Is Polyurethane Food Safe for Wood Countertops?Yes, poly is food safe and suitable for use on 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. 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 it is fully cured. Types of Polyurethane for CountertopsThe two main types of polyurethane available for use on countertops are oil-based and water-based poly. Each type has distinctive characteristics that make it a better choice over the other. Understanding these characteristics can help you choose better for your project. Oil-based polyThis 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 need to wear a protective mask or respirator when handling it. The product can emit toxic fumes for several weeks after application. Therefore, it is recommended to pay careful attention to the cure time to decide when to start using the polyurethane surface correctly. On the brighter side, oil-based poly can be highly durable and resistant to scratches. The product also dries to form a glossy finish, even though different sheen levels are available. You will need to use solvents like mineral spirits or turpentine to clean oil-based poly. This may be a challenge for people who do not keep such solvents at home. Water-Based PolyurethaneThis 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 kind of 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 compounds (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.

Best Polyurethane for Wood Countertops Comparison Table
What to Consider When Selecting Polyurethane for CountertopsKnowing 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 levelPolyurethane 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 safetyKitchen 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 specific countertop wood that is safe 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-friendlinessOil 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 timeNo 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 PolyurethaneStep1: Assemble the supplies you’ll need and prepare the workspace. Step2: Sand the wood countertop along the wood grain to remove any blemishes and make it smooth. Step 3: Wipe the sanding dust with a tack cloth and let the wood dry completely before applying 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 sand the surface and apply additional coats of the product as directed on the label.
