Do I need a professional to do Asphalt Topping?
I just got a 4,500 square feet driveway and parking lot resurfaced with new asphalt. The contractor now is advising me to get the asphalt seal coated with some type of topping.

Here's my question......Do I really need to seal coat it? Next question is do I need to hire a professional to do it, or can I do it myself?

Q. Should a newly paved driveway or parking lot be sealed (or seal-coated)?
A. No. A well-designed and constructed low traffic volume pavement, such as a driveway or parking lot, should not require sealing for approximately 2 to 5 years – depending on severity of climate and quality of original work. If a new pavement is porous, meaning it allows water into the pavement rather than shedding, or draining off, the rain, this pavement might benefit from a light application of a low viscosity asphalt emulsion. See Application Instructions below.
Q. When should a driveway or parking lot be sealed?
A. Sealing is effective to renew old asphalt surfaces that have become dry and brittle with age, to seal small surface cracks and surface voids, and to inhibit raveling (loss of surface aggregate). So, sealing should be done as soon as any of these distresses are noted.

I guess a parking lot is sort of like a floor?

I'm surprised it's been on here all day and no one has moved it.
