2. Best Durable Coat for Countertops – General Finishes High Performance Topcoat

[amazon box=”B001DSZ3C8″ template=”horizontal” link_id=”4195″]

In my experience, General Finishes High-Performance Topcoat is an invaluable addition to the toolkit of any DIY enthusiast or woodworker. Its primary purpose is to provide top-tier protective finishes, especially for countertops.

One of the top-selling points of this topcoat is its exceptional durability. It ranks among the toughest consumer polyurethane topcoats, providing a robust shield against scratches and wear. This ensures that your finished projects can withstand the test of time.

Another stand out feature is its unique ability to resist yellowing, a common concern when applying clear topcoats over bright white or light-coloured paints. However, it’s worth noting that while this topcoat does an excellent job in minimizing the risk of yellowing, there may still be some degree of yellowing, depending on the substrate.

During my hands-on testing, I found the rapid drying time to be the most impressive feature. With a mere 1 to 2 hours needed between coats, it significantly speeds up project timelines, achieving a flawless finish in record time.

While General Finishes High-Performance Topcoat may not be the absolute fastest-drying option available, its remarkable resistance to yellowing, swift drying time, and unmatched durability make it a strong choice if you prioritize long-lasting quality and the longevity of your projects. It deserves its place as the second choice in the reviews.

3. Best Food-Safe Formulation – Rust Oleum Watco Butcher Block

[amazon box=”B000VITOT4″ template=”horizontal” link_id=”4194″]

Rust-Oleum polyurethane is a fantastic choice, especially when prioritising food safety in your woodworking projects. It’s explicitly formulated to be food-safe, focusing on cutting boards, salad bowls, butcher blocks, and kitchen countertops.

What sets this product apart, in my experience, is its complete non-toxicity, which makes it ideal for wooden kitchen countertops without any concerns. Its fast drying time is another plus, drying to the touch in under two hours. This allows for multiple recoats daily, making project completion much more efficient.

Even better, the polyurethane surface becomes usable in just 72 hours. However, I’d recommend checking the cure time and allowing it to fully cure before using the countertop for any food-related tasks.

Once the surface has fully cured, it’s perfectly safe for food contact, and you can use it for any kitchen role without any health worries.

I’ve also found it to be beginner-friendly. Its self-levelling property ensures a smooth application process, even for those new to DIY projects. No need to fret about brush marks; they don’t appear on your project, giving you a professional-looking finish with ease.

Is Polyurethane Food Safe for Wood Countertops?

Yes, poly is food-safe and suitable for wooden kitchen countertops. However, the Food and Drug Administration (FDA) notes that the finished surface must be allowed to dry and cure fully before being considered food-safe polyurethane

This cure time varies from one poly to the other, so you need to read the label for the manufacturer’s recommended drying and curing times. This will help ensure you are using the product safely. 

Using a polyurethane surface for food handling before it is fully cured can be risky. The product may release chemical fumes and odors that can cause negative symptoms when used before fully cured.

Types of Polyurethane for Countertops 

The two main types of polyurethane available on countertops are oil-based and water-based poly. Each type has distinctive characteristics that make it a better choice than the other.

Understanding these characteristics can help you choose better for your project.  

i.Oil-based poly 

This type of liquid coating contains solvents that can be highly flammable, so the product requires careful handling away from flame-causing agents.

The solvents also give oil-based poly a higher toxicity profile, so you must wear a protective mask or respirator when handling it.

The product can emit toxic fumes for several weeks after application. Therefore, paying careful attention to the cure time is recommended to decide when to use the polyurethane surface correctly. 

On the brighter side, oil-based poly can be highly durable and resistant to scratches. Even though different sheen levels are available, the product also dries to form a glossy finish. 

You must use solvents like mineral spirits or turpentine to clean oil-based poly. This may be challenging for people who do not keep such solvents at home.

Also, read our article “Is oil-based polyurethane” to gain a deeper understanding of its water-resistant properties and applications.

ii. Water-Based Polyurethane  

This type of poly consists of water instead of toxic solvents are the base. This use of water makes water-based poly safer, with low toxicity levels. 

This polyurethane dries faster, so you can expect shorter curing times than oil-based poly. The poly also cleans up easily with mere soap and water, making it stress-free to use.

Water-based poly has very low volatile organic compound (VOCs) levels in its profile, so you may apply it to your countertop without wearing any special breathing equipment. 

Most water-based polyurethanes will also go on clear and stay clear over time. This is as opposed to oil-based polyurethane, that might turn amber with time. Some oil-based polyurethanes also carry a yellowish tint. 

On the flipside, water-based poly may be less durable and not hold up well to heat. Nonetheless, this type of poly remains the better choice for most indoor applications. 

What to Consider When Selecting Polyurethane for Countertops 

Knowing what to look for in any product can help you choose better. So this section helps you with choosing a polyurethane finish for your wood countertop. 

Sheen level

Polyurethane can be high-gloss, semi-gloss, satin, or matte. High gloss finishes reflect the most light, while matte and satin polyurethane finishes reflect the least light. 

So if you have a small kitchen, you might be better off with a relatively glossy finish that will help make the space look brighter by reflecting more light.

Food safety

Kitchen counters are often used for food preparation. This means the product you use to coat that surface must be safe for food contact. Otherwise, you could be looking at potential food poisoning issues. 

That said, you should also look for a safe countertop for pets and people, such as maple.

Durability 

This is a no-brainer. Not all polyurethane brands will give you the same service life, so you want to go for the one that will last the longest on your countertop. Such a product gives you the biggest bang for your buck and saves you money in the long run. 

Eco-friendliness

Oil or solvent-based polyurethanes consist of chemical solvents that emit potentially toxic fumes throughout their curing periods. Such volatile organic compounds (VOCs) from these products generally harm the environment.

On the other hand, water-based finishes tend to be low-VOC, making them friendlier to the environment. So you may want to go for these safer alternatives whenever that option is viable. 

Drying time

No one wants to take several days on one project when they could complete it sooner. While some polyurethanes dry to the touch in 30 minutes, others can take anywhere from 4 to 6 hours to dry to the touch. 

The product that dries to the touch in half an hour will allow you to recoat in about two hours, meaning you can complete the entire project in just a couple of hours within the day. 

In contrast, the product that takes up to six hours to dry to the touch may need eight hours to be ready for recoating. Therefore, when using such a product, you may be unable to complete the project in less than three days, which can be inconvenient. 

So it makes sense to go for a fast-drying poly whenever possible to finish your projects sooner.

Sealing Butcher Block Countertops with Polyurethane

Step1: Assemble the supplies you’ll need and prepare the workspace. 

Step2: Sand the wood countertop along the wood grain to remove any blemishes such as heat rings and make it smooth. 

Step 3: Wipe the sanding dust with a tack cloth and let the wood dry completely before applying polyurethane. (Find out how to remove bubbles from dried polyurethane)

Step 4: Seal the wood with thinned poly. To make the thinned poly, use a glass jar to mix oil-based poly with mineral spirits in the ratio of 2:1 or water-based poly with water in the same ratio. Stir the mixture gently with a stick, taking care not to disturb or shake it to introduce bubbles. Then apply with a brush. 

Step 5: After the sealer has dried completely, apply polyurethane to the wood with natural bristles (when applying oil-based polyurethane) and synthetic bristles (for water-based poly).

Step 6: Wet sanding the polyurethane and applying additional coats of the product as directed on the label.
