Does Sealing Concrete Make it Slippery

Sealing concrete offers a multitude of benefits, extending its lifespan, enhancing resistance to stains and cracks, and improving aesthetics. However, a frequent concern arises – does sealing concrete make it slippery? While this can be a valid worry, the answer isn’t always a straightforward yes or no. This article will talk deeper about this topic, exploring the potential for slipperiness, uncovering common misconceptions, and providing practical safety tips to create a safe and beautiful concrete surface.

Benefits of Sealing Concrete

Sealing concrete surfaces offers several advantages, making it a popular choice among property owners.

Protection Against Stains and Chemicals

Sealing creates a protective barrier that prevents liquids, stains, and chemicals like oil, grease, and water from penetrating the surface. This significantly reduces the likelihood of unsightly stains, discoloration, and damage from harsh chemicals, preserving the aesthetic appeal and durability of your concrete. This benefit is particularly relevant for areas with high exposure to these elements, such as driveways, garages, and industrial floors.

Enhanced Durability

Sealing increases the durability and longevity of concrete. By sealing the surface, you are protecting it from harsh weather conditions, UV rays, and other environmental factors that can cause damage over time. This prolongs the lifespan of your concrete surfaces, saving you money on future repairs and replacements.

Easier Maintenance

Sealed concrete is much easier to clean and maintain compared to unsealed surfaces. The protective layer prevents dirt, grime, and other debris from embedding into the pores of the concrete, making it a breeze to clean with just soap and water. Additionally, sealed concrete is less prone to cracking and chipping, further reducing the need for maintenance.

Prevents Efflorescence

Sealing prevents efflorescence, a common problem with unsealed concrete, where mineral deposits form on the surface due to water vapor migrating through the concrete. Sealing creates a barrier that blocks moisture from penetrating the surface, thus reducing the occurrence of efflorescence.

Enhances Appearance

Sealed concrete surfaces have a more polished and professional appearance. The sealant can enhance the natural color of the concrete, giving it a glossy or matte finish, depending on your preference. This adds to the overall aesthetic appeal of the space, making it more inviting and visually pleasing.

Reduces Cracking and Spalling

Sealing concrete helps prevent cracking and spalling, which are common issues with unsealed surfaces. The sealant penetrates the pores of the concrete, filling any small cracks and preventing water from seeping in. This helps maintain the structural integrity of the concrete, prolonging its lifespan.

Common Misconceptions

Slippery Surfaces

One of the most widespread misconceptions about concrete sealing is that it makes the surface slippery. While certain sealers can alter the texture and potentially create a slippery surface, choosing the right type of sealer and applying it properly can ensure a safe, non-slip finish.

One-Time Process

Another misconception is that sealing is a one-time process. In reality, concrete surfaces should be resealed periodically, typically every 2-5 years depending on the sealer type and traffic conditions, to maintain their protective properties and optimal appearance.

Factors Affecting Slipperiness

Several factors influence the slipperiness of a sealed concrete surface:

  • Sealer Type: Glossy finishes can increase slipperiness, especially when wet. Opt for matte finishes or sealers with non-slip additives for better traction, particularly in high-traffic areas.
  • Surface Texture: Smooth surfaces are more prone to slipping, while textured surfaces like exposed aggregate provide better grip.
  • Application: A thin coat applied with a brush or broom creates a textured surface, while a thick coat from a roller or sprayer can become slippery.
  • Professional Application: Professionals can ensure proper application and reduce the risk of slipperiness by applying the right amount and creating a uniform texture.

Safety Tips to Minimize Slipperiness

While choosing the right sealer and application methods are crucial, here are some additional safety tips to minimize the risk of slipping on sealed concrete:

  • Use Non-Slip Mats: Placing non-slip mats or rugs at entrances and exits, especially in areas prone to moisture like pool decks and around bathtubs, can provide additional traction.
  • Maintain Cleanliness: Regularly cleaning the surface removes dirt, debris, and algae that can contribute to slipperiness, especially after rain or snow.
  • Re-apply Sealer Regularly: Over time, sealers can wear down, reducing their effectiveness and potentially increasing the risk of slipping. Re-applying the sealer periodically, as recommended by the manufacturer, helps maintain optimal slip resistance.
  • Install Proper Drainage: To avoid water pooling on the surface, which can increase the risk of slipping, proper drainage installation is recommended.
  • Post Caution Signs: In areas where the potential for slipperiness is higher, consider posting caution signs to alert pedestrians and visitors. 
  • Add Lighting: Consider adding lighting to illuminate walkways and entryways, especially in areas with low light conditions.
  • Choose Appropriate Footwear: When walking on potentially slippery surfaces, wear shoes with good tread patterns that provide traction. Avoid smooth-soled shoes that can easily slip.


By understanding the factors affecting slipperiness and following the safety tips provided, you can enjoy the numerous benefits of sealed concrete while minimizing the risk of slips and falls. Remember, consulting with a professional, like Ener-Spray, can ensure the right sealer and application method are chosen for your specific needs and desired aesthetic, creating a beautiful and safe concrete surface for years to come.
