Workshop Best Practices

Ventilation

Always work in a well-ventilated area. Use a respirator rated for organic vapors when using solvent-based cements.
Even Application

Apply a thin, even coat to both surfaces. If it clumps, you have applied too much. Use a stiff brush or notched spreader.
The Tack Test

Touch the adhesive with a clean piece of paper or glove. It should feel tacky but not transfer to the paper. If it doesn't stick, it's too dry.

Note: This tool provides estimates based on general adhesive physics. Always test on scrap foam pieces before beginning your final project.
