Types of Sealers

There are different types of sealers but the two most common types are Water-based and polyurethane sealers. Water-based sealers are highly preferred by homeowners. These sealers don’t change the appearance but they are highly environment friendly.

They come with very low chemical solvents which makes it safe for use around pets and kids. However, some water-based sealers penetrate into the wood grain and cause the wood to expand a bit.

On the other hand, polyurethane sealers are not environment friendly, they contain high chemical solvents so they are not safe using around kids and pets.

But the best part of these sealers is they are incredibly durable and they can clean easily with soapy water. Polyurethane sealers are made of resins and sealants.


When it comes down to the appearance of the sealer, there are three types, Clear sealers, semi-transparent, and tinted sealers. Clear sealer doesn’t change the appearance, which means it doesn’t add any color from its own.

Clear sealers are used in woods which already looks good. For example, if we talk about cedarwood. Cedarwood grains look very good, when you add a clear sealer, the grains will be shown.

Semi-transparent sealers add little tone and at the same time, the wood grains will also be shown. These sealers enhance the wood grain color a bit. And lastly, tinted sealers add colors, there will be different tones and you can choose one that goes with the wood color.

Sealer Coverage

When you purchasing sealers, you will have to determine how big the wood area is that you will be sealing. And you will have to pick according to that. Normally, sealers are measured square feet per gallon. Measure the wooden area and then purchase the needed amount.

However, not every type of sealer will give you the same coverage. Water-based sealers will give the highest coverage where polyurethane sealers give a little less. Whatever it is, the coverage will be written on the gallon so check wisely.

Apart from that, coverage depends on the porosity of the wood as well. On an extremely smooth wood surface, you will get good coverage.
