Waterproofing wooden coasters is as simple as applying a coating. Coatings and varnishes come in a wide variety of styles and functions. There are both water- and oil-based options. These are a stylish way to safeguard your wooden coasters from damage.
Protective Oils
You'll need to apply a finish to your wooden coasters if you care about keeping them in pristine condition or if you just want them to appear nice. Several variations on a finish exist. Varnish, oil, and polyurethane are the three most common coatings. These categories are distinguished from one another in various ways. Depending on your needs, one or the other may be more useful.
Among finishes, varnish has the highest resistance to moisture. This sort of finish may be used on wood, and it's simple to apply. You should use at least three coats to get the finest results. Oiled wood will not hold up well to a varnish finish. In order to get ready for the next coat, it has to be sanded.
Oil treatments can be applied to either unstained or stained wood. Before applying a second application of oil, give it at least a day to dry.
Polyurethane is the most popular coating used today. Your hardwood coasters will have the appearance of plastic after being finished in this manner. It can withstand the elements, is simple to maintain, and secures the area. Compared to varnish, its durability is lacking, but its application is simplified. Both a brush and a foam roller will work for this.
Coasters made from wood can also be coated in polycrylic. Since it is water-based, it dries more quickly than polyurethane and may be used in more situations. You may use it on both light and dark wood. While it does add a layer of protection, it is not as effective as polyurethane.
Nail Polish for Sparse Areas
You'll need a protective coating if you're going to make your own wooden coasters or fix up coasters that have been damaged by water. In order to get the best results from your finish, whether it be lacquer, varnish, or polyurethane, you need apply it correctly. The coasters' longevity is thus ensured.
One of the most common coatings for hardwood coasters is varnish. Putting it on is a breeze, and after it dries, it will last a long time and keep the rain out. On the other hand, before adding a second coat, the finish must be sanded. How often you plan on using the coasters will determine how many coats you need to apply.
Spar varnish, which is water-resistant, is commonly used to cover wooden coasters. You can count on its sturdiness and waterproofness, and it also happens to be aesthetically pleasing. Although not as tough as a polyurethane coating, it holds up well under normal use.
Varnish may be found in a wide range of glosses and plain colors. The best effects will come from using it in thin layers. Additionally, you must wait for it to dry in between coats. All those little fractures in the finish might add up quickly if you're not cautious.
Utilizing a low-priced brush is recommended for applying spar varnish. Coating should be applied in the direction of the grain for a flawless, splinter-free result. If you want to apply a second coat, you need wait at least 24 hours for the first one to dry.
Coconut Oil
If you want to make a wooden coaster that won't get water damaged or just want to make the wood more attractive, tung oil is a simple solution. This oil has a beautiful golden honey color and protects the wood grain naturally. It's also a good option for the planet.
Tung oil is excellent for making watertight wood coasters, however it is not recommended for use on sturdy furniture. However, tung oil is not as long-lasting as the contemporary finishes utilized in the woodworking business today.
Consider a polyurethane coating for your wooden coasters if they'll be used with hot drinks. Finishes like this are frequently used on wood products that need to withstand moisture. You can put it on quickly, and it will keep the rain and dampness out very well.
Wooden placemats can also be sealed with tung oil. Its inherent anti-microbial properties make it an excellent mildew repellent for wooden surfaces. Tung oil is excellent for making wooden coasters watertight, but it does not last as long as other contemporary treatments.
When used occasionally, oil coats are fantastic. They are a terrific value when considering their low cost, simple installation, and high aesthetic value. However, they offer almost no protection against water.
Paste waxes can also be used. The coating isn't as watertight as polyurethane, but that's the only real drawback.
