Resinous screed for food industry

Substrate Preparation

Concrete substrates must be solid, dry, level, absorbent, and free from contamination such as oils, detergents, dust, or other substances. Newly installed screeds must be allowed to cure for the normal curing time. Evaluate the most suitable type of mechanical preparation: shot-blasting or milling. On old, deteriorated, or contaminated concrete floors, the surface layer must be removed until all loose or delaminated parts are completely eliminated, exposing open porosity and achieving a compact surface.

Application

1. Apply a coat of FLUIDEPOX with a roller at a consumption rate of 0.50–0.80 kg/m². On the same day, while the primer is still fresh, spread the mortar made of FLUIDEPOX and Quartz (grain size curve Mix1–Mix3), prepared in a suitable mixer (ratio 1:15). Use a squeegee and straightedge to distribute the mortar over the floor at a consumption rate of approximately 10.4 kg/m² (0.65 kg/m² of FLUIDEPOX and 9.75 kg/m² of Quartz). Compact using a power trowel with rotating blades.
2. Smooth and fill the pores with 1.0 kg/m² of FLUIDEPOX, applied using a smooth steel trowel.
3. Skim-coat the surface with PAVIPLAST, loaded 1:0.8 with Quartz B0, with a PAVIPLAST consumption of approximately 0.4 kg/m². Apply using a smooth steel trowel.
4. Apply a roller coat of FINISOL COLORATO LUCIDO polyurethane finish at approximately 0.13 kg/m².
5. Apply a second roller coat of FINISOL COLORATO LUCIDO at approximately 0.13 kg/m².
6. Cut the coating at the concrete joint locations and seal with SIGILFLEX polyurethane elastomer.

The resulting coating thickness is approximately 6 mm.

Covings

Before installing the coating, it is possible to create a cove at the wall–floor junction. For this operation, use PAVIRAPID SGUSCI, forming a curvature radius of approximately 4 cm. The cove is then covered with a skim coat of PAVIPLASTand FINISOL COLORATO LUCIDO.
