SUNDEK Sun Deck Coatings: Complete Guide
Your concrete patio cracks. The pool deck burns bare feet on summer days. That once smooth surface now looks dated and worn.
Replacing concrete costs thousands and takes weeks. But there’s another option most contractors don’t mention first.
SUNDEK coatings restore and protect concrete surfaces without demolition. These spray-applied systems cover damage, reduce heat, and add color in just days. They’ve been around for 50 years, yet many homeowners have never heard of them.
This guide explains what SUNDEK is, how different products compare, and whether professional installation is worth the cost. You’ll also learn maintenance tips that extend your sun deck’s life by years.
What Does “Sun Deck” Mean?
The term “sun deck” refers to an outdoor deck surface exposed to direct sunlight, such as rooftop terraces, pool areas, patios, or balconies. These surfaces are exposed to constant sun, water damage, and wear from foot traffic.
SUNDEK is a concrete coating company specializing in resurfacing and protecting sun decks.
Founded over 50 years ago, SUNDEK applies decorative overlays and protective coatings to existing concrete without replacement.
What is the SUNDEK Concrete System?
SUNDEK has specialized in decorative concrete coatings for over 50 years. The company started in California and now operates through licensed contractors across North America.
What Makes SUNDEK Different:
- Spray-applied acrylic and polymer-based coatings
- Covers existing concrete without removal or replacement
- Multiple texture and color options available
- Professional installation by certified contractors
- Proven durability in residential and commercial settings
The SUNDEK system works by bonding a polymer coating directly to prepared concrete. Contractors spray or trowel the material onto your sun deck surface, creating a new waterproof layer.
This layer hides cracks, stains, and surface damage while adding color and texture. The result is a refreshed outdoor space that resists water, sun damage, and daily wear and tear. Most installations take just a few days from start to finish.
Benefits of Using SUNDEK on Your Sun Deck
Choosing the right coating system makes a huge difference in how your sun deck performs. Here’s why SUNDEK stands out for outdoor surfaces.
- Slip Resistance & Safety for Pool Areas: The textured finish provides excellent grip even when wet, reducing falls around pools and water features.
- Heat Reflectivity and Cooler Surface: SUNDEK coatings reflect sunlight rather than absorb it, keeping surfaces up to 30% cooler than bare concrete on hot days.
- Customizable Design Options: You can choose from dozens of colors, patterns, and textures to match your home’s style and personal taste.
- Long-Term Performance and UV Resistance: UV-stabilized formulas prevent fading and breakdown from sun exposure, maintaining appearance for years without major repairs.
- Low Maintenance Considerations: A sealed SUNDEK surface only needs regular sweeping and occasional pressure washing to look fresh and clean.

DIY vs Professional SUNDEK Installation
SUNDEK works best when installed by certified contractors who know the system. Here’s how professional installation compares to DIY attempts.
| Aspect | Certified SUNDEK Installer | DIY or Non-Certified |
|---|---|---|
| Experience | Trained in prep, mixing, and application | Learning from your project |
| Warranty | Full manufacturer warranty included | No warranty protection |
| Surface Prep | Professional grinding and crack repair | May skip critical steps |
| Materials | Authentic SUNDEK products | Unknown imitation products |
| Equipment | Commercial spray rigs for even coating | Basic tools, inconsistent results |
| Results | Consistent color and texture | Visible flaws and variations |
Why Certified Installers Matter: SUNDEK trains contractors in product chemistry, surface prep, and proper application. They bring commercial equipment and handle permits, codes, and insurance requirements.
What Certification Provides: You get material and labor warranties covering 3 to 5 years. Certified dealers fix installation problems at no extra cost and provide ongoing maintenance support.
Imitation Product Risks: Knockoff coatings lack proper UV stabilizers and bonding agents. They peel, fade, or crack quickly and offer no warranty or technical support.
How to Maintain and Extend the Life of Your SUNDEK Deck
Proper care extends the life of your SUNDEK sun deck by years. Here are the essential maintenance tasks to keep your surface looking fresh.
- Regular Sweeping (Weekly): Use a soft-bristle broom to remove dirt, leaves, and debris before they scratch the surface or cause stains.
- Pressure Washing (Monthly or As Needed): Clean with low pressure (1500 PSI maximum) and mild soap to remove grime without damaging the coating.
- Spot Cleaning (Immediately): Wipe up spills right away using water and mild detergent to prevent permanent staining.
- Resealing (Every 2-3 Years): Apply a thin coat of SUNDEK sealer to maintain water resistance and protect against UV damage.
- Crack Inspection (Twice Yearly): Check for new cracks, peeling edges, or damage so you can fix problems before they spread.
- Furniture Protection (Always): Place felt pads under chairs, tables, and planters to prevent scratches and finish wear.
- Avoid Harsh Chemicals (Always): Skip bleach, ammonia, and acid-based cleaners, which can break down the coating and cause discoloration.
- Professional Inspection (Every 5 Years): Have a certified installer evaluate your sun deck condition and recommend when recoating is needed.
Cost Breakdown and ROI of SUNDEK Concrete Coatings
Understanding costs helps you budget for your sun deck project. Here’s how SUNDEK pricing compares to other options.
| Factor | SUNDEK Coatings | Concrete Replacement | Pavers or Tile |
|---|---|---|---|
| Cost Per Sq Ft | $3-$8 | $8-$15 | $10-$25 |
| Install Time | 2-3 days | 1-2 weeks | 1-2 weeks |
| Disruption | Walk on in 24-48 hours | No use for 7-14 days | Moderate |
| Lifespan | 10-15 years | 20-30 years | 15-25 years |
| Repair Costs | $200-$500 | $2000+ | $300-$800 |
| Design Options | Unlimited colors/patterns | Limited unless stained | Limited by selection |
What Affects SUNDEK Pricing:
- Surface size (larger areas cost less per square foot)
- Concrete condition (major repairs add costs)
- Product type (Classic Texture versus SunStone)
- Design complexity (custom colors increase labor)
Value Comparison: SUNDEK costs about half as much as concrete replacement. A 500-square-foot pool deck costs $2,000-$4,000 for SUNDEK, versus $4,000-$7,500 for new concrete. You get updated looks without the time and expense of demolition.
How to Choose the Right SUNDEK Product?
Choosing the right SUNDEK coating depends on your sun deck location, budget, and use. For pool areas, go with Classic Texture or SunSplash for slip resistance and water protection.
If you want a decorative look, SunStone and SunStamp offer natural stone or stamped patterns. High-traffic areas like driveways need durable options such as SunStamp or SunEpoxy.
Consider your climate as well, since extreme heat or freeze-thaw cycles require UV-resistant, flexible formulas.
Budget matters as well: SunSplash and SunSand are economical choices, while SunEpoxy costs more but lasts longer. Talk to a certified SUNDEK installer about your specific needs.
They can assess your concrete condition, recommend the best product, and show you color and texture samples that match your home style.
The Bottom Line
A worn sun deck doesn’t mean you need to tear out concrete and start over. SUNDEK coatings offer a faster, more affordable way to refresh outdoor surfaces while providing lasting protection.
The right product depends on your space, budget, and how you use it. Classic Texture works great for pools. SunStamp adds curb appeal. Garage floors need SunEpoxy strength.
Work with certified installers who know the system. They bring warranties, the right equipment, and years of experience your project deserves.
