How to Sealcoat a Big Job in a Short Time


DSJH Asphalt Sealcoating tackles 300,000 sq. ft. jobs with a small crew


The crew used Billy Goat blowers to remove debris from the parking lot. They blew out cracks with an air compressor and used a Marathon Equipment Inc. oil-jacketed melter and MAIO banders to apply double tar applications to the cracks. "The pavement was only about seven years old so it wasn't in too bad of shape," LaVerdi says. Once the surface was clean the crew edged the parking lot with a layer of sealcoat, LaVerdi says.The remaining 108,000 sq. ft. of parking lot was sealed in mid-June. Since the office complex was not closed down, D&H had to use traffic cones to block and reroute traffic while working. "We took portions of the parking lot and worked on one at a time," LaVerdi says of the remaining area. He and his crew used the same prep and application process as on the first part of the job.D&H used a 700-gal. Seal-Rite sealcoating tank and 80/70 USA Tips spray tips to spray apply two coats of Star sealcoat. Because of hot temperatures, work started at 6:00 am and was finished by 2:00 p.m. each day. LaVerdi applied the one coat the first day and the second coat the next day. He was able to apply 4,000 gal. in just three and a half days, he says.In Spring 2010, the company took its four-person crew to complete a 300,000-sq.-ft. office complex parking lot sealcoat application in Scran ton, PA. But the challenge wasn't tackling such a large job with a small crew. LaVerdi and crew had to complete 192,000 sq. ft. of the job over the Memorial Day weekend. "I've done big jobs before," LaVerdi says, "but not in such a short time frame. And I've never put down that much sealcoat in one weekend."D&H Asphalt Sealcoating has been in business for 14 years, and co-owners Mark LaVerdi and Donna Haggerty have kept the company small. But that hasn't kept them from pursing large jobs.In that first portion of the job, the entire area being sealed was bordered by curbing, which the crew had to be extra careful around. While LaVerdi sprayed the lot another crew member followed along holding a spray shield to prevent any overspray on the curb.The job called for a double sealcoat application. LaVerdi and crew prepped the job the night before sealing. Since it was a holiday weekend, traffic control was not an issue.The Wilkes Barre, PA, company offers sealcoating, crackfilling, line striping, and snow plowing with 60% of the customers being on the residential side and the other 40% commercial, LaVerdi says."For being as large as it was, the job went super smooth," LaVerdi says.The sealer mix also contained a microflex additive to keep the sand suspended and to help the sealer dry quicker, LaVerdi says. The mix contained 3 Vi lbs. of sand per pound of sealer.

"For being as large as it was, the job went super smooth," LaVerdi says.
