You might wonder why polyurethane has become so popular for outdoor projects. In this article, you'll learn about different types, including Wipe-on polyurethane, Oil-based polyurethane, and naphtha-based polyurethane. You'll also learn how to apply the finish using a brush to prevent streaks and drips. You should be aware that polyurethane can have some disadvantages. This is something homeowners need to consider before choosing the finish.
Polyurethane based on oil
Use mineral oil or alcohol to thoroughly clean the surface before applying a polyurethane coat. Wiping down the surface is necessary to eliminate air bubbles. To achieve a satisfactory result, most water-based polyurethanes will require three to four coats. Apply a thin layer of polyurethane to reduce bubble risk. Be sure to clean the area with mineral spirits or a lint-free cloth before applying a finish.
Wipe-on polyurethane
Wipe-on finishing polyurethane is an alternative to oil-based, branded finishes. This type is water resistant and scratch-resistant. Wiping polyurethane without the need for high-end spray booths is an economical option. It can also be applied without the use a brush. Use mineral spirits to thin wipe-on polyester before you apply it to your project. Oil-based poly can easily be mixed 1:1 with mineral spirit, and wipe-on plastic can be purchased pre-mixed.
Thinning polyurethane with naphtha
Wear protective gear before you start the process of dipping a brush in a bucket filled with polyurethane. High levels of mineral spirits can cause severe skin irritation. The thinners used for thinning polyurethane should be disposed of properly. When handling thinners, gloves and long sleeves are essential. Adding more of the substance will not accelerate the drying process.
Applying it with a brush
The two most common methods for applying polyurethane to your skin are brushing and wiping. Brush on offers the best protection with minimal buildup and drips, but wipe on can be difficult to apply without brush strokes. Brush on finishes dry in approximately four to six hours. Wipe on finishes require more coats, but are a better choice for stair balusters and other small, flat areas.
Drying time
There are many factors that affect the drying times of finishing polyurethane. For best results, apply the coating during warmer days, avoiding the worst-case scenario where the outer surface dries too fast. Sand the coat and apply again if you experience this. Additionally, avoid applying the coating in very hot temperatures, since this can cause the finish to crack. Use oil-based polyurethane at a temperature of 70°F or 21°C.

- Most woodworkers agree that lumber moisture needs to be under 10% for building furniture. (woodandshop.com)
- If your lumber isn't as dry as you would like when you purchase it (over 22% in Glen Huey's opinion…probably over 10-15% in my opinion), then it's a good idea to let it acclimate to your workshop for a couple of weeks. (woodandshop.com)
- Overall employment of woodworkers is projected to grow 8 percent from 2020 to 2030, about as fast as the average for all occupations. (bls.gov)

How To
How to make wooden joints
This tutorial will demonstrate how to join two pieces together of wood. We'll use the "pocket hole joint," which means we drill holes in the wood and then glue them together. This works well if the wood is straight and smooth. You may want to consider other methods, such as dowel joining. These are the steps
-
Drill Pocket Hole Joints. To start, measure and mark where you want to put the pocket hole joint. Then drill 3/4 inch deep holes into the ends of each piece of wood using a jig saw or handheld drilling machine.
-
Sand Smooth. Sanding the edges of the wood will help to prevent the joint from splitting later.
-
Glue Together Apply glue to the sides of both wood. Allow the wood to rest for five minutes before clamping it together.
-
Clamp the Pieces Together. After the glue has dried you can attach the pieces to form a flush joint.
-
Trim Joinery. Trim any excess wood surrounding the joint once the glue has dried completely.
To be able to turn the pieces inside-out, leave enough room between them.
