how many square feet of coverage per gallon

Thank you for posting your inquiry. A one-quart container of DAP WELDWOOD Original Contact Cement will cover approximately 57 sq. ft./quart (one side application @ 3 dry grams per sq. ft). This is equivalent to 27 sq. ft. of bonded material (depending on the porosity of the application surfaces). Should you have any additional questions or require further assistance, please feel free to contact DAP’s Technical Customer Service Department at 888-327-8477.
