Michno System Point Profile Installation Guide
The Michno System is a set of brackets (point profiles) that allow for the attachment of cladding boards (e.g., gypsum plasterboard or OSB) to walls, ceilings, and floors without constructing a traditional frame. Below is a step-by-step installation guide.
Mark the installation points. Mark on the surface (wall, ceiling, or floor) the points where you will install the Michno System point profiles. Distribute them evenly (at 40 cm intervals, in a grid pattern). Mark the first point 10 cm from the corner of the surface to ensure the edges of the mounted board are supported. Use a measuring tape and level to mark the points.
Drill the holes. At the marked locations, drill holes into the substrate using a drill. Each hole should be approximately 3.2 cm (32 mm) deep, and the drill bit diameter must match the expansion plug (e.g., for a 6 mm plug, use a 6 mm drill bit). After drilling, remove dust from the holes (e.g., by blowing or vacuuming).
Insert plugs and screw in profiles. Place expansion plugs (metal sleeves that expand in the wall) into the prepared holes. If the substrate is wooden, skip the plugs—you can screw the profiles directly into the wood. Then screw the Michno System point profiles (round mounting brackets) into the holes. Use a screwdriver or drill, selecting the appropriate bit for the profile head. Screw each profile so that its round base (disc) remains a few millimeters above the surface—do not tighten it completely, leaving some play for height adjustment.
Level the profiles. Adjust all installed profiles to be in the same plane—they must protrude the same distance from the surface. On a wall, this means they form a perfectly vertical plane; on a ceiling—a horizontal plane; and on a floor—the same height above the floor. Place a long straight batten (straightedge) against the protruding discs of the profiles or use a level to check if any profile sticks out more than the others. Adjust the height of each profile by screwing it in deeper or unscrewing it slightly until all are at the same level. If installing profiles on the floor, remember to use the Power King expansion sleeve. This high-quality mounting element is made of plastic, specifically designed for metric pins. Inside the sleeve is a counter that automatically sets and locks the pin's position relative to the substrate during expansion. The integrated claw washer prevents the sleeve from rotating in the hole, increasing the safety and durability of the mounting.
Screw in the cladding boards. Attach the cladding boards (e.g., gypsum plasterboard or OSB) to the leveled profiles. Start by positioning the first board on the wall or ceiling so that its back side rests against the protruding discs of the profiles. Then screw this board to the profiles using screws (use the appropriate type of screws for the board material, e.g., for plasterboard or wood). Before screwing the board, mark on its surface the points corresponding to the positions of the profiles—you can measure these points with a tape measure (every 40 cm from the edge of the board) or place a straight batten against the installed profiles and draw lines on the board indicating these points. This will help you hit each profile easily when screwing. Install the remaining boards in the same way until the entire surface is covered. When installing on the floor, proceed similarly. Simply lay the board (e.g., OSB) on the profiles and screw it from above precisely where the profiles are located underneath.
CD Hanger (WK8T) Installation – Step-by-Step Guide
CD Hangers (WK8T) are special brackets that allow for the secure attachment of metal CD60 profiles to wall or ceiling structures in drywall systems.
Such a hanger enables the mounting of a metal CD profile to the wall or ceiling surface in a drywall system. Thanks to the click-type snap connection, the profile can be easily seated in the hanger, and the special rubber (elastomer) insert inside provides a flexible, sound-absorbing connection (vibration reduction).
Preparation – Tools and Materials
Before starting work, prepare the following tools and materials:
WK8T Hangers – the quantity should ensure hanger spacing every 40 cm (each hanger includes a long wood screw and a metal expansion plug for concrete or brick).
CD 60 Profile – a metal load-bearing profile to be mounted on hangers (on the ceiling/wall, main profiles are spaced every 40 cm).
Drill (preferably with a hammer function for concrete) and a drill bit matching the diameter of the expansion plug (typically 6–8 mm depending on the plug).
Screwdriver or – more conveniently – a power screwdriver (electronic drill-driver) with bits matching the hanger screw head.
Pencil or marker and a measuring tape / folding ruler for marking installation points.
Level and optionally a chalk line (chalk string) – for marking straight lines and later checking the level of the profiles.
(Note: In the steps described below, we assume the ceiling is concrete and the wall is brick. If mounting the hanger to wooden elements – e.g., rafters, joists, or wooden studs – do not use a plug, but simply screw the screw directly into the wood after pre-drilling a pilot hole with a smaller drill bit.)
Installing the WK8T Hanger to the Ceiling
Follow these steps to attach the WK8T hanger to the ceiling and install the CD profile:
Mark the profile and hanger location: Mark a line on the ceiling along which the CD profile will run. Use a pencil and measuring tape for this (you can use a taut string or laser to ensure the line is straight and parallel to the walls). On the marked line, mark the points where you will install the hangers – every 40 cm along the planned profile (e.g., for a 3 m long profile, you will need 7-8 evenly spaced hangers).
Drill holes in the ceiling: Place one of the hangers against the ceiling so that the mounting hole of the hanger aligns with the marked point. Mark the drilling spot through this hole with a pencil. Then drill the ceiling at the marked spots using a drill. Note: If the ceiling is concrete, use a hammer drill and a concrete drill bit with a diameter matching the plug (e.g., 6 mm for a standard 6 × 32 mm plug). Drill perpendicularly into the ceiling to a depth slightly greater than the length of the plug. (For a wooden ceiling, you do not need a plug – just drill a pilot hole with a smaller drill bit for the screw.)
Insert the expansion plug: Insert the metal expansion plug into each drilled hole. Press it in so that it is flush with the ceiling surface (you can gently tap it with a hammer, but only lightly to avoid damage). The plug should fit snugly in the hole. (Skip this step for wooden structures – proceed directly to screwing in the screw.)
Screw the hanger to the ceiling: Position the base of the hanger (metal plate with a hole) against the ceiling so that the hanger hole aligns with the inserted plug. Insert the long screw provided with the hanger into the hole and turn it by hand to catch the thread in the plug. Then tighten the screw with a screwdriver or drill until the hanger is firmly attached to the ceiling.
