FL701 Floorcoverings – Vinyl Sheet

Preparation:

1. Substrates must be firm, clean, dry, and sound. Substrates and subfloors must be free of grease, oil, wax, curing compounds, high levels of moisture (hydrostatic pressure), loose material, paint and any other contaminants. New concrete must be cured for a minimum of 28 days.
2. Thoroughly vacuum loose material and dust.
3. If mechanical preparation is required, prepare the floor using the recommended methods as advised by the substrate manufacturer.
4. For concrete floors, moisture content and relative humidity tests should be conducted prior to installation.

1. Vinyl installation shall be in accordance with AS 1884 Floor Coverings – Resilient Sheet and Tiles – Installation Practices.
2. Apply Uzin PE 460 epoxy moisture barrier if the relative humidity test shows moisture above 80%, or hydrostatic pressure / rising dampness is present or of concern.

   Uzin PE 460 is an epoxy damp proof membrane with low odour, mainly used as a moisture barrier up to 98% R.H. on cementitious screeds or concrete. For interior and exterior use.

3. Apply Uzin PE 280 fast-drying primer on all non-porous substrates, including over Uzin PE 460 once dry.

   Uzin PE 280 is a super-fast, film-forming primer, for use on dense and smooth internal substrates.

4. Apply Uzin PE 260 on all porous substrates.

   Uzin PE 260 is a dispersion-based primer that can be diluted. For use on dense and absorbent substrates, mainly for subsequent installation of smoothing compounds.

5. Where required on uneven surfaces, install Uzin NC 160, Uzin NC 170 Levelstar or Uzin NC 196 on primed area/s, depending on depth requirement and/or curing time constraints.

   Uzin NC 160 is a self-soothing compound for all types of floor coverings as well as wood flooring for thicknesses from 0 to 20 mm.

   Uzin NC 170 Levelstar is an extremely smooth and quick-setting cementitious smoothing compound with excellent flow properties.

   Uzin NC 196 is a fibre-reinforced smoothing compound for thicknesses from 3 to 40mm.

6. Install Uzin NC 182 NEW repair mortar, where additional ramping is required.
   Uzin NC 182 NEW is a moisture-resistant, low-slump and rapid internal repair mortar with reActivate effect for any range of thickness.
7. If any additional smoothing is required, Apply Uzin NC 888 S to primed surfaces.

   Uzin NC 888 S is an ideal material for repairing minor imperfections, holes, trowel marks, skim coating and ramping. It can be applied by trowel from a true feather edge up to 4 mm depth in a single application.

8. Install preformed cove fillet, and flat or feather-edged PVC skirting using Uzin U-Tack.

   Uzin U-Tack is a multi-purpose adhesive tape for securely installing different types of skirting and floor covering strips.

9. Once the levelling compound has cured, apply a layer of Uzin KE 2000 S or Uzin KR 430 with a notched trowel. Ensure to apply only the amount of adhesive that can be covered within the open time.

   Uzin KE 2000 S is a strong dispersion adhesive with a short waiting time and long working time. It can be used as a wet-set adhesive. For use on internal floors and walls.

   Uzin KR 430 is a two-part polyurethane adhesive for all resilient flooring types, with extremely high final strength and for use in areas of extremely high traffic.

10.  Install the vinyl sheet into a wet film of adhesive and dry roll on top of the vinyl sheet in a cross-hatch motion to ensure the adhesive transfers onto the backing of the sheet vinyl.
11.  Ensure all sheet junctions are heat welded together and excess weld rods are trimmed to finish flush with the vinyl sheet.
