Asphalt Sealcoating and Crack Filling Calculators

We have compiled several sealcoating and crackfilling related calculators here to help you with your estimations.

This information may not apply to all Sealcoaters, depending on their level of expertise and experience. We are providing this information primarily to the novice.

A basic rule to follow when determining how much sealcoat you need is to figure 1 gallon per 100' square feet of pavement, if the pavement has been sealed before. It may take 1.5 gallons if it has never been sealed. This is assuming your sealcoat is diluted at 30%

Mixing Sand

Recommended Sand Amounts:

For normal application - 2 to 2.5 lbs. per gallon of undiluted sealer.
For rougher pavements, sand loading of 4 to 4.5 lbs. per gallon of undiluted sealer may be nessasary accomplish proper texturing and filling of fine cracks.
Sand should Be clean, water-washed, pure silica type, with irregular particle shape, free of contaminants, metals, clay, trash and organic matter.
Fineness 50-75 MESH AFS (American Foundrymen Specification)
Angular.
