Ampatex Ombrello
New
Weather protection / construction period cover, fully self-adhesive
Transparent, full-surface adhesive vapour check and weather protection membrane.
- Transparent: furring, chalklines, penetrations, etc. remain visible
- Adhesive made of UV acrylate: penetrating water does not affect the adhesive
- Natural weathering period of 3 months: sufficient time for construction phase
- Sturdy and anti-skid properties: enables safe inspections during the construction phase
Transparent, full-surface adhesive vapour check and weather protection membrane. Used, for example, to temporarily cover wooden ceilings during the construction phase or to ensure airtightness on wooden materials and other substrates.

Before installation, ensure that the substrate is clean, dry and free of dust, ice and grease. Align Ampatex Ombrello with the markings, imprint or chalk line. Overlap Ampatex Ombrello by at least 10 cm. Note the dashed overlap line for this.
- Roll out the membrane so far that it can be aligned.
- Then wind the roll up again to about 50 cm before the starting point.
- Peel off the wide cover strip and fold it under the roll.
- Roll the roll over it and stick on the beginning of the membrane. Now the loose end of the cover strip sticks out from under the roll.
- Pull evenly on the wide cover strip to unroll the roll. While rolling, rub the membrane well on the surface with a broom or similar.
Important: Ensure adequate drainage when applying on horizontal or flat components.
For panel joints and connections, use Ampacoll Flexx pro 150 mm. Penetrations are best sealed with Ampacoll BK 535 (50, 80 or 120 mm). Substrates may have to be pre-treated with Ampacoll Primax or Ampacoll Airmax.
Plan/ensure appropriate drainage. Heavy precipitation must be able to drain off in a controlled manner to avoid standing water.
