Spec Sheet (PDF) – English | Spanish


MasterSeal is a mineral filled asphalt emulsion sealcoat designed to protect and beautify all asphalt pavement including parking lots, driveways, airports, shopping malls, roadways, and more.

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):

MasterSeal: 100 gallons
Water: 15-25 gallons
TopTuff Polymer Additive: 2 gallons
Sand: 300 – 500 lbs.
Mix materials to a uniform consistency.

NOTE: Zetac additive may also be used with MasterSeal.


For optimum performance two coats of mixed material are recommended. Apply by squeegee, brush, or spray. Allow a minimum of 2 to 4 hours drying time before applying second coat. Allow 24 hours before parking cars or allowing traffic to resume.


Temperatures must be above 50°F both during application and for a period of at least 24 hours after application. Do not apply when rain is imminent or forecast.
