Polyurethane molding NPU-436.1L

Polyurethane molding NPU-436.1L — left-sided decorative element for moldings with dimensions 85 × 34 × 16 mm. Made of two-component polyurethane, designed for corner joints, end points, and decorative transitions in molding systems. NPU-436.1L is compatible with moldings MLDPU-002 и MLD-002-MG — direct factory compatibility, confirmed by the manufacturer. Price from 660 rubles per piece, shipping from one unit, delivery across all of Russia.

Three things determine the choice of decor for moldings: article number, size, and compatibility with a specific profile. NPU-436.1L covers all three positions at once. If you are already working with moldings MLDPU-002 or MLD-002-MG and looking for a corner accent for this system — this is exactly about it.

NPU-436.1L molding decor: what this element is and what it is for

Among all categories decoration for moldings corner accents hold a special place. These are not independent decorative elements that work on an open wall, nor are they profile moldings that run along the perimeter. Corner accents exist exclusively within a system: they give the molding structure completeness, place architectural accents, and turn a set of profiles into a cohesive decorative composition.

NPU-436.1L is precisely such a corner accent. A left-sided element with a floral ornament, which is mounted in the left corner zone of a framed panel or at the left end point of a molding line. The letter L in the article number means Left — left-hand version. For the right side of a symmetrical system, the manufacturer offers a paired element NPU-436.1R. In framed panels, both article numbers are used in equal quantities — one in each corner of the corresponding side.

Format 85 × 34 × 16 mm — one of the largest in the series of decorative tips for medium-width moldings. Length of 85 mm gives the ornament space for full deployment. Width of 34 mm creates a pronounced expansion relative to the main molding profile width of 22 mm. Relief of 16 mm — the deepest in the range of products of this type: with side lighting, its shadow falls for several centimeters, making the element visible and expressive even in spacious rooms with high ceilings.

The floral ornament of NPU-436.1L reproduces living natural lines — smooth curls and leafy motifs characteristic of hand-carved wood. This is not mechanical embossing with identical repeating units, but an ornament with rhythm and movement, in which each element of the pattern organically flows into the next.

Fits moldings MLDPU-002 and MLD-002-MG

Compatibility is the key commercial parameter of the NPU-436.1L card. This is not selection by approximate size or a stylistic suggestion. Manufacturer STAVROS directly indicates the pairing in the catalog on the page decor for MLDPU-002 moldingNPU-436.1L is the recommended decorative element for this molding system.

Molding MLDPU-002: polyurethane profile 22 × 11 × 2600 mm

Molding MLDPU-002 — a decorative profile made of two-component polyurethane with a cross-section of 22 × 11 mm and a strip length of 2600 mm. Its 22 mm width places it in the medium-width molding category: noticeable enough for independent application and delicate enough for use within multi-contour frame systems. A profile with pronounced relief, classic stepped edges, and a central decorative element — one of the basic profiles in the STAVROS range for wall frame systems.

MLDPU-002 is made from the same two-component polyurethane as NPU-436.1L. During final painting, both elements behave identically: they accept paint evenly, without differences in tone or surface texture. The system looks monolithic — like a single architectural solution, not a set of separate parts.

Molding MLD-002-MG: primed MDF 22 × 11 × 2600 mm

Molding MLD-002-MG of the Prestige series — an analog of MLDPU-002 made from primed MDF with the same parameters 22 × 11 × 2600 mm. The material is manufactured by hot pressing at a temperature of 180–220°C and pressure of 30–40 MPa — dense, homogeneous, without voids or defects. Factory priming is applied using an automated method: uniform layer thickness across the entire surface of the profile, including relief areas. MLD-002-MG is delivered to the customer fully ready for final painting.

Paired with the polyurethane NPU-436.1L, the system is painted in a single finishing layer. An important practical point: when joining the ends of MLD-002-MG, a 0.5–1 mm gap is left, which is filled with elastic acrylic sealant matching the color of the finish. After sanding, the joint becomes invisible.

Proportional logic of compatibility: why the dimensions work exactly this way

The width of NPU-436.1L is 34 mm, which is 12 mm wider than the MLDPU-002 molding (22 mm). This ratio of 1.5:1 is standard in classical architecture for the relationship between the corner accent and the main profile. The corner element is wider than the molding: it visually anchors the corner, marks the break point of the line, and establishes the scale for the entire framing system.

The relief of NPU-436.1L is 16 mm, which is almost one and a half times greater than the height of the MLDPU-002 molding (11 mm). The corner accent protrudes above the plane of the molding line, creating a hierarchy of volumes: the profile serves as the background, and the corner element serves as the accent. This hierarchy is unmistakably clear under any lighting conditions.

Product Characteristics

Advantages of NPU-436.1L polyurethane decor

Two-component polyurethane: a material with a dual-layer density

STAVROS manufactures polyurethane decor using the reaction injection molding method in closed pressure molds. This technology creates two density levels in a single product: the inner layer, comparable in characteristics to pine wood—lightweight and easy to work with—and the surface layer, several times denser—durable and resistant to mechanical impact. This is why NPU-436.1L is both easy to install and durable in use—two properties that are often contradictory in most materials.

Impact resistance without chipping or deformation

Corner decorative accents of molding systems are placed in visible areas and in zones with an increased risk of accidental mechanical impact—corners of frame panels, edges of door reveals, ends of horizontal belts. Polyurethane with a density of 300–330 kg/m³ does not chip during installation, does not crumble at corners upon accidental impact, and maintains its geometry during long-term use. The fine details of the NPU-436.1L floral ornament do not break off during transportation or while working with the product.

Moisture resistance with no restrictions on room type

Polyurethane is chemically neutral to water: it does not absorb moisture, does not swell, and does not deform with humidity fluctuations. Decor for polyurethane moldings It is not susceptible to rot or mold formation, which guarantees a long service life and preservation of appearance. NPU-436.1L performs equally reliably in a living room with central heating and in an entryway with an unstable microclimate. The temperature range for geometric stability is from -40°C to +50°C.

Detailed relief with lively ornament lines

The production history of STAVROS is linked to the restoration of historical palace interiors. The company's master molds are created with the same precision used when working with original architectural carvings. The floral ornament NPU-436.1L is not a mechanical repetition of the same module, but an ornament with rhythm: each curl organically flows into the next, creating a sense of living movement. With a relief of 16 mm and proper side lighting, this effect is especially expressive.

Light weight: installation without substrate limitations

NPU-436.1L weighs a few grams. This means complete freedom in choosing the substrate: drywall without reinforcement, MDF, OSB, concrete, brick — on any prepared surface, the product holds securely with mounting adhesive without additional mechanical fasteners. The lightness also simplifies work at height and allows adjusting the element's position until the adhesive fully sets.

Ready for painting

The surface of NPU-436.1L is smooth and uniform, without pores or flash. The product accepts water-based, acrylic, and alkyd paints. In the system with the primed molding MLD-002-MG, both elements are painted in a single finish coat — no discrepancies in tone or texture, a monolithic result. In the Prestige version, NPU-436.1L comes with factory hand sanding and does not require preliminary matting before the finish enamel.

Ecological Safety

STAVROS polyurethane products do not contain toxic fillers and are safe for living spaces, including children's rooms and bedrooms. The material does not emit chemical vapors during operation under normal conditions.

Visual features of NPU-436.1L

Large corner accent with an elongated ornamental field

The length-to-width ratio of NPU-436.1L is approximately 2.5:1 (85 × 34 mm). This is an elongated corner accent that, when installed in the corner of a frame panel, creates a pronounced decorative movement: the ornament visually 'flows' from the horizontal plane of the molding into the vertical, linking the two directions of the system into a single whole.

16 mm relief — the most prominent in the range of angular accents for medium-width moldings. Under direct overhead lighting, the element reads as a three-dimensional sculptural detail. With side light from a wall sconce, the relief's shadow falls 2–3 cm downward, creating depth characteristic of natural stone or wood carving. In rooms with ceiling heights from 2.8 m and molding system lighting, this effect becomes an architectural statement.

Floral ornament: a natural motif with a classical foundation

Ornamental theme NPU-436.1L is floral. Smooth swirls, leaf motifs, organic curves — all hark back to the language of classical architectural carving used in European interiors of the 17th–19th centuries. In a contemporary context, this theme works in several stylistic environments:

• Neoclassical — the primary environment, molding frame systems with ornamental accents
• Classical — rich decorative systems with multiple molding contours
• Provence — natural motifs are organic to this style, NPU-436.1L creates the desired liveliness
• Transitional style — when an interior combines classical lines with contemporary restraint

In minimalist and contemporary interiors, NPU-436.1L is used as an intentional contrasting accent — a point of decorative concentration against clean planes.

Where to use decorative element NPU-436.1L

Corner nodes of framed wall panels

Direct and primary application. Frame decorative panels made from MLDPU-002 or MLD-002-MG moldings form rectangular contours on walls of living rooms, hallways, studies, and bedrooms. At each corner node of such a system, NPU-436.1L (left) and its paired element NPU-436.1R (right) create a decorative corner lock. Without these elements, the system looks technically precise but architecturally incomplete. With them — it achieves the professional finish that distinguishes a designer interior from a DIY renovation.

Endpoints of molding horizontal lines

A decorative belt made of MLDPU-002 molding at a height of 90–100 cm from the floor, a horizontal molding line along the wall separating finishing materials — wherever the molding ends not in a room corner but at a free point, decorative finishing is required. NPU-436.1L at the left endpoint and its paired right counterpart at the right point close these ends, giving the system intentional completeness.

Door and Window Trim Finishing

Molding architraves based on MLDPU-002 are a popular technique for decorating door and window openings in classic interiors. The side posts of the architrave end at the upper corner point by intersecting with a horizontal crossbar. NPU-436.1L finishes this corner joint, giving the architrave a professional architectural character.

Classic-style furniture fronts

Cabinet door panels, kitchen facades in classic style, furniture decor elements — all these surfaces use 22 mm wide moldings. Decor for polyurethane moldings In corner joints of furniture facades, it gives the product joinery detailing: it is precisely the corner accents that distinguish handmade furniture from mass production. NPU-436.1L in this system creates the required level of ornamental concentration at key points of the facade.

Representative commercial facilities

Receptions, meeting rooms, banking halls, restaurants, private clubs with classic decor — commercial facilities with representative requirements for interiors. Polyurethane decor for NPU-436.1L moldings ensures repeatability of results when installing large volumes: all items from a batch are identical, do not require fitting, are installed quickly and predictably.

Systems with corner blocks MLDPU-002U

In molding systems based on MLDPU-002, it is often used corner block MLDPU-004U — a square corner element for right angles of frame panels without cutting the molding at 45°. In systems where MLDPU-002 serves as the base and corner blocks provide right-angle turns, NPU-436.1L is used as an additional decorative accent at key points of the system — at the ends of horizontal lines and at nodal points of multi-contour panels.

Installation and selection recommendations

Required tools and consumables

• Mounting adhesive for polyurethane
• Spirit level and tape measure for marking
• Surface degreaser
• Painter's tape for temporary fixation
• Sandpaper grit 180–240 for sanding before painting
• Acrylic primer
• Finish enamel

Installation technology according to manufacturer's recommendations

The manufacturer insists on a specific protocol for working with mounting adhesive. This protocol is fundamentally different from installing ordinary liquid nails and cannot be simplified without loss of bonding quality.

• Apply adhesive to the back side of NPU-436.1L
• Place the product against the surface and press briefly
• Remove from the surface — this is a mandatory step
• Hold for 3–5 minutes in an open state, without pressing against the wall
• Press firmly against the surface and hold for 5–10 seconds
• If necessary, secure with painter's tape during full curing

Open time — critically important. At this moment, the solvent from the adhesive partially evaporates, the polymer base activates and gains initial adhesion to air. Without this stage, the adhesive will not provide reliable bonding, especially on smooth primed surfaces.

Final preparation for painting

1. Dust removal — after installation and adhesive curing, remove dust from the product surface
2. Priming — apply acrylic primer in an even layer
3. Matting — after the primer is completely dry, light sanding for better adhesion
4. Finish coating — varnish or enamel in 2 coats with intercoat drying

In the Prestige version, the product comes with factory hand sanding — the matting step can be skipped and you can proceed directly to applying the finish enamel.
