Understanding the Differences Between Sealcoat and Slurry Coat

Types of Slurry Seal. To make things more complicated, slurry seals can be broken down into three different categories depending on the size of the aggregate they contain. Type I slurry seals contain fine aggregates, with diameters less than 2.36mm. This type of slurry seal is commonly used to treat lower traffic areas such as parking lots.
