Installation

General Instructions
(If using cartridges, additional usage directions are available. See our information sheet labeled "Cartridge use directions".) See separate doweling, laminating, and patching instructions for more specific instructions. CSI format specifications are available.

Surface Preparation and Use
Use gloves, wear eye protection, and avoid skin contact. When grinding cured joints, wear a dust mask. Substrate to be bonded must be completely dry and dust- free. Mix only the amount of epoxy which can be used in 10 minutes. Avoid stressing joint before complete cure of epoxy. Mask areas which must be kept free of epoxy. Clean uncured epoxy from tools with toluene or xylene. Remove cured epoxy mechanically.

Mixing Instructions
All materials should be at or above 55°F. Combine the two ingredients at the following volume ratio: two parts 404NS Part A to one part 404NS Part B. Mix thoroughly--- ingredients must be blended homogeneously for proper cure.

Temperature Dependency
Temperature will affect the working properties of the material. Approximately every 15°F results in doubling the speed of cure. Therefore, at 90°F set time is cut in half, at 60°F the set time is doubled. Do not use on a substrate at a temperature below 55°F.

Coverage
Approximately 30 square feet per gallon when applied at 50 mils (1/16th of an inch). 231 cubic inches per gallon.

Availability

Packaging and Storage
Bonstone™ 404 NS is available in quarts, gallons, and 5 gallon pails, and 300ml and 150ml cartridges. Shelf life is approximately one year if kept in unopened cans in a dry area at 75°F.

**If BONSTONE™ 404NS Part A is exposed to below room temperature conditions for extended periods of time, it may crystallize, giving it a stiff, grainy consistency. The product must be reconstituted before use by heating it to 150°F degrees. Stir until it becomes a homogeneous liquid.
