Working Surfaces

Surface must be clean and dry of any material that may deter adhesion. Sand nonporous surfaces. Store adhesive at 60°F. or higher for 24-48 hours before use. Cut and fit all materials before applying adhesive. Apply a liberal coat of adhesive to both surfaces. Allow adhesive to dry before bonding surfaces. Position surfaces carefully before assembly because bonding is immediate upon contact. If surfaces do not bond immediately, the adhesive has been allowed to dry too long or not enough cement was used. In either case, repeat application. After assembly, roll entire bonding surface with a 3" wide roller. Trim and finish can be started immediately after bonding.

Cleanup

Use warm, soapy water to clean tools and excess adhesive while wet. Remove dried adhesive with mineral spirits. Follow solvent vendor’s precautions when using solvents. NOTE: Test solvent in an out-of-the-way area to make sure it will not mar or attack the surface.

Directions for Use:

1. Surfaces to be bonded must be clean and dry. Sand non-porous surfaces. Stir adhesive until uniform in color.
2. Pre-fit all parts then apply adhesive to both surfaces using a brush, paint roller or spray equipment. USE ENOUGH CEMENT. If brushing or rolling, apply 100% coverage (3.0 dry grams or 2.09 wet mils per sq. ft. or higher). If spraying, coating weight of 2.5–3.5 dry grams should be applied. The atomization at the gun should be 5–20 psi and the fluid pressure should be 10–15 psi.
3. When applying contact adhesive to porous material such as plywood and edges, it is advisable to apply two coats. Apply the first coat and allow it to dry; this will act as a sealer. When dry, apply the second coat and allow it to dry properly before bonding. This helps to insure that the adhesive does not soak-in below board fiber and that you have the proper amount on the surface to achieve a strong, permanent bond.
4. Let adhesive dry completely. Water-based contact cement will change color when dry. To check, use the back of your fingers to press into the adhesive and lift up. Any adhesive transfer indicates that the adhesive requires more time to dry. If the adhesive feels tacky, but there is no transfer, the adhesive is ready for bonding. If there are heavy areas of adhesive present, press the back of your fingers in the adhesive and twist. If a skin has formed, this will tear it open and allow you to notice that the adhesive needs more dry time. DO NOT use the palm of your hand to check for dryness. Dry time can vary depending on temperature, humidity and coat weight. Drying time can be reduced using air movement and drying ovens.
5. Bonds can be made as soon as the adhesive is dry. Bonds made anytime in the 2 hour open time will be as strong as those made immediately after dry.
6. Position the surfaces carefully before assembly because bonding is immediate upon contact. It is sometimes advisable to place a piece of kraft paper or several wood dowels over the lower bonding surface, position the other surface on top and carefully slide the paper or dowels out as contact is made. If surfaces do not grab immediately, the adhesive has been allowed to dry too long or not enough cement was used. In either case, repeat application.
7. Use good uniform pressure to insure good film fusion. A pinch roller is the optimum method for applying pressure. Use the maximum possible pressure without damaging the substrates. Minimum recommended pressure is applied with a 3” wide “J” roller.
8. Assembled pieces can be machined immediately after bonding.
