Parking lot marking prep starts with the surface underneath

A herringbone StreetPrint pattern went into a commercial frontage in Mission in April 2025, grey-on-grey stamped asphalt sealed in StreetBond 150 Pewter. The finished surface looks like it was always meant to be there. What made that possible was the condition of the asphalt before the stamp went down, and the prep work that got it ready.

If you're planning decorative markings for a parking lot in BC, the surface underneath is where the job starts. Parking lot marking prep determines how the work bonds, how it wears, and whether it stays put under traffic.

How Square One prepares a surface

The rig that cleans a lot before marking is mobile across the Lower Mainland and Vancouver Island. Vapour blasting is how Square One primes surfaces for its own coating and thermoplastic installs, and it is offered on its own for road-marking removal, graffiti, mould, paint and stain stripping.

Vapour blasting uses less water than pressure washing, produces up to 92% less dust than dry blasting, and puts little to no heat into the surface. That matters for asphalt: high heat softens the binder, and excess water can saturate cracks that need to stay dry for repair. The process removes old road markings, gum, soot and stain from concrete, steel and wood.

For a lot that already has painted lines or faded markings, vapour blasting strips them cleanly. The preformed thermoplastic sheets that Square One installs are heat-fused to the pavement in place, to the manufacturer's published specification. A clean, sound substrate is what lets that bond hold under delivery trucks and daily turns.

What the lot needs before markings go down

A brick-pattern walkway across a parking lot moves pedestrians where you want them and tells drivers to expect them. Square One builds thresholds, entrance aprons, walkways and crosswalks for retail centres, strata and commercial sites. The systems include StreetPrint stamped asphalt for the pattern, StreetBond for colour and grip, and preformed thermoplastic: TrafficPatternsXD for crossings, PreMark for arrows and accessible-parking symbols, DecoMark for a logo at the entrance.

The record runs from retail centres and townhouse lots to high-visibility walkways and parkade markings. What these jobs share is that the asphalt or concrete was ready to receive the work. For a lot that is sound but tired, DuraShield is the maintenance coating, in black or Solar Gray. For a lot with structural problems (heaving, alligator cracking, soft spots) those repairs belong to the paving contractor before decorative work begins.

The site walk and what it covers

A job starts with a free site walk with the sample boards. Square One looks at the substrate, the traffic and the layout against the owner's marking standard before anything is cut. That walk is where the condition of the existing surface gets assessed: whether it needs vapour blasting, whether old markings need removal, whether the pavement itself is sound enough to hold the new work.

The manufacturer's design manuals, custom design guidelines, colour palettes and specifications for each system are in the specification library for the spec package. The written quote sets out the system, the colours and the layout.

What to settle before you book

If you're specifying decorative markings for a parking lot, these are the questions to answer first:

• Is the existing pavement structurally sound, or does it need repairs before marking?
• Are there old markings, paint or staining that need removal?
• What is the traffic load, and does the lot close at night for phased work?
• Does the owner have a marking standard, or will colours follow a standard palette?

Where a street cannot close, the work is phased. The Little Italy crossings on Commercial Drive went in intersection by intersection, in overnight blocks. A parking lot often has more flexibility, but the approach is the same: plan the closure, prep the surface, and the markings go down fast.
