Frequently Asked Questions

What surfaces should be sealed?
Exterior concrete (interior garage areas) in regions subject to freeze-thaw cycles should be sealed.  Concrete should also be sealed for specific purposes such as stain repellence, dust reduction, abrasion resistance, chemical resistance, or to maintain an attractive appearance.

How long does the sealer last?
This depends on the type of sealer that is use.  Because penetrating sealers, penetrate the surface, they will last longer and generally only wear away if the substrate itself wears.  In this instance, penetrating sealers may last up to 10 years.  Acrylic membrane sealers offer the shortest performance life of 1-3 years.  This performance would be based on traffic wear and environmental exposure.

When should a sealer be applied?
Most acrylic membrane sealers can be applied as soon as the new concrete has been placed and can withstand the weight of the installer.  Other penetrating sealers should only be applied after the concrete has fully cured for 28 days.  All sealers can be applied or reapplied after the concrete is 28 days old.  Generally, sealers should be applied when air and substrate
temperatures are between 50⁰F and 90⁰F.

What happens if my concrete is left unsealed?
Concrete, by nature and design, is porous material that readily absorbs liquids.  In freeze-thaw climates, the expansion of frozen penetrating liquids can destroy the surface of unsealed concrete.  Oil, salt, fertilizer, and household or automotive chemicals can also discolor and damage unsealed concrete.

Will the sealer protect my concrete slab from oil stains?
Any oil spilled on a sealed concrete surface should be cleaned up as quickly as possible.  Penetrating sealers, like siloxanes, remain porous and oils may still penetrate the surface and stain.  Acrylic membrane sealers fill surface pores but may be weakened by petroleum distillates and possible stain the surface.  For best performance, spills should be cleaned up directly or the use of a chemical resistant sealer such as an epoxy or polyurethane should be used.

Will the sealer lock in leaf stains?
Yes, any surface stains that are not cleaned prior to sealing will typically remain.  These stains may fade over time due to exposure to sunlight, but evidence of the stain will remain.

How do I clean the concrete prior to sealing?
All concrete surfaces should be cleaned prior to sealing.  Dust, dirt, airborne contaminates, and minor surface staining can be removed with recommended cleaners designed to clean concrete surfaces.  Typically, these cleaners are high pH chemicals that dissolve the very top surface of the concrete.  These cleaners are applied with a surface mop or simple spray equipment.  The surfaces are then scrubbed with a broom or brush to help dissolve the top surface.  After the surface has been scrubbed, it is rinsed off with water.  This can be done with a low-pressure garden hose or a high-pressure power washer.  If a high-pressure power washer is used, the concrete surface must dry for a minimum of 7-14 days so any water in the concrete pores has time to come to the surface and evaporate.  The use of cleaners that utilize soaps or surfactants is discouraged as these cleaners are more difficult to remove from a porous surface. In any case, recommendations on cleaners from the sealer manufacture should be followed for best performance.

How are sealers applied?
Most sealers can be applied using simple tools, such as paint rollers or low-pressure pump-up sprayers.  Care should be taken to use “solvent resistant” equipment if solvent-based sealers are being applied.  As a general guide, solvent-based sealers are best applied with sprayers (back rolling low spots or pooling areas) and water-based sealers are best applied by roller.  The nap of the roller will be dictated by the profile of the concrete surface, but a 3/8-inch nap roller cover is a good choice to use across a variety of surfaces.  Manufactures recommendations on application and coverage rates should always be followed for best
performance.

What if  blisters or bubbles form on the surface?
Typically, this problem occurs more often with solvent-based membrane forming sealers. But it can also happen with water-based membrane forming sealers as well.  Most commonly, this happens when the sealer is applied to a hot or warm concrete surface.  Concrete is porous and is filled with air.  When the concrete surface gets warm or hot, air in the pores “blows” out of it.  At this same time, the sealer surface is curing and forming a thin film. The air blowing out of the concrete makes a bubble or blister.  The best way to avoid this problem is apply the sealer in the morning prior to the concrete substrate heating up.

How long before I can drive on sealed concrete?
Temperature and humidity will drastically impact the time the sealed concrete can be placed back into service.  Cooler temperatures and higher humidity will extend the time needed for proper curing.  A normal summer day of mid 70⁰F, a range of 1-3 days for foot traffic and 3-7 days for vehicular traffic.

Will the sealer be slippery?
This will depend on the product that is used. Reactive penetrating sealers typically do not impact the concrete surface profile or traction.  If a membrane forming coating is applied, the concrete surface profile may be affected. The application of a membrane forming coating may require traction or anti-skid additives to maintain expected slip resistance.

Will the appearance of the concrete look different or change after it is sealed?
No, generally speaking, penetrating sealers will not alter the surface appearance of the concrete surface.  Concrete surfaces to be sealed with penetrating sealers should be 100% dry and free of moisture. Chemistries designed in penetrating sealers react with moisture and may cause surface appearance or darkening effects.  Rule of thumb is all concrete substrates to be sealed with a penetrating sealer should be void of moisture for at least 7 days.  Membrane sealers form a coating on the concrete surface and will alter the appearance of the surface.  The membrane sealers are designed to reflect or refract common sunlight.  This will alter the appearance from a matte to high gloss finish.  This appearance will enhance and intensify the surface appearance. 

Can a sealer be applied over an existing sealer?
All sealers will wear over time.  Membrane forming sealers tend to wear more quickly, and require sooner attention.  There are several ways one can tell when it is time to reseal.  If the surface has lost its sheen, the surface soaks up water rather than beading on the surface, or the surface is showing signs of wear.  If any of these signs are recognized, its time to reseal.  It is always recommended to seal with the same material that was previously used to seal the surface.  Previously sealed surfaces should be cleaned with a mild soap and water.  This is to remove any surface contaminates that will inhibit proper adhesion of the new sealer.  If a penetrating sealer was previously used, similar penetrating sealers or solvent-based membrane forming sealer can be used (water-based membrane acrylic sealers will not penetrate the treated surface of previously treated penetrating sealer application). They will form a film on the surface and flake off.  This application is not recommended. If a membrane forming water-based sealer was previously used, similar water-based materials can be used. Penetrating sealers are ineffective and solvent-based sealers are to be used with caution as they can soften or eat away the previously applied
water-based sealer. For best performance, it is recommended that all previous coating is removed if the material or technology is not known.

Can sealers be left in a frozen or freezing environment prior to application?
Due to various chemistries used in manufacturing sealers, it is best to store and maintain sealers in an environment between 50⁰F and 90⁰F.

How much do sealers cost?
Sealers are quite cheap compared to the alternative of replacement of failing or damaged concrete.  Membrane sealers and chemically reactive penetrating sealers typically cost $0.15 to $0.25 per square foot and can be applied with easy to use equipment. Compare this to the full replacement cost of an average concrete slab ($9-$11 per square foot).

What is the warranty?
All ProSpec® sealers are warrantied to be free of contamination and defect in unopened containers.  It is the responsibility of the applicator to apply in a way that reflects the desired final performance and appearance.  No other warranties are expressed or implied.
