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.

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.
