How to Prepare Pavers for the Fall and Prevent Leaf Stains

Treat and Prevent Unsightly Leaf Stains on Your Paving Stones this Fall!


As you may have noticed during autumn, once the leaves start falling they can leave behind leaf stains on concrete sidewalks. This staining can happen to your pavers too. Protect your hard earned investment and prevent those unsightly stains by sealing your paver patio, walkway, or driveway!

Why do leaves stain concrete?LeafStainonConcrete

Leaves and pine cones contain organic pigments that give them their color and when they decay they release a dye referred to as tannins. The word tannins originated from the German word for Oak tree and it was commonly used to tan leather. Tannins are also responsible for turning water brown when you steep a cup of tea. The staining from leaves occurs mainly in autumn when the leaves are decaying causing the tannins to react with the alkaline found in concrete.

How do you prevent leaf stains on concrete?

Sealing your pavers with a siloxane/silane sealant will help combat the staining. But bear in mind that not all sealers are created equal. Some sealants just create a film over the pavers and do not provide a breathable barrier for moisture to escape. We recommend choosing a water-based sealant with a siloxane/silane blend.

Why choose a silane/siloxane blend?

Siloxane based sealers penetrate deep into the capillaries of concrete pavers and brick. The chemical bond that the siloxane and silane creates inside the microscopic pores acts as a resin. It minimizes the sizes of the capillaries so that it is smaller than a water molecule which provides the repellency.

Penetration deep below the surface also means that your pavers will not lose protection if they are in a high traffic area. Sealers that sit on top on the paver can be eroded with heavy foot or vehicular traffic.

Siloxane/silane blends will also be 100% breathable. Concrete can absorb water 2 ways, from the surface and from the soil beneath it. These sealers will allow interior water to evaporate while also keeping surface water from penetrating into the paver. This is very important because sealers that do not allow the paver to breathe will trap moisture which can cause water to freeze and break the paver or brick during the colder months.

In conclusion,PreventLeafStainsonPavers

Sealing your pavers will act as a supplement to prevent the tannins from penetrating deep into the stone. You should take proactive measures to maintain your landscape by raking leaves before the pigments penetrate too far deep into the pores of the concrete and power wash stains whenever possible. The longer you keep the leaves on your patio to rot the harder it will be to remove the stains.

If it is too late and you need a detergent cleaner to help get those stains out we carry Paver Clean Paver Wash® by SRW.

Creating curb appeal with hardscaping is a big investment so protect it the right way the first time by choosing high quality, professional grade sealers. When sealing your hardscape be sure to follow the manufacturer’s directions very carefully and wear protective clothing and eyewear.

Best Sand for Paver Joints

What is the best sand for paver joints?

This is a great question to ask because you want to maintain the durability and longevity of your newly installed pavers. Polymeric sand is a high-tech mix of graded sand and binders, specially formulated for the filling of narrow or wide joints when installing pavers, slabs or natural stones, or when replacing existing joints. Unlike conventional sand, it locks in place and remains stable. It softens when wet and firms up when dry to better resist soil movements.


Polymeric sand is the ideal choice for filling in the joint spaces between your pavers because it offers many advantages such as,

#1 Secures Pavers: Polymeric sand keeps your pavers locked in place while also remaining flexible. The composition of polymeric sand includes both a high-tech mixture of graded sands and polymer which allows it to remain solid and bonded but flexible enough to move during freeze/thaw cycles without shifting the pavers out of place.

#2 Weather Resistant: Polymeric sand can withstand high levels of moisture. Other traditional sand used for jointing cannot and will wash right out of the paver joints thus causing the pavers to pull apart. Polymeric sand solves this common issue because it is waterproof and is flexible enough to withstand the expansion and contraction that occurs with the change in seasons. This increases the longevity of your pavers and provides easy maintenance.

#3 Helps Prevent Weeds & Pests: Polymeric sand that is used to fill the joints prevents plant life from growing up in between the stones. In addition it helps prevent weeds from growing that are airborne because the seed cannot root itself into the solid composition of the sand.The sand also prevents ants from coming up between pavers and building nests.

Before you purchase polymeric sand, keep in mind that not all are created equally. We recommend using Alliance® Polymeric Sand for all your hardscape projects because of their meticulous attention to detail and commitment to providing the BEST performing polymeric sand and dust in the industry.

How to Build a Paver Patio!

Building a patio out of paving stones or “interlocking concrete pavers” can be a beautiful and valuable addition to your home and can offer a durable, low maintenance area for you and your family to enjoy. You may opt to hire a professional mason but with these 10 steps you can install a paver patio all on your own!

Here are 10 Steps to help you build your very own outdoor paver patio!

Step 1: Plan

Paver Patio, Rotundo PaversDetermine what kind of paver you would like to use for your patio. There are many paving stone manufacturer’s to choose from that offer pavers in many different shapes, colors, sizes, and cost.

Did You Know? TLC Supply carries only the highest quality pavers backed by a lifetime manufacturer’s guarantee.

During this stage you will also want to determine the size, length, and design of your patio. Next, calculate your square footage to determine how much material you will need by multiplying length by width. You may even prefer to make a pattern.Research your selected paver manufacturer to see what patterns you can make with their pavers. Some patterns will require more or less pavers. Call TLC Supply for help in determining the amount of pavers you may need.

Step 2: Prepare the area

Clear any plants, roots, large rocks, or existing material that may interfere with the patio or cause unevenness.

Step 3: Mark the area

String StakesUse chalk line to mark out the area and if you are doing a curved design you can use a garden hose to mark the shape you wish to take and trace with chalk or paint. Then drive stakes into the ground following your laid out sketch. Wrap string around the stakes to outline the perimeter of the patio. Be sure to keep the string level so that your patio will be leveled.

Tip: It is actually the law to call your local utility company or “Dig Safe” and have them identify any buried gas, water, or electrical lines before you start digging.

Step 4: Excavate

Measure the thickness of your paver then dig a depth of 6”-8” below the bottom of the paver. This excavation should also allow room so that the pavers end up being flush with the ground. To avoid puddling you will want to slightly slope the patio in one direction so water can run off.

Tip: You can lay boards across the area and use a level to help you determine the slope.

Step 5: Back Fill

Fill the sunken area with 4”-6” of base material such as ¾” dense grade. This will help provide a solid base and aid in proper water percolation into the soil.

Paver CompacterTip: Fill the area with dense grade in 2” increments and compact with a machine plate compacter. This will ensure that the material is tightly packed. Pour another 2” of dense grade and repeat the steps until everything is compacted evenly to a depth of about 6”.You can even spray the area with water to help keep the dust down when tampering.

Step 6: Sand

ScreedApply a 1”-2” layer of concrete sand over the dense grade and compact it.

Tip: We recommend concrete sand rather than mason sand because it will provide more stability and assist in water percolation.

Now lay down two pieces of round level piping and push it a little into the sand. Depending on the width of your patio you may need to use a longer or shorter pipe. Doing this is going to help ensure your base is level before applying the pavers. Now spread more sand to make sure it is flush with the pipe. You can use a 2 x 4 to screed the sand to a smooth surface. If you cut a 1 3⁄4-in.-deep notch at each end of the 2 x 4, you can rest the notches on the edge restraints while you pull the 2 x 4 across the sand. Once the area is leveled, gently remove the pipe and fill the void with sand and smooth the area out.

Step 7: Lay the Pavers

Start laying the pavers in your desired pattern. Keep the pavers close together and gently press them down with a rubber mallet. If a paver is uneven you can tap it down more into place. If a paver is too low you can add a little sand to the area and rest the paver on top. To better fit pieces you may need to use a wet saw or a paver guillotine to cut pieces to the desired measurement.

Step 8: Edging

Beast Paver EdgingAdd plastic edging to the sides to define the perimeter of the walkway and to hold the pavers in place. Hold the edging in place with spikes. We recommend B.E.A.S.T. Plastic Paver Edging for its strength and flexibility. B.E.A.S.T. edging comes in 8 ft. sections and can be nailed in with 10” or 12” spikes. This edging is also made from recycled material and it allows for the growth of vegetation.

So far you should have something that looks like this!


Step 9: Fill Paver Joints

Polymetric SandWhen you finish laying the pavers pour polymeric sand over the top and gently sweep the sand over the whole area to fill the joints. Tamper the top to ensure compaction. You may need to add more sand and fill the joints again. When the joints are compacted and filled you should sweep away any excess sand with a broom. We highly suggest lightly blowing over the area with a leaf blower to ensure that the sand is off the surface of the pavers (polymeric sand will harden when wet).  Then you will want to mist the patio with water to secure the sand and pavers.

Tip: We recommend using polymeric sand over mason sand because it contains binders that help maintain a firm bond between the pavers which in turn help to secure them in place.

Step 10: Touch Up

Paver PatioFill in any missing areas with topsoil or grass. The roots of the grass will grow through the holes in the edge restraint to further lock it in place. You also can also add cobble stones or paver edging and even plant flowers or shrubs for a finishing touch to your patio.

Tip: Decorate your patio with furniture or even add a pergola, an easy to assemble fire pit, or you can even veneer the front of a grill to create an outdoor kitchen! The possibilities are endless in your new outdoor living space. Fill it with things that make you and your family happy.

Recommended: We highly recommend sealing your pavers with a breathable sealer to help prevent any staining.
