• Package contents: One beige 9.5 oz SEM 29482 cartridge. Dispensing gun, any spray applicator, nozzles, brushes and preparation supplies are separate unless confirmed in the stocked package. This is one retail cartridge, not a 12-cartridge case.
• Material-led selection: Properly prepared primed/painted surfaces, aluminum, steel, fiberglass, SMC, glass, concrete, wood and plastics under substrate-specific preparation. Treated wood can interfere; verify the exact material.
• Preparation and application: Follow the current 2-IN-1 TDS preparation for the actual substrate; the method differs for metal, coatings, composites and other materials. Do not use directly over acid-based self-etching primers or vice versa.

Review one 9.5 oz cartridge and the confirmed configuration before ordering. Check the shipping options and delivery estimate shown for your destination at checkout.

Bring the metal/substrate to 70°F / 21°C for one hour before application under the exact TDS. Follow the current 2-IN-1 TDS preparation for the actual substrate; the method differs for metal, coatings, composites and other materials. For beading, use the approved manual or pneumatic setup and prime by hand before pneumatic dispensing. Spray application requires a separate approved sprayable-seam-sealer applicator and the prescribed air/nozzle setup; an ordinary caulking gun alone does not provide the spray pattern. Do not apply directly over acid-based self-etching primers or apply those primers directly over this sealer; SEM warns of cracking or blistering. At 70°F / 21°C: working time 20–40 minutes; set time 1 hour; solvent-based paint window 0–24 hours; waterborne paint after 1 hour. Cure reference: 4 mm per 24 hours at 50% relative humidity. Actual conditions and bead thickness affect results. Tool or finish the seam under the exact instructions and verify continuity before the following coating. Follow the actual label/SDS. Inspect the delivered parts before starting the work.
