It is important to protect the wood surface from wear and tear when sanding. A sanding sealer should be applied after the sanding process in order to prevent this from happening. Additionally, the sanding sealer works as a pore filler. 

Before you start looking for a sanding sealer, it is important to understand what to look for. As a result, you will be able to select the best product for your needs that produces a great result on your bare wood surface. 

Here are some of the factors that you need to consider when choosing a sanding sealer for your next project:

1. Drying Speed

You must consider the drying time of the sanding sealer in order to determine when you will be able to apply the top coat. If you want to save time, then a sealer that dries quickly is ideal.  

This is because it dries rapidly and can be quickly sanded. With a quick-drying sealer, you will find that your job becomes easier as there is less waiting time.

2. VOC Content

The volatile organic compounds contained in the sanding sealer determine how harmful the product is to you and to the environment. 

In most cases, you will find that the best sanding sealers are formulated with low VOCs. This makes them safe to use around the house and produces better indoor air quality.

3. Compatibility with Top Coats

4. Size

It is essential to consider the size of the sanding sealer you are looking to buy. This is because the size determines the number of projects you can work on with it. 

If you are planning to work on a large project, then you need to buy a product that comes in a larger size so that you can use it for longer.

5. Wood Type Compatibility

The sanding sealer or pore filler that you choose should be compatible with the type of wood that you are working on. 

For instance, if you want to use it on hardwood, then make sure that it is compatible with this type of wood. This is because different types of wood require different finishes and sealers for maximum results.

6. Thickness

In order to determine how often you will need to apply a new layer of sanding sealer, you should consider the thickness of the wood grain filler

Make sure that you select a product with a good thickness to last longer and produce great results for fine protection.

When selecting a product, it is better to choose one that sticks to its color, especially if you are going for a natural or light color for your wood surface.

10. Clean-up

In order to ensure that your surface remains in its original state, the sanding sealer should be easily cleaned. This means that you don’t need to spend long working on the project.
