Surface Preparation

New asphalt surfaces must cure a minimum of four weeks under ideal weather conditions before sealcoating is applied. Surface must be clean and free from all loose material, dirt, and dust. Cracks should be filled with SealMaster Hot Pour or Cold Applied crack fillers. Treat all grease, oil, and gasoline stains with SealMaster® Petro Seal or Prep Seal.

Mixing Procedures

For optimum results, mix MasterSeal™ in accordance with the following mix design (based on 100 gallons for ease of calculation):

Mix materials to a uniform consistency.

NOTE: Zetac additive may also be used with MasterSeal™.
