Large-area commercial refurbishment where substrate condition, access, detailing, weather and operational constraints support a specialist spray route.

Two-component commercial spray system
Blackburn combines domestic flat roofs and extensions with older industrial and commercial roof stock around Blackburn and Darwen. The first split is therefore small-roof material supply versus survey-led commercial repair or refurbishment.
Direct answer
SprayGrade is a two-component, water-based spray-applied liquid rubber system for suitable large commercial and industrial waterproofing projects. Project delivery is supported through trained approved contractors.

Large-area commercial refurbishment where substrate condition, access, detailing, weather and operational constraints support a specialist spray route.
A survey should confirm roof condition, substrate compatibility, drainage, preparation, access, containment and the correct primer or build-up.
Do not infer suitability from roof area alone. Wet or frozen substrates, unsound roof fabric, uncontrolled access or incompatible existing coatings must be resolved first.
System separation
Typical application output is approximately 600m² per day under suitable conditions; roof geometry, preparation, access and weather can materially change delivery. The figure is not a completion promise.
Complete project scope
Map substrate, moisture, drainage, defects, fragile areas, rooflights and operational constraints.
Define cleaning, repairs, primer, reinforcement and treatment at every change of material.
Set safe access, equipment location, containment, weather limits and phasing before mobilisation.
Control specified consumption, details, continuity and project records rather than relying on headline speed.
On older industrial roofs, investigate laps, fixings, rooflights, gutters and previous coatings as one connected water-management system. On domestic flat roofs, confirm deck condition, drainage and edge details before choosing a membrane.
For commercial premises in Blackburn and Darwen, record the roof covering, substrate, drainage route, access and whether operations must continue below the work.
