Sealcoat & Crack Filler/Sealant Calculators
Applying sealcoat is essential to good pavement maintenance. Sealcoat is the primary protective layer for pavement. Sealcoat will protect your pavement from water, UV rays, and chemicals. Sealcoat will also seal hairline cracks. If you are spraying sealcoat it can be diluted up to 25% with water to give you more coverage. Filler in the form of sand can also be added to sealcoat. Before you apply sealcoat you want to make sure you have filled any cracks that are 1/4'' or larger with hot rubberized crack fill.
It's easy to calculate how much sealcoat you need: simply measure the length L in feet and width W in feet of the area you want to seal. Multiply them together to get a total measurement in square feet. Fill in the blank with the total number of square feet and the calculator will return the number of gallons you need.
You will need 10 gallons of sealcoat to cover 800 square feet.

Crack Fill/Seal Calculator
Hot crack filler is the best way to seal cracks. The heat creates better bonding between the crack filler and the pavement. In most cases you want to first fill cracks that are deeper than 1/2'' with sand. Crack filling should only be about 1/2'' deep for the best performance. The main reason you want to fill cracks is to stop water from getting into your pavement. Once water gets into your pavement the damage to your pavement will only accelerate. If water gets to the sub-base layer you will have erosion and your pavement will fall apart requiring you to do a complete re-pave.
It's easy to calculate how many pounds of crack filler you need: simply measure the total linear length of cracks you have in feet. Fill in the blank with the total linear feet of cracks and the calculator will return the number of pounds you need.
You will need 30 pounds of crack fill to cover 200 linear feet.
