(Depth Of Grind)


Grade A

Grade A is a light abrasion of the surface to slightly smooth it out and prep for the sealer.

This depth of grind is typically paired with waterbased or solvent based sealers.  

Grade B

Grade B depth of grind, is considered a Light Aggregate exposure.  In the industry this is known as a Salt n Pepper grind.  This is because the tiny aggregate exposure resembles salt and pepper in size.  This is a very popular option as its uniformity is pleasing to the eye.    

This depth of grind can be paired with any type of coating or sealer.     

Grade C

Grade C depth of grind is considered medium Aggregate exposure.  This is very popular because it has a mix of larger aggregate with the salt n pepper.  And the surface is flatter than Grade B.  Often times this takes care of more surface blemishes due to the deeper grind. 

This depth of grind can be paired with any type of coating or sealer.     

Grade D

Grade D depth of grind is considered a Large Aggregate exposure.  This option requires a substantial amount of grinding and will bring the highest per square foot price.  It is however very popular due to the decorative nature of the aggregate itself.  Large aggregate exposures typically reveal up to 1" rocks in you slab.  As you can see it is quite beautiful!  

This depth of grind can be paired with any type of coating or sealer.     

Sealers & Coatings

There are a myriad of different sealers and coatings on the market and we can and will install any of them.  With that said, here you will find four options that we recommend .  If you have a different product in mind please feel free to discuss that with your Big City sales representative!

Grind & Seal

Design Options



There are many types of densifyer/hardeners on the market.  One of the most popular options is Ashford Formula.  Ashford Formula will chemically react to dustproof and harden a concrete floor for 30 years or more.  This improves the concrete more and more overtime.  It builds a crystalline reaction within the slab which will also aid in the overall sheen of the floor overtime.  This is a great option for somebody who just wants their concrete protected and performing at its best!

Acrylic Sealers

Acrylic Sealers have come along way since they hit the market.  They are low VOC water-based polymer emulsions, meaning they are UV stable and they are safe to breathe while applying.  They are non-toxic and typically have a low odor.  They also cure quickly.  Which makes for an easy install at a great price!  They are offered in matte, satin, and full gloss.  Often times they are coupled with a wax topcoat for better performance and easier maintenance.  



Urethane coatings are different from your densifiers and sealers.  They are a thicker mil product and thus have superior strength and durability.  They have a tenacious adhesion and will protect against both chemical spills and abrasion or scratching.  They are also UV stable and can be used alone or as a topcoat for a clear epoxy. They come in satin or high gloss finish.  And ask for SharkGrip if you'd like some extra traction!



Polyaspartic coatings are the creme de la creme of topical floor coatings.  They're UV stable.  They have a fast cure time and have superior hardness and abrasion resistance.  And they look terrific on a Grind N Seal.  But don't just take it from us, see what Concrete Network has to say about polyaspartics.  You can check Big City Surfaces out on Concrete Network too as one of their recommended contractors!
