Ceresit Polyurethane Adhesive CT 84 Express XPS

Ceresit CT 84 Express XPS is a high-quality polyurethane adhesive designed for bonding XPS insulation boards. Thanks to its low-expansion formula, improved thermal insulation properties and high homogeneity, it delivers excellent performance during both assembly and bonding. This foam is ideal not only for applying insulation materials, but can also be used as an assembly adhesive for a wide range of other applications. With a yield of up to 14m² per 750ml, Ceresit CT 84 Express XPS is an effective choice that saves you time and money – that's 100% more than traditional cement adhesives. With 15% more adhesive strength than conventional cement adhesives, you can be sure of a strong and reliable bond. The adhesive also creates a firm anchor in just 2 hours, which shortens the time needed to complete the job. Ceresit CT 84 Express XPS is the ideal choice for fast, effective and durable bonding of insulation materials.

How to use:
1. Shake the can vigorously for a few seconds, remove the valve cap and screw the gun onto the can, holding it with the valve facing up. The gun valve should be unscrewed; once the can is screwed on, you can open the valve gun and release the adhesive by pulling the trigger. Before attaching the EPS, fix the starter strips in place.

2. When attaching insulation panels in an additive thermal insulation system, CT 84 should be applied around the perimeter of the board, about 2cm from the edge, and in one strip across the centre of the board, parallel to its longer sides. When bonding insulation panels for foundation thermal insulation, apply CT 84 in 5 vertical strips parallel to the shorter sides of the board, approximately 2cm from the edge. 

3. Immediately press the board against the wall and hold it with light pressure using a long float. You can adjust the smoothness of the EPS board surface for up to 20 minutes after fixing them in place using a long trowel.
