Polyurethane is a sealant that many woodworkers use to protect their furniture and other wooden objects they make. It does a great job of sealing the wood and giving it a beautiful finish. But what do you do if you want to remove polyurethane from your project without sanding? In this article, we will discuss how to remove polyurethane from wood without sanding.
To remove the polyurethane from your wood without having to sand it down, all you need is rubber cement thinner and a putty knife. Start by applying the rubber cement thinner to your wood with a rag. Once the surface is covered, spray on a liberal amount of mineral spirits. Let it sit for 15 minutes so that the polyurethane can start to soften and bubble up. Then use the putty knife to scrape off as much of the polyurethane as you can. Wipe away the residue with a dry rag and then finish by wiping down the surface with mineral spirits one more time. Let it dry for 24 hours before using or touching it again.
Why Is Polyurethane Used On Wood?
Polyurethane is a synthetic resin that is derived from petroleum. It is used in many different industries, including the woodworking industry. Polyurethane has many benefits, which is why it is so popular among woodworkers.
Some of the benefits of using polyurethane include:
1. It protects the wood from water damage
Water can cause wood to swell, crack, and warp. By sealing the wood with polyurethane, you can protect it from water damage.
2. It protects the wood from UV damage
UV rays can cause wood to fade and discolor over time. By sealing the wood with polyurethane, you can protect it from UV damage.
3. It is durable
Polyurethane is a very tough and durable sealant. It can withstand a lot of wear and tear.
Water-Based vs. Oil-Based Polyurethane
Polyurethane comes in two different types: water-based and oil-based. Water-based polyurethane is the most popular type because it is easier to apply and it dries faster. Oil-based polyurethane is more durable and gives the wood a deeper, richer color. But it is also more difficult to apply and it takes longer to dry.
When deciding which type of polyurethane to use, it is important to consider the project you are working on. If you are sealing a piece of furniture that will be used a lot, then you may want to use oil-based polyurethane. But if you are sealing a piece of art or something that won’t get a lot of use, then water-based polyurethane would be a better choice.
