QFM Group Ltd based in Sheffield are one of the UK’s leading Multi-site and Multi-brand franchise businesses called in PSC to refurbish the production floor area at new Dunkin Donunts facility at Blackburn (Blackburn is approximately 21 miles north-northwest of Manchester).
The client was looking for a hard wearing food grade flooring option. It was important that the floor be seamless and easy to keep clean. At the FREE site visit it was noted that floor area totalling 347 square metres, had extensive build-up of laytex, adhesive, mortar that would need to be removed before the final floor finish could be laid. It was recommended the final finish be a nominal 6mm RT polyurethane screed, with 100mm high polyurethane cove system.
In preparation it was necessary to remove the extensive build-up of laytex, adhesive, mortar and nominal 6mm of polyurethane screed, using small 320 planers, scarifiers, PCD disk grinders and the doubled headed diamond grinding machine.The edgework was then prepared with a totally enclosed handheld 110v diamond grinder and the area was vacuumed clean of all residues and dust.
10mm x 10mm saw cuts were made to door thresholds, around drains and gullies and perimeter of floor area and where necessary to toe in and anchor screed. Repairs were made to damaged concrete, where walls have been knocked out, using polyurethane mortar compound and holes and damaged concrete repaired in the former KFC section, totalling circa 100 square metres, using polyurethane mortar compound and resin screed.
Finally, 6mm aluminium movement joints were fitted to all door entrances and where necessary.
A nominal 6mm heavy duty Resedv Pumadur RT polyurethane, textured, matt screed was laid in the clients chosen colour – mid grey, to existing concrete contours and to 6 stair treads. Existing expansion joints were recut, knocked out and infilled with matching jointing compound and one coat of Resdev, Pumadur DD polyurethane seal coat, clear, silk was applied.
Finally 100mm high, 50mm radius Coving system was installed to 244 linear metres including to 7 upstands, circa 200mm high using Resdev Pumadur CG polyurethane coving system.
The client was pleased to see we completed the project on time and within budget.
