Frequently Asked Questions

Central Valley's intense heat and oil contamination break down standard sealers faster, causing premature cracking and fading. Premium sealers contain higher solids content that withstands temperature extremes and chemical exposure. Most commercial properties choose two-coat applications for extended protection against Valley conditions.

One coat provides basic protection while two coats create a thicker barrier against heat, oil, and traffic wear. Surface preparation with sweep and blow cleaning happens before either option. Two coats extend pavement life significantly in high-traffic or oil-exposed areas, which is why most customers choose that thickness.

Square cutting creates clean, geometric edges around damaged areas for a professional appearance and better compaction. Following crack patterns leaves irregular shapes that look patchy and allow water infiltration at jagged edges. The square-cut method uses more material but delivers neater, longer-lasting repairs.

Onsite measurements account for actual parking layout, slope variations, and existing features that standard templates can't address. ADA compliance requires precise spacing between accessible stalls, van spaces, and access aisles. Cookie-cutter approaches often miss site-specific requirements that create compliance issues during inspections.

The surface gets power swept to remove loose debris, then blown clean with high-pressure air to eliminate dust and fine particles. This preparation ensures sealcoat or paint bonds directly to asphalt rather than sitting on top of contamination. Skipping this step causes premature peeling and uneven coating thickness.

Temperature extremes cause asphalt expansion and contraction that widen cracks rapidly. Direct pour sealant application works best because it fills the full crack depth and flexes with pavement movement. Crack size determines filler selection—wider cracks need rubberized sealants while hairline cracks use different materials for proper adhesion.

Traffic paint contains glass beads for reflectivity and higher resin content that resists fading from UV exposure and abrasion from tires. Central Valley heat and heavy commercial traffic fade standard paint within months. Traffic-grade formulations maintain visibility and brightness significantly longer under these conditions.

Hot-mix requires heating equipment but compacts tighter and lasts longer because it bonds at the molecular level as it cools. Cold-patch works for quick fixes or small areas but doesn't achieve the same compaction. Large repairs and high-traffic areas benefit from hot-mix, while temporary or emergency repairs use cold-patch.

Valley sun and traffic wear fade parking lines within 12-18 months for most commercial lots. High-traffic areas near entrances and drive aisles fade faster, sometimes within a year. Oil field traffic and delivery vehicles accelerate wear compared to standard passenger vehicle lots.

Poor surface preparation, applying over oil stains, or coating during wrong temperature conditions cause early failure. Oil contamination prevents proper adhesion, and dust left on pavement creates a barrier between coating and asphalt. Applying when temperatures drop below 50°F or rise above 90°F affects curing and durability.

Water enters through cracks, softens the base layer, and creates potholes once freeze-thaw cycles or heavy loads break the weakened surface. Sealing cracks stops water infiltration before base damage occurs. A crack left unsealed for one Valley winter often becomes a pothole requiring full-depth repair by spring.

Surface oxidation, minor cracking, and fading indicate sealcoating will restore protection, while alligator cracking, sunken areas, or widespread potholes mean structural failure requiring replacement. If the base is stable and damage stays at the surface level, sealcoating extends life 3-5 years. Deep base failure won't improve with coating.
