As a woodworker, you will need a clear coat product for different applications. For example, you may want a formula for indoor purposes, which dictates that you get a product that dries quickly and has a low odor.
For outdoor purposes, a formula that will do a good job is flexible, not harmed by temperature changes, and has UV blockers.
Some products are useful for specific projects such as tabletops and cabinets and others on floors and hardwoods. Therefore, you need to use them on the recommended surfaces for ideal results.
- Safe to use.
Your health comes first, even when it comes to the woodworking projects you are using. Therefore, you should get a product that does not get you nauseous or make your eyes itch.
A toxic product and has a strong odor is not safe for you, especially if you are using it for interior projects.

Using an easy to understand formula makes work enjoyable. The product needs to have clear instructions on how and where you will get desirable results.
When shopping for the product, you also should factor in the duration you have to get the job done. If there is limited time, get a self-leveling formula that does not require sanding. Some formulas need you to fill the surface before applying them, and although the requirement is useful, it can slow down your working speed.
You will spend differently based on the product you need, and when you check the requirements of your project, you will have an idea of how much you need. For example, the more features and purposes the product has, the more expensive it will be.
Maintenance costs should also be included in your budget statement as some products will not clean up with just water but require cleansers such as mineral spirits, among others.
Since proper maintenance contributes to the formula’s durability, get one that you can comfortably sustain.
