Attention Property Managers in Kansas City

Sunday, September 26th, 2010

If you manage a commercial property in Kansas City, you know that the American’s with Disabilities Act requires all public walkways to be clear of slip and fall hazards.  That means there can be no ice or damaged concrete that may cause an accident.  The only solution appears to be snow removal, sand, ice melt, and keeping your concrete in good condition.  Unfortunately though, the use of ice melt and other deicing salts can severely damage weak concrete.  Worse, in Kansas City, we have frequent freeze thaw cycles.  If you are using ice melt on the public areas of your property AND the temperature gets below freezing at night but warms up during the day, those are the absolute worst conditions for concrete.  When water enters unprotected concrete it expands and can cause micro cracks that weaken the surface.  Over time, if this happens frequently, the surface can begin developing deterioration in the forms of spalling and scaling.

Think of it this way, every time you use deicing salts and another freeze thaw cycle passes, it takes weeks off the potential life span of the concrete.  If you do not protect your concrete the probability of having to replace it sooner than if you did protect the concrete is substantially higher.  Maybe it is easier to think of it like gambling; you can let it ride and take your changes or you can hedge your bet. 

One thing is for sure, sealing concrete in Kansas City is the best thing any property manager can do to extend its useful life and postpone the cost of replacement. 

We seal concrete for apartment complexes, retail properties, maintenance provided managed communities, HOAs, and residential homeowners.

It is Concrete Sealing Time in Kansas City

Saturday, August 28th, 2010

When most people think of the September they think of back to school and football season but it is also the start of concrete sealing season.  For property owners that believe in prevention, September is the perfect time to seal concrete.  The temperatures start to cool down and there is plenty of time for penetrating concrete sealers to fully cure before winter. 

For more information about When is the Best Time of Year to Seal Concrete, visit our post on Merchant Circle.

At Sealwize, we typically like to break up our season into two parts.  The first part of the season we mostly work on decks and in the second part of the season we mostly focus on concrete.  We can be more efficient this way.  And through the years we have found that most homeowners prefer to wait on sealing concrete until the fall anyway.

We are ready for concrete sealing season in Kansas City.  We placed a big order for concrete sealant.  We have a good inventory of our less expensive water repellent sealer and our long-lasting, technologically advanced lithium silicate concrete hardner/densifier sealants

While our $0.50/ft promotion expires in September, we are still offering great deals for sealing concrete in Kansas City.  We offer discounts for online estimate requests and HOA groups.  If you are thinking about having your concrete driveway sealed, talk to your neighbor and see if they may also be interested.  If we can do more than one project in the same subdivision at the same time, we offer discounts.  The more people that participate the lower the price per foot for everyone.  Its a great deal for organized HOAs. 

If you are reading this post, you probably already know you need to seal concrete to keep it looking nice and extend its useful life.  But did you know that not all concrete sealers are created equal?  There are big differences in concrete sealant performance.  Some sealers perform better than other under different conditions.  Be particularily weary of slippery film-formers and penetrating concrete sealants based on sodium silicate technology.  We know that most of you don’t want to get into the details of why one concrete sealer is better than the other, but if you are interested, please call us at 913-575-1469.  We can explain the differences, pros and cons, of every type of concrete sealant and can share third party test results upon request.  Suffice it to say there is a reason why lithium silicate is the preferred choice of architects across the country.

We are ready for concrete sealing season and ready to help you keep your concrete driveway in good condition.  Please request an estimate online and we will follow up with you to schedule a consultation.  Or if you prefer, please call 913-575-1469. 

Thank you!

How Sealing Your Driveway Is Like A Vaccine…

Wednesday, 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.


Disclaimer – This article is written to help property owners understand the importance of sealing exterior concrete and is not intended as a literal comparison that implies complete prevention of surface deterioration is possible.  Sealwize of Kansas City cannot unequivocally guarantee concrete sealing treatments can prevent all concrete surface deterioration.  Although our Lithium-based concrete hardener/densifier is the best treatment for weak concrete, it cannot completely overcome problems associated with a poor concrete mix or poor finishing techniques.  We are unaware of any concrete treatment that can guarantee 100% prevention protection.

Concrete Driveway Sealing

Tuesday, 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

Saturday, 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
Volatile Organic Content: .2 lb/gal

Slip Resistance: Does not change surface friction coefficient


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.
