About this product
The water-based, nonflammable version of Weldwood contact cement. It has the longest open time of the three contact adhesives in this release, up to 3 hours, against about 2 hours for the spray and gel.
Using this specific product
DAP Weldwood Nonflammable Contact Cement is listed here as the Brush or roll-on version for laminate, veneer, and contact cement. For bonding parts, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Brush or roll-on; related versions can use different timing.
- For laminate, veneer, and contact cement, pay particular attention to surface fit, cleanliness, clamping pressure and bond-line thickness.
- The source gives no conditions for this time.
How to check readiness
Test a noncritical offcut or wait for the stated load milestone before stressing the joint. The data sheet gives an open time of 2.5 to 3.0 hours. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. The data sheet says to wait at least 72 hours before exposing bonded assemblies to direct sunlight or temperatures above 150°F.
Avoid this mistake
Handling strength and full load strength are different milestones.
