For homeowners with concrete driveways and patios, deciding between using paint or a concrete sealer is a common debate. While paint has its own appeal and some benefits, concrete patio sealing is the safer and more durable option regardless of your goals.
Keep reading as we go over the main factors why you should consider sealing your concrete patio and what you should take into consideration before doing so.
What Is Concrete Patio Sealing?
Concrete patio sealing is the process of applying a specialized sealant that protects the concrete surface of your patio to greatly increase its longevity, as well as its visual and aesthetic appeal. Your patio will become water-resistant, helping moisture bead on the surface, and will resist the discoloration caused by UV exposure, making cleaning and maintenance much easier.
There are different types of concrete sealants homeowners can use depending on their desired look. Some result in a glossy protective film that forms a durable layer over the concrete surface—these are known as acrylic sealers or solvent-based acrylic sealers. Others “sink” into the concrete, offering a more natural, matte finish through a penetrating sealer. You can even opt for a high gloss wet look using solvent-based sealers designed for outdoor exposure conditions.
A tinted concrete sealer can change the color of your patio without the drawbacks of paint, which tends to chip and fade over time. The process involves applying two thin coats until the desired tone is achieved, producing a more durable, UV-resistant, non-yellowing surface.
When applying sealer, the method depends on the type. Generally, solvent-based sealers are most effective when applied with a sprayer, while water-based sealers or water-based acrylic sealers perform best with a paint roller for a smooth finish. Always ensure the surface has been power washed and the concrete is fully cured before sealing.
Six Reasons Why You Should Seal Your Concrete Patio
1. Moisture Protection
The biggest advantage of concrete patio sealing is its moisture protection. Excess water is one of concrete’s biggest enemies due to its porous nature. Allowing moisture vapor to seep in can lead to freeze-thaw damage, spalling, or cracks in exterior concrete and interior concrete surfaces alike.
By applying the best concrete sealer, you create a protective layer that prevents deicing salts, rain, and runoff from penetrating your patio. This is especially important for exposed aggregate concrete, patio pavers, and concrete driveways that face regular outdoor use and vehicle traffic.
2. Protection from Discoloration and Staining
Sun exposure, UV light, and natural wear can cause your concrete patio to fade over time. A UV-resistant concrete sealer prevents discoloration and protects against stains from food, drinks, and organic material. Many homeowners use sealant to protect against accidental spills from grills, planters, or pets.
Concrete sealers also help maintain property value by preventing permanent concrete stains. When properly applied, foundation armor sealants, epoxy coatings, or stone sealer products enhance durability while keeping your concrete’s color vibrant under all lighting conditions.
3. Protection Against Cracks
The combined effects of moisture, climate, and daily use can cause cracks in your concrete patio. Once cracks appear, they expand with time, especially if not properly treated. By applying sealer to new concrete, you can prevent cracks from forming and extend the surface’s lifespan.
Penetrating sealers and solvent-based acrylic sealers fill the pores of concrete, minimizing the risk of water infiltration and structural damage. This approach is effective on interior concrete floors, garage floor surfaces, and stamped concrete patios.
4. Extend the Longevity of Your Concrete Patio
Concrete is durable, but it still requires maintenance. Over time, unsealed concrete can develop surface film degradation, chipping, and discoloration. Applying a high-quality concrete floor sealer or epoxy coating ensures long-term protection from weather and chemicals.
Sealants form a barrier that protects your interior concrete floor and exterior concrete surfaces from wear. Water-based and solvent-based sealers both provide good protection, but solvent-based options often deliver a glossier appearance. Properly sealing your patio is like using sunscreen—it protects your concrete from premature aging and extends its usable life.
5. Match Your Home’s Style and Decoration
A sealed patio doesn’t have to be dull gray. With the right tinted concrete sealer or semi-transparent stain, you can achieve a cohesive design that complements your home’s aesthetic. Many homeowners use colored sealants or stamped concrete finishes to mimic natural stone or brick patterns, creating a natural look and smooth finish.
Whether you prefer a high gloss wet look or a matte finish, many concrete sealers today allow you to customize the tone and sheen. A protective film enhances your home’s décor while also ensuring the patio stays resilient under sun exposure and outdoor exposure conditions.
6. Ease of Maintenance and Cleaning
A sealed concrete patio resists dirt, mold, and grime, making cleaning much easier. Water beads on the surface instead of soaking in, which helps prevent mold growth and slippery conditions. If your patio has been previously sealed, applying sealer again periodically helps maintain a strong barrier and consistent appearance.
For interior concrete, like basements or enclosed porches, water-based acrylic products are ideal. For outdoor use, solvent-based products provide better resistance to hot tire pickup, deicing salts, and weather fluctuations. The general rule is to apply concrete sealer every few years, depending on your local climate and how much traffic the surface receives.
What to Consider Before Applying Sealant
Foot Traffic
Consider the level of foot traffic your patio receives. High-traffic areas like concrete pavers or driveways may require two thin coats for maximum durability. Regular maintenance with a new sealer ensures that even areas with heavy use maintain a natural finish and smooth surface.
Weather Conditions
Climate significantly impacts concrete performance. In areas with harsh winters or heavy rainfall, use non-yellowing, UV-resistant sealers that protect against moisture vapor and freeze-thaw damage. Most sealers on the market are designed for outdoor use, but always verify they’re compatible with your outdoor exposure conditions and vehicle traffic needs.
Personal Style
While sealers can add color, they primarily enhance the natural look of concrete. For homeowners wanting a natural finish, penetrating sealers are ideal. For those preferring a high gloss wet or semi-transparent aesthetic, solvent-based acrylic sealers or epoxy coatings can achieve that desired sheen.
Budgeting for Concrete Sealer Application
Sealers cost more upfront than paint, but the good protection they provide far outweighs the expense. A concrete patio sealed properly will require fewer touch-ups than one painted with a film-forming coating. The reduced maintenance cost, along with increased durability, makes applying sealer a sound investment.
Whether you have stamped concrete, exposed aggregate concrete, or standard concrete driveways, sealing is essential for maintaining both appearance and strength. A properly sealed patio provides long-term resistance to moisture, deicing salts, and daily wear.
When you’re ready to apply concrete sealer, make sure your surface is power washed, fully cured, and clean. Apply two thin coats using a roller or spray for best results. Once complete, your patio will not only resist the elements but also achieve a natural, beautiful finish that enhances your entire outdoor space.
