SCUMBLE FILLER · ART. 630
LEINOS 630 — a transparent, water-based decorative scumble-spatula for exclusive interior walls. Two to three translucent tinted passes with a Venetian trowel or Japanese spatula, then polished to a silk-gloss sheen. Breathable. Non-yellowing. Tinted on site with 668 Pigment Concentrate. Made in Germany by Reincke Naturfarben since 1985.
Decorative finish & Technique
A transparent scumble glaze in spatula form, not an opaque paint. Two to three thin translucent passes with a Venetian trowel or Japanese spatula, polished to silk gloss after a day. The colour lives in the layers, and the film stays vapour-open.
Once dry, 630 is a nearly colourless translucent glaze body. Two to three thin spatula passes — the same tint or deliberately different tints — build the tone-on-tone optical depth of true Venetian plaster that a single opaque coat cannot reach.
The binder is saponified shellac and natural-resin soap — water-based, plant- and lac-derived, non-yellowing. The same LEINOS chemistry family as 632 Effect Spatula and 635 Vintage Finish, here building a polishable translucent surface film.
Carnauba and beeswax in the compound take a lamb’s-wool-pad polish after roughly 24 hours — from soft matt to silk gloss. Optional 350 Wall Wax Finish deepens transparency and colour depth further, per the LEINOS technical sheet.
The cured film stays vapour-permeable — the wall keeps exchanging moisture with the room instead of sealing it behind a synthetic coating. A decorative polished-plaster register without giving up the open-pore wall physics of the LEINOS mineral line.
Where It Lives
Venetian-plaster feature walls — Mumbai, Bangalore, Delhi living rooms
The single statement wall in a premium apartment fit-out: layered tone-on-tone scumble behind the sofa line or the dining console. Translucent passes catch evening lamplight and daylight differently — the wall changes register through the day.
Boutique hotels and hospitality
Reception backdrops, lounge walls, corridor end-walls in boutique stays — Goa, Jaipur, Coorg. The silk-gloss polished finish reads as crafted plasterwork, not wallpaper. The breathable build suits the older masonry shells common in heritage-conversion properties.
Retail and brand interiors
Jewellery, fashion, and premium retail fit-outs where the wall is part of the merchandising light plan. The polished translucent plaster holds track lighting with a soft depth. Tintable to brand shades with 668 Pigment Concentrate.
Bedroom and dressing-room accent walls
Soft tone-on-tone depth at low evening light — the quietest register of the product. A single accent wall in a pastel 668 tint (half white concentrate + colour concentrate, per the LEINOS pastel recipe) over a prepared ground.
Entry foyers and lift lobbies of premium residences
First-impression surfaces with high visual value and low touch traffic. The polished wax surface takes ambient light from door glazing and lobby fixtures; 350 Wall Wax Finish adds protection where hands occasionally brush the wall.
Multi-tone layered compositions
The technique register: 2–3 passes in different shades — TDS-explicit — for designer-specified two-tone and tone-on-tone effects. Each pass dries 2–3 hours before the next; the composition is polished as one surface after 24 hours.

Read The Full TDSStep by Step
Check the substrate — chemically neutral, solid, dry, clean, grease- and dust-free, with no bleeding substances. LEINOS recommends trying the technique on a coated sample board first to judge the shade and spatula pattern before committing the wall (TDS tip).

Prepare the ground. Per leinos.de: level with LEINOS 684 Smoothing & Texturing Filler, then prime with 620 Deep Sealer diluted 1:1 with water — or alternatively apply an opaque coat of 660 Natural Resin Emulsion Paint for a finely textured ground. Room and surface temperature above 15 °C.

Tint the compound — stir in approximately 10% LEINOS 668 Pigment Concentrate for the target shade; for pastels use half white concentrate plus a colour concentrate (TDS recipe). The product is ready to use; no thinning is needed.

Spatula passes — apply the tinted compound thinly with a Venetian trowel (larger textures) or a Japanese spatula (stain technique). Minimum 2, preferably 3 translucent passes, in the same or different shades; each pass must dry before the next (recoatable after 2–3 hours).

Polish — after approximately 24 hours, polish the finished wall with a lamb’s-wool pad to a silk gloss. Work in even circular passes; the translucent layers tighten into a continuous sheen.

Optional wax finish — apply LEINOS 350 Wall Wax Finish for additional surface protection; waxing significantly increases the transparency and colour depth of the finish (TDS verbatim). Clean tools immediately after use with water and LEINOS 930 Plant Soap.

Full Declaration
Every ingredient declared on the label. The Trust Hub explains what each one does and the standards behind it.
Shellac + Natural-Resin Soaps (Binder)
Saponified shellac and natural-resin soap — the water-based, non-yellowing film-forming binder pair. The same LEINOS chemistry family as 632 Effect Spatula and 635 Vintage Finish; in 630 it builds a polishable translucent surface film. Methylcellulose holds the compound in working suspension.
Carnauba Wax + Beeswax
The polishable body — after approx. 24 hours the wax phase takes a lamb’s-wool-pad polish to silk gloss. The same wax chemistry that 350 Wall Wax Finish extends for deeper transparency and colour depth.
Mineral Body (Talc, Chalk, Clay)
Talc, calcium carbonate, and clay form the transparent spatula body that the Venetian trowel and Japanese spatula work into translucent layers. Tinted on site with approx. 10% 668 Pigment Concentrate. Inert, REACH-compliant minerals.
Preservative (Benzisothiazolinone)
Trace in-can preservative keeping the wet pail stable through shelf life. The TDS discloses 1,2-benzisothiazol-3(2H)-one by name; it may cause allergic reactions in sensitised individuals — sealed wet-handling hygiene applies. SDS available on request from LEINOS India.
