I have a 24 year old asphalt driveway. It has never been sealed or coated with anything. Just last year it started to show a few cracks. Is there a correct way to seal and fix these cracks? Water based, oil based, roll it, brush it, etc. I can roll it myself. [/quote
How long is the driveway and how many sq feet do you need to cover? What is your budget?
Up here in Canada the guys that seal it don't have the stuff that lasts a long time. Maybe 2 years then it starts to fade. I usually use the pails of sealer and apply it with a squeegee and brush. That will last about 2 years before it washes/fades away.
Any pics of what you are dealing with?
