Uses
High quality fiber-reinforced, polymer modified, cementitious adhesive in a gray shade, specially designed for the strong bonding of expanded polystyrene (EPS) boards. It exhibits excellent adhesion to substrates such as concrete, plaster, bricks, cement blocks and aerated concrete. Reinforced with suitable fiberglass mesh, is also used for the coating of thermal insulation boards, on external and internal surfaces of buildings.
Advantages
• Strong adhesion to the substrate such as concrete, cement, stone, masonry
• High performance
• High mechanical strength
• Excellent workability.
• Easy to handle and apply
• Durability over time.
• High resistance to changes in temperature between heat and cold
• User and environmentally friendly
SUBSTRATE PREPARATION
Before application, make sure the substrate is stable and clean, free from dust, oils, loose materials or old paints
APPLICATION
Mix the content of a 25 kg bag, with 5.5 – 6 lt of water, using a low-rev electric mixer until a homogeneous, lump-free mixture is obtained. Leave the mixture to set for five to ten minutes and stir again.
Use as adhesive: For smooth substrates: The adhesive is evenly spread and combed over the entire surface using a notched trowel at a thickness of 2 – 3 mm. For uneven substrates: The adhesive is applied in stripes around the edges of the board and in 3 – 4 selected dabs in the center using a notched trowel. The adhesive must cover the 40% of the boards surface. Place and press the insulation boards starting from the bottom of the masonry crossways without gaps.
As a reinforced coating: When used as a fiberglass reinforced coating, apply the mix all overthe surface of the insulation
board to a thickness of 2 – 3 mm. Place the appropriate MARMOLINE fibreglass mesh to the prepared surface and press with a spatula or trowel until the mesh is fully embedded in the adhesive. The strips of the mesh should overlap by 10 cm approx. Finally, smooth the surface, while simultaneously removing excess mortar. Suitable anchors should also be used to secure the installation of the insulation boards. You can use the mixture within 2-4 hours, depending on the environmental conditions (temperature etc.)
TOOLS CLEANING
With plenty of water immediately after use. Hardened and/or cured material can only be removed mechanically.
