All that we can offer of our knowledge, for your knowledge

We at Sealing Specialists are dedicated to informing the customer of everything there is to know about their pavers. In this way we are not only separating ourselves from other companies that dont divulge “industry secrets” we are assisting our customers in the maintenance of their surface for your benefit. It has taken many years in the industry to accumulate this knowledge and we compile it here and pass it to you freely.

paversearch-logoPerhaps the most cumulative and in depth source for paver information comes from paversearch. Here you can find out what type of paver or concrete surface you have and information ranging from cleaning specifics to installation instructions. This is an excellent resource for any curious or do it yourself home owner.

ure seal logoAt Sealing Specialists, we use Ure-Seal H20 for all concrete and paver sealing jobs we perform in Orlando, Florida. Ure-Seal H20, a state-of-the-art sealing product from Innovative Concrete Technology Corp., is a clear, water-reducible urethane sealer with a high-performance coating that can be used both indoors and outdoors.

pavers in OrlandoSeveral times on this site we mention efflorescence and many people have asked to know more. The most comprehensive and succinct article that we have found is hosted by a chemical stain removing company named Aldon. Though we don’t use Aldon products, we use an organic based efflo remover manufactured by Seal’NLock, they have created an excellent description of what it is, where it comes from, and how to remove it.

information on pavingRust is also a common stain found of pavers. hosts a very well compiled description of where rust can come from in regards to concrete and what to do about it.

algae on pavementIt is very difficult to find unbiased information on algae that focuses on its origins and growth habits in relation to concrete. Algae comes in many different forms and from many different places. Most commonly found on porous concrete is a green or black fungal algae. This type of algae can be carried to the surface by many sources but most commonly by water that has overflowed from plant beds or other fungal inhabiting places including flower pots, grass, gutters and other drainage. The algae grows because the conditions in the weather, especially in Florida, and on the surface are favorable, meaning consistent exposure times to sun and moisture. Removal of algae is often quite simple, it can be killed quite easily by chemicals ranging from vinegar to the most effective, chlorine. It is important to note that after spraying chlorine or any other algaecide onto any surface the algae itself is not removed. Though the color of the algae may be bleached out and become nearly invisible the dead remains of the fungus persist until it has been properly removed either by wiping or pressure spraying off. By skipping this process the surface will see a return of algae much quicker and if paint or sealant is applied it will not adhere properly.

geoarticlesBelow is an article that I have personally written informing people of the advantages of Seal’NLock over traditional Solvent based products. I have submitted it to and have posted it here for convenience.

I have been sealing pavers, concrete, and other stone in Central Florida for over 5 years using solvent (oil) based products. I was initially skeptical when I became aware of an innovative new water-based product on the market that claimed to possess the advantages of both water and solvent based sealants and none of the disadvantages. Though it sounded too good to be true I took a chance and decided to give it a try. It is now my belief that Sealnlock is undoubtedly the most revolutionary product to ever hit the sealing market.

Solvent based sealers require a completely dry surface before application to ensure full penetration of the pavers. This is because oil and water do not mix. Sealnlock is a water based product that is mixed with water prior to application. With water as the base, it allows the entire surface to be damp when the sealant is applied; this permits the entire job to be completed in only one day. The benefits don’t end there. Water based also means that the sealant is flooded over the surface, deeply penetrating the entire paver and all sand in the joints as it dries. Sealnlock also lasts longer than oil based products because of its revolutionary polyurethane mix which guarantees that water will bead on the surface for 2 years after application. Personally, I’ve done many solvent based jobs where I have returned after as little as 3 months to see that water gets soaked into the paver, resulting in color change, a sure sign the sealant has already started to degrade.

Solvent based products have also been considered superior due to their resistance to clouding. Clouding is when the bond between the sealant and the paver is weakened and the sealant turns into a filmy white coat over the paver. Here in Florida there is another factor besides sealant that can lead to clouding. The intense Florida sun heats up sealed surfaces and the perhaps more intense Florida humidity penetrates the heated, tacky sealant, causing it to turn cloudy because of its oil based nature. Sealnlock’s revolutionary formula guarantees no clouding, ever!

Another misnomer of solvent based superiority is the opinion that it helps to prevent against the appearance of efflorescence, or natural salts such as calcium, rust, mold, mildew, and algae. These surface destroying elements often come from underneath the surface where the paver, bedding, and ground beneath often harbor them. Because of the subpar protected joints these elements can come through the joint sand and leak over the surface ruining the sealant and the surface. Sealnlock penetrates all pavers and joints completely; virtually eliminating the appearance of paver destroying elements.

Solvent based products also have a very high VOC (volatile organic compounds) rating, reaching as high as 600 grams per liter. This is 3 times the EPA approved level. After working with this highly toxic product for years I am especially excited to announce that Sealnlock has a VOC rating of only 50 grams per liter, that’s 8% of the toxicity of solvent base. When solvent based sealers are applied to a surface they initially penetrate the surface and essentially coat the pavers in a thin layer of plastic. As the product wears away this plastic flakes off into tiny little pieces that runoff into storm drains and pollute our lakes and rivers. Seal’NLock not only adheres to every surface better and lasts longer; it will also more readily dissolve into water making it far less harmful. You and your family can feel safe knowing that you’re not subjecting yourselves to breathing in toxic substances or contributing to pollution of the water supply.

Sealnlock is an amazing product that has already taken the sealing industry’s top marks for its superior longer-lasting paver and joint penetration, guaranteed no clouding, better protection against the appearance of efflorescence, rust, mold, mildew, and algae, and the lowest VOC rating available. Solvent based products may provide an immediate beautiful look to your surface but the long term benefits of Sealnlock are undeniable.
