Non-Toxic Concrete Sealer For Bird Baths: A Comprehensive Guide


Bird baths are a wonderful way to invite birds into your garden, providing a sanctuary where our avian companions can drink, bathe, and frolic. However, ensuring the longevity of these beautiful features demands careful maintenance, with special attention to the right choice of sealant. This comprehensive guide will provide insight into the world of non-toxic concrete sealers for bird baths, their benefits, suitable product options, and the process of application.

The Importance of Non-Toxic Concrete Sealers

What is a Concrete Sealer?

In essence, a concrete sealer is a protective layer applied to the surface of concrete structures to prevent water absorption and damage from the elements. By virtue of concrete’s porous nature, it can absorb water, which over time can lead to cracking and weakening. When applied correctly, a concrete sealer forms a barrier that prevents such damage, ensuring that your bird bath remains in top condition for many years to come.

Why Opt for Non-Toxic Sealers?

While a variety of concrete sealers are available in the market, not all are ideal for bird baths. Some sealers contain Volatile Organic Compounds (VOCs) or other toxic substances that could prove harmful to birds. Non-toxic concrete sealers, on the other hand, are safe for the birds, ensuring that your bird bath remains a healthful oasis for your feathered visitors. Plus, these non-toxic sealers also carry an environmental advantage, being more eco-friendly than their toxic counterparts.

Non-Toxic Concrete Sealer Options

Having established the significance of non-toxic sealers, let’s explore some suitable product options that guarantee both effectiveness and safety.

Gorilla Waterproof Clear Patch & Seal Spray

Gorilla Waterproof Clear Patch & Seal Spray is a wonderful choice for bird baths that feature paintwork. The product not only protects the underlying concrete from water and UV damage, but it also preserves the vibrancy of the paint, keeping your bird bath as colorful and inviting as ever.

Krylon UV-Resistant Clear Gloss Spray Can

Another excellent alternative for painted bird baths is Krylon’s UV-Resistant Clear Gloss Spray Can. Besides safeguarding your bird bath against water damage, this sealer offers additional protection against sun damage, thereby preventing fading and preserving your bird bath’s aesthetic appeal.

Gorilla Waterproof Patch & Seal Liquid

If you’re seeking a direct application to a concrete bird bath, consider Gorilla Waterproof Patch & Seal Liquid. This sealer provides a robust layer of protection against water damage and extends the lifespan of your bird bath.

How to Seal Your Bird Bath

While the thought of sealing your bird bath might sound daunting, it’s relatively straightforward when you follow these steps:


Start by thoroughly cleaning your bird bath. Remove all debris, water, and dirt, ensuring a clean surface to which the sealer can adhere effectively.

First Application

Spray your chosen sealer evenly across the entire bird bath, ensuring that every area, including small crevices, is covered. Let the first coat cure for about an hour before moving to the next step.

Second Application

Apply a second layer of the sealer, following the same process. Again, give it time to cure for an hour.

Final Topcoat

With the first two layers cured and hardened, you’re ready to apply the third and final topcoat. This layer seals the deal, offering your bird bath maximum protection.


The most challenging part of this process is probably the waiting. Once the final topcoat is applied, let it cure for a few days. During this period, avoid adding water or exposing the bird bath to natural elements.

Wrapping Up

Maintaining a bird bath extends beyond regular cleaning; it also involves protecting the structure itself. Non-toxic concrete sealers offer an excellent way to ensure the longevity of your bird bath, keep it visually appealing, and more importantly, guarantee a safe and enjoyable environment for birds.

Whether you opt for Gorilla Waterproof Clear Patch & Seal Spray, Krylon UV-Resistant Clear Gloss Spray Can, or Gorilla Waterproof Patch & Seal Liquid, you’re making a choice that benefits both your garden’s aesthetic and the well-being of its feathered visitors. So, ready your bird bath for the ultimate makeover and prepare to welcome an influx of colorful guests into your garden!


  1. Can I use other types of non-toxic sealers?

Yes, besides the mentioned ones, other sealers like tung oil, a natural, food-grade compound safe for concrete and stone birdbaths, can also be used. However, avoid using acrylic sealants and shellac as they don’t hold up well to water.

  1. How many coats of sealer should I apply?

Typically, 2-3 coats of sealer should suffice. Let each coat dry for at least an hour before applying the next one.

  1. How do I clean my bird bath?

For disinfecting your bird bath, opt for food-grade hydrogen peroxide or borax. Avoid using vinegar as it can damage the sealant.

  1. What factors should I consider when choosing a non-toxic concrete sealer?

Look for sealers explicitly labeled as non-toxic and safe for birds. Ensure that the sealer is waterproof, UV-resistant, and designed for outdoor use. Always adhere to the manufacturer’s instructions for application and curing times.


In the world of birding, bird baths play a crucial role, offering our feathery friends a place to rest, drink, and bathe. They also add charm and life to our gardens, creating an enchanting atmosphere as they attract a variety of bird species. However, to maintain these features in peak condition and ensure they remain a safe haven for birds, using a non-toxic concrete sealer is of paramount importance.
