Do Patio Pavers Need to be Sealed?
You’ve just had a beautiful new patio installed using natural stone or concrete pavers. This was a big investment and you want to make sure you keep your new outdoor space looking its best. But do those patio pavers really need to be sealed? To understand if sealing is right for your situation, let’s first get familiar with patio pavers and their properties.
Patio Pavers Basics
Patio pavers are flat stone or concrete pieces used to create a patio surface. They come in various materials like natural stone, concrete, clay, or porcelain and are installed close together with small gaps between each piece. These gaps are usually filled with jointing sand or polymeric sand to lock the pavers in place.
Main Types of Patio Pavers
Some common paver materials include:
- Concrete pavers: Durable and affordable, available in various colors and finishes. Needs to cure for 28 days before sealing.
- Natural stone pavers: Options like granite, limestone, or slate are more expensive but very durable and beautiful. Requires sealing to protect against stains.
- Porcelain pavers: Extremely durable and stain-resistant, resembling natural stone. Ideal for high-traffic areas.
- Clay pavers: Adds character but is more porous and susceptible to cracking if not installed correctly.
Pavers Benefits
Patio pavers provide many advantages for outdoor living areas:
- Low maintenance: Don’t require as much upkeep as poured concrete, and weeding between pavers is easier.
- Drainage: Water flows between pavers instead of pooling, reducing the chance of slipping.
- Installation flexibility: Pavers can be removed and rearranged more easily than poured concrete if desired.
- Variety of styles: Wide selection of colors, shapes, and textures to match any outdoor design.
- Increased property value: Pavers enhance curb appeal and expand outdoor living space.
Why Sealing Patio Pavers?
Sealing patio pavers involves applying a protective sealer to the surface, forming a barrier that protects the pavers from internal and external damage over time.
Sealing prevents water, oil, dirt, and other stains from being absorbed into porous pavers, especially natural stones. It also offers protection against UV rays, weathering, and de-icing chemicals. Properly sealed pavers are easier to clean, maintain their colors longer, and are less prone to freeze-thaw damage, extending the lifespan of your patio.
Types of Sealers
- Acrylic sealers: An inexpensive spray-on option providing water and light stain protection. Easy to apply but may need reapplication more frequently.
- Silicone sealers: Forms a glossy, durable barrier that repels water. Can last 5+ years with regular resealing, though it may alter some surfaces’ natural look.
- Polyurethane sealers: Offers maximum protection against chemicals, petroleum products, and UV rays. Very durable, lasting 7-12 years with proper application.
Reasons to Seal Patio Pavers
Aesthetic Appearance
Sealed pavers retain vivid colors and clean lines longer. Unsealed pavers can fade, look dull, or develop incomplete coloring from wear.
Prolonging The Life
The sealer acts as an armor against degrading elements like chemicals, soil deposits, de-icing salts, and UV rays, preserving pavers for decades.
Protection Against Damages
Sealed surfaces resist spills from wine, coffee, or food without absorption, making cleaning simple.
Resistance To Weather Elements
Sealing enhances durability against freeze-thaw cycles, rain runoff erosion, and air pollution, allowing pavers to endure harsh seasons with minimal wear.
Protect Natural Color
Sealing creates a barrier that protects color pigments from weathering and wear, keeping shades vibrant longer.
What Happens If Pavers Are Not Sealed?
If pavers are not sealed, issues like the following may occur:
- Fading from UV exposure
- Difficult stains from spills absorbed into the pores
- Dull, worn appearance from dirt buildup
- Cracking or edge damage from moisture and freeze/thaw action
- Growth of moss, algae, or organic matter in joints
- Efflorescence deposits (white haze from minerals brought to the surface by moisture)
When Sealing Is Not Necessary?
In some cases, sealing may not be needed:
- Non-porous pavers: Durable materials like porcelain or some clay pavers have impervious surfaces that don’t need sealing.
- Minimal patio use: Low-traffic areas may not require a sealer’s protective qualities.
- Aesthetic preference: Some prefer the natural matte look of unsealed pavers.
- Climate factors: In consistently dry climates, pavers may not absorb much water.
Professional Vs DIY Patio Paver Sealing
Here are some pros and cons of each approach:
- Professional Pros: Even coverage, expert product selection, smooth application, potential warranty, less risk of incompatibility.
- Professional Cons: Higher initial costs than DIY.
- DIY Pros: Saves on labor costs, allows flexibility on schedule.
- DIY Cons: Requires supplies, risk of uneven coverage, greater learning curve.
Pro Tip: Consider project size, expertise level, product costs, and warranty value to decide if professional help will save you stress and deliver better results. For large patios, hiring a pro is often worthwhile.
