Best Polyurethane Sealer for Wood

Best Polyurethane Sealer for Wood

A wood sealer can be any finish that creates a layer on top of the wood which seals it from dirt, debris, moisture, and other intrusions. Polyurethane is a popular ingredient in wood sealers because it’s highly durable and resistant, creating a powerful seal that lasts for a long time. If you are looking for the best type of polyurethane sealer, it helps to understand how it works and when it should be used.

When to Use Sealants?
A polyurethane coating is best used on raw or untreated wood or when certain types of finishers are used on the wood itself. If the wood has been treated with an oil-based finish or shellac, then it has already been sealed. This is because oil-based finishes are made from polyurethane so no additional treatment should be necessary. Such finishing products are often called “self-sealing” because they contain polyurethane or oil-based products.

Also, if you have a very dense wood, such as boxwood for example, then you may not require a sealant because the wood itself is so dense that it prevents intrusion from dirt, debris, and other particles. For softer woods, you will want to use a polyurethane sealer first, before using a water-based coating or lacquer. This is because the sealant will lock in the waxes and oils and reduce the number of coats needed of the lacquer or coating.

How to Find the Best Sealer
You’ll want to find a polyurethane sealer that is made for the type of wood that you are working with and offers the right ingredients to properly seal it for your needs. This means doing a little research to find the one that works best for you.

Outdoor or Indoor: Many sealers are designed for wood that will be exposed to the elements such as decks, outdoor furniture, and the like. However, if the object is going to remain indoors and protected from UV rays, then you can choose from different types of sealants.

Compatibility: Be sure that the sealer you use is compatible with any lacquer or finisher that will be applied on top. For example, sanding sealer is not necessary for some types of wood material and is incompatible with certain types of topcoats. So, be careful about the type that you select.

It’s Not Pore Filler:
There is a difference between sealant and pore filler, even though sanding sealer seems similar in composition. So, if you are looking for a pore filler instead, be sure to use that type instead of a traditional sealant product.

Another area where you should do a little research is the materials that go into the sealant itself. When applied, any toxic chemicals are released into the air which may cause harm to those living inside your home. Because of concerns over the toxic properties that many polyurethane wood sealants have as part of their ingredients, the EPA (Environmental Protection Agency) recommends non-toxic varieties like Hybrid Coating Technologies. They offer the same protection without polluting the indoor air environment. If you are looking for a non-toxic sealant for wood, then it would be wise to consult with the experts at Hybrid Coating Technologies for more information.
