- Polyurethane seal: You can choose for either water-based or oil-based polyurethane, depending on your preference.
- Sandpaper: Select sandpaper in various grits, such as 120, 220, and 320, for sanding the wood surface.
- Tack cloth: Sticky cloth to remove dust and dirt from the table after sanding.
- Painter’s tape: Use painter’s tape to protect any areas adjacent to the countertop that you don’t want to get sealant on.
- Plastic or drop cloth: Cover the wood surface with plastic or rags to avoid spillage or dripping of the finisher.
- Sanding block or orbital sander: Use a sanding block or orbital sander to apply evenly wooden table and smooth the surface.
- Brushes or foam brushes: Select brushes or foam brushes appropriate for the type of polyurethane seal you are using. Foam brushes are particularly useful for water-based polyurethane.
- Paint tray or container: Pour the polyurethane seal into a paint tray or container for easier application.
- Stir stick: Use a stir stick to gently stir the polyurethane seal before application, ensuring it is well-mixed.
- Paint roller: This tools is optional used to evenly spread the polyurethane coating on a larger table surface.
- Protective gear: Wear gloves, safety glasses, and a mask to protect yourself from the sealant fumes and for general safety.

Water Based VS Oil Based Polyurethane
Water-based polyurethane and oil-based polyurethane are two commonly used types of finishes for wood surfaces. Here are the key differences between water-based and oil-based polyurethane:
Water-based polyurethane contains water as its primary solvent. Oil-based polyurethane uses mineral spirits or other petroleum-based solvents as its primary carrier. It contains a higher concentration of polyurethane resin, resulting in a thicker and more durable finish.
Water-based polyurethane dries clear and typically has a lighter appearance. Oil-based polyurethanes tend to have a yellowish color that can enhance the richness and warmth of the wood. It provides a more traditional and glossy finish.
- Drying Time
Water-based polyurethane has a faster drying time compared to oil-based polyurethane. It typically dries within a few hours. Oil-based polyurethane takes longer to dry, usually requiring 24 to 48 hours between coats.
- Odor and VOCs
Water-based polyurethane has a milder odor and emits fewer VOCs compared to oil-based polyurethane.
Water-based polyurethane provides good durability, but considered slightly less durable than oil-based polyurethane. Polyurethane does offer good resistance to moisture, stains and scratches, but requires more care and touch-ups in high-touch areas.
Ultimately, the choice between water-based and oil-based polyurethane depends on personal preference, specific project requirements, and environmental considerations.
Finish Wood Countertop With Epoxy
Using epoxy is a good choice because of its outstanding performance and stunning aesthetic appeal. First and foremost, epoxy provides an incredibly durable and long-lasting finish. Epoxy also creates a stunning, high-gloss finish that enhances the natural beauty of the wood. It brings out the grain and depth of the wood, resulting in a visually appealing surface. Another advantage of epoxy is its ability to fill in imperfections and create a smooth, seamless surface.
Epoxy is also relatively easy to clean and maintain. It can be wiped clean with mild soap water and resists staining from common household substances. However, it is important to note that working with epoxy requires careful preparation and attention to detail. Proper surface preparation, mixing ratios, and application techniques are crucial to achieving the desired results.

Why Oil Didnt Work For Wood Countertop
There could be several reasons why oil didn’t work as protective coating for a wood countertop. One of the reasons for this is that they are less compatible with oil coatings. Certain woods, such as teak or cedar, contain natural oils or resins that can hinder the absorption and adhesion of oil.
Another factor to consider is the surface preparation. If the wood surface wasn’t properly sanded, cleaned, or free from contaminants, the oil may have difficulty penetrating and adhering to the wood fibers. Environmental factors can also affect the performance of oil finishes.
High humidity or insufficient ventilation during application and drying can prolong the curing time and result in a tacky or less durable finish. It’s important to ensure appropriate conditions for proper drying and curing.
Furthermore, the expectations and desired outcome should be considered. If a high-gloss or highly resistant finish was desired, oil finishes may not have met those expectations. Oil finishes typically provide a more natural and matte appearance while offering moderate protection. If a more durable and moisture-resistant finish is desired, alternative options like polyurethane, epoxy, or varnish might be more suitable.
Lastly, proper maintenance and care play a role in the longevity of an oil finish. Wood countertops treated with oil may require periodic reapplication and routine maintenance. If the countertop wasn’t adequately protected from moisture, heat, or heavy use, the oil finish might have worn off or become less effective over time.
When it comes to finishing a wood countertop, you have several options to choose from: polyurethane seal, oil, or epoxy. If you prioritize a food-safe finish, using oil and wax can be an excellent choice. Mineral oil is a popular option as it is non-toxic and safe for contact with food. Oil finishes like tung oil enhance the natural beauty of the wood while providing some water resistance, but they may require more frequent reapplication.
Another suitable choice is butcher block oil and butcher block countertops, specifically formulated for wooden surfaces that come into direct contact with food. Applying multiple coats of either oil and wax finish will not only enhance the natural beauty of the wood but also provide a protective layer that repels moisture and stains, ensuring your butcher block countertops remains durable and maintains its aesthetic appeal for years to come.
So, it’s a good idea to choose some of the right woods so that you can do a more precise, easy, and safe finishing. There are many types of wood that are commonly used for kitchen countertops.
