There’s a lot of debate out there about how many coats of polyurethane you really need on a guitar. Some say that three coats is the way to go, while others say that one or two is plenty. So, what’s the truth?
The answer, unfortunately, is that it depends. The number of coats you need will depend on the type of polyurethane you’re using, the environment you’re in, and the finish you’re going for.
Let’s start with the type of polyurethane. There are two main types of polyurethane: oil-based and water-based. Oil-based polyurethane is more durable and will last longer, but it’s also more difficult to apply and can yellow over time. Water-based polyurethane is easier to apply and doesn’t yellow, but it’s not as durable.
Next, let’s talk about the environment. If you’re in a humid environment, you’re going to need more coats of polyurethane to protect your guitar. On the other hand, if you’re in a dry environment, you can get away with fewer coats.
Finally, let’s talk about the finish you’re going for. If you want a high-gloss finish, you’re going to need more coats. If you’re okay with a more matte finish, you can get away with fewer coats.
So, how many coats of polyurethane do you really need? It depends on the type of polyurethane, the environment, and the finish you’re going for. If you’re not sure, it’s always best to err on the side of more coats. Better safe than sorry!
How long does polyurethane take to cure on guitar?
This is a question that often plagues guitar players and luthiers alike. The answer, unfortunately, is not a simple one. The curing time of polyurethane can vary greatly depending on a number of factors, such as the type of polyurethane used, the thickness of the finish, the temperature and humidity of the curing environment, and so on.
In general, though, you can expect polyurethane to take anywhere from 24 to 48 hours to fully cure. However, it’s important to note that the curing process is not complete until the finish is hard, dry, and smooth to the touch. So, if you’re planning on playing your guitar or doing any other type of work on it within that time frame, it’s important to be extra careful to avoid damaging the finish.
Once the polyurethane has cured, it will be very durable and will protect your guitar from scratches, dings, and other wear and tear. However, it’s still a good idea to be careful with it, as it can be scratched or chipped if you’re not careful.
If you’re looking for a durable, protective finish for your guitar, polyurethane is a great option. Just be sure to give it plenty of time to cure properly before putting it to use.
