Premfloor were awarded the prestigious contract of installing a three colour resin terrazzo to the new LEGO® flagship store in Leicester Square. This was a rapid fit out working in tandem with multiple teams of contractors, in an enclosed area (tight on space). We designed & sourced the resin system in-house, after agreeing samples with the client.

We were given a yellow, light grey and dark grey tile to match against. Precise colour matching took around 3 weeks, the yellow proving particularly challenging since it contained different sizes of yellow glass. Walls and countertops were also yellow, so a uniform colour matching was critical.
Heavy duty traffic including forklifts and scissor lifts caused severe damage to the sand-cement screed. We repaired it using epoxy resin screeds and fibre bandages. The entire surface was strengthened with a penetrating pure epoxy resin.
Prior to starting Premfloor conducted thorough sitewide moisture tests. It was agreed with the client that a DPM would be required before installing any epoxy coating on the project. This was done alongside repairing any cracks, holes and problems with the screed.
Using lasers and working from client drawings, we installed metal colour divider strips. The design called for dark grey borders with light grey and yellow fields on either side.
The dark grey borders were laid firstly, forming the perimeter for the yellow and light grey fields. All the poured terrazzo was hand-laid.
We opted for 3 phase HTC floor grinders & ermator vacuums for the majority of grinding. The upstairs area was around 300m2 with 3 colours and required 3 days of careful grinding.
Each colour of floor was grouted in a liquid colour matched epoxy resin, and marble dust. It was trowelled across the floor filling all pin-holes. Air movers were utilised due to high internal temperatures during this phase.
Following several polishing stages, we sealed with multiple layers of sealer, finishing with a light-stable polyurathane. This offered both UV and chemical resistance, and colour enhancement.
Buffing was carried out with a high speed burnisher, armed with special pads. Reflection of the lighting modules can clearly be seen in the floor.
