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 404 Part A to one part 404 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
Boncrete™ 404 is available in quarts, gallons, and 5 gallon pails,
and 300ml & 150ml cartridges. Shelf life is approx-imately one year
if kept in unopened cans in a dry area at 75°F.
