Breathable Siloxane Silane Sealers

Siloxane based masonry and brick sealers that are breathable and penetrate into the substrate have many advantages over other surface sealers comprised of acrylics, silicone and epoxies.

Siloxane Silane Water Repellent SealersAdvantages of Sealers:
A breathable sealer will help protect masonry and hardscape in many ways such as,

  • Resist cracking
  • Resist spalling
  • Reduce staining
  • Protects against UV damage
  • Prevents efflorescence
  • Prevent other damage related to water intrusion

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.

Siloxane Silane SealersPenetration 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.

 

TLC Supply offers several professional grade detergents and breathable siloxane/silane sealers from industry leading brands such as Prosoco and Mapei. TLC also carries a wide selection of premium pavers from Techo Bloc, GenestBelgard and Cambridge Pavers.

How to Prepare Pavers for the Fall and Prevent Leaf Stains

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

PreparePaversforFall

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.

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.

Efflorescence Causes, Removal, and Prevention

What is efflorescence?

EfflorescenceBrickEfflorescence is a crystalline deposit of salts (carbonates, sulfates, chlorides) that may appear as a chalky or white haze on surfaces of masonry, stucco or concrete.

The efflorescence  you are observing in your pavers is Calcium Carbonate, a by-product resulting from an interaction between the cement used to manufacture the paving stone and the natural environment, which includes the ground, the weather, and the atmosphere. In clay brick, the main component that can cause efflorescence is usually Sodium Chloride.

Efflorescence may appear soon after the pavers are installed or it could appear months after depending on several factors such as the climate, humidity, and the ingredients in the materials being used (such as cement, lime, pigments, and aggregate). When the stone is wet, you may notice that the efflorescence has disappeared but this is only due to water turning the efflorescence salts temporarily transparent rather than actually removing them. Once the surface dries, the efflorescence salts will re-appear.

EfflorenecePaversThere is no need to worry because your pavers and brick are not defective. Efflorescence is naturally occurring in cement based products and it will correct itself with time and exposure to the elements.

Why does efflorescence occur?

Concrete products contain cement which produces lime or water soluble calcium oxide. Since pavers have millions of microscopic capillaries, when moisture enters these capillaries it reacts with the calcium oxide and then calcium hydroxide is formed. This rises to the surface and reacts with carbon dioxide in the air and forms a white haze of calcium carbonate. When the moisture on the surface of the paver evaporates it leaves behind the white haze of efflorescence. Still curious about its formation?

How do you eliminate efflorescence?

As mentioned above, efflorescence is a naturally occurring phenomenon and it will correct itself with time and exposure to the natural elements.Since many factors are involved in the formation of efflorescence it is hard to determine when it will stop occurring. But if you would like to alleviate the problem quicker there are detergents available that can help clean and remove efflorescence. Another option to prevent efflorescence is to seal the pavers with a breathable sealant once the efflorescence is cleaned off.
