Warehouse with white painted steel columns, open ceiling and concrete floor.

Spray painting for working buildings

Warehouse interior with white painted steel beams, columns and exposed roof deck.

Warehouses, factories and open ceilings

Refresh large wall areas, exposed roof decks, joists, beams, columns and suitable overhead services with a consistent spray finish. We review the existing coating, cleaning, corrosion, primer and lift access before choosing the application method. Sprinkler heads, detectors, labels, lights and equipment that must remain unpainted are protected.

Offices, shops and commercial interiors

Wall and ceiling painting, doors, frames and durable finishes for office suites, stores, common areas and tenant turnovers. Spray, brush and roller work are planned around the surfaces and the business. We agree on work zones, masking, ventilation, drying time and reopening before work starts.

Dry fall ceiling painting

A cleaner, brighter open ceiling

Dry fall coatings suit many commercial and industrial open ceilings, including compatible metal decking, joists and exposed services. White can brighten the space; darker finishes can make overhead structure recede. Substrate compatibility and any required primer are checked first.

Overspray control still matters

Dry fall overspray is designed to become removable dust after enough fall distance under the product’s stated conditions. Ceiling height, air movement, temperature and humidity affect that behaviour. Floors, stock, vehicles and equipment still need protection, followed by cleanup.

Existing fireproofing needs a separate review

Dry fall is a decorative coating, not structural steel fireproofing. Existing intumescent or textured fireproofing must be identified before cleaning or repainting. We do not cover, disturb or repair it without the required system review and compatible approved materials.

Commercial exterior painting

Warehouse exterior with charcoal metal cladding, pale masonry and painted loading doors.

Cladding, masonry and loading areas

Exterior spray painting for suitable metal siding, concrete block, stucco, loading doors, entrance frames, railings and bollards. The scope defines washing, loose coating removal, corrosion preparation, primers and finish coats. Wind, surface temperature, moisture, dew point and weather windows guide spraying and curing. Deliveries, entrances, neighbouring vehicles and public access are planned around the work.

Fire rated coatings for structural steel

Intumescent fire protection

Intumescent coatings expand when exposed to fire to help insulate structural steel. We review projects for specified application to beams, columns and other identified members. The required fire resistance comes from the tested assembly and approved design, not a general coat count or a paint colour. Project acceptance depends on the specified system, applicator requirements and inspection arrangements.

The right system before spraying

The design identifies the steel members, required rating and coating thickness for each applicable profile. Surface preparation, compatible primer, intumescent coats and any required topcoat must follow that system. Thickness cannot be guessed from a similar beam, and additional coats must remain within the permitted limits.

Thickness checks and corrective coats

Wet film checks guide application. After drying, dry film thickness is measured with a calibrated gauge and recorded against the specified requirements. Where readings are below the accepted limits, the affected areas receive corrective coats within the system’s recoat and thickness limits, then dry and are measured again. Inspection hold points and access are agreed before work starts.

Inspection and handover

Coordinate the required independent inspection and acceptance with the project team and authority having jurisdiction. Handover includes the agreed product records, steel member references, application conditions, thickness readings and repair or reinspection records. Final acceptance is by the responsible inspector or authority, not a promise made by the painter.

Which sprayed coating does your building need?

Decorative dry fall

A finish for suitable exposed ceilings and services. It changes appearance and may improve light reflectance, but does not establish a structural fire resistance rating.

Intumescent coating

A relatively smooth coating system used where the approved design calls for fire protection of structural steel. It needs documented preparation, application, thickness verification and acceptance.

Textured spray fireproofing

Thick, rough coatings on warehouse steel may be cementitious or mineral fibre spray applied fire resistive material. These are a different scope from intumescent painting, with their own thickness, density, adhesion and inspection requirements. Send a photo and we can review which scope is needed before quoting.

From site review to finished surfaces

1. Tell us what needs painting

Start with the building location and the surfaces you want painted. Photos, approximate area, ceiling height and preferred work hours are helpful when available. You do not need to choose the technical coating system to make an inquiry.

2. Review the site and written scope

We review preparation, coating systems, access equipment, protection, ventilation and business operations. For fire protection work, the approved design, member schedule and inspection requirements are confirmed before application. A requested visit is arranged with you before it is confirmed.

3. Prepare, coat and check

Complete the agreed preparation and application, allow the required drying and curing, check the specified finish and clean the work zone. Fire protection work includes the required records, corrective work and inspection stages before handover.

A quote that fits the building

Defined surfaces and preparation

Identify the walls, ceilings, steel, doors and exterior details included in the quote. Cleaning, rust removal, repairs, primer, finish system and inspection responsibilities are written into the scope rather than left as assumptions.

Work planned around your operation

Discuss phased areas, shutdown windows or work outside business hours where practical. The plan accounts for lifts, loading access, stock, equipment, ventilation and safe return to use. Schedule and price follow the site review.

    Max and his team at Strataline have done multiple home improvement projects for us, including stair refinishing, popcorn ceiling removal, new flooring and interior painting. From the start their team was professional and punctual.

    The Popcorn removal was excellent and a very clean process. They also transformed our stairs from boring oak to a much more modern look. They handled repainting of the whole house and replacement of old tile floors with a beautiful new one.

    We had an excellent experience working with Maxim and Strataline Inc. Installing and perfectly matching a custom stain for our oak treads was no small task, and the addition of the square posts made it an even greater technical challenge—but everything was executed flawlessly.

    Maxim at Strataline did a very professional job in removing our hallway popcorn/stucco ceiling. The end result was a completely smooth surface and not only that, they totally sealed off the area so absolutely not dust penetrated other areas of the house.
