You may wonder why polyurethane is so popular for outdoor projects, and that's an excellent question. You'll find out about the different types of polyurethane: oil-based polyurethane (Wipe-on), oil-based polyurethane (Naphtha-based) and others. Furthermore, you'll learn how a brush can be used to apply the finish to prevent drips and streaks. 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.
Oil-based polyurethane
Before applying a polyurethane finish, clean the surface thoroughly with mineral oil or alcohol. Wiping down the surface is necessary to eliminate air bubbles. Generally, water-based polyurethanes require three to four coats of polyurethane to achieve a satisfactory finish. Apply a thin layer of polyurethane to reduce bubble risk. Apply a thin coat of polyurethane to the surface. Wipe it clean with a dry cloth or mineral spirit.
Wipe-on polyurethane
An alternative to oil-based finishes, wipe-on finishing polyurethane offers a clean option. This type of finish offers a water barrier and good scuff resistance. Wiping polyurethane has a lower cost and does not require high end spray booths. To apply wipe-on poly, thin it with mineral spirits before applying it to the project. Oil-based plastic can be mixed 1:1 using mineral spirits. You can also buy pre-mixed wipe on poly.
Thinning polyurethane and naphtha
Protective gear is recommended before you begin the process of dipping your brush or rag in a bucket of polyurethane. High levels of mineral spirits can cause severe skin irritation. Proper disposal is required for thinners 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.
Apply it with a brush
When applying polyurethane, two basic methods are recommended: brush on and wipe on. 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 are easy to apply and dry in between four and six hours. Wipe-on finishes require more coats but they are a better choice if you have stair balusters or small, flat areas.
Drying Time
The drying time for finishing polyurethane depends on several factors. 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. The coating can crack if it is applied in extremely hot temperatures. Oil-based polyurethanes should be used at temperatures no higher than 70°F/21°C.

- 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 join hardwood without using nails
Woodworking is a hobby that many people enjoy doing. It is relaxing and enjoyable because you can create something useful with wood. You might want to join two pieces from the same wood, but you don't need to use nails. This article will explain how to do this so that your woodwork projects stay beautiful.
You will first need to trim the edges of your wood pieces before joining them. Do not leave any sharp corners as they could cause problems down in the future. Once you have done that, you can begin gluing your boards together.
If you are working on hardwood, you should only use glue on one side. If you are using softwoods such pine or cedar, glue should only be applied to one side. After applying the glue, press the boards firmly until they are completely stuck together. Before moving onto the next step, make sure the glue has dried completely.
Once you've glued your boards together you will need to drill holes in the joints to accommodate screws. Depending on what type screw you choose, the size of these holes will depend on how big they are. For example, if you intend to use 1/2-inch wood screws, you need to drill a hole that is at most 3/4 inches deep.
After drilling your holes, drive the screws into the board's backside. Do not hit the boards' front surfaces. It will ruin the finish. Be careful not to drive the screws too hard at the ends. This will prevent the wood from splitting.
After your project is completed, you will need to protect it from the weather. You have two options: seal the whole furniture piece or just the top. You will want to choose a product that will be durable for many years. Some examples include oil-based varnishes, polyurethane, shellac, lacquer, etc.
These products can be found in most home improvement shops. Just make sure that you buy the right kind for the job. Don't forget to keep in mind that some finishes are toxic. So, always wear protective gear when handling them.
