FL100 ST BASIC

Non-fiber-reinforced adhesive for thermal insulation boards

The FL100ST BASIC adhesive is used for bonding thermal insulation boards to substrates of brick wall, cellular concrete, exposed concrete, old plastered surfaces, etc. It ensures high bonding strength between the insulation boards and the substrate, as well as moisture resistance. It achieves high resistance to compression, bending, and 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.

Composition & Features

• Mixture of high specifications white cement, crushed marble of strictly selected granulometry and quality, 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.  C2E, W2. Granule size < 0.7 mm. Although the specifications and instructions presented in this bulletin have been prepared to the best of our skills, knowledge and experience, they should be taken as indicative results and require verification after many applications.  Users to whom this product is addressed should verify its suitability for the intended application.  The end user is responsible for any result of the use of the product.

Application

• 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 application. • The adhesive is applied to the surface of the insulating board either by covering the entire surface of the board with a serrated putty knife (8-10 mm), or by partially covering at least 40 % of the surface of the board (adding 3-4 drops around the perimeter in the center) with a mixture thickness of approximately 2 cm. • After a period of 2-3 days (at low temperatures a longer period is required) from the bonding of the thermal insulation boards, they should be fixed with special anchor bolts. • 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 be started 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. ATTENTION The FL100ST BASIC adhesive should not be used in the following situations:

  • Directly on plaster walls or plaster mortars, unless a layer of acrylic primer has been applied beforehand.

NOTES

  • For even better quality results, see the relevant MARMOPLUS product.
  • The FL100ST BASIC adhesive contains cement which is classified as an irritant. Consult the safety instructions and precautions listed in the Material Safety Data Sheet of the product.
Packaging & Storage

• 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.

Consumption

4-5 kg/m2 (1 cm thick/40% of the surface), depending on the type and quality of the masonry.
