How to Clean and Seal Driveways and Patio Stones in 5 Steps

Do you know how to clean and seal driveways and patio stones? Let the professionals at Gappsi show you the process!  

Complete Polymeric Sand and Sealer Application – Dix Hills NY

Gappsi cleaning and sealing season for driveways and patio stones has started!   Our first driveway is located in Dix Hills NY. Over 10 years ago Gappsi installed this granite paver driveway and now we are cleaning and sealing it.

STEP #1 Cleaning Driveways and Patio Stones

Step 1 Removing All Polymeric Sand and Debris from Paver Joints

First, we clean the granite pavers and remove most of the sand in between the joints.  Our new surface cleaners are also extractors. We wash the surface of the pavers and also remove the old polymeric sand.  Also, the debris that has collected underneath the joints is washed out.

This year Gappsi added a new pressure washing system. The machine is a high volume low-pressure hot water system.  The pressure washing system can go to 250 degrees Fahrenheit in hot water. It also comes with a soft wash system for areas where we don’t need pressure.

Our team started the process of cleaning the pavers. The driveway floor was pretty dirty so we completed a few passes starting with a turbo nozzle.  The initial process is to clean the stones, and then remove the old polymeric sand in between the joints.  This allows the new sand to be put in between the joints.  We are using 200 degrees Fahrenheit of hot water. 

STEP # 2 Removing Sand and Debris From Driveways and Patio Stones

In the second step, we will clean the entire area with the extractor surface cleaner that will remove any sitting material in between the stone joints.

STEP #3 Applying New Polymeric Sand

The third step in sealing the pavers is filling the joint space with new polymeric sand.  We are using white beige silica sand.  This sand will absorb the sealer and get extremely hard; harder than polymeric sand.   Using a vibratory compactor specifically made to vibrate sand into the joints.  The Poly sand must be vibrated into the joint, as we want the sand as tight as possible in the paver joint.  The rollers have white rubber rollers specifically made for these kinds of applications and will not scratch or mark the stones.

STEP #4 Sealing the Driveway Pavers and Patio Stones

Step #4 is the process of applying the sealer.  We mix urethane sealer part A and part B in combination with water in a two-to-one solution. We apply the sealer through sprayers flooding the joints.  This allows the sealer to penetrate the sand and absorb it deep down to get hard. Using a blower to move the extra sealer around, we prevent it from settling on top of the stones and further draining into the sand.  Since these are granite pavers, they won’t absorb much of the sealer, but the sand will get very very hard. 

Which Sealer is Right For Your Stones?

Gappsi uses several types of sealers different for each stone type from granite to marble, travertine, or concrete pavers. In addition, there are color enhancers or natural look sealers.  We apply the proper sealer to the different types of stone surfaces or materials based on what is needed. Each stone absorbs differently and each application is different. Whether there is a top coating sealer or a penetrating sealer depends on the customer selection.  Also, we offer suggestions for the type of material we are protecting or enhancing.

STEP #5 Slip Resistant System Application

Step-5 Applying Slip-Resistant Sealer with Mop Driveway and Patio Stone Sealing

Step #5 After the team has completed sealing the entire driveway we apply an anti-slip resistance that will be the final process adding one more coat.  This application is applied with a floor mop while the sealer is wet.  The two coats bond together and it adds texture to the surface preventing it from getting slippery. 

The sealing process takes 2 to 3 days to complete allowing time to dry.  We allow the sealer to harden and keep the cars off the paver for about a week. The driveway was designed with granite pavers that are an inch and a quarter thick.  The sealer needs to be hardened a little longer as a result of the paver size.  The sand in between the joints has absorbed all the sealer and it became very hard. The color of the driveway looks like the first day the pavers were installed. The sealer enhancer used brings back the natural original color of the stones. It does not have a shiny look, it is more of a color enhancer. We also used slip resistance mixed with the sealer, this gives better traction when walking on the stones.

This is the latest sealing project done by Gappsi. The original granite installation Gappsi completed was over 10 years ago and the stones were selected from the Gappsi Natural Stone and Porcelain Collection showroom

Gappsi provides restoration, cleaning, and sealing of all types of stones and surfaces installed on patios, driveways, and walkways installed outdoors as well as indoors.
