it dries. Make sure you rinse until the water running off the pavers is completely clear. For particularly stubborn areas, you may need to repeat the scrubbing and rinsing process a few times. A complete and thorough rinse ensures your pavers will dry beautifully, leaving you with a clean and refreshed outdoor space.
When to Seal New Pavers
It might seem counterintuitive, but you should hold off on sealing your brand new pavers. It’s best to wait at least six to twelve months after installation before applying the first coat of sealer. This waiting period is crucial for the longevity and appearance of your patio or driveway. It allows the pavers to fully settle into their new home and gives the joint sand time to compact and properly set. Rushing this process can trap moisture and efflorescence, leading to a cloudy finish that’s difficult to fix. Patience here really pays off, ensuring your sealer adheres correctly and provides the best possible protection for your investment.
The Reason for Waiting to Seal
The primary reason for this delay is a natural process called efflorescence. This is the white, chalky residue that can sometimes appear on the surface of new concrete products. It’s simply natural salts making their way to the surface as moisture evaporates, and it’s not a defect in the paver. Giving your pavers several months to a year allows them to go through this initial “breathing” phase. Most efflorescence will wash away on its own with rain and time. Sealing too early traps these salts underneath, which can obscure the beautiful color of your pavers and interfere with the sealer’s bond.
DIY Sealing Instructions
If you decide to seal your pavers yourself, proper preparation is everything. The first and most critical step is to thoroughly clean the entire surface. You need to remove all dirt, grime, moss, and stains, because any debris left behind will get trapped under the sealer. Once the pavers are spotless, you must let them dry completely, which can take a day or two depending on the weather. Apply the sealer with a roller or a sprayer, working in thin, even coats to avoid puddles. It’s always a good idea to test the sealer on a spare paver or an inconspicuous area first to make sure you like the finish.
Sealing Best Practices
To keep your pavers looking their best and protected from the elements, sealing isn’t a one-and-done task. Think of it as regular maintenance. As a general guideline, you should plan to reseal your pavers every three to five years. The exact timing depends on factors like how much foot traffic the area gets and its exposure to direct sunlight and harsh weather. For high-traffic areas or surfaces that get a lot of sun, you might lean closer to the three-year mark. Consistent sealing will help maintain the pavers’ vibrant color, prevent stains, and inhibit weed growth, keeping your outdoor space beautiful for years to come.
Special Maintenance Considerations
Beyond routine cleaning and sealing, your pavers may need some special attention from time to time to handle specific issues. Things like efflorescence, pesky weeds, and the challenges of winter weather are all common concerns for paver owners on Long Island. Knowing how to address these situations will help you maintain the integrity and beauty of your hardscape. For instance, what you use to melt ice in the winter can have a big impact on the surface of your pavers. Similarly, pavers used for a pool deck have unique needs due to their constant exposure to water and pool chemicals. Understanding these nuances is key to proper long-term care.
Managing Efflorescence
Seeing a white, powdery film on your beautiful new pavers can be alarming, but don’t worry. This is just efflorescence, a completely normal and temporary occurrence with concrete products. It’s caused by natural salts migrating to the surface and is not a sign of a defective paver. In most cases, this chalky layer will disappear on its own over time with exposure to rain and regular use. If you want to speed up the process, you can gently scrub the area with a stiff brush and water. For more stubborn spots, specific efflorescence cleaners are available that are designed to dissolve the salt deposits without damaging the pavers.
Weed Prevention
Weeds have a knack for popping up in the most inconvenient places, including the joints between your pavers. The best defense is a good offense, which starts during installation. Using polymeric sand in the joints is the most effective way to prevent weeds. This special sand is swept into the joints and then activated with water, causing it to harden and form a durable yet flexible bond that blocks weeds from taking root. If you do spot a few weeds, it’s best to pull them by hand before they establish a deep root system. For ongoing prevention, keeping the joints topped up with polymeric sand is your best strategy.
Winter Care
When winter arrives on Long Island, you’ll need to clear snow and ice from your paver surfaces. You can safely use a snow blower or shovel, but be mindful of the equipment you use. If you’re using a plow, it should have a rubber edge to prevent it from scraping or chipping the pavers. The same goes for snow blowers; try to avoid direct contact between any metal parts and the paver surface. Taking a little extra care during snow removal will ensure your driveway or walkway emerges from winter looking just as good as it did in the fall.
Ice Melt
Choosing the right ice melt product is critical for the health of your pavers. Standard rock salt, or sodium chloride, is generally safe to use. However, you should absolutely avoid any products containing magnesium chloride. While effective at melting ice, these more aggressive chemicals can cause surface damage and deterioration to concrete pavers over time, and using them may even void your paver warranty. Always check the label before you buy and stick to basic rock salt to keep your surfaces safe for both walking and for the pavers themselves.
Snow Removal Tools
The tools you use for snow and ice removal matter just as much as the chemicals. Never use sharp metal tools, like a metal shovel or an ice chopper, to break up thick ice on your pavers. This can easily lead to chips, scratches, and gouges that are impossible to repair. Instead, opt for a plastic shovel for lighter snow. If you have to deal with ice, apply a safe ice melt product and let it do the work. A gentle approach is always best to protect the surface and ensure your pavers stay in pristine condition through even the toughest winters.
Tips for Pool Deck Pavers
Pavers are a fantastic choice for pool decks, offering a slip-resistant and attractive surface. However, the pool environment requires a bit of special care. Pool chemicals like chlorine can be harsh, so it’s a good idea to rinse the deck with fresh water from a hose periodically to wash away any chemical residue. Proper sealing is especially important for pool decks to protect the pavers from both chlorine and potential salt damage if you have a saltwater pool. At Gappsi, when we design and install paver pool patios, we always ensure proper drainage is in place to prevent standing water, which helps keep the surface clean and safe.

Frequently Asked Questions
Why do I have to wait to seal my new pavers? It’s tempting to seal your beautiful new patio right away, but patience is key. New concrete pavers go through a natural curing process called efflorescence, where mineral salts come to the surface, creating a temporary white haze. Sealing too early traps this haze underneath, which can result in a cloudy finish. Waiting six to twelve months allows this process to complete naturally, ensuring the sealer adheres properly and your pavers look their best.
Is it really necessary to reseal my pavers every few years? Yes, think of sealing as essential maintenance that protects your investment. A quality sealer acts as a barrier against UV rays, which prevents the color from fading over time. It also protects against stains from spills, inhibits weed and moss growth in the joints, and makes routine cleaning much easier. Resealing every three to five years keeps your hardscape looking vibrant and well-maintained for the long haul.
Can I use a pressure washer if I’m careful? While pressure washing can seem like a quick fix, it often does more harm than good. The intense spray can easily strip the color and texture from the paver surface and, more importantly, blast out the jointing sand that keeps everything locked in place. This can lead to wobbly pavers and a surge in weed growth. If you must use one, stick to the lowest pressure setting and a wide-angle nozzle, but for a deep clean without the risk, professional services are a much safer bet.
What’s the most effective way to stop weeds from growing between my pavers? The best defense against weeds is using polymeric sand in the joints of your pavers. When activated with water, this sand hardens to form a strong yet flexible bond that physically blocks weeds from sprouting. If you already have pavers and are dealing with weeds, the solution involves thoroughly cleaning out the joints and refilling them with fresh polymeric sand. This is far more effective than just pulling weeds as they appear.
What should I use to melt ice on my pavers during the winter? When dealing with ice, you need to be selective about the products you use. Basic rock salt (sodium chloride) is generally safe for concrete pavers. However, you should always avoid ice melts that contain magnesium chloride. These stronger chemicals can react with the concrete and cause surface damage and deterioration over time. Always check the product label to protect your pavers through the winter months.
Key Takeaways
- Prioritize safe cleaning practices: You can effectively clean your pavers using simple, gentle solutions like diluted vinegar or mild soap. Always test your chosen cleaner on a small, inconspicuous area first to prevent any unexpected discoloration.
- Seal your pavers to preserve their appearance: For long-lasting color and protection against stains, reseal your pavers every three to five years. If your pavers are newly installed, it’s best to wait at least six months before applying the first coat of sealer.
- Avoid aggressive cleaning methods: High-pressure washing and abrasive tools like wire brushes can permanently damage your pavers by stripping their color and texture. For deep-set stains or a full restoration, professional cleaning and sealing is the safest way to protect your investment.
