One Seal To Rule Them All: 6 Types Of Seal Coats & When To Apply Them

Sealcoating is a vital process that protects asphalt surfaces from potential damages from water, oil, UV rays. There are many types of sealcoating available on the market today, so it is essential to do your research before deciding which one will work best for your surface and specific requirements.

This blog post will discuss various types of sealcoats and where they should be applied.

Chip Seal

This type of sealcoat is often used to improve low friction and skid resistance on high traffic surfaces such as airports, commercial parking lots, roads with long-term wear patterns, or where a temporary surface is needed (e.g., construction sites). It is important to note that this type of sealcoating must be reapplied regularly due to its temporary nature.

Refined Tar-based Sealcoating

A refined tar-based sealcoat is a good choice for surfaces such as parking lots, roads with heavy traffic, and those requiring exceptional durability. This sealcoating comes in two types: open-graded and closed-graded.

The difference depends on how much stone has been mixed into the oil to create it; less stone means a darker, more uniform color. Open-graded types are lighter in color and have a lower stone content, while closed-graded types are dark with high aggregate levels (e.g., sand or crushed limestone).

Asphalt Emulsion Sealcoating

Asphalt emulsion sealcoating is a popular choice that has been used for decades. In fact, the asphalt itself was once only available in an emulsified form until the 1950s, when it became possible to refine this substance into what we know today as blacktop or pavement. Like refined tar-based types of sealcoating, emulsified types also contain petroleum products and aggregate (the latter is mixed into the emulsion).

Oil-Based Sealcoating

Oil-based sealers tend to dry slower than other types, which can lead to cracks. While oil sealers are still effective, they have become less popular due to new types that work better. Oil-based sealers are suitable for driveways and roads with light traffic where durability is not as important.

Fast-Dry Sealcoating

This is a relatively new option that is becoming increasingly popular. It is advertised as offering the best of both worlds, drying quickly and offering durability. While it might be more practical for commercial purposes like drive-through restaurants, fast dry sealcoating is not recommended for home use due to its high price tag.

Water-Based Sealcoating

Water-based sealcoating is the most common type of sealcoat. This type of coating has a slightly acidic pH which will help it adhere to road surfaces better than oil-based types. Still, its primary advantage is that it is non-toxic and environmentally safe compared with other coatings. Water-based types are used on parking lots, driveways, and streets.
