Polyurethane is a popular choice for outdoor projects. You'll find out about the different types of polyurethane: oil-based polyurethane (Wipe-on), oil-based polyurethane (Naphtha-based) and others. To avoid streaks and drips, you will also learn how to apply the finish by using a brush. However, you need to keep in mind that the process of applying polyurethane may have several disadvantages, and homeowners should take these into account before deciding which type of finish to use.
Polyurethane oil-based
Clean the surface with mineral oil or alcohol before applying polyurethane. The purpose of wiping the surface is to remove any air bubbles. Water-based polyurethanes generally require three to four coats to attain a satisfactory finish. A thin coat of polyurethane can be applied to minimize bubbles. Apply a thin coat of polyurethane to the surface. Wipe it clean with a dry cloth or mineral spirit.
Polyurethane is easy to wipe off
The wipe-on polyurethane finish is an option to oil-based, branded finishes. This type is water resistant and scratch-resistant. Wiping polyurethane has a lower cost and does not require high end spray booths. You can thin the wipe-on adhesive with mineral spirits before you apply it to your project. Oil-based poly can be mixed 1:1 with mineral spirits, and wipe-on poly can be purchased pre-mixed.
Thinning polyurethane with naphtha
Protective gear is recommended before you begin the process of dipping your brush or rag in a bucket of polyurethane. Exposure to high levels of mineral spirits can cause skin irritation. You should dispose of any thinners that are used to thin polyurethane. Handling thinning agents requires that you wear gloves and long sleeves. The drying process will not be accelerated by adding more substance.
Use a brush to apply it
When applying polyurethane, two basic methods are recommended: brush on and wipe on. While brush on provides the best protection, with minimal buildup or drips, it is easier to wipe on without using brushes. The application is simple and the finish can be dried in as little as four to six hours. Wipe on finishes take more coats but are better for stair balusters or other flat areas.
Drying time
Drying time for finishing polyurethane can be affected by several factors. You want to achieve the best results so apply the coating during warm days. Apply the coating again after sanding off any traces of this. Avoid applying the coating at high temperatures as this could cause cracking. You should use oil-based polyurethane.

- 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)

How To
How to properly use your handsaw
The wood is cut into pieces using a hand saw. The most common types of hand saws are circular saws, jigsaws, table saws, band saws, saber saws, crosscut saws, miter saws, and rip saws. A handsaw is a tool made out of metal or plastic that cuts material such wood, plastics, metals etc.
The main advantage of using a hand saw is its ability to make precise cuts at any angle without adjusting the blade. The blades can also be sharpened easily, which is not possible with power tools. But there are disadvantages. For example, they are heavy and bulky, so you must be careful when transporting them. You could also injure your self if you don't know how to use them.
You can hold a handsaw in many ways. When cutting, you should keep your hands away from the blades. If you don't, you might get hurt. You should hold the saw with your fingers close to the handle. Your thumb should be at the top of your blade. This will ensure that you don't accidentally touch or scratch the blade.
Never place anything under a piece of wood that you're cutting with a handsaw. Doing this would cause the blade to slip off the wood's surface. Before cutting, be sure to check the area. Make sure no nails or screws are hidden beneath the wood.
While working with a saw, you should always use safety goggles. Safety glasses protect your eyes from dust and make it easier to see what the hand saw is doing. Safety glasses protect your head from flying debris.
Before you start working with a saw, it is important to learn how to use it safely. Practice until you feel comfortable cutting. Once you've mastered the basics, you'll find that you can easily cut almost anything!
