Temporary theatre blackout in Deptford

Project Challenges and Solutions

Removable blackout requirement
The brief called for full light exclusion without permanently altering the building fabric. To achieve this, the skylights were prepared with a peelable base coating before a high-build vinyl topcoat was applied to create the blackout effect. The system was selected to provide blackout during the theatre period and allow later removal.

Coverage and colour depth
Because the selected finish was lighter than a standard black blackout coating, the skylights required careful build-up to stop light transmission. Multiple coats were applied methodically until the team achieved complete, even coverage across each pane.

Working at height
The skylights followed a sloping roof line, with working heights ranging from roughly 9m to 15m. IPAF-trained operatives used scissor lifts to reach the full surface safely and maintain consistent application across the angled sections.

Three-day programme
The theatre fit-out schedule left only a short window before equipment installation began. A ten-person team worked extended shifts over three days, allowing preparation, coating and inspection to be completed without compromising the finish.

Health and safety
Spraying at height in a large warehouse environment required tight controls. RAMS were agreed before work started, with appropriate PPE, respiratory protection, access planning and daily briefings in place throughout the project.

Process

The team began by preparing the work area, setting out access equipment and confirming the safety plan. Once the skylights were ready, a peelable base layer was applied to support later removal. The blackout coating was then built up in controlled passes, with the spray technique adjusted for the roof angle and the scale of the glazing.

After application, the team carried out light checks and a final inspection to confirm the skylights were fully blacked out. The work was completed within the agreed three-day window and handed over ready for the temporary theatre installation.

Results

The warehouse was transformed into a theatre-ready space with complete daylight control through the skylights. The coating system delivered the required blackout effect and was specified for removal after temporary use. The project was completed safely, on time and under a demanding programme, with the client receiving a clean, practical solution for a temporary venue.
