FL100 ST THICK
Fiber-reinforced coarse-grained adhesive (White)
The FL 100 ST THICK adhesive is a cementitious mortar used mainly for smoothing the external surface of thermal insulation boards and for the installation of the fiberglass mesh sheet before applying the top coat plasters. It has the advantage that it can be applied in a large thickness (up to 2cm) and can essentially cover any imperfections created by the installation of thermal insulation boards. It ensures high bonding strength, resistance to moisture as well as environmental changes. It complies with: EAD 040083-00-0404, ETA 20/0778 – 20/0699 – 19/0472, in the context of MARMODOM’s BIOPANOPLY (EPS, XPS, WOOL) external thermal insulation systems, for the above uses. Homogeneous, ready-to-mix, industrial product of consistently high quality. It ensures good workability, increased application speed, it is economical and provides excellent results.
• Mixture of high specifications white cement, crushed marble of strictly selected granulometry and quality, polypropylene fibers, enriched with polymers and other special improving additives. • It complies with: EN 12004, EN 998-1 / EAD 040083-00-0404, ETA 20/0778 – 20/0699 – 19/0472. Granule size < 1.3 mm.
• The substrate must be clean, firm and free of any residues (loose particles of plaster or mortar, dust, grease, etc.) • The contents of the bag are gradually added to clean water (approximately 6.0 l/bag) under continuous stirring using an electric mixer at low speed until a homogeneous mixture is obtained. The mixture is allowed to cure for 5 minutes and then stirred again before the application. Bonding of insulation boards to masonry • The adhesive is applied to the surface of the insulation board either by covering the entire surface of the board with a serrated putty knife (up to 20 mm), or partially covering at least 40% of the surface of the board (peripherally adding 3-4 drops in the center) with a mixture thickness of approximately 20 mm. • After a period of 2-3 days (at low temperatures a longer period is required) from the bonding of the insulation boards, they should be fixed with the special anchor plugs. Installation of the fiberglass mesh • Next, a layer of adhesive up to 20 mm thick is applied to the outer side of the insulation board and while the adhesive is still damp, the fiberglass mesh sheet is placed on the surface and embedded using a smooth putty knife, so that it is eventually completely surrounded by the adhesive. • With the application of the desired finishing plasters, the thermal insulation system is completed. • When applying the insulation boards to the wall, the temperature should not be lower than +5 °C or higher than +35 °C. • During the application of the adhesive, and for a few hours afterwards, extreme climatic conditions (such as strong wind, rain, dust, direct sunlight, etc.) should be avoided. • All the above-mentioned thermal insulation works should start after the completion of internal plastering, the application of floor renders, etc. In particular, a waiting period of at least 3-5 weeks is required after the completion of these works. • Ready-to-mix cementitious adhesives should not be applied directly onto plaster walls or plaster mortars, except under the responsibility of the user and after an acrylic primer has been applied. The overdosage of water reduces the expected quality of the products. • For even better quality results, see the relevant MARMO PLUS product. • Ready-to-mix cementitious adhesives contain cement which is classified as an irritant. • Consult the safety instructions and precautions listed in the Material Safety Data Sheet of the product.
• In bags of 25 kg, on pallets. • In a dry place where frost does not form, for 12 months from the date of production, in unopened bags.
Approximately 12-15 kg/m2 for an application thickness of 1 cm depending on the substrate.
