Factors to Consider When Choosing the Best Sealer for Redwood

  • Application methods

It is vital to consider the method you will use for application before purchasing these products. Some available methods include the use of a sprayer, brush, or roller. Using a sprayer tends to be easier among these methods because you can easily spray even the hard to reach areas like corners.

  • Durability

An excellent exterior wood stain offers long-lasting protection, waterproofing, and mildew resistance. It should withstand all the other natural conditions like intense sunlight with damaging UV rays, among others. Therefore, you should consider checking on the warranty status since they differ from one product to another.

  • Formulation

The composition of these products is paramount. Its the one that determines the durability and resistance to mother nature. For instance, a sealer with 100% acrylic formula protects the wood from rain, snow, and sun damage. There are other compositions like oil or water based stains.

  • Application procedure

This is yet another crucial factor to contemplate. Not all of these sealers have the same application procedures. You will find some that will require you first to clean up the application surface, especially pre-painted or stained surfaces. On the other hand, other sealers are ideal for application, even on the painted surfaces.

  • Area coverage

Choose a sealer depending on your project’s demand. The reason is that not all these products have the same area coverage. It’s vital to remember that the application method you employ and the number of coats also determine your sealer’s area coverage.

  • Drying period

How first do you want your project done? With this in mind, go for a redwood fence with a first or slow drying time, depending on your project’s demand.

  • Color

Because these products are available in different colors, go for the one that will match your environment to bring out that beauty in your home.

  • Style

The style also matters a lot. There are two main styles, including transparent and semi transparent. I will recommend that you go for the semitransparent style. The reason is that apart from protecting your wood surface from inhibiting factors, it will also highlight the wood grain to maintain that natural beauty of your wood.

  • Budget

How much do you plan to spend on your redwood fence? This question should always run in your mind while making a purchasing decision. Not all manufacturers charge the same retail price. The price ranges due to the strength, drying period, and durability of the particular stain or sealer. Therefore, go for the one that best fits your budget. However, it would help if you remembered that the cheaper ones would have less reliability than expensive ones.

  • The safety precautions

Since these products are chemical formulations, always remember to wear safety gloves when applying. In case of contact with your hands or eyes, simply wash with soap and water. However, if irritation persists, visit your nearest doctor.


We have just seen how beneficial the best sealer for redwood fence is to most exterior woodworking applications, particularly fencing. Apart from just offering protection against the inhibiting factors, we have seen that the sealers also maintain the wood’s natural beauty by highlighting the wood’s grains.

So which product did I settle for among this top tier list? Well, it had to be the Ready Seal 520 Exterior Stain and Sealer for Wood.

With the provided guide and reviews in this article, I hope it will be easier for you the next time you go shopping. I wish you a happy shopping time.
