Installation of Wall Mural in Fiberglass

To install the Wall Mural in a humid environment and ensure a lasting and flawless result, it is essential to follow a meticulous process that includes specific preparation and protection steps. Here are the detailed phases:

Phase 1: Wall Preparation and Restoration (The Secret to a Perfect Base)

This is the most critical phase, especially in environments subject to humidity. The goal is to create a surface as smooth, uniform, and sanitized as possible to prevent mold formation.

• Thorough Assessment and Cleaning: Remove any traces of mold, fungi, or dirt from the wall. If present, clean carefully with specific anti-mold products.
• Smoothing and Filling (If Necessary): If the wall is damaged, flaking, or if it is a previously tiled wall, you will need to intervene to make it smooth. Remove any residues of old adhesives or Wall Murals.
  • For uneven walls, proceed with smoothing to even out the surface.
  • In the case of tiles, fill the joints and the entire area to create a continuous surface free of unevenness. The goal is to achieve a wall as white and smooth as possible.

Phase 2: Application of the Anti-Condensation Primer (PRIMER TA)

Once the wall is prepared, clean, and smooth, it is time to apply PRIMER TA, the water-based acrylic primer with glass microspheres.

• Function: PRIMER TA is designed to create a thermal barrier on the wall, helping to prevent condensation formation and consequently the reappearance of mold and fungi. It also improves glue adhesion and helps make the surface more uniform and white.
• Application: Apply an even layer of PRIMER TA (using a roller or brush) over the entire surface that will receive the Wall Mural.
• Drying: Allow the primer to dry completely according to the instructions before proceeding.

Phase 3: Preparation of the Adhesive

While the primer dries, you can start preparing the Wall Mural and the adhesive.

• Adhesive Preparation: Use the specific high-quality adhesive for fiberglass Wall Mural, carefully following the instructions for proportions and mixing times.
• Marking for alignment of strips: Use a plumb line and mark reference points on the wall; this will allow you to adjust the positioning of the sheet so that it is perfectly perpendicular to the floor during installation.

Phase 4: Installation of the Wall Mural

Begin the actual installation after the primer has completely dried.

• Adhesive Application: Apply the adhesive evenly on the back of the first Wall Mural sheet (or directly on the wall).
• Sheet Application: Position the first sheet starting from the top, aligning it precisely. Use a spatula or a special roller to remove any air bubbles, working from the center towards the edges.
• Alignment: Apply the subsequent sheets, ensuring that the patterns align perfectly and that the edges are closely butted without overlaps or gaps.
• Finishing: Once all sheets are positioned, cut the excess Wall Mural along the ceiling, baseboard, and corners with a cutter, using a ruler for precise cuts. If bubbles are present, lightly pierce the surface to allow the air to escape completely and press the raised areas to ensure the Wall Mural adheres fully to the substrate.

Phase 5: Application of the Two-Component Resin

This is the crucial step for durability in humid environments and sealing the fiberglass fibers present on the Wall Mural.

• Mixing the Two-Component Resin: Follow the mixing ratio indicated on the product packaging. It is essential to respect the precise proportions to ensure proper polymerization and optimal resin performance. Make sure the mixture is homogeneous, as free as possible from air bubbles and streaks.
• Resin Application Tools: You can use a short-pile roller or a brush, depending on the surface and your preference. Apply over the entire Wall Mural and work in sections to coat every part.
• Sealing the joints: Pay particular attention to the joints between sheets, ensuring the resin penetrates well to create a protective barrier against frequent washing and humidity.

Phase 6: Perimeter Sealing with VICEVERSA DIAMOND (Final Protection)

This is the crucial step for durability in humid environments.

• Function: VICEVERSA DIAMOND is a silane polymer-based sealant/adhesive, essential for creating a protective barrier on the edges of the Wall Mural. It prevents moisture and water from infiltrating under the mural, preventing detachment, lifting, and mold formation.
• Application: Once the Wall Mural has been installed and the adhesive has set (usually after a few hours, following the adhesive instructions), apply a thin bead of VICEVERSA DIAMOND along all the perimeter edges of the mural: top, bottom, and sides where the mural ends. You can use a spatula or a moistened finger to spread the sealant evenly and discreetly.
• Setting Time: The sealant has an immediate initial set, but the final cure is reached in 12-18 hours.
