Professional installation technology of the maximum profile

Surface preparation before installing crown A100 requires maximum attention due to the significant weight of the product — 1.2 kilograms per two-meter plank. The installation zone is cleaned of any contaminants using professional cleaning agents. Loose plaster areas are removed down to a solid base using a 200 mm wide trowel. Depressions deeper than 8 mm are filled with reinforcing gypsum putty containing fiberglass and leveled to the main plane using a metal trowel.

The prepared base is treated with a professional deep-penetration primer such as Ceresit ST17 or Knauf Grundirmittel in two layers with an intermediate drying time of 3 hours to maximize surface layer strength and improve adhesion by 3-4 times. The primer consumption is 200-250 grams per square meter to achieve maximum strength of the base under a heavy cornice.

The installation line is marked using a professional rotary laser level to ensure the heavy 100-millimeter-high profile is strictly horizontal. From the ceiling, a distance of 100 millimeters minus the compensatory gap of 8-12 millimeters is measured to accommodate a powerful LED strip for creating an impressive concealed lighting effect.

The mounting adhesive of a reinforced professional formula such as Moment Montage Extra Strong Plus, Titan Professional, or Makroflex Ultra is applied in a continuous wide strip of 12-15 millimeters across the entire height of 100 millimeters and width of 53 millimeters on the back of the heavy cornice. Due to its significant weight, the maximum amount of adhesive is required to ensure secure fixation over the entire contact area.

Additional mechanical fixation using professional self-tapping screws of 70-80 millimeters length is mandatory for heavy cornices in rooms with very high ceilings. Stainless steel screws are screwed into the cornice into a strong base at intervals of 300-400 millimeters. Screw heads are recessed by 2-3 millimeters and masked with professional acrylic putty followed by sanding.
