Description
The W6 is a 6 mm wet plaster profile made by Dombud: a 2.5 m steel guide strip set into the plaster mortar, so the float runs along a straight, fixed line instead of the plasterer's eye. The same strip comes 10 mm high as the 10 mm W10 strip, and both sit in the full rendering range at Renders World.
How a Wet Plaster Profile Works
Dombud sells the W6 as a listwa podtynkowa, an under-plaster strip. It is an auxiliary part of the plastering job rather than a finish: set into the plaster mortar, it guides the coat so it goes on evenly, and it stays inside the coat once the wall is finished. The maker lists what the strip is for:
- guiding the plaster coat precisely and evenly on walls and ceilings;
- a flatter surface that leaves less to sand afterwards;
- gypsum and cement-lime plasters and other finishing systems;
- plaster applied by hand or by machine, in housing, commercial and industrial work.

6 mm or 10 mm
The W6 and the W10 are one strip in two heights, and the figure in the name is the height of the profile. Because the strip stays inside the coat, the height is chosen with the plaster thickness in mind:
| Strip | W6 | W10 |
|---|---|---|
| Height | 6 mm | 10 mm |
| Suits | the thinner coat | the thicker coat |
| Length at Renders World | 2.5 m | 2.5 m |
Dombud also makes the W-6 in a 3 m length. The shop sells the 2.5 m length, and a 3 seen beside the W6 name is that length, not a height: this wet plaster profile is 6 mm high.
Material
The descriptions of the material do not agree. The difference is worth knowing before an order:
- the listing gives steel, and the product photo shows a perforated metal strip;
- Dombud's own page for the W-6 names no material, only resistance to corrosion and to deformation;
- Dombud's page for the 10 mm W-10 describes the material as a durable plastic.
If the material decides whether the strip suits your job, call Renders World before ordering and ask what is on the shelf. Neither the listing nor Dombud's page states a galvanised or any other coating, and neither publishes a technical sheet or a declaration for the strip.
Corners in the Same Plaster
A wet plaster profile sets the face of the coat across a wall; it does not protect an external corner. For corners in wet plaster, Renders World stocks an aluminium wet plaster corner bead in 3 m lengths.
Questions Buyers Ask
Is the W6 a 3 mm strip?
No. W6 is 6 mm high, both on the listing's specification and in Dombud's range. The 3 in the Dombud range is a 3 m length, which the shop does not sell.
Which plasters is it for?
Gypsum and cement-lime plasters and other finishing systems, applied by hand or by machine, on walls and ceilings.
Can it be used outside?
Dombud's page describes plastering systems on walls and ceilings and does not address exterior use. Ask the shop before planning it into an external wall.
How is it sold?
By the single 2.5 m length. A run longer than 2.5 m takes a second strip.
