Paver sealers play a crucial role in protecting and enhancing the beauty of brick pavers. However, it’s important to be aware of the potential dangers they may pose. There are two main types of paver sealers available in the market: solvent-based and water-based. The issue arises with solvent-based sealers, as they often contain volatile organic compounds (VOCs). These toxic compounds can have harmful effects on both the environment and human health. When these sealers are applied, VOCs are released into the air, contributing to air pollution. It’s crucial to choose a water-based sealer that’s free from VOCs, ensuring a safer and more environmentally friendly option. By being aware of the potential toxicity of paver sealers, you can make an informed decision and prioritize the well-being of both yourself and the environment.
What Is Paver Sealer Made Of?
The main component of solvent-based paver sealers is the acrylic polymer blend, which provides the desired protective and aesthetic properties to the sealer. These acrylic polymers are derived from synthetic resins and are chosen for their ability to form a durable and long-lasting film on the surface of the pavers.
These solvents are responsible for dissolving the polymer blend and allowing it to penetrate into the pores of the pavers.
To enhance the performance and appearance of the sealer, other additives may be included in the formulation. These additives can include UV inhibitors, which protect the paver surface from the damaging effects of sunlight, and anti-slip agents, which increase traction on the sealed surface.
The solid materials present in the sealer can vary depending on the desired thickness and appearance of the sealer. These solid materials can include fillers, pigments, and aggregates. Fillers are used to thicken the sealer and provide a smoother and more uniform finish. Pigments can be added to tint the sealer to a desired color, while aggregates can be included to create a textured or non-slip surface.
Water-based concrete sealers are an eco-friendly alternative to solvent-based sealers, as they contain lower levels of volatile organic compounds (VOCs). Not only does this make them safer for individuals handling the product, but it also minimizes the negative impact on the environment.
Is Water Based Concrete Sealer Toxic?
Water-based concrete sealers are generally considered less toxic compared to solvent-based sealers. These sealers have a lower level of volatile organic compounds (VOCs), which are harmful chemicals that evaporate at room temperature. By reducing VOC content, water-based sealers pose less risk to both the user and the environment.
VOCs found in solvent-based sealers can have various adverse health effects when inhaled or exposed to the skin. They can contribute to respiratory problems, eye and throat irritation, and nervous system disorders.
The reduced VOC content means fewer harmful chemicals are released into the air during application and curing. This not only reduces air pollution but also decreases the potential for contamination of nearby water sources.
Water-based sealers offer a high level of durability and protection, making them a popular choice for various concrete surfaces. They can help prevent moisture absorption, staining, and damage from weathering or UV exposure. Additionally, they can enhance the appearance of the concrete, providing a glossy or matte finish without the need for harsh chemicals.
Another advantage of water-based sealers is their ease of use and clean-up. Since they’re water-based, they can be easily diluted and applied with regular tools like brushes or rollers. Spills and accidents are less of a concern since water-based sealers can be cleaned up with water, rather than needing strong solvents or chemicals.
With lower VOC content, they’re safer for users and the environment, as they emit fewer harmful chemicals during application and curing.
One of the main disadvantages of sealing pavers is that it requires ongoing maintenance. After sealing, you’ll need to regularly reseal your pavers to keep them in optimal condition. This is especially true if you use a thinner sealant that may break down and develop a film over time. The frequency of resealing will depend on the material of the paver and the brand of the sealer used.
What Is the Problem With Sealing Pavers?
Sealing Pavers Con #2: It can alter the appearance of the pavers. Sealing pavers typically results in a glossy or semi-glossy finish. While this may enhance the color and give the pavers a fresh look, it may not be desirable for everyone. Additionally, the sealant may discolor or darken the pavers, which can be disappointing if you were aiming for a specific aesthetic.
One downside of sealing pavers is that the sealed surface can become slippery when wet. This can be a safety concern, especially if the pavers are located around a pool, hot tub, or other water feature. If safety is a priority, you may want to explore alternative options that provide better traction.
If moisture becomes trapped underneath the sealant, it can lead to mold, mildew, and other issues. This is particularly problematic in areas with high humidity or heavy rainfall. Proper preparation and application of the sealant is crucial to avoid this problem.
Sealing pavers requires purchasing the sealant, as well as any necessary tools or equipment for application. If you hire a professional to seal your pavers, this can add to the cost. Additionally, as mentioned earlier, resealing will need to be done periodically, so the expense is ongoing. Homeowners must weigh the benefits of sealing against the added expense to determine if it’s worth it for their specific situation.
It’s important to carefully evaluate these factors and consider your specific needs and priorities before making a decision.
