DAP Weldwood Original Contact Cement
Before ordering, please read the "Product Description & Specs" tab content for more information about this item.
DAP Weldwood Original Contact Cement is a multi-purpose neoprene rubber adhesive that forms instant, high-strength bonds on a variety of surfaces. Offers hundreds of uses for the home, office, and workshop. Forms strong bonds on contact to eliminate the need for clamps, temporary fasteners, and long set times.
Features & Benefits
- Permanent bond
- High heat resistant
- Water resistant
- Interior & exterior use
- Creates a strong durable bond
Uses & Applications
- Plastic laminate for counters and tabletops
- Wood and plastic veneers
- Paper and cardboard
- Some plastics and vinyls
- Other porous and nonporous materials
Made in the U.S.
- Stir Contact Cement thoroughly with a standard paint paddle or stirring stick.
- Pre-fit all parts before applying Contact Cement.
- Both surfaces must be clean, dry and free of foreign material. Painted or non-porous surfaces must be roughened before adhesive is applied.
- The temperature of air, adhesive and surfaces should be above 65°F (18°C) for a minimum of 24
hours before and after application to ensure proper drying and bond strength.
- Using a paint brush, short nap roller or finishing trowel, apply an even coat of adhesive to both surfaces.
- Allow both surfaces to dry 15 to 20 minutes (dependent on temperature and humidity). Dry Contact Cement will feel tacky and appear glossy.
- Align surfaces into exact position and press together, moving from one end to the other to avoid bubbles.
- Once surfaces are joined, a minimum of 25 lbs. per square inch of pressure should be evenly applied to surface starting in center and working out to edges.
- No clamping required. Contact Cement bonds permanently when sufficient pressure is applied and reaches maximum holding strength in 7 days
- Trimming or finishing operations may be performed immediately after bonding. Allow at least 72 hours of curing before exposing bonded assemblies to direct sunlight or temperatures over 150°F (66°C).

Question & Answers
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
