adhesive mortar for gluing foamed polystyrene boards





FAST NORMAL S thanks to its properties, it is perfect for gluing foamed polystyrene panels (including panels with the addition of graphite) on various types of surfaces inside and outside the building such as concrete, hollow bricks, bricks, cement plaster, cement and lime plaster, etc.


FAST NORMAL S is an adhesive mortar is a form of dry mineral mixture, modified with synthetic polymers, frost and waterproof with increased flexibility.


25 kg bag




Surface preparation


Surfaces should be strong and free from any type of dirt that reduces mortar adhesion (e.g. residues of old, loose-fitting paints, all kinds of lichen, dust and dirt). Larger unevenness should be levelled with plastering mortar or levelling mortar. Dusty surfaces should be reinforced with FAST GRUNT G. Walls made of highly absorbent materials should be primed with FAST GRUNT U.




Preparation and use

Mix  the contents of the package to about 5.5 liters of water and mix with a slow-running drill until c mass onsistentis obtained. Leave for about 10 minutes and mix again before use (do not add water). The mortar prepared in this way is suitable for use for  2.5 to 3 hours. During the works it is necessary to mix the mortar regularly every 30 minutes.

Bonding polystyrene boards can be carried out in two ways. In case of insulation of even, plastered surfaces, the adhesive mass is applied to thin layer panels with a toothed trowel with square teeth of 8-10 mm, and then glued to the insulated wall. In the case of unplastered wall, mortar should be applied to foamed polystyrene boards using the "peripheral-point" method, i.e. using a trowel along the perimeter of the foamed polystyrene board with a band of about 3-4cm wide and additional 3-8 pieces. The size of pieces should depend on the number of them. The adhesive mortar should cover not less than 40% of the board surface. Correctly made rims should be sufficiently far from the edge so that after pressing the board the glue does not go beyond its outline.

Styrofoam boards should be glued tightly one next to the other, starting from the skirting board up to the roof with the preservation of the passing system of vertical joints. If it is necessary to apply additional protection of the system with the use of mechanical fasteners, their assembly may start not earlier than after 3 days from gluing the foamed polystyrene panels. The exact number, type and method of application should always be based on the project of insulation. During the works it is absolutely necessary to observe appropriate atmospheric conditions, i.e. to avoid too much sunlight and high humidity.

Important additional information in the case of gluing polystyrene foam with the addition of graphite:

- Do not install heated foamed polystyrene,

- Do not allow the panels to heat up during gluing and in the initial period of bonding,

- it is absolutely necessary to use shields on the scaffolding that limit the access to sunlight,

- Non-compliance with the above requirements may result in the release of the glued polystyrene foam.
