Types of Deck Sealers

Deck sealers essentially come in four types depending on their transparency: transparent, semi-transparent, semi-solid, and solid.

Exterior Wood Stains

Deck sealers come in many types. One of the most popular is exterior wood stains. These stains not only keep your deck looking good, but they also protect it from harm. They come in four kinds:

  1. Transparent: This stain lets your wood’s natural look shine through. It fights off water and damage from the sun.
  2. Semi-Transparent: This stain gives a bit of color to your deck but still shows some wood grain. It offers great weather protection.
  3. Semi-Solid: Thicker than semi-transparent, this stain hides more wood but still lets some show through. It protects well against rain and sun.
  4. Solid: The thickest option, solid stain covers all your wood’s color and grain. It offers the highest level of defense against the weather.
