Installation Guidelines

Warning: Consult the Technical Data Sheets and SDS before using.

Installation Instructions: For detailed installation instructions refer to the DE NEEF® technical bulletin for your application.

Due to its fast setting characteristics, it is designed to be pumped or sprayed in place using conventional, plural spray/pour equipment fitted with a static mixer.

Heated pumping equipment is not recommended for this product. If heated pumps must be used, the set temperature should be no greater than 85°F

Injection: During injection the grout will follow the path of least resistance. When the material has stopped penetrating it will continue to expand against the limits of the confined space and compress within itself, forming a dense, closed cell foam.

Extreme conditions: For application procedures in extreme temperatures and specific environments or equipment recommendations call the DE NEEF® Technical Service Department.

Cleaning: Clean all tools and equipment which have been in contact with the resin with DE NEEF® Washing Agent before resin has cured. Products should be disposed of according to local, state, and federal laws.


Do not apply in temperatures less than 40°F or greater than 95°F. (Material cures slower at cooler temperatures and working time will be substantially reduced at higher temperatures).
