Seal-n-Lock Natural Luster is a high-solids, water-based, urethane-modified acrylic specifically designed for sealing pavers, but it also works well on most types of concrete. Natural Luster is designed to seal pavers and lock sand joints, while leaving a natural appearance. SnL NL also contains algae and mold inhibitors to reduce organic growth. Natural Luster does not enhance the color of the surface or have a "wet look".
On pavers, SnL Natural Luster provides a protective barrier with excellent sand joint stabilization. This unique formula can even be used on damp surfaces without the risk of turning white like solvent-based acrylics. Now, instead of waiting for days for your pavers to dry, you can now clean, sand and seal all in one day. Natural Luster has very low odor and applies quickly and easily by sprayer, eliminating the need for rollers, respirators and toxic solvents.
SnL Natural Luster is also perfect for all types of un-sealed outdoor concrete.
Natural Luster comes in a concentrated formula that you dilute with water to make up to 10 gallons of ready to use product! This not only saves big on shipping costs, it also makes Natural Luster cost comparable other "seemingly" less expensive products. See the "Detailed Info" for our recommended mixing and dilution guide.

Note: Sealer being used in video is Seal-n-Lock SuperWet, not Natural Luster. Although mixing and dilution is different, the preparation, application and paver sealing process is the same for both products.
Product Estimate Guide: Coverage rates are approximate and will vary depending on substrate density, porosity and temperature. These rates are for the average amount of concentrate you will need to complete various types of sealing projects. See "Detailed Info" for more about each type of application.

The best choice available if you need to lock sand joints, and must have a natural appearance!
A great sealer, but we still like SuperWet better.
Seal-n-Lock Natural Luster is our only recommended paver sealer for customers looking for a product to stabilize sand joints, but doesn't want an enhanced color or wet look. Natural Luster is extremely easy to apply, performs well and can be used on many types of surfaces including pavers and concrete.
Probably the most advanced feature of the Seal-n-Lock System is it's ability to make cleaning and sealing an easy ONE DAY PROCESS! It's unique composition allows SnL NL to be used on pavers immediately after cleaning, without waiting days for the pavers to dry and without the worry of the sealer turning white from moisture.
Although SnL NL is primarily used for protecting pavers and paver sand joints, it also works well on both Exposed Aggregate and Broom Swept Concrete.
Seal-n-Lock Natural Luster comes in a high-solids concentrate form. This means you get a lot of bang for your buck! See info below for detailed mixing instructions.
Note: Because Seal-n-Lock Natural Luster has many possible applications, be sure to use only the cleaning, prep and application methods that are suitable for the surface you are sealing. The following are basic cleaning, preparation, mixing and application guidelines, but they may not be suitable for every situation. Coverage rates are only estimates and will vary based on surface porosity and size of sand joints.
Cleaning and Preparation Instructions
1. Completely remove all oils and contaminates from the surface. This may be done by hand scrubbing, pressure washing, sand blasting, shot blasting, diamond grinding and/or auto scrubbing. (Although Natural Luster is compatible with many other types of sealers, it is ALWAYS recommend to completely remove any existing sealers or coatings before application) Use only cleaning methods suitable for the substrate you are cleaning. Area to be treated must be clean and not hydro-phobic.
2. Use only the amount of cleaners necessary to remove contaminates, oils, fluids and sealers from the substrate. If using acidic cleaners to remove efflorescence, calcium, rust, etc, be sure to neutralize and restore pH with Balance Neutralizer. Rinse thoroughly! Surface and pores must be clean and free of all chemicals before applying Natural Luster.
3. On pavers, always repair any loose pavers or damaged sand joints before application. Wet-sanding with a coarse angular sand is the recommended procedure. Dry sweeping sand will create weak un-compacted joints that can collapse as sealer is applied. See video on opening tab for more on the wet sanding process. Blow any loose sand from the surface before application.
Seal-n-Lock Natural luster comes in a concentrate form packaged in 5 gallon pails. Before using Natural Luster the concentrate should be diluted with 1 part water : 1 part concentrate. Below, you will find a list of common applications for Natural Luster, along with detailed application instructions and application rates. Use this info to estimate the amount of concentrate you will need to complete your project.
1. Mix concentrate thoroughly with drill and Squirrel Mixer. Concentrate is now ready to be diluted with water. Dilution of SnL NL is simple: 1 part Water : 1 part concentrate.
2. Separately measure the equal amounts of concentrate and clean water needed to make the amount of sealer you need into a clean pail large enough to hold the complete mix.
3. Pour concentrate into equal amount of water. Stir well with paint stick. (Note: Always add concentrate to water. Adding water to the concentrate can cause the mix to foam, especially if from a garden hose)
4. Product is now ready to apply!
1. Using our battery operated pail pump system or pump sprayer, uniformly apply a heavy flood coat of Natural Luster for joint stabilization. Hold sprayer tip 10” – 12” from the paver surface and use overlapping passes to cover the entire area with a heavy flood coat. (avoid overspray on adjacent surfaces, rinse any overspray with water). The purpose of the flood coat is to fully saturate the sand joints and "lock" them together.
2. After flood coat application, a leaf blower can be used to gently move sealer around for uniform application. Avoid leaving any un-absorbed puddles on the surface. Allow flood coat to dry until fully absorbed and no white areas are visible. Natural Luster appears white when initially applied, but dries clear.
3. Now you are ready to apply a lighter top coat (second coat) to complete the sealing process.
4. Make sure all sprinklers are turned off for a 24 hour period of time. Apply Natural Luster only if rain is not expected for at least 24 hours. Do not apply Natural Luster below 50° F.
5. Allow surface to dry for a minimum of 8 hours before foot traffic and 48 hours before vehicle traffic.
Flood Coat = 1:1 dilution applied at 100-125 sq. ft. / gallon
Top Coat = 1:1 dilution applied at 225-250 sq. ft. / gallon
Total Paver Project Estimate Rate = 125-175 sq. ft. / gallon of Natural Luster Concentrate... This means a 5gallon pail should be enough product to complete a 625-875 sq. ft. paver project. This includes both coats and is based on un-sealed pavers with average sand joints. Previously sealed pavers will typically be less absorbent and may require lighter coats, or possibly only one "top coat", depending on condition of the existing sealer.
Exposed Aggregate Concrete:
Seal-n-Lock Natural Luster is a great option for exposed aggregate, especially if you are looking for a product to secure stones, but retain a natural appearance. Since Natural Luster comes in a concentrate form, it is actually price comparable to seemingly less expensive acrylics.
1. Using our battery operated pail pump system or pump sprayer, uniformly apply a single heavy coat of Natural Luster to aggregate surface. Hold sprayer tip 10” – 12” from the concrete surface and use overlapping passes to cover the entire area. (avoid overspray on adjacent surfaces, rinse any overspray with water). Apply heavy enough that sealer begins to pool around the aggregate stones, but no more than half way up the pebbles or stones. If needed, sealer can be gently brushed with a soft, wide applicator brush to remove any puddles and help create a more uniform application.
2. In most cases, one saturating coat is all that is recommended. If additional build is desired, a second lighter coat can be applied. Apply second coat as soon as first coat is fully absorbed and no white areas are visible.
3. Make sure all sprinklers are turned off for a 24 hour period of time. Apply Natural Luster only if rain is not expected for at least 24 hours. Do not apply Natural Luster below 50° F.
4. Allow surface to dry for a minimum of 8 hours before foot traffic and 48 hours before vehicle traffic.
Aggregate Sealer = 1:1 dilution applied at approximately 100 sq. ft. / gallon
Aggregate Sealing Product Estimate Rate = approximately 200 sq. ft. / gallon of Natural Luster Concentrate... This means a 5gallon pail should be enough product to seal approximately 1000 sq. ft. of exposed aggregate.
Broom Swept Concrete:
Seal-n-Lock Natural Luster can be used on all types of un-sealed outdoor concrete. Natural Luster should be applied to broom swept concrete using multiple light coats, rather than one heavy coat.
1. Product can be applied in either a 2 or 3 coat process, depending on porosity and build desired.
2. Using our battery operated pail pump system or pump sprayer, uniformly apply an even wet coat of Natural Luster to concrete surface. Use overlapping passes and a fine spray tip to cover the entire area. (avoid overspray on adjacent surfaces, rinse any overspray with water). Apply only enough to evenly wet the surface. Do not allow to puddle.
3. Allow first coat to dry until fully absorbed and no white areas are visible. Second coat can now be applied in the same manner as first coat. (if only applying two coats, proceed to final top-coat application)
4. Final clear top-coat can now be applied as soon as previous coat has fully absorbed and no white areas are visible. Apply in the same manner as previous coats, applying only enough to evenly wet the surface. Do not allow to puddle.
5. Make sure all sprinklers are turned off for a 24 hour period of time. Apply Natural Luster only if rain is not expected for at least 24 hours. Do not apply Natural Luster below 50° F.
6. Allow surface to dry for a minimum of 8 hours before foot traffic and 48 hours before vehicle traffic. Remember, colored concrete can be easily damaged by scraping, shoveling and the use of snow blowing equipment!
First Coat = 1:1 dilution applied at 200-225 sq. ft. / gallon
Second Coat = 1:1 dilution applied at 250-300 sq. ft. / gallon
Top Coat = 1:1 dilution applied at 225-275 sq. ft. / gallon
Total Broomed Concrete Project Estimate Rate = approximately 150-175 sq. ft. / gallon of Natural Luster Concentrate... This means a 5gallon kit should be enough product to complete a 750-875 sq. ft. broom swept concrete project. This includes three coats and is based on bare concrete with no previous sealer. Previously sealed concrete will typically be less absorbent and may require lighter and/or fewer coats, depending on condition of the existing sealer.

Like all things, maintaining optimal protection of a sealed surface requires scheduled maintenance. Once properly applied, surfaces sealed with Natural Luster may periodically require a light cleaning to remove dirt, dust, mud, etc. In most cases, low pressure water is all that is needed for routine cleaning. Do not use a hot-water pressure washer unless you are preparing to apply a maintenance coat of Natural Luster. Depending on wear and tear, sealed surfaces typically need a maintenance coat every 2-3 years.
