Concrete Aggregate Sealers

Fast Finish provides the best protection for your concrete, natural stone, or hard surfaces.  We specialize in applying the best Solvent and Water based sealers available for almost any surface or condition.  These are not always available at your local box stores and exceed our expectations for protection and longevity. And as with all our finishes, we can clean and protect them to last a lifetime.

The most used sealers or coatings for Exposed aggregate surfaces are Silane/ Siloxane, Acrylics, Urethanes

`Silane-Siloxane sealers are impregnating sealers for concrete and masonry surfaces. It penetrates and chemically bonds deep within the substrate to form a hydrophobic barrier within the pores. A penetrating sealer is your best choice if your goal is to: Protect exterior concrete surfaces subject to corrosion and freeze-thaw damage. Obtain a natural, matte finish. Provide invisible protection without changing the surface appearance or leaving a sheen. Silane blends or silane sealers are great choices where the pore of the concrete or substrate are closed or tighter and the need for a smaller molecule is needed. Siloxane sealers are typically utilized more where the substrate material is more porus and the smaller molecule is not a concern. Silane / Siloxane sealers are both part of the silicone family of sealers and can be found in both a water based and solvent based formula.

 Penetrating silane-siloxane sealers, when properly balanced, allow water to bead on top of the substrate.

Penetrating siloxane sealers also allow interior water vapor to leave the brick or masonry substrate. This is an important difference between a surface sealer and many other penetrants. A surface sealer will keep interior water vapor that needs to escape inside the brick. In a cold climate, water vapor trapped behind a surface sealer will freeze and cause the brick to spall or flake.

                                              CHOOSING A SILANE/SILOXANE SEALER

Check for the following three characteristics when choosing a penetrating silane-siloxane sealer:
  • Water based. Water-based penetrating silane-siloxane sealers typically have lower VOCs, can be readily applied, are non-flammable, and are easy to clean up when application is complete.
  • Low VOC content. Penetrating sealers can vary from very high VOC (more than 400 grams per liter) to very low VOC (less than 100 grams per liter). Low VOCs are more user and environment friendly and are not considered dangerous or harmful.
  • Water repellant. Water should visibly bead, approximately 90°, on the surface where the product is applied.

NOTE: Other reactive penetrating sealers (silanes and siloxanes) and most high-performance coatings, such as epoxies and urethanes, should only be applied after the concrete is fully cured (generally 28 days). Almost all sealers can be applied after the concrete is 28 days old.

Average coverage rate is 100-200sq ft per gallon.


Best temperature range for application  is between 50 - 95 degrees Fahrenheit for water based sealers. 65-80 degrees for solvent types

50 degrees Fahrenheit on the low end (with no freezing that night) and no warmer than 95 degrees Fahrenheit on the high end.

How long does our sealers last? 

  •  As far as longevity of the sealer goes, in the first 3-5 years you'll have excellent protection, in the 5th-7th year you have good protection and after that you should have adequate protection. These are just general guidelines - many things will factor into how long it's expected to protect the concrete due to traffic wear.

 Sealer Information for Specific Concrete Surfaces

The Concrete Network has the most information regarding the different uses and applications of concrete sealers. This information is to help the client understand the different coatings that are utilized for their surface.

10 year sealer protection


Although one of the most durable materials,
concrete will begin deteriorating when
exposed to conditions like rainwater,
repeated melting and freezing and road salts
or de-icers. We've all seen (or experienced)
driveways that, within years, begin cracking,
scaling and spalling.
It’s a fact:
Concrete Deteriorates Over Time.
It doesn't need to be this way.
