Outdoor sealers are not only worthwhile but also necessary. Experts say that an outdoor sealer adds an extra layer of protection. Without this, the unsealed surface would fail prematurely causing losses in repair. The sealer prevents the surface from absorbing moisture after which it would begin to:

  • Crack
  • Flake
  • Spall
  • Discolor

Perks of using an outdoor sealer

Sealers are mostly used outdoors because surfaces here are subjected to harsh elements including wind, scorching sun rays, rain, snow, dirt, and so much more. For continued protection, the sealer needs to be reapplied every few years by a professional.

There are several types of outdoor concrete sealers and most of these are almost invisible. The final layer application of an outdoor sealer prolongs the life of the installation. Other benefits of adding an outdoor sealer include:

  • Preserves the appearance by blocking the penetration of harsh elements
  • Enhances the appearance by adding sheen
  • Protects against abrasion and wear

To enjoy these benefits, one needs to start by choosing the right outdoor sealer for the job. There are hundreds of products on the market but only one sealer would be perfect for the project. What’s worse is that the wrong sealer can potentially ruin an otherwise flawless installation.

Tips for buying outdoor sealers

These tips are designed to help buyers sort through the numerous options and avoid making any mistakes:

  1. How much outdoor sealer is needed?

Before deciding how much sealer to buy, one needs to calculate the square footage if the surface to be sealed. Keep in mind that larger containers are more economical and it’s also okay to have some extra in case some problems arise later.

  1. Is the sealer compatible with the surface it’s being applied to?

Always check the surfaces that the sealer manufacturer recommends. Do this to verify the compatibility of the product with the surface before applying it. Some sealers may react with certain agents and result in the formation of unpleasant blistering, bubbling, or bleeding of color.

  1. What type of finish is desired?

Outdoor sealers are available in a wide range of sheen levels. Sealers with a medium to high gloss sheen give off a wet look. For applications where sealers with a shiny or wet look are no desirable, people can buy film-forming sealers with matte or low-gloss finishes.

Solvent-based sealers generally enhance the color better as compared to water-based products.

  1. What conditions will the sealer be exposed to?

Find an outdoor sealer that protects surfaces from traffic conditions or the elements that these surfaces are exposed to. The primary sealer that should be used for outdoor surfaces should look natural and provide excellent protection against outdoor exposure conditions. It should also have good resistance to scuffs and staining.

  1. What is the life expectancy of the sealer?

The life expectancy of outdoor sealers depends on the exposure conditions and how well the surface is taken care of. Some of the best sealers, if well maintained, can last for years before requiring reapplication.


Sealers are absolutely important in the overall appearance and longevity of the installation on which they’re applied. Ensure that all installations are sealed to keep looking spectacular for years. These are used to protect outdoor surfaces from damage caused by changes in weather conditions, human activities, and other elements found in nature.
