Installation

Surface Preparation and Use
Use gloves, wear eye protection, and avoid skin contact. The concrete joint must be completely dry and dust-free. All joints should be cleaned to their full depth of 2” minimum. For best results recut joints with a dry diamond blade. Open surface texture or bare concrete is recommended for all joint facings. In filling floor cracks, the cracks should be routed out and cleaned before filling. Mask areas which must be kept free of polyurea.

Mixing Instructions
All materials should be at or above 45°F. Premix each part separately before combining the two ingredients at the following volume ratio: one part Boncrete™ Polyurea Joint Filler 70 Part A to one part Boncrete™ Polyurea Joint Filler 70 Part B. Due to the extremely short pot life, it is strongly recommended that either the dual component cartridges be used, or dual-component metering-and-mixing equipment be used to mix and apply the material.

Installation:
Boncrete™ Polyurea Joint Filler 70 should be installed full-depth in the joint or crack.

Temperature Dependency
Temperature will affect the working properties of the material. Do not use at a temperature below 0°F.
