What is Opti-Seal?
Opti-Seal is a deep penetrating concrete sealer and preservation agent. It is a non-toxic solution made from 90% biobased material. It preserves the concrete surface by stopping the Alkali Silica Reaction (ASR) and sealing out further water damage.
How does Opti-Seal work?
Once Opti-Seal is sprayed onto the concrete surface, it can penetrate up to 4 inches over time and provide an effective seal. The patented chemistry makes use of green nano-polymers, allowing for this deep penetration, and puts a stop to ASR degradation within the concrete.
What is the cure time for Opti-Seal?
Opti-Seal requires at least 8 hours for a complete cure and penetration.
Will Opti-Seal damage the concrete mix?
No, Opti-Seal will not damage the concrete. In fact, the solution stops ASR in its tracks, as well as seals out any further water damage. It will also maintain the concrete strength and performance.
What weather conditions are necessary for Opti-Seal?
Opti-Seal is not weather dependent and can work in all climates but it must be applied on a dry surface.
Will Opti-Seal cause rusting or corrosion on rebar in reinforced concrete?
No, Opti-Seal will not cause corrosive damage. It will help prevent further rusting and corrosion on the rebar by creating a protective coating.
Why is Opti-Seal better than other concrete sealants?
Opti-Seal is a non-toxic, sustainable solution that penetrates the surface rather than sets on top. Conventional sealants are comprised of hazardous materials. It also stops ASR, which no other sealant can accomplish.
Can Opti-Seal save you money?
Absolutely! It sprays on fast to save time and labor, and it prevents further degradation while increasing the longevity of concrete surfaces. A longer lasting, stronger concrete surface will save more money in maintenance, repair or reconstruction in the long run.
When should Opti-Seal be applied? Opti-Seal should be applied on a dry concrete surface. It can be applied on new concrete but only after the expected cure time so the concrete is dry. Opti-Seal should not be applied on a wet surface. Also, Opti-Seal should not be applied if the concrete surface has undergone too much degradation.
Where can Opti-Seal be applied? Opti-Seal is safe on normal concrete, colored concrete and porous concrete. It can be applied on both horizontal and vertical applications without run-off.
How should Opti-Seal be applied? Opti-Seal uses the spray system designed by BioSpan. The solution should be applied at a rate of 0.050-0.060 gallons per square yard for concrete with little visible distress. As the levels of distress vary from one sample of concrete to another, the application rate should be adjusted.
Are there any special conditions necessary for application of Opti-Seal?
No, Opti-Seal is designed to work on all concrete surfaces, and it is not temperature dependent. The choice to use Opti-Seal depends on the distress condition of existing concrete. Do not apply Opti-Seal on a wet concrete surface.
How long does a typical application of Opti-Seal last for?
One application of Opti-Seal has a typical lifespan of 5-7 years.
Is Opti-Seal safe for the environment?
Yes, Opti-Seal is a patented, non-toxic solution that is safe for both the user and the environment. It uses sustainable material and green nano-polymer technology, rather than conventional concrete sealants that can be harmful to the environment.
What quantities of Opti-Seal can be shipped?
Totes and bulk, in either isotanks or tankers (6,400 gallons).
Are there any shipping restrictions on Opti-Seal?
There are, but only when shipping over water. Due to the restrictions placed on most chemicals by the United Nations, Opti-Seal is treated as a hazardous material when shipped over water, in the case that it should be spilled into an ocean. By the same standard, orange juice falls under this shipping compliance. However, when shipped over land in the Americas, it is not a hazardous material.
