  • Description

    Siloxa-Tek® 8510 is an advanced, high performance, industrial strength solvent based concrete/masonry water and oil repellent solution designed to reduce water and moisture intrusion. This unique formula incorporates leading molecular nanotechnology; putting an end to water, oils, fluids and moisture migration through any porous cementitious substrate. Siloxa-Tek® 8510 is a uniquely transparent, blended formula with added enzymes and surfactants that aide in accelerating a penetrating disbursement. Thus eliciting a more effective, uniformed reaction between the formula and the concrete / masonry substrate it’s being applied to. Siloxa-Tek® 8510 provides a hydrophobic barrier beneath the surface and seals out moisture while remaining highly vapor permeable and chemically bonding with the substrate. The treated surfaces will show no change in visual appearance from application and the surface that will not chip, flake, delaminate or breakdown with UV light exposure.

  • How It Works

    A water repellent impregnating sealer is a surface applied, invisible, non-film forming protection system, that can very effectively increase the durability of concrete. Due to the small size of the mono-molecular layer, there is little or no change in its aesthetic appearance. Compared to film forming coating systems, the surface applied water repellent impregnating sealer penetrates the surface pores and capillaries, so they are internally lined but not filled. Water repellent impregnating sealers change the surface tension of mineral substrates that produce a water repellent surface to keep water and aggressive water-soluble salts, such as chlorides and sulfates, out.

    In structures on and below grade water should generally be kept out and away to prevent damage. The most pervasive form of concrete damage is surface scaling from freeze-thaw. Other forms of damage include alkali-silica reaction (ASR), chemical intrusion and corrosion of steel reinforcements. Siloxa-Tek® 8510 can block up to 99% of surface moisture. The active ingredients seal the pores within the substrate adequately blocking surface moisture while still maintaining the concretes ability to breathe. It will not significantly modify substrate appearance or traction and will only wear away if the concrete surface itself wears away.

    New or existing concrete can be treated and performance can be improved in as little as two applications. Backed by a 100-year warranty, Siloxa-Tek® 8510 oil repellent sealer is a small investment that leads to long-term savings and improved performance.

  • Preparation

    Avoid contact with skin, eyes and clothing. Wash hands after use and do not take internally. Please refer to the product Safety Data Sheet (SDS) before using. The preparation process should be followed to ensure adequate penetration and optimum performance:

    Step 1: The concrete substrate must be structurally sound, thoroughly dry and clean. Wait at least 24-48 hours after rain and/or pressure washing before sealing; concrete should be visibly dry.

    Step 2: Remove all paints, previous sealers and/or adhesives before application.

    Step 3: The substrate must be clean of oil, grease, dirt, wax, curing compounds, efflorescence and other contaminants that might interfere with the penetration of the sealer.

    Step 4: If acid is used to clean the concrete, neutralize the surface completely and rinse it with water prior to application. Then wait for the concrete to dry out for at least 24-48 hours.

    Step 5: The surface-zone moisture content of the concrete should not exceed 4%wt.

    Step 6: Cover all surrounding areas not intended to be coated.

    Step 7: New concrete must be cured for at least 28 days before sealing.

  • Application

    Step 1: Siloxa-Tek® 8510 is ready to use right out of the container. Stir extremely well before use.

    Step 2: Pour the Siloxa-Tek® 8510 into a paint tray or bucket and dip a 3/8" nap roller into the tray or bucket.

    Step 3: Roll one coat onto an area of approximately 100 square feet.

    Step 4: Immediately apply a second coat to the same 100 square foot area, while the first coat is still wet. You may walk on the first coat to apply the second coat. Apply until the surface is saturated but not to the point of puddling. (Since the Siloxa-Tek® 8510 is a hydrophobic product if you try to apply a second coat after the first coat has dried, the first coat may try to repel the second coat).

    Step 5: Roll or broom out any puddles until the sealer penetrates the substrate.

    Step 6: After the first area has been treated move on to the next 100 square foot section and apply two (2) coats following the wet-on-wet application method.

    Step 7: When the entire application has been treated with two (2) coats, let the concrete dry for at least four (4) hours before walking, 24 hours before driving, and protect the concrete from rain for at least 24-48 hours after sealing.

    Step 8: Clean up: Application tools can be cleaned using mineral spirits.

    Step 9: Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

    Application Notes

    • Before application test the sealer by applying in an inconspicuous area to ensure the desired coverage and appearance is achieved.
    • Do not over apply.
    • Prevent from getting on glazed and finished surfaces such as glass, aluminum etc. In case of contact flush immediately with water.
    • Do not use on concrete that has been previously sealed without chemically etching or mechanically scarifying.
    • Water repellency may take up to seven (7) days to develop.
  • FAQ

    What does wet-on-wet mean? Wet-on-wet means that the second coat is applied while the first coat is still wet. Two coats of the Siloxa-Tek 8510 are required wet-on-wet. The second coat is applied immediately after the first coat while the first coat is still wet, since the Siloxa-Tek 8510 is a hydrophobic product it will try to repel the second coat if the second coat is applied after the first coat has dried.

    Can I walk on the first coat to apply the second coat? Yes, you can walk on the first coat to apply the second coat. Since the Siloxa-Tek 8510 is a penetrating sealer it will dry invisible and will not show footprints.

    Can I paint after sealing? In order to continue repelling oils and staining we do not recommend painting over the Siloxa-Tek 8510.

    Does the concrete need to be dry before sealing? Yes, the concrete needs to be as dry as possible before sealing. We recommend the moisture content of the concrete be less than 4%wt. It is recommended to wait at least 24-48 hours after rain and pressure washing before sealing.

    What is the difference between Siloxa-Tek 8505 and Siloxa-Tek 8510? The Siloxa-Tek 8505 is water based water, salt and oil repellent whereas the Siloxa-Tek 8510 is a solvent based water, salt and oil repellent.

    What can I use to apply this product? The Siloxa-Tek 8510 can be applied with a 3/8" nap paint roller or a brush.

    How do I get oil stains out of my concrete? We recommend a highly concentrated, oil busting dish soap, such as Dawn. Squirt it over the stain and spread it around to cover the entire affected area. Let it sit for about an hour, then mop up the dish soap and oil with a paper towel.

    Where can I buy this product? The Siloxa-Tek 8510 is available through a number of distributors found on our distributor page.
