Use and Care Manual

2
• APPLICATION: Stir cement thoroughly. Using a brush, short nap roller or notched spreader, apply one
uniform coat of cement to each surface to be bonded, working cement in one direction only.
• Let coated surfaces dry for 15 minutes. Dry time may vary with temperature, humidity and thickness of
coat applied. Properly coated surfaces feel tacky and appear glossy when dry. Test for dryness by pressing
kraft paper against adhesive surface. When dry, adhesive should bond slightly to, but not transfer to, the
kraft paper. Recoat any dull spots after first coat is dry. Two coats may be required on rough or porous
surfaces.
• ASSEMBLY: Surfaces may be assembled up to 2 hours after cement is applied. If the cement is allowed to
dry more than 2 hours, reactivate it by applying another coat of cement and drying normally.
• Align surfaces into exact position and press together, moving from one end to the other to avoid bubbles.
Cement joins on contact, surfaces cannot be shifted. For large areas, use dowels to prevent surface contact
while positioning surfaces. Place dowels every 6 to 12 inches. Remove dowels as surfaces are pressed
together.
• Apply firm pressure to the entire area using a J-Roller (not over 3 inches wide) or a wood block and
hammer. Insufficient pressure may allow blisters or bubbles to form later. Work from the center to the
edges to avoid bubbles. Apply extra pressure to edges.
• Trimming or finishing operations can be performed immediately after bonding. Let adhesive assemblies
cure for at least 72 hours before exposure to direct sunlight or temperatures over 150°F.
• Should not be used for structural applications, or for bonding copper, copper alloys or Styrofoam. The
solvents in this cement may stain or damage painted surfaces, vinyls and some plastics. Test a small area
first before actual use. Not recommended for heavy gauge metal.
