UV-cure acrylate (1K, 100 % solids roller materials) over a tintable low-solids UV primer; optional water-based dye (CTH)

Parquet finishing (UV-cure roller line)

Substrate
Parquet and engineered flooring (solid or veneered hardwood), flat boards on a UV roller-coating line
Result
A clear (optionally tinted) closed-pore floor finish, satin 30–40 gloss, highly abrasion- and scratch-resistant; ready to pack straight off the line.
  1. 01

    Sanding the bare wood

    Abrasive: P150, P180, P220

    Belt-sand in three grits, then de-dust thoroughly. Wood moisture 8–10 % (standard parquet practice, not stated in the schedule).

    Pressure
    n/a — set coat weight by roller gap/pressure and line speed (10 m/min)recommended

    A thin penetrating coat from a smooth applicator roller. To colour the floor, stir in 5–10 % CTH water-based dye (the base shades intermix), mix well and check the shade on a test board. Don't exceed 10 % — intercoat adhesion suffers. This coat is never sanded.

    CTH: 5.0 % — fixed by the datasheet

    Ratio 100 : 5.0

    CTHAdditive23.8 g
    Total500 g

    Covers roughly 62.50 m² at 8 g/m².

    Pot life of the mix: n/a — no hardener; once tinted with CTH, use the same shift and keep out of daylight/UV.

  3. 03

    Forced drying

    Drying: [object Object] °C

    Drying without a UV lamp (warm-air/IR tunnel). The coat must be tack-free before the filler goes on, otherwise water from the dye is trapped under the UV build (whitening, delamination).

    Use a filler (reverse/doctor) roller to pack the grain and strip the excess. Catalog: doesn't attack stains — the colour from step 2 is not lifted.

  5. 05

    UV cure

    One lamp only — a partial (gel) cure so the next sealer coat bonds chemically.

    Thin coat from a smooth roller. VTS20015 has no product page, catalog entry or dealer listing — this schedule is the only source.

  7. 07

    UV cure

    Gel cure with one lamp.

    Clear, flexible, abrasion-resistant sealer; doesn't whiten or delaminate when the board flexes (catalog).

    Second pass of the same VTS20002 sealer.

  11. 11

    UV cure

    Three lamps — full through-cure of the whole sealer build before sanding.

  12. 12

    Sanding the sealer build

    Abrasive: P240, P280, P320

    Sand only the fully cured (3-lamp) build and don't cut through to the tinted coat. De-dust before the topcoat.

  13. 13

    Topcoat lacquer (two passes)

    Pressure
    n/a — set coat weight by roller gap/pressure and line speed (10 m/min)recommended
    Consumption
    8 + 8official

    Smooth applicator roller, two thin 8 g/m² passes — better levelling and a more even sheen than one heavy coat.

  14. 14

    UV cure

    Final full cure under three lamps. Boards can be stacked/packed as soon as they cool.
