Application tips & best practices
- Clean and dry bonding surfaces thoroughly — remove old adhesive, dirt, grease and contaminants.
- Roughen smooth surfaces lightly where recommended to improve mechanical adhesion.
- Cut the applicator tip to the preferred bead size and fit the cartridge into a standard caulking gun.
- Apply a continuous bead, avoid gaps; for vertical or overhead areas, rely on the non-sag formulation to hold in place.
- Allow the recommended cure time before driving (refer to manufacturer cure charts — cure time depends on temperature & humidity).
- Clean excess product immediately with recommended solvent before full cure.
Safety & handling
Always follow the manufacturer’s safety data sheet (SDS). General precautions include:
- Use gloves and eye protection (gloves included in package).
- Work in a well-ventilated area to avoid inhalation of fumes.
- Keep away from open flames and hot surfaces.
- Store in a cool, dry place and keep cartridge sealed until use.
Frequently Asked Questions
Do I need a primer before applying this polyurethane adhesive?
In most cases no primer is required, but certain substrates, vehicle models, or heavily weathered surfaces may still benefit from a primer. Always check the manufacturer's technical datasheet for vehicle-specific guidance.
How long until the adhesive is fully cured?
Cure time depends on temperature and humidity. The product provides a fast tack, but full mechanical strength can take from several hours to 24–48 hours under typical conditions. For critical load conditions (driving at high speed), follow the manufacturer's recommended safe-drive time.
Is this adhesive suitable for both professional and DIY use?
Yes — the cartridge format and included applicator make it accessible to experienced DIYers, while the formula and performance are engineered to meet professional installation standards.
