Clear Coats for Wood Buyer's Guide
Type of Clear Coat
The finest clear coats are available in both oil and water-based options. Oil-based clear coats form a hard protective shell containing mineral solvents, but they dry slowly and may turn yellow. On the other hand, water-based solutions do not develop a yellowish tint over time, have no strong odor, and dry more quickly compared to oil-based products.
Formula/Composition
When buying a clear coat, I suggest you go for those with quick-drying abilities and UV inhibitors. This formula not only dries fast but also protects the wood from harsh UV rays [1]. They are great in protecting the natural wood around your home.
Use
In my experience, while some clear coats come “ready to use,” others necessitate a bit of mixing before application. Personally, and from discussions with my team, I’d recommend going for the ready-to-use formulas. It saves you from navigating the technicalities involved in prepping the solution.
