Ever watch someone spend a Saturday painting a fancy coat over a crumbling mess, only to see it peel right off by the next snowstorm? Sealcoating looks simple from the curb, but doing Asphalt Sealcoating right takes more than just pouring black liquid out of a bucket. Up here near the lake in Bigfork, MT, where our weather swings from baking summer sun to freezing winter snowpack, cutting corners on surface prep or product choice means your driveway will not last two seasons.
Here are the common issues Pacific Asphalt sees homeowners trip over time and time again when planning an Asphalt Sealcoating project, and how you can save yourself trouble.
Skipping the Crack Fill and Deep Cleaning
The biggest mistake is treating sealcoat like a magic eraser. If you have cracks spiderwebbing across your pavement, rolling a fresh layer of sealer over them will not fix a thing. Water gets down into those gaps, freezes during our brutal winter nights, and expands. If you seal right over dirt, oil spots, or loose aggregate, the material loses its bond. At Pacific Asphalt, we always stress that surface prep accounts for half the job. You have to blow out the debris, scrub out the oil slicks, and lay down a proper hot-pour or cold-pour crack filler before a single drop of sealer goes down during Asphalt Sealcoating.
Falling for Cheap, Diluted Products
You get what you pay for. Those ultra-cheap drums sitting in the big-box store parking lot in the Flathead Valley are usually watered-down emulsions that contain mostly filler and very little actual asphalt binder. They wear away after a few heavy rains or get scuffed off the first time you crank your steering wheel while backing out of the garage. A professional-grade sealer needs to form a tough shield against UV rays and chemical spills like gas or antifreeze. Do not look for the absolute lowest bid on your Asphalt Sealcoating project, or you will find yourself doing the whole job again next summer.
Timing It Wrong with Montana Weather
Timing means everything around here in Bigfork, MT. If you try to sealcoat too late in the fall when the overnight temperatures plunge toward freezing, the emulsion will not cure correctly. It needs sustained warmth and low humidity to set up a proper chemical bond. Try to get Asphalt Sealcoating done during a stretch of steady, dry weather, and pay attention to morning dew points. Slapping down sealer on damp asphalt or under a threatening cloud ceiling is a guaranteed recipe for failure.
Ignoring Drainage and Grade Issues
Sealcoating locks out moisture, but it does not fix a puddle problem. If your driveway sags in the middle or water pools near your foundation, sealing right over it just traps that moisture underneath the top layer. Make sure you address any sub-base pooling before you worry about the cosmetic finish of your Asphalt Sealcoating.
