Can you put 6mm food grade flooring on top of tiles?

In all cases it is always best to be laying a polyurethane resin screed system down directly on to the concrete substrate. However, if you are faced with needing to lay epoxy resin on quarry tiles, then as long as they are solid, it shouldn’t be an issue. The deciding factor is always the stability of the substrate – it is imperative that the substrate is not breaking away or flexing.

In order to create a good bond with tiles it is recommended to lay a DPM Epoxy resin primer. Also, incorporating a heavy scatter of 0.6 to 1.2mm quartz aggregate. The DPM Epoxy resin primer helps the final 6mm?RT polyurethane resin screed?system to bond with the tile substrate. On the other hand, the heavy scatter of 0.6 to 1.2mm quartz aggregate helps to grip the 6mm RT polyurethane resin screed system to the DPM.

When would it not be appropriate to lay 6mm food grade flooring on top of tiles?

It would not be appropriate to lay 6mm?food grade flooring on top of tiles?if the tiles were not solidly stuck to the substrate. It is imperative that the substrate is not breaking way or flexing in any way. If it is, it would cause the 6mm?RT polyurethane resin?screed system to potentially crack if the substrate flexed and the 6mm was put under pressure.

90 Square Meter Food Grade Flooring onto Quarry Tiles

PSC have recently completed 90 square meters of 6mm?RT polyurethane resin screed?system (Food Grade Flooring) onto Quarry tiles in a commercial kitchen for The Speech House Hotel, Royal Forest of Dean. It was noted at the site visit that the kitchen had a layer of sheet vinyl with the quarry tiles beneath.

Client Brief & Recommendation

The client was looking for a?food grade, seamless, hard wearing, impact resistant, chemical resistant, anti-slip resin floor that would last 10 years plus. Therefore, it was recommended that a DPM Epoxy resin primer was laid before a 6mm Resdev Pumadur RT polyurethane resin screed system. And as with all commercial kitchens the 6mm be finished off with 100mm high matching coving.

6mm Food Grade Resin Screed System – The Preparation

In preparation the layer of sheet vinyl was uplifted, exposing a layer of latex and adhesive on top of the quarry tiles. This was removed using diamond grinding machinery. After that, we vacuumed clean of all residue and dust. 6mm x 10mm saw cuts were then made to the door thresholds, around drains, gullies and perimeter of floor area and where necessary to toe in and anchor the screed.

90 Square Meter 6mm RT Heavy Duty Polyurethane Screed

An DPM Epoxy resin primer with a heavy scatter was laid before a 6mm Resdev Pumadur RT?polyurethane resin screed?was laid in the clients chosen mid grey. The floor was complemented by 50 linear metres of 100mm high CG polyurethane coving system.

Gill Hands – Director of The Speech House Hotel commented: “The food grade flooring system that PSC Flooring have installed has transformed our commercial kitchen.”

Completed on time and within budget this transformation speaks for its self.
