Oil and Stain Resistant Penetrating Sealer

Any exposed porous surface such a concrete, brick or natural stone is susceptible to staining and discoloration. This can come from water, oil, organic and food based substances. Those charge with keeping these surfaces clean and pristine often turn to clear sealers to provide protection and reduce maintenance costs. However when it comes to oil and stain resistance not all sealers are created equal. Many of the penetrating type sealers are silane /siloxane sealers (silicone based). These penetrating sealers are effective in sealing out water but do not protect against oil based stains from petroleum products or from fat grease Other types of sealers are “film forming sealers” and a provide glossy barrier on the top surface that can be slippery and yellow with age.

Sealing products utilizing fluoropolymer resins are entering the market and offering superior stain resistance properties compared to other treatments and are fast becoming the next generation of surface protectors. With a  fluoropolymer based penetrating sealer you get invisible, non slippery, long-lasting oil and water stain resistance. These products can be used on any interior or exterior concrete or masonry surfaces exposed to water, oil or other organic substances that are susceptible to staining or discoloration.

Using an Oil and Stain Resistant Penetrating Sealer

Most people have come into contact with a product that was made from a fluoropolymer. Teflon™ fluoropolymers which were developed in 1938 by DuPont. Teflon coatings are well known for their non stick, friction reducing properties. In the same way penetrating sealers utilizing fluoropolymer resins are characterized by a high resistance to oils and they repel airborne dirt, pollution, acid rain, mineral and salt corrosion.

Fluoropolymer based sealers penetrate into porous materials, creating a long-lasting barrier that “locks-out” oils, water and soil. This barrier forces liquids to bead up on the surface, allowing them to be picked up more easily, and preventing them from causing a stain. The penetrating sealer will not only provide improved chemical and oil resistance, but it will also prevent dusting, spalling and inhibit efflorescence.

Fluoropolymer sealers such as PEN55 are ideal for factories, refineries, warehouses, schools, hospitals, shopping malls, service stations, parking lots, plazas, garages , restaurants and BBQ dining areas and. anywhere porous hard surfaces need to appear clean and sanitary with a minimal amount of cleaning and maintenance.

      Hello Terry,

      Thank you for contacting CoverTec. I am just now seeing your email. If your driveway is concrete I recommend our CoverShield U140 sealer. If you have brick paver then I recommend our StrongSeal Wetlook sealer. Both products have very good oil and stain resistance. You should clean the surface before you seal. Use CoverClean HC or similar for oil removal. All our product ship free in the USA. For pricing please visit our online store at https://covertecproducts.com/product/covershield-u140-gloss/

      Hello Donalad,

      I recommend our StrongSeal Wetlook for your pavers. This product has good oil and stain resistance. Cost $235.5 gal and $106/2 gal kit.
      For 500 sq.ft I think 4 gals is plenty for 2 coats. Please contact the office at 754 223 2465 if you wish to purchase.

    It’s interesting to read that Fluoropolymer will actually penetrate into the surface allowing for a deep, long lasting seal that will protect it. It makes sense that this would be helpful for something like concrete, particularly a porous one, because you wouldn’t have to worry about how long it’d last, etc. Thanks for sharing; I want to have my garage redone and I think concrete sealing would be a great way to make it more usable and luxurious.
