Understanding Polyurethane And Its Common Uneven Finishing Issues
If you have recently had your hardwood floors covered with polyurethane, you would expect them to look smooth and even. Unfortunately, that is not always the case. Uneven polyurethane finishing can leave your floors looking shoddy and uninviting. In this blog post, we’ll explore the causes of uneven polyurethane finishes and how to fix them.
Introduction To Polyurethane
Polyurethane is a popular wood finishing material because of its high durability, clarity, and water resistance. It is a type of varnish that comes in either oil or water-based form. Oil-based polyurethane takes longer to dry but offers more durability than water-based polyurethane.
The water-based product, on the other hand, dries faster and provides less yellowing over time.
Common Applications For Polyurethane
Polyurethane can be applied to several surfaces, including furniture, cabinets, and floors. For floors, it serves as a topcoat to protect the floor from scratches, stains, and wear.
Causes Of Uneven Application Of Polyurethane
Uneven polyurethane finishing can be attributed to a number of factors. These include:
- Incorrect sanding: If the floor was not sanded down uniformly or properly before applying polyurethane, it may result in uneven finishes.
- Poor application technique: If the polyurethane is applied too thickly, it may not dry evenly. The use of the wrong brushes or rollers can also cause uneven finishes.
- Poor quality polyurethane: Inferior brands of polyurethane may not ensure a uniform finish.
- Humidity: High humidity levels can also cause uneven drying of the polyurethane.
Now that you know what causes uneven application of polyurethane, let’s take a look at how you can fix it.
Fixing Uneven Polyurethane Finishing
The following are simple steps you can take to fix uneven polyurethane finishing on your floor:
- Inspect the floor: Check for bubbles, peeling, or cracks in the finish. Ensure the area you want to fix is clean and dirt-free.
- Sanding the surface: Use sandpaper to even out the uneven areas. Ensure you sand the floor evenly, not too much and not too little. Use progressively finer grain sandpapers to finish off sanding.
- Clean the surface: Use a vacuum cleaner to remove all dust, debris, and sanding residues. Then use a damp cloth to clean the floor.
- Reapply polyurethane: Apply a fresh layer of polyurethane using a lint-free brush or roller. Apply evenly, following the manufacturer’s instructions.
- Let it dry: Leave the polyurethane to dry for the manufacturer’s recommended time.
That’s it! The finishes on the floor should no longer be uneven, and the floor should now look as good as new.
Polyurethane is a great topcoat for floors, but it can be disastrous if applied unevenly. Always ensure to follow the manufacturer’s instructions, use quality polyurethane, and apply it evenly. With these tips, you can now restore your floor’s natural beauty.
