CERESIT CT 84 EXPRESS PLUS

Features and Benefits

Application from -10°C and at high humidity – especially recommended for work in low temperature when cement adhesives drying time is significantly longer.

Properties

Yield: 10 m² – 100% more than traditional cement adhesives; 15% higher adhesive strenght than traditional cement adhesives

Anchoring after ca. 2 h – speeding up thermal insulation work. In case of application of CT 84 and Ceresit Ceretherm Express system insulation work can take even 5 days less

Perfect for ”warming to warming” system – 1 m² of expanded polystyrene boards fixed with CT 84 adhesive weight 100 g, instead of 5 kg in case of cement adhesives

Enhanced thermal insulation properties – CT 84, unlike traditional cement adhesives, has thermal insulation properties similar to foamed polystyrene or wool

High homogeneity of adhesive thanks to metal ball protecting against too large air bubbles

Ceresit CT 84 polyurethane adhesive is used for fixing expanded polystyrene boards in the complex Ceresit Ceretherm systems for thermal insulation for external building walls (ETICS). Approximately 2 hours after the application, the foamed polystyrene boards may be smoothed, anchored and, then the armoured layer may be applied using the Ceresit CT 85, CT 87. CT 84 polyurethane adhesive is also used for fixing such materials as EPS and XPS foamed polystyrene for such surfaces as wood, OSB boards, glass, bitumens, ceramic bricks, concrete, coated and galvanised sheet plate, dry cellular concrete and after water impact, drywall, and for layered fixing of expanded polystyrene boards under conditions of normal and lower temperatures, also in thermal systems.

Step By Step

Preparation of the PU-adhesive

 

Shake the container energetically for several seconds, remove the valve cup and screw the gun on the container held with the valve upwards. Caution! The gun valve should be twisted off. After screwing the container on, the valve gun may be opened and adhesive may be released with pressing the trigger. Prior to fixing EPS, fix the start strips. CT 84 should be applied with the gun held with the container upwards, with the distance between the gun and the board maintained to enable correct application of adhesive

Application of the PU-adhesive

 

In case of fixing insulation panels in  the CT 84 additonal thermal insulation system, application should be done on the perimeter of the board, at the distance of about 2 cm  from the edge, and in one strip across the centre of the board, parallel to its longer sides. When gluing insulation  panels for foundation thermal insulation, apply CT 84 in 5 vertical strips parallel to the shorter sides of the board, in the distance of about 2 cm from the edge.

Fixing the insulation boards

 

Immediately press the board to the wall and hold it with small pressure with a long float. Smoothness of the surface of the EPS boards may be adjusted within 20 minutes of their fixing, with the use of a long float.
