Concrete Sealing Schedule Filling Up

October 30th, 2009

If you are thinking about having your concrete driveway sealed before the winter, please contact us today.  We can only seal concrete when it stays above freezing at night and isn’t wet.  That means we don’t have much time left in our season and our schdule is almost full.  We are working hard to seal and protect as many concrete driveways as possible before winter.  You would be surprised at the damage a single winter can inflict on concrete – especially newer concrete.  Be safe and seal your concrete now.  If you wait too long we may not be able to seal it until spring.  Don’t take chances and call today!  913-575-1469

How Sealing Your Driveway Is Like A Vaccine…

October 21st, 2009

Before the winter, you may need to permanently seal and vaccinate your driveway against preventable diseases such as scaling, spalling, and surface cracking.  You might be at risk for if you live in an area with frequent freezing and thawing during the winter: (Note: Your professional concrete sealing contractor will determine what you will need, depending on factors such as the age of the driveway and treatment history, area of the country you live, and accident liability.)


To have the most benefit, consult a Sealwize distributor in your area at least 4–6 weeks before the first freeze of the season to allow time for your driveway vaccine to take effect and ensure enough time to get on the busy fall schedule. 


Even if you have less than 4 weeks before winter begins, you should still contact a Sealwize distributor for needed vaccines and obtain additional information about how to protect your driveway from illness and injury during the winter.


Sealwize of Kansas City recommends that you consult a professional concrete sealing contractor who specializes in preventative treatments that permanently strengthen concrete and protect against deicing salts.  If your driveway has any preexisting conditions, you should still seek treatment so the condition does not become more severe.  Sealwize distributors typically do not provide restoration or remediation services, and instead specialize in prevention. 


Preventative exterior concrete sealing is recommended even if your driveway currently appears healthy and unblemished.  In fact, this is the best time to seal and protect your driveway.  And at less than 1/7th the typical price of replacement, it is difficult to accept the risk of inaction. 


Permanent concrete sealing in Kansas is kind of like getting a Yellow Fever vaccine before traveling to Central America for three months a year every year.  You know the risk, and it is always better to be safe than sorry at a fraction of the cost and hassle.  If you think about it this way, driveway spalling and deterioration is a vaccine-preventable condition.  Permanent concrete sealing from Sealwize is the closest thing to a preventative vaccine for driveway scaling, spalling and deterioration. 


If you would like to have your Kansas City area concrete driveway sealed, please request an estimate online.  One of your knowledgeable and friendly staff will follow up to schedule a no hassle free consultation and estimate.  Or you can call us at 913-575-1469.

How to Choose a Concrete Driveway Replacement Contractor

October 11th, 2009

Your concrete driveway looks terrible and you’re finally ready to replace it.  But you are a little intimidated by the process of selecting a concrete driveway installation contractor and want to make the right choice to avoid concrete defects and contractor hassles.  You know that when it comes to concrete, quality matters.  There is a lot of information available on the internet but you just wish someone would put together the executive summary for you.


You’ve come to the right place.  This article is written to help you ask the right questions and define the proper requirements for your concrete driveway replacement project.


Where to Find Qualified Contractors

Your first goal is to find an experienced quality contractor who is right for the job and will deliver not only on time and on budget, but pour a concrete driveway that is free of defects and will last forever.  The last thing you want is an expensive concrete project gone wrong with cracks, pock-marks and other surface deterioration (scaling, spalling, delamination).  So where can you find a pre-screened honest, competent, professional contractor with good consumer ratings that will be easy to work with and fair in the process?  Seek a referral from someone that has already been through this process or visit


If you go the referral route, be sure to only pursue the referral if the property owner had their concrete driveway repoured three to five years ago.  Typically, the majority of concrete surface deterioration will occur within the first five years.  Don’t just go with the contractor your neighbor used if the concrete was only poured recently. 


In addition to good ratings on sites like Angie’s List or Service Magic, try to go with concrete contractors that are members of the Better Business Bureau.  This is important in the event issues arise. 


Select Licensed Concrete Contractors

Ensure that the contractor you select is licensed in your county and carries both liability and workmen’s compensation insurance.  Typically, contractors must have the proper insurance and proof of qualifications to get a license so this is very important.  For homeowners in Kansas City, use the links below to validate contractor license information. 


Johnson County, KS Licensed Concrete Contractors

Jackson County, MO Licensed Concrete Contractors


Don’t hire unlicensed contractors to do the job. If you do, you will have no recourse should you be unhappy with the job or should you have code or permit violations cited by your county.


Get Multiple Estimates

Even though you are busy, try to get at least three written estimates.  If you use Service Magic the process is simple because your request for an estimate will be sent to multiple local contractors.  Note which contractors show up on time and demonstrate experience, knowledge, and professionalism.


Check References

Get at least three references for your contractor and call them. The contractor will likely give you references who had positive experiences, so be sure to ask them specific questions about workmanship that are important to you.


Check Better Business Bureau Record

Check with the Better Business Bureau to find out if complaints have ever been filed or are outstanding against the contractor.


Sign a Written Contract

The contract should clearly spell out all the steps the contractor will take from beginning to end of your job, what supplies are included, the payment schedule and the time line for the project.  Use the requirements below and ensure they are included in your written contract. 


Defining the Requirements

If you want strong, good quality concrete that will withstand the test of time, experts would agree to use the requirements below:


Strength - The minimum recommended strength for exterior slabs is 4,000 psi (pounds per square inch).  However, this is the minimum and 4,500 psi driveways are even better. 


First Delivery – Try to ensure your job is the first delivery of the truck load and avoid being the last delivery of the day.  This will reduce the probability that additional water is added to the mix that may alter the ratio of ingredients that make up the batch result in weaker bonds. 


Weather - Try to schedule concrete placement when the weather is cloudy and overcast. Concrete placement in weather extremes is very hard on the material. Concrete loves to be placed when the air temperature is in the mid 50sF. Placing it in blazing sunshine or snowy days is simply not a good idea.  Try to have the concrete poured at least thirty days before the next freeze. 


Finish Type – For concrete driveways and sidewalks, go for the more slip resistant broom/brush textured finish. 


Finishing Techniques – Ensure that the concrete finishers do not sprinkle lots of water on the surface of the concrete as they trowel it.  This will dilute the concrete mix on the surface.  If you are the first delivery of the day and have the concrete poured in mild, overcast weather, this will be less of a problem. 


Curing Techniques – Insist on natural wet moist curing or plastic curing.  Do not allow the concrete contractor use a spray liquid curing compound.  Commonly referred to as “cure-n-seal”, these curing agents create a film-like membrane on the surface of the concrete that will allow the concrete to set up properly but will prevent you from applying a penetrating strengthening sealant soon after.  The cure and seal is misleading.  It may help cure the concrete but it certainly will not seal and protect it.  Choose the moist cure or plastic cure (tightly covering the slab with high-quality plastic for several days) for best results.  The hydration process will typically last 30 days.


Expansion Control Joints – Concrete shrinks as it cures and therefore expansion control joints are highly recommended.  The depth of these joints should be one fourth the total thickness of the slab.  So for example, a four inch think concrete sidewalk should have one inch deep control joints. 


Seal Concrete Driveways After 30 Days

You’ve done your research to find the right concrete flatwork contractor and defined the proper requirements for high quality concrete, now the last step is to seal and protect your new concrete driveway or sidewalk.  Be sure to avoid short-service life acrylic sealers or sealers that need to be reapplied.  For the best long-term results, select a lithium-based concrete sealant, hardener, and densifier that will tighten the surface pores and strengthen the concrete to make it less absorbent and less susceptible to surface deterioration.  The result will be a permanently protected driveway that is worry free and easier to maintain. 


Do Not Use Deicing Salts

Do not use deicing salts within the first two years after the concrete has been poured.  Instead, use snow removal services with sand and or kitty-litter.  If you need deicing salts for safety purposes, ensure you use a commercial grade concrete sealant that not only strengthens, hardens, and densifies concrete, but also contains a silane/siloxane salt barrier that neutralizes harmful chloride ions.  The Sealwize LithiSeal Zli71 commercial grade concrete sealer is ideal if deicing salts are necessary.

Concrete Driveway Sealing

September 22nd, 2009

Concrete Driveways

Concrete driveways are common across the United States because they are not overly expensive, typically have a long service life, require limited maintenance, and look nice.

However, most concrete is porous and vulnerable to surface deterioration caused by frequent freeze thaw cycles and deicing salts.  This type of surface deterioration is referred to as spalling and scaling.

What Causes Spalling and Scaling?

Essentially, spalling and scaling is when the top layer of the concrete breaks down or flakes away exposing the stone aggregate underneath.  And once this deterioration begins it can be difficult to stop and impossible to reverse.  It just keeps getting worse every winter.  This type of damage typically occurs for two reasons: 1) poor quality concrete and/or improper finishing techniques, and 2) the concrete was not sealed to protect it from the elements.

However, the good news is that concrete sealants can increase the strength and extend the life of concrete to protect against.

De-icing Salts

Solvent-based snow and ice melt can also damage concrete and steel concrete reinforcements.  As salts melt snow and ice to water they enter the concrete and leave corrosive deposits and increase the number of freeze-thaw expansion cycles.  And although some claim that de-icing salts themselves do not directly cause damage, many with first hand experience would argue otherwise.  Many homeowners have complained that a driveway was blemish free in the fall and noticeably pitted and flaking in the spring.  This is especially true and more common for newer green concrete less than two years old.  See the picture below!

Choose Sealwize Sealers to Protect Concrete Driveways

Some high quality concrete is strong enough to withstand freezing water expansion.  However, it is difficult to tell whether or not you have high quality concrete.  To be safe, you should use a deep penetrating lithium-based concrete hardener/densifier for the best long-term protection.  And for maximum protection, choose a high solids content commercial grade lithium silicate silane siloxane hybrid concrete sealant that hardens, strengthens and densifies concrete making it less absorbent and less susceptible to deterioration and contains a water repelling salt barrier that neutralizes harmful chloride ions.  For this type of protection you might expect a ridiculous price tag but you would be surprised – the cost is only slightly higher than other lower performance treatments.   Most experts would agree that you should avoid silicones, epoxies and acrylics all together because they do not allow the water vapor to escape and need to be reapplied frequently.  All three Sealwize concrete sealants are water vapor permeable and allow the concrete to breathe and release water vapor, which is critical for performance.  When applied, the Sealwize concrete sealants will not change the appearance or surface traction but the invisible barrier is noticeable every time it rains.

Properly sealing concrete when it is still undamaged is critical for maintaining a healthy, unblemished driveway and will enhance the value and appearance of your property.

Commercial Grade Concrete Sealer

September 12th, 2009




LITHISEAL ZLi 71 is a clear, solvent-free, odorless, VOC compliant, water-based environmentally safe-to-use salt barrier and dust proofer that seals, hardens and densifies concrete and masonry.


LITHISEAL ZLi 71 was developed to treat a wide variety of mineral substrates including architectural concrete, concrete block, splitface block, pavers, stucco, porous and dense brick, clay tile and exposed aggregate concrete. It has been found to be particularly effective in commercial concrete sealing applications where high water repellency performance is required.



LITHISEAL ZLi 71 incorporates the sealing, hardening and alkali-silica reaction (ASR) preventing properties of lithium silicate with the chloride protection of silane/siloxane, all in a single, permanent application. LITHISEAL ZLi 71 forms an effective chloride ion screen providing unmatched protection against water and water-carried salts that cause erosion, deterioration and corrosion. LITHISEAL ZLi 71 can be used as an interior or exterior treatment for both horizontal and vertical concrete and masonry. It is perfect for parking garages, bridge decks, brick structures, historic restoration and integrally colored concrete.


LITHISEAL ZLi 71 proprietary silane/ siloxane technology provides excellent water repellency to reduce cracking, spalling, freeze/thaw damage, chemical degradation, biological growth, efflorescence, and dirt pickup, thereby lengthening substrate life and reducing maintenance costs.


LITHISEAL ZLi 71 helps prevent Alkali-Silica Reaction (ASR), a serious problem that occurs when the alkali in the large and fine aggregates reacts with the silica in the cement and with water to form an expansive gel, which can break concrete apart. Other chemical hardeners use potassium or sodium compounds, which can raise alkalinity and contribute to ASR. LITHISEAL ZLi 71 uses lithium technology that does not contribute to the alkalinity and can even prevent surface ASR.


LITHISEAL ZLi 71 meets industry standards (NCHRP 244) for protecting concrete against chloride intrusion. (89% + effectiveness)


LITHISEAL ZLi 71 is vapor permeable to resist cracking, peeling and blistering. This lengthens substrate life and allows for greater structure strength over time.


LITHISEAL ZLi 71 protects gray and colored concrete from weathering and efflorescence thereby reducing maintenance, cleaning costs and repairs.

Active Ingredients: 100% of total solids
Weight/Gal: 9.28 lbs/gal
Specific Gravity: 1.14

New concrete should be allowed to cure for at least 28 days before applying LITHISEAL ZLi 71. In addition, any repair work should be performed at least 3 days before application.



Typical drying time is 1-2 hours for both horizontal and vertical surfaces.


Horizontal surfaces are ready for foot traffic and use when dry. Vehicle traffic should be kept to a minimum for at least 24 hours. A light lithium residue may form on the surface after the surface is dry. This is excess solution that was not absorbed and can be removed with a stiff broom. Caution: During application, surfaces wet with solution may be slippery.
Water repellency and hardness continues to develop for up to 20 days following the application; however, significant results should be visible within 24 hours.
Note: All clear sealers will accentuate any nonuniformity in concrete color, texture, or finish.
