Review OLYMPIC Waterguard Oz. Clear Exterior Waterproofing Wood Sealer Spray
The **Olympic 00477272 WaterGuard Exterior Wood Sealer Spray** is a high-performance, water-based formulation designed to provide superior protection for exterior wood surfaces while enhancing their natural beauty. Engineered for durability and ease of application, this advanced sealer creates a transparent, breathable barrier that shields wood from moisture, UV rays, and environmental wear, ensuring long-lasting defense against rain, snow, and humidity. Ideal for decks, fences, siding, and outdoor furniture, this product penetrates deep into the wood fibers to form a resilient shield that prevents swelling, warping, and rot while maintaining the grain s natural texture. Unlike traditional oil-based sealers, WaterGuard is low in volatile organic compounds (VOCs), making it safer for both users and the environment, and it dries quickly to minimize application interruptions. Its non-yellowing formula preserves the wood s original color, allowing subtle variations in hue to remain visible while providing a subtle sheen that enhances visual appeal. The spray application system ensures even coverage with minimal waste, making it a practical choice for both DIY enthusiasts and professional contractors tackling large or hard-to-reach surfaces. With a commitment to longevity, this sealer extends the lifespan of wood by resisting mold, mildew, and insect damage, making it an indispensable solution for maintaining the integrity and aesthetics of outdoor woodwork in all climates. Whether applied to freshly milled lumber or weathered surfaces, WaterGuard delivers consistent protection and a polished finish, ensuring that outdoor wood remains vibrant and structurally sound for years to come.
The **Olympic 00477272 WaterGuard Exterior Wood Sealer Spray** is a popular choice for protecting wood surfaces from moisture, rot, and weathering. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of Olympic 00477272 WaterGuard Exterior Wood Sealer Spray**
1. **Effective Waterproofing** The product forms a protective barrier against rain, snow, and humidity, preventing water absorption that can lead to swelling, warping, or rot. It is specifically designed for exterior wood surfaces like decks, fences, and siding.
2. **Easy Application** Comes in a spray format, which allows for quick and even coverage without brush marks or drips. This makes it ideal for large surfaces or hard-to-reach areas.
3. **Clear Finish** Maintains the natural appearance of the wood while providing protection. Unlike stained sealers, it does not alter the wood s color, making it a good choice for preserving the original look.
4. **Durability** Offers long-lasting protection (typically up to 12 months, depending on weather exposure). It resists UV rays to some extent, reducing fading caused by sun exposure.
5. **Low Odor** Compared to some other sealers, it has a relatively mild odor, making it more comfortable to use without heavy ventilation requirements.
6. **Versatile Use** Suitable for a variety of exterior wood surfaces, including decks, railings, fences, and outdoor furniture. It can also be used on previously sealed wood as a refresher coat.
7. **Quick Drying** Dries to the touch in about 1 2 hours, allowing for faster project completion compared to some thicker sealers.
8. **Non-Staining** Unlike oil-based sealers, it does not leave a sticky or yellowed residue over time.
9. **Eco-Friendly (Relative to Some Alternatives)** While not entirely non-toxic, it contains fewer harsh chemicals than some solvent-based sealers, making it a more environmentally friendly option.
10. **Good for Maintenance** Can be easily reapplied without extensive surface preparation, making it convenient for annual or bi-annual maintenance.

### **Cons of Olympic 00477272 WaterGuard Exterior Wood Sealer Spray**
1. **Limited UV Protection** While it provides some resistance to UV rays, it is not as effective as dedicated UV-blocking sealers or stains. Over time, prolonged sun exposure can still cause wood to fade or dry out.
2. **Not a Stain** If you want color enhancement or deeper protection against UV rays, this product does not provide that. It is purely a clear sealer, so it may not be sufficient for heavily exposed or high-traffic areas without additional staining.
3. **Requires Reapplication** Like all exterior sealers, it will eventually wear off, especially in harsh climates. Reapplication is necessary every 1 2 years to maintain full protection.
4. **Surface Preparation is Critical** For best results, the wood must be clean, dry, and free of mold, mildew, or peeling paint. Neglecting prep work can lead to poor adhesion and reduced effectiveness.
5. **Spray Application Can Be Messy** If not applied carefully, overspray can land on nearby surfaces (e.g., plants, siding, or concrete), requiring cleanup. A spray gun or extension wand can help mitigate this.
6. **Not Ideal for Porous Woods** Some woods, such as cedar or redwood, may absorb the sealer unevenly, leading to patchy protection. Pre-treatment or a primer may be needed for optimal results.
7. **Limited Mildew Resistance** While it provides some protection against moisture, it is not as effective as mildew-resistant sealers in humid or damp climates. A mildew-resistant additive may be needed in such cases.
8. **Cost per Coverage** For very large projects, the spray format can be more expensive than brush-on or roller-applied sealers, especially if multiple coats are required.
9. **Not Suitable for Interior Use** Designed exclusively for exterior applications. Using it indoors could lead to inadequate protection and potential damage from indoor humidity.
10. **May Not Seal Deeply Enough for Rotten Wood** If the wood is already damaged by rot or mold, this sealer will not reverse the damage. It is a preventative measure, not a restorative one.

### **Conclusion**
The **Olympic 00477272 WaterGuard Exterior Wood Sealer Spray** is a solid choice for homeowners looking to protect exterior wood surfaces from moisture and minor weathering. Its ease of application, clear finish, and effectiveness in preventing water damage make it a practical option for decks, fences, and outdoor furniture. However, its limitations such as lack of UV protection, mildew resistance, and the need for reapplication mean it may not be sufficient for all situations, particularly in harsh climates or for heavily exposed wood.
If your primary concern is waterproofing and you are willing to reapply it annually, this sealer is a good investment. For areas with intense sun exposure, high humidity, or existing wood damage, pairing it with a UV-blocking stain or a mildew-resistant additive would be advisable.
---
### **Recommendation**
- **Use it if:** You need a quick, easy-to-apply clear sealer for exterior wood that is primarily exposed to rain and humidity. It s ideal for maintenance projects where you want to preserve the wood s natural look without staining.
- **Avoid it if:** You require strong UV protection, mildew resistance, or a colored finish. In such cases, consider a **semi-transparent or solid stain** (e.g., Olympic s own stains or brands like Thompson s WaterSeal) that offers broader protection.
- **Best for:** Decks, fences, outdoor furniture, and siding in moderate climates where water damage is the main concern.
- **Pair with:** A **wood brightener or cleaner** before application and consider a **UV-protective topcoat** if the wood is heavily exposed to sunlight.
For long-term protection in harsh conditions, combining this sealer with a **stain or additional mildew-resistant treatment** would be the most effective approach. Always follow the manufacturer s instructions for application and reapplication intervals.
